Definitions
- the invention relates to a solar system with a Clarkol ⁇ lecturer and a photovoltaic or thermoelectric converter, which is aligned with respect to the solar collector such that the solar radiation is concentrated on the converter.
- a solar system of the type described is example ⁇ way according to WO 2011/028742 AI known.
- a solar panel in the form of a parabolic trough is used, wherein a photo- voltaic converter (a solar cell, for example) may be angeord ⁇ net in the focal axis of the parabolic trough.
- a solar system is also referred to as a so- ⁇ -called fotovoltaic concentrating system (CPV).
- CPV fotovoltaic concentrating system
- Such arrangements are used to increase the force acting on the wall 1er amount of solar radiation to obtain a given cost components as large as possible Ausbeu ⁇ te of electrical energy.
- the object of the invention is to provide a solar system with a solar collector and a photovoltaic or thermoelectric converter (hereinafter referred to as converter), in which comparatively much solar radiation can be concentrated on the converter.
- converter photovoltaic or thermoelectric converter
- thermosyphon circuit for cooling the converter a thermosyphon circuit is provided with an evaporator part and a condenser part, wherein the evaporator part is thermally conductively connected to the transducer.
- a thermally conductive connection is meant a connection between these components which dissipates the heat comparatively well. The connection itself should therefore take so good Minim ⁇ least the heat, as the material of the transducer or the material of the evaporator part forming thermosiphon circulation - depending on which conducts heat worse of the two structural units.
- si ⁇ cher in this manner is advantageous si ⁇ cherines that no thermal insulation is effected by the connection between the thermal ⁇ siphon circuit and the converter, but that this compound is at least neutral effect in terms of heat transfer between the transducer and the thermosyphon circulation.
- the compound Zvi ⁇ rule converter and the evaporator part of the thermosyphon circuit assembly can be realized technically, for example, a contact pressure.
- the evaporator part is connected to the converter via a solder connection or an adhesive connection. In this way, advantageously, the heat transfer between the evaporator part and the converter can be optimized by the material connecting these units rests with the largest possible surface on the ⁇ adjacent parts.
- a solder joint improves the heat transfer advantageous in that relatively good conductive metallic materials can be used for the Ver ⁇ binding between the units.
- the transducer may be metallically coated on the side facing the evaporator part.
- the thermal conductivity ⁇ ness of the connection between the evaporator portion and the converter is greater than 200 W / (m K). This is a value for the thermal conductivity which is typical for metallic materials.
- copper has a thermal conductivity of 403 W / (m K) (ie watts per meter times Kelvin).
- the heat transfer can be done advantageously with a low thermal resistance.
- the evaporator part is protected by a sun visor from direct sunlight. This sun visor may advantageously have a surface reflecting at least parts of the sunray radiation.
- the cooling power provided by the evaporator part is available alone or at least mainly for cooling the converter. If the sun visor itself reflects at least parts of the sunray , this has the additional advantage that the sun visor heats up less. As a result, it is possible to prevent a thermal shock from the sun visor
- a particularly advantageous embodiment of the invention is obtained when the solar collector is designed as a parabolic trough and the evaporator part is tubular and extends from one end of the parabolic trough to the other end. Just as the transducer, which is arranged in the focal axis of the parabolic trough, the evaporator part then runs over the entire length of the parabolic trough and can ensure cooling of the transducer over its entire length.
- thermosiphon circulation ensures the evaporator part must be on mountain directed and aligned parabolic troughs with their longitudinal axis at an angle to the horizontal. Only in this way can the evaporating working medium in the evaporator section of the thermosiphon circuit flow to the upper end of the evaporator section where it releases the heat in a condenser section again. This process is driven by gravity and is therefore dependent on the said orientation of the evaporator part.
- the evaporator part in his Cross section is adapted to the contour of the transducer.
- this may have a flattened portion, on which the preferably flat-shaped transducer elements can be ⁇ solidifies.
- the already mentioned solder joint can advantageously be used with a uniformly thick joint gap. The available surface for a heat transfer is thus advantageously formed maximum.
- the capacitor part of the thermosyphone circuit is protected by a cover from the solar radiation.
- the working medium of the thermosyphon circulation should condense, i. H. Give off heat. Therefore, an additional introduction of heat in this area should be avoided.
- the sun visor advantageously reduces the introduction of solar energy into the condenser part.
- the capacity of the storage for the cooling medium is dimensioned so that the cooling requirement during the day can be satisfied by taking advantage of the cooling at night.
- the fact is taken into account that solar systems are only during the day in operation when the sunlight is converted. At night there is no light for Availability checked ⁇ supply, so that the converter does not require refrigeration.
- Au ⁇ ßerdem cools the vicinity of the solar system, so the thermosiphon circuit can deliver more heat to the environment than during the day. If sufficient cooling medium is kept in the thermosiphon circuit, it can be stored in a memory. During the day, this storage tank is warmed up by the fact that the cooling medium can deliver less heat to the environment and absorb more heat from the transducers. Therefore, the cooling medium will heat up throughout the day. At night, this heat can be given off again.
- the cooling capacity of the thermosiphon circuit can be advantageously increased in this way.
- thermosyphon circuit Another advantageous measure to increasemékapa ⁇ capacity of the thermosyphon circuit is that the con- can be connected downstream of an aftercooler. This allows a further cooling of the cooling medium after Verflüs ⁇ sist done in the condenser part, before this is supplied to the evaporator part again.
- FIG. 1 shows a cross section through an exemplary embodiment of the solar installation according to the invention, in which a parabolic trough and the evaporator section of the thermosyphon circuit can be seen
- Figure 2 shows the cross section through an evaporator part of
- Thermosyphone circuit with soldered transducers according to another embodiment of the inventions ⁇ inventive solar system and
- FIG. 3 is a side view, partially in section, of another embodiment of the solar system according to the invention.
- a solar collector 11 for the solar system is shown in section.
- the focal axis of the solar panel designed as a parabolic trough is perpendicular to the dargestell th plane.
- transducer 12 are arranged ⁇ , which is indicated by means of exemplary drawn sun rays 13 that the solar collector 11 bundles the sunlight on the transducer.
- the transducers are photovoltaic elements (solar cells). These heat up due to the irradiation of the sunlight and are represented by the evaporator part 14 of a thermosyphon circuit 15 (see FIG Also Figure 3) cooled.
- the evaporator part 14 is further protected on the side facing away from the solar collector 11 side with a sun visor 16 from direct sunlight. Therefore, this is mainly heated by a heat transfer of the heat generated in the transducers 12, so that the provided in the thermosyphone circuit and not closer Darge ⁇ set working medium can evaporate.
- the sun visor 16 is provided with a surface 19 which strongly reflects the sun rays 13 so that the sun visor itself warms up as little as possible and therefore can supply as little heat as possible to the evaporator part 14 by convection.
- the evaporator part has flattened preparation ⁇ surface 20 in cross-section, so that the flat transducers may be introduced ⁇ ge 12 over its entire width with the evaporator portion in contact.
- FIG. 2 shows a different profile of the evaporator part 14 as a section.
- This is a circular We ⁇ sentlichen cross-section which, however, also has two flats 20 at which the converter 12 with a solder layer 21 as a thermally well conducting heat ⁇ transition layer having a thermal conductivity greater than 200 W / (m K) can be attached.
- a soldering of the converter 12 is possible with the metallic evaporator part 14, the transducers 12 are provided at their part of the evaporator 14 supplied ⁇ facing side with a metallization 22nd
- the metallization layer can be applied to the rear side of the transducers, for example by means of sputtering.
- the evaporator part can be made for example of a copper tube.
- Another possibility is to use an extruded aluminum profile. 3 shows the entire thermosyphon circuit is familiar to ⁇ he 15th In the evaporator part 14, the working medium evaporates and rises. Therefore, the solar collector 11 must also be directed with its focal axis upwards and not be mounted with waa ⁇ fair focal axis.
- a supply line 25 and a discharge line 26 in the immediate vicinity of the evaporator part 14 must then be elastically formed at ⁇ example by hoses.
- thermosyphon circuit 15 The evaporating in the evaporator part 14, working medium rises upwardly and passes through a capacitor portion 27 where the Ar ⁇ beitsmedium heat to cooling fins 28 and thereby condensed. It is then fed to a memory 29.
- the cooling medium can be pumped during the night with a circulation pump 30 in the liquid state through the thermosyphon circuit and releases the heat stored during the day to the cooler night air.
- an aftercooler 31 work with cooling fins 28, the capacitor part 27 and the evaporator section 14 each as a cooler, since these areas of the thermosiphon circuit are executed with good thermal conductivity and allow a heat ⁇ discharge of the working medium.
- lying outside of the solar collector 11 of the thermosyphon circuit 15 is shaded with a cover 32.
