    [0001] FIELD OF THE INVENTION The invention relates to a device for heating a liquid comprising a heat generator and a liquid supply. State of the art To heat a liquid and in particular to heat sanitary water, it is known to dive a heating resistor inside a tank also called balloon. The heating resistor and the control system are configured so that the water temperature inside the flask is in a predefined temperature range to ensure optimal use. The heating of sanitary water represents a significant cost for all users and many innovations have been made to reduce this cost center.
    [0002] An interesting way to heat or preheat a liquid such as sanitary water is to use the calories produced by another device during its operation. These other devices are not primarily intended to produce calories. There is then recovery of thermal energy that would normally be lost.
    [0003] It is recognized that computer servers generate significant amounts of calories that must then be managed. An exemplary embodiment is described in document US 2007/0213000. Instead of supplying energy to a chiller configured to cool the computer server, it has been proposed to thermally couple the server to a coolant bath that will recover the calories produced. DE 102009038669 discloses a device in which thermal energy produced by an electronic device is partially recovered to heat water. US 2011/0132579 discloses a cooling device of a computer server by immersing the latter in a dielectric cooler liquid. The server is placed in a tank filled with dielectric coolant which will be heated by means of the calories released by the server.
    [0004] The cold dielectric liquid is injected through an inlet located in the bottom of the tank and comes out warmer through an outlet located in the top of the tank. A heat exchanger is coupled to the outlet of the vessel to recover some of the heat and transfer it to a specific area where this heat will be dissipated. The device is configured so that the temperature of the dielectric liquid is the largest possible. It has been observed that this configuration is not optimal. SUMMARY OF THE INVENTION It is found that there is a need to provide a heating device and method which is more efficient. This need is to be satisfied by providing a heating device comprising: A tank filled with a volume of electrically insulating heat-transfer liquid; at least one computer server provided with a power supply terminal and configured to be connected to another an electronic device disposed outside the tank, the computer server being immersed in the heat transfer fluid so that the calories produced by the computer server in operation are picked up by the coolant, - a draw system configured to draw heat transfer fluid located in the upper third of the heat transfer fluid volume by means of a circulator, 25 - At least one injector supplied with heat transfer liquid and configured to generate a coolant flow directed from the bottom to the top of the tank at the level of at least a server, - A heat exchanger configured to receive the heat transfer liquid from the heating system. drawing by means of a heating channel, o transferring the coolant to the at least one injector by means of a cooling channel, o heating a second liquid selected from an intermediate liquid or the main liquid by means of the heat transfer liquid the intermediate liquid being thermally coupled to the main liquid. It also aims to satisfy this need by providing a heating method comprising: - the operation of a computer server immersed in a heat transfer liquid present in a tank, the extraction of heat from the heat transfer liquid contained in the tank to a second liquid content in a tank by means of a heat exchanger, the second liquid being selected from the main liquid or an intermediate liquid thermally coupled to the main liquid, the injection of the coolant having passed through the heat exchanger on the computer server. BRIEF DESCRIPTION OF THE DRAWINGS Other advantages and features will emerge more clearly from the following description of particular embodiments given as non-limiting examples and illustrated with the aid of the appended drawings, in which FIGS. schematically represent two variants of a heating device according to the invention.
    [0005] Description of a preferred embodiment of the invention The heating device is configured to heat a main liquid 1 which is advantageously sanitary water. However, one skilled in the art will keep in mind that the sanitary water can be replaced by any other liquid requiring to be warmed.
    [0006] The heater has a primary heat source 2 which will produce the calories needed to heat the main liquid. The primary heat source is a computer server 2. It is also possible to provide several computer servers coupled or independent. The servers 2 may be the same or different. By computer server 2 is meant any electronic card comprising one or more processors, the circuitry necessary for its operation and intended to be connected to an external computer network. The computer server 2 is intended to be powered by a power supply 3 which provides an electric current. The computer server 2 is also intended to transmit and receive data through a computer network 4. The server 2 is intended to transmit the results of its work (calculation or any other operation) to another server remote from a tank 5 containing the server 2.
    [0007] The computer server 2 is, for example, a calculation server or a data storage server. The computer server 2 is disposed in a container also called tank 5. The tank 5 is at least partially filled with a volume of coolant 6 which will capture the heat released by the heat source or sources.
    [0008] During its operation, the computer server 2 will heat the coolant 6 which is contained in the tank 5. As the server or servers 2 are immersed in the tank 5, the coolant 6 is electrically insulating to prevent deterioration of the server 2 by short circuit. Advantageously, the heat transfer liquid 6 has a breakdown voltage greater than or equal to 40kV, which makes it possible to avoid the generation of a short circuit under standard operating conditions. Preferably, the coolant liquid 6 has a thermal conductivity greater than or equal to 0.1W.m-1.K-1 at 40.degree. C., which makes it possible to easily remove the heat from the computer server 1.
    [0009] Particularly advantageously, the heat transfer fluid 6 has a specific heat capacity greater than or equal to 2000 J.kg-1.K-1, which allows a good control of the temperature of the heat transfer liquid as a function of the thermal energy released by the server.
    [0010] It is also preferable to use a heat transfer fluid 6 which has a viscosity of less than 6x10-5 m2.s-1 at the temperature of 40 ° C. in order to ensure a good flow of the coolant 6 along the server 2 and therefore a good contact to recover heat.
    [0011] In order to facilitate the use of the coolant 6 and therefore of the tank 5 in various environments, it is advantageous to provide a heat-transfer liquid 6 having a flashpoint greater than or equal to 140 ° C. Advantageously, a radiator is mounted on the highly heat generating elements of the computer server 2 in order to increase the heat exchange with the heat-transfer fluid 6. The computer server 2 is then placed directly in the tank 5. In a Advantageously, the computer server 2 is completely immersed in the tank 5. Alternatively, it is possible to partially immerse it in the tank 5, taking care to immerse all the active parts 15 of the server 2, that is, that is, the parts that generate heat and are likely to degrade in the absence of forced cooling. The computer server 2 executes software that makes it possible to respond to the needs of customers materialized by another electronic device disposed outside the tank 5. The computer server 2 comprises a power supply terminal 20 which is intended to be connected to a source external power supply 3 outside the tank 5. The DC power supply of the server 2 and a portion of the computer network 4 are preferably located in the tank 5. The electrical protection elements of the servers may be out of tank. In a particular embodiment, the tank 5 comprises a lid which makes it possible to reduce the heat losses. Preferably, the tank 5 comprises a thermally insulating coating in order to avoid or reduce the heat losses via the side walls. The heating device also comprises one or more taps 7 of the coolant 6 to collect heated heat transfer liquid. As the hottest heat-transfer liquid 6 is in the upper part of the tank 5, it is particularly advantageous to draw the heat transfer liquid 6 in the upper third of the volume of the coolant 6 and more particularly in the upper 20%. the volume of coolant 6.
    [0012] In this embodiment, the drawing is predominantly vertical, which makes it possible to reduce the resistance to flow. The drawing is advantageously performed from the open part of the tank 5 without having to make a hole in the tank. This device makes it possible to draw by pulling at the hottest points of the upper surface of the tank the heat-transfer liquid 6 and thus to optimize the heat-transfer liquid flow 6 as a function of the hot spots of each server. Advantageously, several vertical drawing systems 7 are configured to draw heat transfer fluid 6 into the tank 5. The heated liquid 6 is sent to a heat exchanger 8 in order to transfer the calories to a second liquid which is the main liquid 1 or a intermediate liquid 9. The drawing can be carried out by any suitable drawing system 7. The transport of the heat transfer liquid 6 inside the heating device is carried out by means of a circulator 10. In a particular embodiment, the circulator 10 comprises a pump.
    [0013] The heat-transfer fluid 6 makes it possible to carry the heat transport from the computer server 2 to the main liquid 1. After drawing, the coolant 6 flows in a heating channel 11 which supplies the heat exchanger 8. In this way part of the thermal energy contained in the tank 5 is transferred to the second liquid which is also circulating in the heat exchanger 8. The second liquid may be the main liquid 1 or the intermediate liquid 9. In the heat exchanger 8, a portion of the calories leaves the coolant 6 for the second liquid. The coolant 6 cools and the second liquid heats up. The coolant 6 leaves the heat exchanger 8 by means of a cooling channel 11b. The cooling channel and the heating channel are made of first and second materials. In some embodiments, the first material is identical to the second material. Advantageously, the first material and / or the second material are made of polymer material.
    [0014] The cooling channel 11b feeds one or more injectors 12 which are arranged to send coolant 6 cooled on predefined areas of the server 2. Advantageously, an injector 12 is configured to project coolant 6 from the bottom of the server 2 to the top of the tank 5. In this configuration, the injector 12 creates a flow of heat transfer liquid 6 which goes up along the server 2 and captures the calories emitted. The injector 12 is supplied with heat transfer fluid 6 and is configured to generate a coolant flow 6 directed from the bottom to the top of the tank 5 at the server.
    [0015] In this configuration, at least one injector 12 is associated with a server 2, which makes it possible to generate a heat transfer liquid stream 6 specific to the server 2. The movement of a server 2 in the tank 5 or its withdrawal has a minimal influence on other servers 2 that may also be present. In the document US 2011/0132579, the injection of heat transfer fluid is related to the tank which makes it particularly difficult to adjust because the flow is dependent on the number of servers used and their position. If a server is removed or replaced by a server with different dimensions, the stream is changed and another server may be impacted. Also advantageously, one or more injectors 12 are directed towards active and very heat generating parts in order to efficiently cool the server 2. Again, it is preferable to orient the injector 12 towards the top of the tank 5 in order to that the coolant 6 follows a path in adequacy with the thermal gradient that exists in the tank 5. In this way, as and when it is heated, the heat transfer liquid 6 passes to the upper surface of the tank 5 to ensure the drawing heat transfer liquid 6 hottest. The use of an injector 12 arranged to target a specific area of the server 2 makes it possible to take into account the particular needs of the servers 2. For example, a server 2 carrying out a large quantity of calculations may have some hot spots that must be treated more particularly.
    [0016] The heating device may comprise a first injector 12 disposed under the computer server 2 and configured to cause a rising heat transfer liquid flow 6 inside the computer server 2. The heating device may comprise a second injector or several injectors 12 configured for projecting coolant 6 on a processor or a memory of the computer server 2. This configuration also allows greater flexibility on the amount of servers 2 present in the tank 5 and / on the general shape of the tank 5 which plays on the flow of liquid.
    [0017] Advantageously, each injector 12 is supplied individually, for example by means of a specific supply circuit 11. However, it is possible to provide for a supply circuit 11 to be specific to all the injectors of a server 2 or to all the injectors 12 for a hot point of the server 2.
    [0018] It is particularly advantageous to introduce the coolant 6 cooled in the tank 5 through the cooling channel 11b. The use of the cooling channel 11b makes it possible, on the one hand, to delay the heating of the coolant 6. On the other hand, the channeling of the cooled liquid 6 makes it possible to control the flow of the injectors 12 and therefore the efficiency of the cooling on the server 2.
    [0019] In a particular embodiment, the flow rates in the cooling channel 11b and in the heating channel 11a are defined by the circulator 10. The heating device is devoid of a control circuit ensuring servocontrol using data from the tank 5. The circulator works at constant flow rate or pressure. As a result, flow rates or pressures are constant. This embodiment is particularly robust, compact and inexpensive. In an alternative embodiment, the heating device comprises a control circuit 13 which is configured to modulate the flow rate or the pressure in the cooling channel 11b and / or in the heating channel 11a as a function of external parameters. These parameters are, for example, the temperature at one or more points of the tank 5, the temperature at one or more points of the computer server 2, the temperature of the main and / or intermediate fluid. The control circuit 13 is configured to modulate the flow rate or the pressure treated by the circulator 10. In a variant, the circulator 10 operates at a constant pressure or flow rate, but the control circuit 13 modulates the flow rate or the pressure in the different pressure groups. injectors 12 by means of switches and valves. The flow rate in the heat exchanger 8 can be controlled so that the temperature of the heated heat transfer liquid 6 is greater than a limit temperature. In this way, if the temperature of the heated heat transfer liquid 6 decreases, the control circuit 13 may decide to reduce the flow rate at the inlet of the heat exchanger 8 so as to prevent the heat transfer from reversing. In the opposite case, if the temperature of the heated heat transfer liquid 6 increases, the control circuit 13 may decide to increase the flow rate at the inlet of the heat exchanger 8 in order to avoid a significant increase in the temperature in the In a particularly advantageous manner, the flow rate in the heat exchanger 8 can be controlled so that the temperature of the heated heat transfer liquid 6 is lower than a limit temperature. The extraction of heat from the tank 5 is controlled so as to prevent the temperature in the tank from reaching a critical temperature. In a particular embodiment that can be combined with the previous embodiments, the heat exchanger 8 feeds several cooling channels 11b. The activation of the various cooling channels 11b and / or the flow rate in the various cooling channels 11b are controlled by means of a first set of valves 14b. The control circuit 13 may control the valves of the first set of valves 14b to promote cooling at a preferred location relative to another location.
    [0020] By way of example, if the server 2 comprises several processors, the control circuit 13 can control the cooling of one of the processors 1 as a function of the temperature of this processor and / or as a function of the computing load. In a variant, if several servers 2 are placed in the tank 5, it is possible to provide for the heat exchanger 8 to be used for the cooling of several servers 2. The drawing system 7 feeds several heating channels 11a by means of FIG. a second set of valves 14a. In another particular embodiment that can be combined with the foregoing embodiments, the heat exchanger 8 is supplied by a plurality of heating channels 11a. The activation of the different heating channels 11a and / or the flow rate in the various heating channels 11a are controlled by means of a second set of valves 14a. The control circuit 13 can control the valves of the second set of valves 14a to promote the drawing at a preferred location with respect to another location. This feature makes it possible, for example, to collect more coolant 6 in a warmer zone because the associated server 2 releases more heat than the others. By way of example, if several draw points are used in the same tank 5 or in several tanks 5, the control circuit 13 can control the extracted flow rate as a function of the temperature of the coolant 6 at the points of drawdown in the tank 5 or in each of the tanks 5 or the temperature difference between the different tanks 5. As previously indicated, the circulation of the different liquids is advantageously carried out by means of one or more circulators 10 which may comprise a pumping system. The circulator 10 is preferably disposed outside the tank 5 to facilitate maintenance of the device. It is also advantageous to place the heat exchanger 8 out of the tank 5 in order to obtain maximum cooling of the coolant 6 during the transfer of heat to the second fluid. Advantageously, the heating device comprises several tanks 5 inside which are mounted one or more servers 2. The cooling and heating channels are mounted so that the coolant liquid 6 can move from a tank 5 to another. In this way, it is possible to homogenize the temperature of the coolant between at least two tanks 5. In other words, the device comprises a plurality of tanks 5 each comprising, at least one computer server 2, an injector 12 and a sampling system 7. The control circuit 13 is configured to circulate the heat transfer liquid 6 between the plurality of tanks 5 so as to homogenize the temperature in the plurality of tanks 5. In general, the control circuit 13 is configured to separately control the flow rates in the multiple cooling channels 11b and heating 11a. The activation of the channels 11 is advantageously carried out by means of the control circuit 13 which actuates valves 14 and / or switches. This configuration makes it possible to simply control the flow rate in each of the channels 11. It is particularly advantageous to place the control circuit 13 out of the tank 5, which makes it possible to have a system that is flexible and easily replaceable in the event of failure or maintenance. It is also conceivable to provide a drawing system 7 associated with a heating channel 11a / cooling channel 11b, but this embodiment appears cumbersome. Advantageously, one or more filters 21 are arranged along the circuit taken by the heat transfer liquid 6. The filters 21 are configured to filter the solid clusters that can appear in the tank 5. They are advantageously arranged upstream of the point of drawing 7 and the circulator or circulators 10 to prevent these solid masses come to hinder or disrupt the operation of the circulators. The filter or filters will determine a surface in the volume of the fluid 6 as large as possible to limit the flow resistance of the fluid 6 and the need for cleaning or replacement of the filter or filters. The heating device preferably comprises a heat transfer liquid level detector 6 in the tank 5. The level detector 15 can be configured to detect whether the liquid level is lower than a first threshold value 15a, lower than a second value. threshold 15b or greater than a third threshold value 15c. The first threshold value 15a makes it possible to detect a leak in the tank 5 or more generally a loss of coolant 6, for example by evaporation. If the liquid volume becomes lower than the first threshold value, there is a risk that the server (s) 2 no longer bathe in a sufficient quantity of heat transfer fluid 6 to evacuate the heat produced. If the second threshold value 15b is reached, the order of shutdown of the server or servers 2 can be issued to ensure their integrity and to put the heater safe. The third threshold value 15c makes it possible to detect, on the contrary, that there is too much heat transfer liquid 6, which may be representative of an excessively large convection in the tank 5, of the presence of a boiling or of the failure in the circuit for moving the coolant 6 between several tanks 5. The third threshold value 15c can also be configured to detect an excessive expansion of the coolant 6.
    [0021] The heating device may also comprise one or more thermometers 20 configured to measure the temperature of the coolant 6 at one or more points of the tank 5 or the server 2. In the event of perforation of the tank 5, it is advantageous to have a retention tank (not shown) which recovers the heat transfer liquid flow 6. It is preferable to provide a heat transfer liquid detector 6 in the retention tank in order to overcome a possible failure of the liquid level detector in the tank 5 .
    [0022] In a particular embodiment illustrated in FIG. 1, the computer server 2 heats the heat-transfer liquid 6. The heat-transfer liquid 6 then warms the main liquid 1. The main liquid 1 can be stored in a first tank 16 to allow use at the request of the user. The calories extracted from the tank 5 are used to heat the main liquid 1 present in the first tank 16. The temperature in the first tank 16 increases as the main liquid 1 is not consumed. It is therefore particularly advantageous to size the capacity of the first tank 16 as a function of the maximum acceptable temperature in the first tank 16, the consumption profile of the main liquid 1 and the amount of energy produced by the server or servers 2. The main liquid temperature in the first tank 16 is dependent on the consumption of main liquid 1 and heat released by the servers 2 (that is to say, the calculation activity).
    [0023] In the advantageous case where the first tank 16 is devoid of additional heat source, the temperatures in the tank 5 and the tank 16 are dependent on each other. If no sampling is carried out in the first tank 16, the device is configured so that the temperature in the first tank 16 increases to equal the temperature in the tank 5.
    [0024] At the same time, the temperature of the tank 5 also increases because the cooling operated by the heat exchanger 8 is less and less effective. Once the main liquid sample 1 is taken, the heated main liquid is replaced by cold main liquid which decreases the temperature in the first tank 16.
    [0025] When the temperature in the first tank 16 decreases, the cooling of the server 2 is more efficient and the temperature in the tank 5 also decreases. There is then a correlation between the temperature of the tank 5 and the temperature in the first tank 16. In this configuration, it is possible to accurately estimate the temperature in the first tank 16 by means of the temperature in the tank 5 or conversely which facilitates the control of the installation. In an alternative embodiment, the main liquid 1 is taken continuously and is heated during its contact with the coolant 6 just before use. The temperature of the main liquid 1 is determined by means of the temperature of the coolant 6 and the efficiency of the heat transfer by the exchanger 8. Advantageously, the injection of heat into the first tank 16 is configured to creating a thermal gradient within the reservoir 16 between the heated main liquid and the unheated main liquid. The unheated main liquid is pulsed to feed the heat exchanger 8. This configuration allows optimal cooling of the server 2. The injection is advantageously carried out in the upper part of the tank 16 while the sampling is preferably carried out in the lower part. of the tank 16.
    [0026] More generally, it is advantageous to have a heated liquid injection point higher than the cold liquid sampling point. In another configuration illustrated in FIG. 2, the computer server 2 heats up the heat-transfer liquid 6. The heat-transfer fluid 6 then heats an intermediate liquid 9 which is in a second reservoir 17. The calories brought by the computer server 2 are stored in the second reservoir 17. The intermediate liquid 9 is then used to heat the main liquid 1 via a second heat exchanger 18. In this configuration, the main liquid 1 is heated by means of an intermediate liquid 9 which is itself heated by the coolant 6 and therefore by the server 2.
    [0027] This embodiment is particularly advantageous for heating domestic hot water. The intermediate liquid 9 is advantageously water to avoid any problem of contamination. In this case, the intermediate liquid 9 is water and this intermediate liquid 9 is connected to a second heat exchanger 18 configured to heat domestic hot water contained in a first reservoir 16. The main liquid 1 is then domestic hot water. Domestic hot water is stored in a storage tank 16 which is connected to a hot water distribution circuit which has one or more distribution points. Thus, a user can consume hot water that has been heated by means of the calories generated by one or more computer servers 2. The domestic hot water supply circuit comprises at least one pipe 19 connected to domestic hot water. a part to the heating device and secondly to one or more users via a supply valve or a supply valve.
    [0028] The end user can if he wishes to add another heating device.
    [0029] As before, the main liquid 1 can be used at the request of the user or continuously. Thus, the computer server 2 carries out the heating of the sanitary water via the coolant 6. This solution is easy to implement, particularly compact and very energy efficient.
    [0030] The use of a second intermediate tank 17 between the tank 5 filled with heat transfer liquid 6 and the first tank 16 containing the main liquid 1 allows a greater flexibility of operation, for example by storing a large amount of heat when it n There is no consumption of domestic hot water.
    [0031] The heat-transfer liquid supply circuit 6 is dissociated from the domestic hot water supply circuit so as to prevent the sanitary water from being polluted by the heat-transfer liquid 6 in the event of a leak in one of the transport elements and heat exchange. The intermediate liquid supply circuit 9 is also dissociated from the domestic hot water supply circuit and the heat transfer liquid supply circuit 6. This configuration makes it possible to change the heat transfer liquid 6 and / or the intermediate liquid 9 without risk. contamination of domestic hot water. The heater may include, in addition to the computer server 2, another heat source (not shown) which may be a conventional heat source. In this way, the calories extracted from the coolant 6 serve to preheat the sanitary water or the second tank 17. The other heat source is disposed outside the tank 5 and preferably in the first tank 16 containing the liquid Main 1 or in a heating device installed at the end customer's premises. In this way, the additional heat source can be used to heat the main liquid 1 if the temperature of the latter reaches a minimum value of use. It is then possible to perform preheating by the computer server 2. The calorie supplement is provided by the other heat source. The computer server 2 can be attached to the tank 5 by any suitable means. Preferably, the computer server 2 is dismountably mounted relative to the tank 5 so as to quickly replace the server 2 in case of failure. Even more preferentially, the computer server 2 is removably mounted for example by means of a hook which allows a rapid assembly and disassembly of the server 2. In a particular embodiment, the server is just placed on the side wall of the server. tank 5 which allows easy handling. A space between the lower part of the server and the bottom of the tank will preferably be left, so that the solid cluster potentials or liquid elements of higher density than the coolant 6 are stored at the bottom of the tank 5 without disturbing the circulation of the coolant 6 or the operation of the servers. Advantageously, the injector 12 is configured so as not to generate displacement of a first volume of the coolant 6 located in the bottom of the tank, preferably the first volume corresponds to a volume of coolant 6 being up to 1 cm from the bottom of the tank. This configuration allows the storage of a certain amount of water from condensation or other phenomena, solid elements such as labels or screws from servers or human interventions. The water and the solids stored in the bottom of the tank are not sent back to the server which avoids any short circuit. It is then possible to move the server 2 in another tank 5 without having to dismount bindings between the server 2 and the tank 5. It is also possible to add or remove a server 2 from the tank 5 by catching the support . The server 2 is installed vertically in the tank 5, that is to say that the length or its width is mainly oriented vertically. Particularly advantageously, the length of the server 2 is oriented vertically and so that the power supply terminal and the connection terminal to the computer network are in the upper part of the tank. Even more preferably, the power supply terminal and the connection terminal to the computer network are not immersed in the coolant liquid 6. In a particularly advantageous embodiment, the control circuit 13 is configured to carry out the extraction fast calories produced by the computer server 2 to prevent the temperature of the coolant 6 increases in the tank 5 beyond a threshold value. The heater is configured to quickly extract the calories produced in the tank 5 to the tank containing the second liquid. This result is obtained by configuring the heating device so as to minimize the thermal gradient between the temperature in the tank 5 and preferably in the upper zone of the tank 5 and the temperature in the tank containing the second liquid. Advantageously, the heating device is configured to have a thermal gradient of less than or equal to 20 ° C. This configuration makes it possible to reduce the temperature in the tank 5 and thus to increase the service life of the servers 2 and / or to increase the speed of operation of the servers 2. The transfer of calories is managed by the transfer of heat transfer liquid by means of the circulator 10 associated or not with the control circuit 13. The management of the value of the thermal gradient is regulated by the circulator 10 and / or the control circuit 13. The heating device is particularly advantageous because the server 2 allows a second type user to perform computing services of data calculation and / or data storage. These services can be performed just next to or several thousand kilometers without this altering the quality of the proposed IT service. When performing these services, the server 2 generates a large amount of thermal energy. This thermal energy is stored in the coolant 6 and is used to heat the main liquid 1. Depending on the case, the user of the server for computing services may or may not be the same as that of the main liquid .. The power consumed by the circulator 10 is low so that the power of the heating device is substantially equivalent to the power consumed by the computer servers 2. This configuration is particularly interesting because the energy consumed by the heating device to perform computation operations and the heating of the main liquid is less important than for an equivalent server performing the same computer calculation operations associated with its conventional cooling device.
    [0032] The energy released by the computer server 2 is no longer a lost energy but it becomes a source of heating or preheating for an application of another nature. It is then possible to save energy for heating the main liquid 1 by recovering the heat produced by another technological process. Part of the energy used by the computer servers 2 to perform the requested computer services is reused to heat the main liquid 1. This also eliminates the presence of a conventional cooling system comprising air ventilation which can be noisy and energy consumer. In an alternative embodiment which can be combined with the preceding embodiments, if several servers 2 are used in the same tank 5, it is possible to stop at least one of the servers 2 and to let the others operate in order to limit the temperature rise in the tank 5. The heating device can be arranged in an individual dwelling to deliver domestic hot water. It is also possible to place the heating device in a collective or tertiary residential building. It is still possible to use the heating device to heat a pool for example. Advantageously, if several servers 2 are used, the servers 2 are electrically connected to one or more energy sources 3. However, it is preferable to electrically dissociate the servers 2 in order to quickly stop a server 2 without hindering others servers 2 located in the same tank 5.
