    专利说明:

    The invention relates to a heating heat sink according to the preamble of claim 1.
    Radiators with fan units are known. Such radiators are often equipped with convection plates. With such radiators, a power increase should be achieved with fans even at low operating medium temperatures in order to use the radiators efficiently for regenerative energy sources can.
    When the invention is described with reference to radiators, it is understood that such radiators can also be used as a heat sink for cooling purposes. The term radiator thus also heat sinks are to be understood, which represent nothing else than radiators, where the temperature of the equipment is set correspondingly low. According to the invention, therefore, the cooling capacity of radiators can be improved.
    Radiators according to the invention may comprise at least one heating plate or a number of mutually opposite heating plates. In multi-layer radiators, the individual heating plates are arranged parallel to each other and connected by line or valve fittings. It is possible to provide Konvektorbleche at multilayer radiators on the opposite surfaces of the heating plates.
    Under a hotplate is understood an independent radiator element or a radiator, or shows an arbitrarily shaped, plate-shaped structure of the basic basic shape forth. Such a heating plate may, for example, have a collecting duct located at the top and bottom, which collecting ducts are connected by fluid channels. However, such a heating plate may also have on their outer sides planar heating surfaces, which are achieved, for example, that Abdeckpiatten be mounted on a collecting ducts and fluid channels radiator. Such a heating plate can also be created by arranging a number of plate-shaped heating channels directly next to each other and fluid-conducting, thus creating a plate-shaped heating element. A heating plate used according to the invention generally has a rectangular or square shape.
    Convection sheets can be arranged continuously from one side edge to the other side edge of a heating plate. The convection plates may also be formed interrupted or present in sections. On the height of a heating plate and a plurality of rows of Konvektionsblechen can be arranged, which are spaced correspondingly. In the use position, such radiators or the heating plates are with their lower and upper edge parallel to the ground, that is horizontal, arranged; the side edges are vertical. Such radiators are usually flowed through from bottom to top, that is in the vertical direction with air and the air flows over the plate surfaces and / or over the surfaces of the convection plates.
    It is an object of the invention to ensure a simple and reliable installation of fan units. The assembly and any disassembly of the fan units in case of service should be able to be done quickly without great effort.
    This object is achieved with the features cited in the characterizing part of claim 1.
    Apart from a simple and rapid assembly and disassembly of the fan units, a position for the fan units is given in which they are best protected against damage during operation of the radiator, since the support for the fan units is at a height level, in front of the heating surface of the heating plate and the wearer does not project the heating plate down or sideways. If the fan units are arranged between two heating plates, the fan units are completely protected and there is also an aesthetic sight, since the fan units are not visible and covered arranged. If the carrier is fastened to a radiator formed by a single heating plate, then this is usually done on the wall-side in the operating position surface of the radiator. The assembly and disassembly of the fan units are, however, by means of elastically bendable connection units in a simple way to the side or down possible, even if the radiator are in niches.
    According to the invention it can be provided that the carrier comprises at least one profiled bar and / or a profile strip and / or a support plate and / or a rail and / or that the fan units and / or the connection units are auf- and / or inserted on the carrier. The shape of the carrier can be varied. Advantageously, however, the carriers have a simple cross-sectional shape in order to push the fan units by means of the connection units or directly on the support and clamp or to be able to insert into opposing parts of the carrier or postpone or hang on support can.
    It is possible that the support on the convector plate bearing surface of the heating plate or a radiator with two opposing heating plates on one or on the two opposite surfaces of these heating plates or on the carried by a heating plate convection plate or on the opposite heating plates worn Konvektionsblechen is attached. This type of attachment can be done without much effort and can be made at the factory or on site. The carriers can be clamped between two heating plates or hung on the heating plates provided tabs or projections. Other possibilities of attaching the carrier to the surfaces of the heating plates and / or Konvektorblechen are conceivable.
    It is possible that the individual adjacent fan units are connected to each other with individual connection units or that a continuous connection unit is provided, to which the individual fan units are fastened at predetermined intervals. It is also possible to fix the individual fan units on connecting elements and to connect these connecting elements with intermediate connecting elements to form a chain. Depending on the number of fan units provided and the length of the radiator, it may be advantageous to choose a continuous connection unit or to connect the fan units with individual connection units. It is possible that the individual connection units are formed of equal length and thus the fan units are arranged at equal intervals along the carrier or that the fan units are arranged at equal intervals along the continuous connection unit. It is thus achieved that the distances between the fan units can be predetermined by the length of the individual connection units and / or by the position of the fan units on a continuous connection unit.
    Since the connection units are bendable, the fan units with the connection units can be moved laterally out of the radiator, even if only little space is available at the side of the support or the radiator. Also, a decrease of the fan units downwardly from a horizontally disposed support is easily possible because the bendable connection units make it possible to withdraw the fan units from the support and to immediately transfer them to another altitude with respect to the support.
    It is advantageous if the individual connection units or the continuous connection unit are elastically bendable at least in one plane, which lies parallel to the surface of the respective heating plate or parallel to the flow direction of the fan units. It is thus possible to arrange the carrier in places where the fan units cause the best efficiency, but without having to take into account that the fan units must be mounted and possibly also dismantled and without having to pay attention to spatial conditions, such as this is in radiators arranged in Fensterische the case.
    Good efficiency is obtained when the support is positioned or secured beneath a convection plate located or secured to the airfoil surface of the heating plate, and / or when the flow area of the fan units sweeps the opposed surfaces of two opposing heating plates coated with Konvektionsblechen surfaces of opposing heating plates or provided with a convection plate surface of a hot plate.
    It may be advantageous if the individual connection units are tension- and / or pressure-resistant, and / or if the continuous connection unit or the individual connection units are formed by band-shaped or plate-shaped components, which optionally the space between two mutually oppositely arranged heating plates only partially fill and / or provided with air passage openings. For mounting the fan units, it is advantageous if the connection unit or the individual connection units are made pressure-resistant, since the fan units connected by means of the individual connection units or the continuous connection unit can thus also be pushed onto a carrier or pushed into a carrier , The disassembly is easily possible by the connecting units pulled out and thus removed or withdrawn from the carrier.
    Furthermore, however, such connection units should not affect the air flow over the height of a heating plate or between heating plates, which is why it is provided that the connecting elements occupy only a small space between heating plates or in front of a heating plate and / or provided with air passage openings. This avoids any impairment of the air circulation through the connection units.
    It is also possible for the fan units to be detachably connectable to the connection units. Thus, the formation of different length fan unit chains is easily possible.
    It proves to be advantageous if for connecting the connection units with the fan units and / or for connecting the connection units and / or the fan units with the respective carrier to the connection units and / or to the fan units connecting elements and / or projections, bolts, seats, recesses and / or clamping devices are formed or arranged. Thus, it is easily possible to replace defective fan units or defective connection units from a chain of spaced apart and connected by means of the connecting elements fan units. The manner of the connection can be carried out in many ways.
    Since the fan units are electrically operated, it is advantageous if cable carriers or cable holders are arranged or formed on the connection units and / or the fan units.
    The connection units may be band or strip-shaped. It is expedient if the width of a connection unit, perpendicular to the respective surface of the heating plate, corresponds to or falls below the width or the diameter of the fan units. It is also advantageous if the individual connection units are rectangular when seen in plan view and have at least one, preferably centrally located, air passage recess.
    The connection units can be created in large numbers or in series and can be easily connected to fan units and affect the air circulation in a very small amount.
    It is further provided that the fan units and / or the continuous connection unit or the individual connection units from a narrow side of the heating plates are pushed or pushed onto the carrier and / or that the ends of the carrier of at least one narrow side of the heating plates for insertion or postponement accessible by fan units. The assembly and disassembly is thus simplified. The fan units can also be inserted or removed below or from the lower longitudinal side region of the radiator forth or from below between opposing heating plates.
    It can be provided that the fan units convey air by suction or blowing over the surface of the respective heating plate or the surfaces of mutually opposite heating plates. In both cases, the use of connection units for the assembly and disassembly of the fan units is advantageous.
    In a possible embodiment it can be provided that the fan units is mounted on a connecting unit designed as a carrier plate and this carrier plate is connected to further individual connection units and can be pushed or pushed onto the carrier with fastening units carried by it. The support plate facilitates the connection and the mounting of the fan units.
    It is advantageous if the connection units lying between the fan units are shorter than the connection units carrying the fan units. Thus, the number of fan units can be increased along the carrier. Such connecting units wind provided with air passage openings or narrow or misplacing the gap between opposing heating plates only to a small extent. It is also possible to clamp the fan units and / or the connection units on the carrier, preferably from below, and to spend by shifting on the carrier in the desired position. This procedure is particularly advantageous when arranged in the lower edge region of the radiator supports. • «* · * * * • • * * * * ··· *» fl fl * ·· »· ·» · ·
    In the following the invention will be explained in more detail with reference to the drawing, for example. Figs. 1a to 1f show examples of assembly and disassembly of fan units on supports fixed to heating plates. Fig. 2a, 2b and 2c and 3a, 3d and 3c show the attachment of fan units by means of a carrier plate on a carrier, which is arranged between two heating plates. 4, 5 and 6 show different embodiments of carriers and of connecting elements which can be pushed or pushed onto the carrier. Fig. 7 shows an embodiment of a connection unit which can be clamped onto a carrier, wherein the carrier is fastened to the convection plates of two heating plates. 8a, 8b and 8c show the assembly of fan units between two heating plates and between superimposed rows of Konvektorblechen. 9a, 9b and 9c show further embodiments of a support for holding fan units.
    1a, 1b and 1c show a schematic longitudinal sectional view through a two-layer radiator, that is, a radiator comprising two heating plates 1, 1 ', which are in fluid communication with each other via valve sets 10. Each of the two heating plates 1,1 'carries two longitudinal Konvektorbleche 6, which are arranged one above the other at a distance from each other. Between the opposing surfaces 11, 11 'of the two heating plates 1,1' is a carrier 3. This carrier 3 may be attached to the two heating plates 1, T or even on only one of these two heating plates 1, T. The carrier extends in the longitudinal direction of the respective heating plate 1, 1 'in the space between the overhead Konvektorbtech 6 and the lower convection plate 6. As indicated schematically, 3 fan units 4 are supported by the carrier. The fan units 4 can be applied and inserted from a narrow side onto the carrier 3 or its end regions or also from both sides. By pulling out of the space between the two heating plates 1,1 ', the fan units 4 can be removed from the carrier 3 and removed from the radiator. The fan units 4 are connected to each other by means of connection units 5, which are shown only schematically in these figures, and can be hung or pushed together suspended in the form of a chain. Accordingly, train or pressure is applied manually to the fan units 4. The fan units 4, which are connected by means of the connecting elements 5 and hang against each other, can be pushed onto the support 3 or inserted into it and are supported by it. You can also be secured by clamping on the support 3. The fan units 4 are used to promote air according to the flow direction 22, as shown in Fig. 1b, on the inner surfaces 11, 11 'of the two heating plates 1, T, to improve the circulation and heat dissipation of the radiator. t «· ♦ φ% φ« »·« · · # · ♦ «» «« ♦ • «· 7 · · · · · ♦ ·« «« Φ · t <* · * »« • «&lt; «» · · «« Μ «Μ
    Fig. 1 d, 1 e and 1 f show the arrangement of a carrier 3 and two carriers 3 in front of the surfaces 11, 11 'of the heating plates 1,1'. It can be seen that the carrier or carriers 3 ends at a distance in front of the valve sets 10 arranged laterally or centrally on the two heating plates 11, 11 '. According to FIG. 1f, the two carriers 3 end in front of the centrally located valve assembly 10.
    In order to enable a sliding or removal of the fan units 4 connected to the connection units 5 on or from the carrier 3, the connection units 5 are designed elastically bendable.
    In principle, the connecting units 5 may be made of a material which, although bendable and tension-resistant, is not pressure-resistant. If a non-pressure resistant material, e.g. a braided band is used, it is necessary to insert the fan units 4 to be placed on the carrier 3 in such a manner that tension is applied to the first or each previously inserted fan unit 4 or the respective connection unit in the direction of the interior of the heater and thus the subsequent fan unit 4 is mounted on the carrier 3. When using pressure-resistant material, the fan units 4 and / or the connecting units 5 can be inserted by pressure loading of the respective outer unit. Accordingly, train or pressure is applied manually to the fan units.
    Fig. 2a, 2b and 2c show in schematic section a between two heating plates 1,1 'arranged carrier 3, to which a connection unit 5 in the form of a support plate 15 by clamping on the carrier is mounted and pushed out.
    The carrying a fan unit 4 supporting plate 15 is suspended from the carrier 3 and has an extension in a direction perpendicular to the two heating plates 1,1 'such that the support plate 15 this heating plates 1, T relatively far approaches. However, as can be seen in Fig. 2b, this connection unit 5 has at least one recess 12 to allow air to pass through the connection unit 5. This passage of air takes place in addition to the air flow caused by the fan units 4, which runs in the direction of the arrow 22. The fan units 4 are connected to each other via the individual connection units 5. The connecting units 5 are connected to the fan units 4 via suitable fastening means 13 of any kind. These can u.a. Pin, recesses or locking units, etc. are provided. It is essential that the connecting units 5 connect the individual fan units with high tensile strength and allow a deflection of the fan units 4 connected to a chain, if these are pulled off or pushed or pulled or pulled from the carrier 3. Fasteners 13 may also serve to juxtapose the individual ones.
    lying connection units 5, which optionally have the shape of a support plate 15, to each other, in particular releasably connect.
    In the schematic side view, which is shown in Fig. 2c, it can be seen that the individual connection units 5 are clamped by means of terminals 7 on the support 3 and carry pin 13, which are inserted into recesses of the fan units 4. The connecting units 5 are elastically bendable and preferably made of plastic.
    As shown in FIG. 2 a, the connection units 5 and / or the fan units 4 may have carriers or holders 9 for the power cables 15 for the fan units 4.
    2a to 2c show an embodiment with the smallest possible chain length of a fan unit chain with only two fan units 4 and a single connection unit 5. This shortest fan unit chain can be extended by connecting connection units 5 and fan units 4.
    In principle, it is also possible to fasten the carrier 3 with fastening devices on the side edges or side surfaces of the heating plates 1, 1 'such that it runs in front of the inner surfaces 11, 11' of the heating plates 1, 1 '.
    In the embodiment according to FIGS. 3 a, 3 b and 3 c, the connection units 5, which are connected directly to the fan units 4 by means of fastening units 13, are suspended from the carrier 3 by the carrier 3 with clamping units 18 having terminals 7, which are arranged on the connection units 5 , wherein the fan unit 4 rests on the support plate 15. By means of expansion clamps or bolts 13, the connection units 5 are connected to the fan units 4. If the connection units 5 are made pressure-resistant, insertion of the chain of the fan units 4 onto the support between the heating plates 1, 1 'is also possible in this case.
    Pulling out the chain of fan units 4, wherein the interconnected fan units 4 are moved along a curved path, is made possible by the elastically bendable connection units 5.
    It can be seen that, instead of individual connection units 5 which connect adjacent fan units 4, a continuous connection unit 5 can be provided which carries fan units 4 arranged at predetermined intervals and is connected thereto. Such an embodiment is not shown. It is also possible to attach the fan units 4 to connection units 5.
    The shape and design of the carrier 3 can be varied within wide limits. It is only necessary for the carrier 3 to be arranged in front of the inner surface 11, 11 'of the respective upper part of the respective upper part of the respective upper part of the inner surface 11, 11'.
    Hot plate 1, 1 'can be fixed so that the fan units 4 come to rest between the heating plates 1, 1'.
    As can be seen from FIGS. 4, 5 and 6, profile carriers can be used as carrier 3, for example H-beams, T-beams or C-beams, to which profile beams the connecting units 5 provided with projections 20 and / or recesses correspond are adjusted.
    In Fig. 7, an embodiment of the invention is shown, in which the carrier 3 is fixed by means of a flange 19 to the Konvektorblechen 6 of two oppositely arranged heating plates 1, T. The connection unit 5 with the fan unit 4 is suspended downwards and festgeiegt by means of terminals 7 of a clamping unit 18 on the carrier 3.
    In Fig. 8a, &quot; threading &quot; or the &quot; pull &quot; a chain of fan units 4 in and out of the space between two heating plates 1,1 'shown schematically. It can be seen that during or immediately after the removal of the connecting units 5 or the fan units 4 from the carrier 3, the chain or the connecting units 5 can be subjected to a turn, because the connecting units 5 are made bendable. Thus, as shown in FIG. 9a, for example, a &quot; threading &quot; the chain of fan units 4 in the space between hot plates 1, Γ by the otherwise inaccessible area between two valve sets 10, which are arranged in the region of the lower collecting channel of the heating plates 1, T for connecting the collecting channels of these two heating plates 1, 1 ' ,
    In the embodiments according to FIGS. 8a to 8c and 9a to 9c, no clamping element is provided with which the connecting units 5 are fastened to the carrier 3, but the carrier 3 carries the connecting elements 5 and the fan units 4.
    As can be seen from FIGS. 8b and 8c or, 9b and 9c, the carrier 3 is formed by two angle profiles or C-profiles arranged opposite one another, which are fastened to the heating plates 1, 1 '. On the profiles, the fan units 4 and / or the connection units 5 are on or pushed or placed and can be introduced by retraction or disassembled by pulling.
    The carriers 3 can be detachably fixed to the heating plates 1, 1 'or to the convector plates 6 in order to be able to exchange the carriers if need be, in particular if the connection units 5 or the fan units 4 are to be replaced by differently dimensioned units.
    It is important that through the space between the heating plates 1, T, the air can circulate largely unhindered, even in the event that the
    Fan units 4 are not in operation to achieve a good heating performance. Attention is thus paid to the fact that the connecting elements 5 do not obstruct the air movement as far as possible. It is particularly important and advantageous that a mounting and dismounting of the fan units 4 and the connecting units 5 is also possible with hydraulically connected to the fluid network radiators and is also possible if these radiators mounted in a radiator with relatively small lateral distance to the wall were.
    The mounting of the carrier 3 can be done at any point of the heating plates 1, T. Advantageously, however, the carriers are arranged in the vicinity of or below the convector plates 6.
    Between the fan units 4, a distance is maintained, which specifies an optimum efficiency for the fan units 4.
    A radiator with only one heating plate, in front of whose preferably wall-side surface a support 3 extends, is not shown in the drawings.
