    Heat exchanger and device for converting Sfrahlisngsenergle into usable energy oils 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, wherein the absorption arrangement has a front and a back , wherein the front side is set up to align with the radiation source. and wherein the absorption arrangement upon irradiation by the radiation energy of the radiation source forms a heat source whose heat is transferred from a heat exchanger to a heat transfer medium. In particular, the invention relates to a device which is designed as a solar collector, solar panel and / or 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 that hits 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.
    For this reason, soiar panels are known in which the solar cells are cooled. This technology is particularly effective if the heat dissipated to cool the solar cells is used as useful heat, for example for domestic heat in a household.
    According to the prior art, for transferring 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 emerged that with longer service lives of the solar panels, detachment of the cables from the solar modules takes place.
    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 pipes 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 grease or Wärmelaiikleöer is disregarded 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 line contact, whereby the heat transfer is reduced,
    Thus, there is a conflict of objectives between - permanently consistent heat transfer between Soiarmodul and heat transfer medium, - high or efficient heat transfer between Soiarmodul and heat transfer medium, - and favorable or marketable manufacturing costs of such devices. The object of the invention is now to solve in particular this Zieikonflikt.

    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 solar cells assembled to form solar modules, can convert the radiation energy into electrical energy. On the other hand, the resulting heat and the radiation component of the sirloin, which is not converted by the solar cells, can be converted into heat energy. This heat energy is preferably transferred to a heat transfer medium. 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 exchanger, 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 during normal operation. With this line a Wärmaleitanordnung is thermally conductively connected. The heat conduction assembly includes heat receivers attached to heat sources at the heat source. The heat consumers may be finger-shaped or strip-shaped, for example. According to a preferred embodiment, these fingers or quarries are different catch hzw. protrude these fingers or stripes differently far from the first line. This has the effect that the Wärmieitstelien are distributed along a heat transfer area of the device at a plurality of sites areal or two-dimensionally. In particular, it is assumed that a strip-shaped heat transfer area is formed along the first line. Along this heat transfer area, the heat elements are distributed irregularly or regularly.

With purely linear (linear) juxtaposition of Wärmieitstelien the density of Wärmieitstelien 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 flat 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 elements along a heat transfer region is distributed over a wide area Are defined. The heat transfer area is preferably a surface area on the rear side of the heat source.

Subsequently, the line can be provided at predetermined locations, in particular away from the lateral ends of the conduit with a U-shaped bend or be. Nevertheless, by definition, the main direction of extension of the first line is preferably substantially linear.

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. Ose welds can be punctiform, sectional or continuous.
    The laterally projecting ends of the heat-dissipating arrangement or of the heat-receivers preferably stand at different distances from the first line, in order in particular to achieve the effect according to the invention.

    More preferably, the at least one solar protection layer is radiation permeable for at least a portion of the radiation, so that, for example, infrared radiation can be used efficiently for the use of the warning. For this purpose, an absorption layer is also provided which enables efficient conversion of the infrared radiation and / or the waste heat of the solar arrangement may be in all embodiments, for example, a layer that absorbs the solar radiation and which is preferably laminated with a Metallfoila, such as copper, aluminum or other metal. This allows the absorbed solar radiation to 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 heat loss which occurs during the conversion of solar energy into electricity in the PV cells.
