    Absorbance energy and apparatus for converting radiant energy
    In usable energy
    The invention relates to a device for converting radiant energy into usable energy, in particular into electrical and thermal energy, comprising an absorption arrangement for absorbing and converting the radiant energy, the absorption arrangement having a front side and a rear side, the front side being arranged for alignment in the direction of radiation squareness , and wherein the absorption arrangement forms a heat source when irradiated by the Strahlungsenergle the radiation source, the heat is transferred from a heat exchanger to a heat transfer medium. The invention particularly relates to a device which is ausgebildef as a solar co-planar, Solarpaneei unüloder hybrid collector.
    For the conversion of radiant energy, in particular solar radiation, different devices are known and published.
    For example, solar panels are known in which solar cells, in particular photovoltaic cells, are provided, these solar cells convert the light impinging on them directly into electrical energy. Due to the solar radiation, the solar cells heat up in practice, which reduces the efficiency of the solar cells.
    From this Gaind solar panels are known in which the solar cells are cooled. This technology is particularly effective when the heat dissipated to cool the solar cells is called heat. For example, for custom heat In a household, use finds.
    According to the prior art, to transfer the heat of the solar cells to a heat transfer medium, metal lines are glued directly or via connecting plates to the rear side of the solar cells or to the rear side of the solar modules. By bonding with a thermally conductive adhesive, a heat transfer from the solar modules is effected on the lines according to the prior art.
    In practice, however, it has been found that it comes with a longer service life of the Soiarpaneele to a detachment of the cables from the solar modules.
    On the one hand, the adhesives used become brittle after some time - on the other hand, due to different thermal expansion coefficients of the lines and the solar modules to tensions, which then leads to a detachment of the components. As a result, there is an air gap between the lines and the solar module, whereby the heat transfer is greatly reduced.
    From a direct investment of thermally conductive platelets on the solar modules without thermal transfer pastes or hot glue is omitted according to a prejudice in the art. Due to the specification of low production costs, the shape tolerances of the individual components are relatively large, which means that between two inaccurately manufactured surfaces often only comes to a point or Unianberührung whereby the heat transfer is reduced.
    Thus, there is a conflict of objectives between ~ permanently consistent heat transfer between Soiarmodui and heat transfer medium. ~ high or efficient heat transfer between Soiarmodui and heat transfer medium, - and favorable or marketable manufacturing costs of such devices, object of the invention is now, in particular to solve this conflict of goals.

    The device according to the invention preferably comprises an absorption arrangement and a heat exchanger.
    The absorption arrangement is designed to convert the radiation energy of the radiation source, for example the solar radiation of the sun, into usable energy. This transformation happens in particular to two different forms of energy. On the one hand, solar cells, in particular via solar cells assembled to form solar modules, can be used to convert the radiant energy into electrical energy. On the other hand, the resulting heat and that radiation component of the radiation source, which is not converted by the solar cells, can be converted into thermal energy. This heat energy is preferably transferred to a Wämneträgermedium. The heat transfer medium is passed through lines that open in all embodiments, for example in a heating system of a building or connected to such a heating system. For example, the heat transfer medium via heat exchangers, the heat transferred to a buffer memory or to another heat transfer medium.
    Due to the configuration according to the invention, on the one hand, the resulting heat is used and transmitted in an energy-efficient manner. In addition, the efficiency of the solar cells is also improved
    The heat exchanger comprises at least a first line through which the heat transfer medium flows in the control mode. With this line a Wärmeieitanordnung is connected thermally conductive. The Wärmeieitanordnung includes heat consumers, which rest against Wärmeieitsteiien at the heat source. The heat consumers may be formed, for example, finger-shaped or strip-shaped. According to a preferred embodiment, these fingers or strips have different lengths or protrude these fingers or strips at different distances from the first line. This has the effect that the Wärmeieitsteiien are spread along a heat transfer area of the device at a plurality of sites areal or two-dimensionally distributed. In particular, it is assumed that a strip-shaped heat transfer area is formed along the first line. Along this heat transfer area the Wärmeieitsteiien are irregular or regularly distributed. The distribution is not only along the length of the line given, but also in the transverse direction, so at different distances from the line Wärmeieitsteiien are formed. By this arrangement, an efficient heat transfer is effected. In the case of purely strip-like (linear) juxtaposition of heat elements, the density of heat conductors is higher in certain areas than in other areas. Since the heat transfer is best, especially at high temperature gradients, ie at high temperature efficiency, the surface distribution also causes a planar reduction and thereby a uniform reduction of the temperature difference. Thus, in the context of this invention, a two-dimensional distribution of heat fractions along a heat transfer area is defined as areally distributed. The heat transfer area is preferably a surface area on the rear side of the heat source,
    Preferably, a plurality of first lines are provided side by side, which open into a second line. Preferably, this arrangement is configured such that a sheet-like heat exchanger is formed. The sheet-like heat exchanger comprises a plurality of heat consumers whose heat elements lie substantially in one surface and / or in one plane. In the case of even heat sources, a planar heat exchanger is advantageous. In the case of slightly curved or curved heat sources, a surface-shaped heat exchanger following this form may be advantageous.
    The heat conduction arrangement preferably comprises heat receivers. These heat receivers and in particular the heat conduction arrangement can be formed, for example, of a heat-conducting material, preferably of metal, an aluminum alloy and / or a copper alloy. The first conduit and / or the second conduit can also be made of metal, an aluminum alloy and be formed or a copper alloy. Preferably, the Wärmeieitanordnung is formed of a material that is welded or soldered to the first line. For example, to provide a heat exchanger according to the invention, a conduit may be provided which is substantially straight. Further, the conduit may be or may be provided at predetermined locations, particularly remote from the lateral ends of the conduit, with a U-shaped offset the main direction of extension of the first line preferably is substantially linear. The offset is used, for example, to absorb longitudinal stresses, for example by manufacturing tolerances or by expansion of walls. Optionally, however, it is also possible to dispense with an offset of the line. In a further step, the heat dissipation arrangement is formed from a flat strip, in particular from a flat metal strip individual elements are punched out or cut away from the roofed Bend so that several finger-shaped heat consumers are formed. Preferably, the semifinished product for producing the Wärmeieitanordnung a flat metal strip, in particular a copper strip or an aluminum strip, the thickness of this band and thus the heat consumer, for example, between 0.1 and 1 mm, optionally up to 3 mm.
    In a further step, the Wärmeieitanordnung can be connected to the first line '. This connection is preferably stoffschlüsslg, in particular by welding. In this case, either one or both throats between the Wärmeieitanordnung and the first line can be provided with a fillet weld. Optionally, by ultrasonic welding through the front of the Wärmeieitanordnung, ie by that side which faces away from the first line, a welding of the back of the Wärmeieitanordnung be effected with the line. The welds can be punctiform, sections or continuous.
    The laterally projecting ends of the heat conduction arrangement or of the heat receivers preferably stand at different distances from the first conduit, in order to achieve in particular the effect according to the invention.
    To improve the efficiency of the overall system, the device comprises a special absorption arrangement. This absorption arrangement comprises a solar arrangement. in which preferably several solar cells are combined to form a solar module. The solar module is preferably flat and covered along its surface extension on one side or on both sides by a respective soy protective layer. Preferably, the solar cells of the solar array are embedded in the soy protective layer or in the solar protective layers. The solar protective layer is preferably formed as EVA-Folle, ethylene vinyl acetate film or ethylene vinyl acetate / Eva layer. The soiar protection layer is preferably designed to protect the solar cells against environmental influences.
    More preferably, the at least one soy protective layer is formed so as to be radiation-permeable for at least a part of the radiation, so that, for example, infrared radiation can be used efficiently to utilize the heat. For this purpose, in particular, an absorption layer is provided which allows efficient conversion of the infrared radiation and / or the waste heat of the solar array. In all embodiments, the absorption layer can be, for example, a layer which absorbs the solar radiation and which is preferably laminated with a metal rim, for example made of copper, aluminum or another metal. The absorbed solar radiation can thereby flow to the heat consumers. The absorbed solar radiation comprises, in particular, infrared radiation which is converted into heat on the absorption layer and, moreover, the thermal energy which occurs when solar energy is converted into electricity in the PV cells.
    The absorption layer may be, for example, a dark layer, such as a black plastic film. Optionally, the absorption layer is part of the soy protective layer. Optionally, facing away from the Strahlungsqueile

    To further improve the efficiency, a heat layer may be provided at the back of the absorption assembly. This heat conductor layer may be, for example, a metal coating of the absorption layer.
    Preferably, the heat takers are in direct contact with the heat conductor layer in the regular operation. In all embodiments, the absorptive layers and / or the thermal layer of ice itself may also be omitted. Optionally, the heat consumers are directly attached to the solar array, the Absorpfionssehieht or on the Wärmeieitschicht.
    The device comprises according to a preferred embodiment, a housing in which the Absorptiensanordnung can be provided. The housing preferably comprises one or two openings for the supply and discharge of the Wärmeträgarmediums. Preferably, the housing also includes an opening for passing an electrical cable to dissipate the electrical energy.
    For protection and to cover the device, the device preferably comprises a covering layer, which can be designed in particular as a plastic plate, glass plate or as a double-glazed pane. With this cover layer, the housing is preferably closed. The cover layer is preferably radiation-permeable, so that the radiation of the radiation source can hit the absorptive arrangement provided behind the abdeok layer unhindered.
