    Temperature control unit for a gaseous or liquid medium
    The subject invention relates to a temperature control unit for tempering a gaseous or liquid medium by means of a number of thermoelectric modules, which are arranged between a base body and a heat sink, and in the base body, a media line is arranged through which flows through the gaseous or liquid medium.
    For accurate measurement of the fuel consumption of an internal combustion engine on a test bench, a precise conditioning of the temperature and the pressure of the fuel supplied to the internal combustion engine is necessary. The measurement of fuel consumption is often done with a known Coriolis flow sensor. An example of such measurement of fuel consumption can be found in US 2014/0123742 A1, which focuses on the conditioning of liquid fuels. Therein, the temperature of the fuel is controlled via a heat exchanger with a cooling liquid. Heavy load changes cause large fluctuations in fuel consumption and in the return temperature of the fluid (inlet temperature). However, such a heat exchanger is sluggish and allows only slow temperature changes. Thus, the conditioning described by means of heat exchanger for heavy load changes (input temperature changes) is unsuitable. This leads to the current state of the art that after such a load change a calming time must be maintained. During this time, the temperature is unstable and high-precision measurement is not possible for flow sensors. For a more independent of the input temperature changes operation, either the power density of the heat exchanger would have to be increased. However, this is not technically feasible and requires, if at all possible, a redesign of the heat exchanger. At constant power density would in turn result in a much larger footprint. Another possibility might be a more aggressive control behavior of the heat exchanger. However, this in turn means greater overshoot and undershoot and concomitantly poorer dynamics with regard to possible setpoint temperature changes. Increasing the heat exchanger would only help with liquids. For gaseous media, a change in flow will directly cause a pressure change and a setpoint temperature change. Thus, the heat exchanger would have to allow extremely fast setpoint temperature changes, but this is not practical feasible for a heat exchanger operated with cooling liquid. For this, the available power would have to be increased even more with constant mass, only to increase the power would have no benefit in this case. Alternatively, the regulator of the heat exchanger remains even more aggressive to adjust, but in turn, even greater over- and
    Undershooting would entail. An accurate and fast temperature control would not be possible.
    The dynamic temperature control by means of a heat exchanger, so if no constant temperature is set, is also still relatively inaccurate. Apart from this, such a heat exchanger requires additional components and controls for operating the heat exchanger, which also makes the system more complex.
    In DE 10 2010 046 946 A1 it is proposed to temper the temperature of the fuel in a conditioning plant by means of thermoelectric modules (so-called Peltier elements). This is due to the low storage masses achieved a highly dynamic temperature control possible with which the fuel can be both heated and cooled. This device is also aimed specifically at the conditioning of liquid fuels.
    For gaseous fuels, such as natural gas or hydrogen, there is the added problem that the gaseous fuel is typically under high pressure and, consequently, for use as fuel in an internal combustion engine, it must first be depressurized to a required, lower pressure , When relaxing the gaseous fuel, such as natural gas, but the fuel cools down sharply, which can be problematic for subsequent components of the conditioning, for example, by condensation and icing of the gas lines or other components in the gas line. Therefore, the gaseous fuel is usually heated before relaxing, so that by relaxing a desired temperature of the fuel results. Due to fluctuations in the pressure of the supplied gaseous fuel and also due to the dependence of the temperature after the relaxation of the composition of the gaseous fuel, which may also vary, the temperature control of the gaseous fuel before relaxing must be highly dynamic to the temperature after relaxing and before to be able to keep the flow measurement constant. In addition, the required heating power for controlling the temperature of the fuel is also heavily dependent on the current flow, which also makes a highly dynamic temperature control required with rapidly changing flow rates.
    On the one hand, such a highly dynamic temperature control requires a control method which is capable of carrying out highly dynamic (in terms of rapid temperature changes) control interventions and, on the other hand, a temperature control unit which is also capable of implementing the highly dynamic control interventions. Consequently, such a temperature control unit must be able to impress the required temperature changes on the fuel flowing through in a very short time. In addition, a high temperature stability is desired, even if under certain circumstances no high demands are placed on the dynamics of the Tempe raturregelung, since in certain applications a highly accurate and highly constant temperature control is needed. These requirements require a temperature control unit with a high heating and cooling capacity, which may also be necessary to change quickly between heating and cooling. Apart from that, a precise temperature control must be possible in order to avoid excessive overheating (either overheating or overcooling).
    DE 10 2010 046 946 A1 indicates that low thermal storage masses of the temperature control unit are advantageous for highly dynamic temperature control.
    US 6,502,405 B1 shows a heat exchanger element with Peltier elements for heating or cooling fuel in a vehicle. The heat exchanger element consists of a heat conducting block in which a fuel line is inserted meandering and which is thermally insulated on a first side. On the second side of the Wärmeleitblocks Pel-animal elements are arranged, which are thermally connected to a heat sink. The heat sink is typically designed with a large surface area and small memory mass to maximize heat dissipation capacity. In addition, a fan is still arranged on the heat sink in order to increase the heat dissipation capacity even further. Thus, the heat exchanger element of US Pat. No. 6,502,405 B1 is also designed for a low thermal storage mass in order to be able to dissipate heat quickly to the environment via the heat sink. Due to the meandering guidance of the fuel in the heat exchanger element but it also leads to an uneven heating of the fuel, which makes the temperature control difficult, since the Peltier elements are all driven with the same supply voltage. The uneven heating results in a higher temperature difference between the outlet temperature of the medium and the surface of the Peltier elements, which in turn leads to a lower maximum outlet temperature of the medium, since the Peltier elements can not be heated arbitrarily. Or it results in a lower maximum flow rate for a given outlet target temperature. Apart from that, more thermal energy is stored in the Wärmeleitblock by the higher temperature difference, which must be reduced again in the case of a desired temperature change, which makes the heat exchanger element but in turn slower. For a more uniform heating of the fuel, the individual Peltier elements would have to be matched to each other, i. different Peltierlemente along the fuel line, or the Peltier elements would have to be individually supplied and regulated. Both would be very expensive and therefore disadvantageous.
    However, the above-mentioned problems can basically occur with any gaseous or liquid medium which is to be tempered in a temperature control unit, and not only with fuel.
    Based on this prior art, it is an object of the subject invention to provide a temperature control unit for a gaseous or liquid medium, which allows a particularly highly dynamic and accurate temperature control of the medium.
    This object is achieved in that the mass ratio of the thermal storage mass of the heat sink to the thermal storage mass of the base body and disposed therein media line in the range of 0.5 to 1, advantageously in the range of 0.7 to 0.8, and very particularly advantageous with 0.75 is chosen.
    It has been found that for a highly dynamic temperature control of a medium by means of a tempering unit according to the preamble of claim 1, especially when a rapid and frequent change in the direction of the heat flow is required, too low a storage mass, as suggested by the prior art, disadvantageous is. Surprisingly, it has been found that a certain mass ratio between the mass of the heat sink and the mass of the main body together with the media line arranged therein is advantageous for the temperature control. The reason for this is evidently that a thermal storage mass is formed by the larger mass of the heat sink and thus not too fast thermal energy is released to the environment. This stored energy can then be used to assist in heating the fuel as needed, thereby allowing the temperature to be controlled more quickly and accurately.
    A compact embodiment of the temperature control unit is obtained if a groove is provided in the main body into which the media line is pressed. For a very efficient temperature, it is advantageous if the media line is arranged spirally guided in the base body from outside to inside. By this arrangement of the media line in the main body in the form of a catchy spiral, a particularly uniform and efficient temperature control of the medium can be achieved. Due to the spiral shape, the temperature control can be made very compact, since the spiral paths can be arranged close together. As a result, a thermoelectric module can also cover several spiral paths, which improves the efficiency of the temperature control unit and the uniformity of the heating. This allows a particularly highly dynamic, accurate and stable temperature control of the medium can be achieved.
    An efficient temperature control is further supported if the number of thermoelectric modules are arranged in a plurality of circumferentially aligned rows on the base body, wherein the module heating of a radially outer lying thermoelectric module is greater than the Modulheizleistung a radially further inside thermoelectric module. Thus, the inflowing medium from the outside in the radially outer
    Temperature range can be tempered with high heat output, which allows for strong and rapid temperature changes. The modules are preferably coordinated so that the temperature spread at maximum flow between module surface and medium outlet temperature is minimal. As has been shown, this is the case when all modules have almost the same surface temperature. Due to the circumferential arrangement, the thermoelectric modules are within a range of home from almost the same temperature. Only the different rows would have to be adjusted in this regard, which, in contrast to a meandering arrangement of the media line represents a significant simplification, since for the same result (minimum temperature spread) not all thermoelectric modules must be aligned.
    In addition, the module heating power can be optimally adapted to the conditions and it can be installed radially inside modules with smaller module heating.
    In order to concentrate the thermal energy in the base body and to prevent excessive outflow of thermal energy, the base body is advantageously surrounded by a base body shell, wherein over the circumference of the base body a plurality of radial connecting webs are arranged, which are connected to the base body shell. This also increases the efficiency of the temperature control unit. This can be further improved if the body shell is made partially hollow, since thus an even better thermal insulation between the body and the environment is achieved.
    It can be advantageous to arrange a cooling line in the heat sink, through which, as required, cooling medium flows to cool the heat sink in order to be able to dissipate heat more quickly from the heat sink. This can be particularly useful for gases without pronounced Joule-Thomson effect or in liquid media, since in these cases, a frequent reversal of the thermoelectric modules may be necessary. The cooling line is advantageously arranged spirally again.
    The subject invention will be explained in more detail below with reference to Figures 1 to 7, which show by way of example, schematically and not by way of limitation advantageous embodiments of the invention. It shows
    1 is a perspective view of the temperature control unit according to the invention,
    2 shows a view of the temperature control unit with the heat sink removed,
    3 and 4 views of the main body of the temperature control,
    5 shows a view of the media line in the temperature control,
    6 shows a further advantageous arrangement of the media line in the main body and Figure 7 shows a temperature control unit with a cooling line in the heat sink.
    FIG. 1 shows a perspective view of the temperature control unit 1 according to the invention. The temperature control unit 1 consists of a base body 2, on which also any fastening elements 3, such. Feet in the illustrated embodiment, may be provided for securing the temperature control unit 1. A thermal insulation element 4 is arranged on a first side of the main body 2 and a heat sink 5 on the opposite second side. A media line 6 through which a gaseous or liquid medium, such as e.g. Fuel flows, which is tempered in the temperature control unit 1 to a desired temperature. The media line 6 has for this purpose an input terminal 10 and an output terminal 11, whereby the flow direction of the medium is determined by the temperature control unit 1 (indicated in Figure 1 by the arrows).
    FIG. 2 shows the temperature control unit 1 with the heat sink 5 removed. This shows a number of thermoelectric modules (Peltier elements) 7, which are arranged on the base body 2. As is known, a thermoelectric module 7 is a semiconductor element which is arranged between a first heating surface 9a (not visible here in FIG. 2) facing the main body 2 and a second heating surface 9b (here facing the heat sink). Depending on the polarity of the electrical voltage supplied to the semiconductor element, either the first heating surface 9a is warmer than the second heating surface 9b, or vice versa. After the structure and function of such thermoelectric modules 7 are well known and such thermoelectric modules 7 are commercially available in different performance classes, it is not discussed here in detail.
    Thus, with such a thermoelectric module 7 depending on the polarity of the supply voltage, which is supplied for example via the terminals 8, both heated and cooled. "Heating" here means that heat is supplied to the main body 2 and "cooling" that the main body 2 heat is removed. Thus, with the thermoelectric modules 7, the heat flow between the base body 2 and the heat sink 5 can be influenced.
    The thermoelectric modules 7 are via a first heating surface 9a (not visible in Figure 2) directly or indirectly (for example via a heat transfer element to improve the heat conduction) in thermal contact with the base body 2. The heat sink 5 is at the second heating surface 9b of thermoelectric module arranged and is in thermally conductive contact, again directly or indirectly, with this second heating surface 9b. The heat sink 5 and the main body 2 are not arranged adjacent to each other to avoid a direct thermally conductive contact between the heat sink 5 and body 2 (as shown in Fig. 1 seen).
    The basic body 2 is shown in detail in FIGS. 3 and 4, which show different views of the main body 2. 3 shows the side of the main body 2, on which the thermoelectric modules 7 are arranged. The main body 2 is essentially formed from a base plate 20, which is surrounded along its circumference by a main body shell 21. The main body shell 21 is connected via radial connecting webs 22 with the base plate 20, wherein the connecting webs 22 are arranged distributed over the circumference of the base plate 20. In the circumferential direction between the connecting webs 22 thereby cavities 23 are formed, which act as thermal insulation between the base plate 2 and the main body shell 21. By the connecting webs 22 and the cavities 23, the heat flow from the base plate 20 in the main body shell 21 is significantly reduced. As a result, the heat introduced by the thermoelectric modules 7 into the baseplate 20 remains concentrated therein and flows only to a slight extent via the main body shell 21 to the environment. This also ensures that the base body shell 21, and thus also the temperature control unit 1, does not overheat on the outside, and that parasitic heat flows which reduce the performance and dynamics of the conditioning are kept as small as possible.
    The main body shell 21 may additionally be made partially hollow by 21 circumferential slots 24 are incorporated in the main body shell, which also form cavities for additional thermal insulation.
    4, the other side of the base body 2 is shown. Here it can be seen that at the back of the base plate 20, a preferably spiral groove 25 is formed, in the assembled state, the media line 6 is pressed. The groove 25 forms in the base body 2 a catchy planar spiral (Archimedean spiral, logarithmic spiral). The media line 6 is preferably guided spirally inwards from the outside and emerges from the temperature control unit 1 in the central inner region of the base plate 20, the media line 6 being deflected out of the plane of the spiral when exiting, preferably by about 90 ° the media line 6 easy to be able to lead out of the temperature control unit 1. In principle, however, any other guidance of the media line 6 in the main body 20 is conceivable.
    The use of a media line 6 in the form of a catchy spiral is very expensive to produce since the media line 6 extends in all three dimensions in this case.
    In an alternative embodiment, the media line 6 is arranged on the base body 2 in the form of a two-flighted planar spiral (also called Fermat's spiral), as will be described with reference to FIG. For this purpose, in turn, a corresponding ge-shaped groove 25 may be formed for receiving the media line 6 in the main body 2. Via a first spiral passage 27, the medium in the media line 6 is guided spirally radially from the outside to the center inside. Centrally inside, the first spiral passage 27 is connected to a second spiral passage 28, via which the medium in the media conduit 6 is guided spirally from radially inward to radially outward. Due to the double-threaded design of the groove 25 are always radially a first spiral passage 27 and a second spiral passage 28 adjacent to each other. The medium is thus supplied radially on the outside via the input terminal 10 and discharged radially outward via the output terminal 11. The double-flighted spiral has the advantage that the media line 6 does not have to be deflected out of the plane of the spiral, which is easier to manufacture. For the double-flighted spiral has the disadvantage that the inflowing medium cools the outflowing medium, which requires a little more power and a less uniform heating is feasible. The temperature spread becomes larger, but the thermoelectric modules of a row, in the case of tuned modules, still all approximately the same temperature.
    Of course, the catchy or double-flighted spiral need not necessarily be designed as a circular spiral, but may also have other shapes, such as rectangular, square, etc., have. Due to the spiral shape, the temperature control unit 1 can be made very compact, since the spiral passages can be arranged close to each other. This can be accommodated in a small space a lot of meters on the media line 6, which increases the available surface for temperature control of the medium flowing through the media line 6 medium.
    In order to realize a tight packing of the media line 6, 6 prescribed minimum bending radii must not be exceeded in the shaping of the media line. A meandering guide the media line would be disadvantageous in this regard, since the required bending radii for a dense packing are considerably smaller than in a spiral course. With increasing pressure requirements by the media line 6 increases due to the required increase in wall thickness usually the minimum bending radius. A meander-shaped guide therefore has a particularly disadvantageous effect on high pressure requirements, as in the present case.
    5 shows still the thermal insulation element 4 with the advantageous catchy spiral-shaped media line 6, which is pressed into the base body 20 in the assembled state. The thermal insulation element 4 ensures that the heat introduced by the thermoelectric modules 7 into the base plate 20 remains concentrated therein and is not released to the environment via the end face of the temperature control unit 1.
    The thermoelectric modules 7 are preferably circular, or adapted to the spiral shape, and in several rows (ie at different radial distances) on the base plate 20 is arranged (Fig.2). Thus, more thermoelectric modules 7 can be arranged radially on the outside due to the resulting larger circumference. The inflowing medium is thus tempered in the radially outer region with high heating power, which enables strong and rapid temperature changes. It is further advantageous if a thermoelectric module 7, which is arranged radially further inside, has a lower module heating power, as a thermoelectric module 7, which is arranged radially further out. After the media line 6 is preferably guided in a spiraling manner inwards, fewer and weaker (in the sense of less module heating power) thermoelectric modules 7 extend radially inwards for temperature control of the medium. Thus, the temperature of the medium can also be optimized by the arrangement and selection of the Modulheizleistung the individual thermoelectric modules 7 and it can be achieved a very uniform heating of the medium.
    If an electrical supply voltage is applied to a thermoelectric module 7, as is known, one of the heating surfaces 9a, 9b of the thermoelectric module 7 is cooled, while at the same time the opposing heating surface 9a, 9b is heated. The maximum temperature spread between the heating surfaces 9 a, 9 b depends on the operating temperature (temperature on the warmer heating surface) of the thermoelectric module 7. The higher the operating temperature, the higher the maximum achievable temperature spread between cold and hot heating surface 9a, 9b. Thus, with available thermoelectric modules 7 temperatures of up to 200 ° C can be achieved on the hot heating surface, the cold heating surface does not exceed 100 ° C. By simply reversing the supply voltage, a highly dynamic control of the temperature is made possible. This control is supported in the temperature control unit 1 according to the invention by the heat sink 5 in the heating mode, so when the medium is to be heated in the media line 6, is used as a buffer memory. For this purpose, however, the thermal storage mass is not as small as possible, as suggested in the prior art, but it is a certain storage mass desired to realize that.
    It has been found to be advantageous if the mass ratio of the thermal storage mass of the heat sink 5 to the thermal storage mass of the base body 2 and disposed therein media line 6 in the range of 0.5 to 1, advantageously 0.7 to 0.8, is selected. A particularly advantageous temperature controllability of the temperature control unit 1 was found at a mass ratio in the range of 0.75, or at a mass ratio of 0.75. For example, a tempering unit 1 that was tested had a thermal storage mass of the heat sink 5 of 5.4 kg and a thermal storage mass of the base body 2 and the media line 6 arranged therein of 7.2 kg, which resulted in a mass ratio of 0.75.
    In an embodiment as in Figure 3 or Figure 6, in which the base body shell 21 is thermally separated from the base body 2 via cavities 23, the mass of the base body shell 21 is not calculated to the thermal storage mass of the body. Likewise, the insulating element 4 is not part of the thermal storage mass of the main body. 2
    With constant heating demand of the temperature control unit 1, ie with a constant voltage supply of the thermoelectric modules 7, the thermoelectric modules 7 establish a stable temperature spread. As soon as less thermal energy or heat is required for tempering the medium, the supply voltage is reduced at the thermoelectric modules 7, whereby the temperature spread is lower. Thus, the temperature at the voltage applied to the base plate 20 heating surface 9a of the thermoelectric module 7. At the same time, the temperature rises at the opposite heating surface 9b. This results in a temperature gradient between the heating surface 9b and the cooling body 5 resting thereon, whereby heat flows into the heat sink 5 and is not dissipated there immediately due to the thermal storage mass of the heat sink 5 to the environment, but is cached (at least for a limited time) , This cached thermal energy is the temperature control or the temperature control unit 1 as a support available when more thermal energy is required to control the temperature of the medium again. In this case, the supply voltage would be raised again, so that the temperature difference at the thermoelectric modules 7 increases again. Thus, the temperature at the heating surface 9b, against which the heat sink 5 abuts, decreases with respect to the temperature of the heat sink 5. This creates a reverse temperature gradient, which leads to the thermal energy stored in the heat sink 5 (heat) flowing into the main body 2 and thus supporting the thermoelectric modules 7. Due to the thermal storage mass of the heat sink 5 can thus be reacted very quickly and accurately with the temperature control unit 1 to load changes or temperature changes and a typical overheating can be largely avoided. For this purpose, the thermal storage mass of the heat sink 5 with respect to the thermal storage mass of the base body 2 and disposed therein media line 6 but not too large or too small.
    The total surface of the heat sink 5 should be designed as a function of the expected operating temperature so that the heat stored in the heat sink 5 is not released too quickly to the surface, but remains sufficiently long stored in the heat sink 5. The surface is thus not as large as possible and optimized to dissipate the heat as in conventional heat sinks, but on the contrary so that the heat is stored in the heat sink 5.
    A complete thermal insulation of the heat sink 5 from the environment would also be disadvantageous because in the case of frequent reversals, the temperature could heat up in the heat sink 5. For different media, if necessary, the material of the media line 6 and the heating power of the thermoelectric modules 7 are adapted. The general basic principle with the heat sink 5 as a storage mass to support the temperature control unit 1 remains untouched. For certain gaseous media, such as e.g. Natural gas, it comes due to the Joule Thomson effect to a strong cooling by the necessary pressure release. In these gases, the temperature control unit 1 must generally only preheat the gaseous medium. Cooling of these gases by the temperature control unit 1 is usually not required. Thus, it is usually sufficient for these applications to work only with the temperature spread of the thermoelectric modules 7. A reversal to change from heating to cooling is rather unnecessary.
    Other gaseous media, such as e.g. Hydrogen, do not show this pronounced effect of strong cooling by the necessary pressure release. On the contrary, it may also come to a warming by the pressure release. When tempering liquid media often no pressure release is necessary because the liquid medium is already present with the right pressure.
    For gases without pronounced Joules Thomson effect or liquid media, the temperature control unit 1 must therefore often switch between heating and cooling the gaseous medium in order to keep the temperature constant depending on the pressure and the flow. In particular, during cooling, it may be that due to the lower surface of the heat sink 5, the resulting heat, especially the waste heat of the thermoelectric modules 7, can not be dissipated quickly enough. Therefore, when using the temperature control unit 1 with such gaseous or liquid media, it may also be provided to additionally cool the heat sink 5 as required. For this purpose, a cooling line 12 may be introduced into the heat sink 5, is passed through the cooling liquid for additional cooling of the heat sink 5. Such an embodiment is indicated in Fig.7. The cooling line 12 can again be arranged in the heat sink 5 in the form of a catchy or double-flighted spiral, as described above with respect to the media line 6. For this purpose, the heat sink 5 can also be designed in several parts in order to be able to introduce the cooling line 12. Of course, other embodiments of the cooling line 12 are conceivable.
    In the exemplary embodiment according to FIG. 7, grooves 31 are incorporated in a heat sink main body 30, for example milled in to form the cooling line 12. The grooves 31 are vorzugswiese as described spirally incorporated. The heat sink main body 30 with the grooves 31 is covered with a heat sink cover 32 to form the heat sink 5.
    If a separate line is used as cooling line 12 in the heat sink 5 (similar to the media line 6 in the main body), then the cooling line 12 would also be part of the thermal storage mass of the heat sink fifth
    In order to connect to the cooling line 12 in the heat sink 5, a Kühlmediumzuführanschluss 34 and a Kühlmediumabführanschluss 33 may be provided on the heat sink. Preferably, the cooling medium is supplied from the inside and discharged centrally outside.
