  • the invention relates to a solar collector for the direct conversion of thermal energy supplied by solar radiation into electrical energy.
  • the object of the invention is to provide a solar collector for the direct conversion of thermal energy supplied by solar radiation into electrical energy, which combines the advantage of a solar cell with the comparatively cheap and robust construction of a solar collector.
  • thermopile consisting of any number of thermocouples connected in series, one contact point of which can be heated by the absorbed solar radiation and the other contact points of which can be cooled by a circulating fluid, such as water in particular.
  • the invention thus uses the known phenomenon of thermoelectricity to generate electrical energy, with which it generates an electrical voltage generated by any number of thermocouples connected directly in the absorption region of the solar radiation using the heat generated, to which, for example, a battery for charging and further supply can be connected by consumers.
  • such a solar collector is therefore a plate collector formed, which can expediently occur in that the thermopile consists of a plurality of surface-covering pairs of short wires arranged side by side from the two substances to be combined to form a thermocouple, which alternately at the upper and lower ends to form inner and outer contact points with each other are connected, the inner contact points being embedded in a non-conductor absorbing the solar radiation, while the outer contact points can be cooled by the cooling fluid.
  • the non-conductor absorbing the solar radiation is a layer of quartz sand solidified by a binder.
  • the wires can sealingly pass through a plate made of non-conductive material, which forms the top wall of a flat chamber through which fluid such as water flows.
  • This plate is preferably made of acrylic glass, into which the wires are gauged leaving the outer contact points free.
  • batteries of any size can be created with such a plate collector, which can be connected to a common cooling water circuit. Since the solar radiation is not always available due to the time of day and weather, it is advisable to use such a solar collector system to supply an electric battery such as an accumulator to which the consumers to be supplied are connected.
  • the solar collector according to the invention offers a particular advantage for such systems, which can be exploited by a device for storing the heat energy dissipated by the cooling water from the solar collectors when the sun is shining, the stored heat energy in the absence of sun radiation cooling the cooling water while heating the same can be supplied again, while at the same time the connection of the battery to the collectors can be reversed.
  • thermocouples In this way, it is possible to convert the thermal energy dissipated by the cooling fluid, such as water, which is not initially used to convert it into electrical energy, in times of no solar radiation using the same thermocouples and thus the yield of electrical energy from the Increase sun exposure significantly.
  • the cooling fluid such as water
  • the storage device consists of a heat exchanger through which cooling water flows on the primary side, the secondary side of which is connected to a heat store via a reversible heat pump.
  • the heat accumulator is charged by the heat pump, while at the same time the cooling fluid, such as water, is cooled to the temperature required to keep the external contact points of the thermocouples cold.
  • thermocouples are now significantly warmer than the internal contact points, which have cooled down considerably at night, so that a voltage occurs at the thermopile in the opposite direction, which makes it necessary to reverse the polarity of the connected battery.
  • the solar collector designated in its entirety by 10, is a plate-shaped Eauelement, for example 10 x 10 cm in size, which will generally be arranged with such an inclination towards the midday position of the sun that the annual and daily average is as steep as possible on the collector surface hits.
  • the solar collector 10 has a layer 14 of, for example, quartz cement expediently covered by a glass plate 12, in which the upper or inner contact points 16 of a large number of thermocouples 18 are embedded.
  • Each thermocouple 18 consists of two short wires 20, 22 of different metals or alloys, which are soldered or welded together to form the upper contact points 16.
  • the thermocouples 18 are with the formation of outer or lower contact points 24 between a wire of the one substance and a wire of the other substance connected in series to a so-called thermopile.
  • thermocouples can be connected in series on the area of 1 ⁇ x 10 cm 3300 considered, which results in an open circuit voltage of 6.6 volts when using copper and constantan for the two wires 20, 22 at 50 ° C.
  • thermocouples 18 are cast with the lower contact points 24 into an acrylic glass plate 26, which forms the top wall of a flat chamber 28 through which a cooling fluid, such as water, flows.
  • a cooling fluid such as water
  • a pump 30 conveys the cooling fluid in a closed circuit through the chamber 28 and the primary side of a heat exchanger 32, which is thermally connected on the secondary side via a reversible heat pump 34 to a heat accumulator 36 of any design.
  • thermopile formed by the series connection of the termocouples 18 is connected via connecting wires 38, 40 and a pole reversing switch 42 to a battery 44, to the terminals 46, 48 of which any consumer can be connected.
  • the solar radiation impinging on the solar collector 10 heats the quartz cement layer 14 and thus the inner contact points 16 of the thermocouples, while at the same time their outer or lower contact points 24 are kept at a comparatively low temperature by circulation of the cooling fluid by the pump 30.
  • the temperature difference between the inner contact points 16 and the outer contact points 24 causes the formation a voltage in the thermopile and thus a current flow through the battery 44 with which it is charged.
  • thermocouples The heat penetrating from the quartz cement layer 14 through the acrylic glass plate 26 as well as the heat generated by the current flow in the thermocouples will try to heat the lower or outer contact points 24 of the thermocouples as well. This heat is continuously removed from the cooling fluid and supplied to the heat accumulator 36 with the aid of the heat exchanger 32 and the heat pump 34.
  • the solar collector 10 can still be used to generate electricity by reversing the heat pump 34 and thus supplying heat from the heat accumulator 36 and the heat exchanger 32 to the cooling water.
  • the pump 30 now presses the warm cooling water through the chamber 28 of the solar collector and heats the lower or outer contact points 24 of the thermocouples, while the upper or inner contact points 16 are cooled by the ambient air, especially at night. This creates an opposite voltage on the thermocouples 18, which is reversed with the aid of the pole changer 42, so that the battery 44 can be charged further under these circumstances.
  • the collectors of the system can be provided in a known manner with concentrators, in particular mirrors, such as, for example, in the known solar cookers, in order to increase the amount of radiation incident on them and thus to increase their temperature and, consequently, the voltage and power generated.

Abstract

Le collecteur solaire permettant la conversion directe de l'energie thermique recue en energie electrique combine les avantages d'une cellule solaire avec ceux d'un collecteur solaire classique dont la construction est robuste et economique. Il comprend une colonne thermique consistant en un nombre quelconque de thermo-elements (18) connectes en serie. L'un des points de contact (16) de chaque thermo-elements est chauffe par le rayonnement solaire absorbe tandis que l'autre (24) est refroidi par la circulation d'un fluide (28), de preference, de l'eau. Le collecteur peut etre un collecteur a plaques dans lequel la colonne thermique est avantageusement composee d'une pluralite de paires juxtaposees de courts fils (20, 22) en materiaux appropries.
