気集熱器を提供することを目的とする。Detailed Description of the Invention (Field of Industrial Application) Generally used silicon-based solar cells have a low power generation efficiency of about 20% at most. In some cases, the conversion efficiency is only as low as 1.9%, and most of the solar energy is discarded into the atmosphere as thermal energy. As a method to actively collect this heat without wasting it and use it for hot water supply and space heating, solar cells with plate-shaped substrates (hereinafter referred to as ``solar panels'') are used to collect solar heat in a collector. There is a hybrid system that uses the heat as a part of the system to generate electricity and collect heat at the same time. Conventionally, in order to prevent the reduction in solar cell conversion efficiency due to high temperatures, there was a method of cooling the lower part of the solar cell with air, etc., so this cooling air could be used as a heat medium for heat collection and used for space heating or hot water supply. You can easily consider the hybrid method to use. Conventionally, systems that use solar panels without covers and cool the bottom side of the solar panels have used opaque solar panels. When this type of heat collector is used as a hybrid heat collector, the heat collection efficiency becomes extremely poor when the temperature of the air flowing inside the collector becomes high. Additionally, if a solar panel is installed at the bottom of the front cover and air is allowed to flow between the front cover and the solar panel, the solar battery may become hot or dust may accumulate on the solar panel, causing the solar battery to deteriorate. The disadvantages are that the power supply efficiency decreases and the price increases. An object of the present invention is to provide a hybrid air collector that cools solar cells with air, reduces the reduction in conversion efficiency, and is inexpensive and has relatively good heat collection efficiency.

The present invention provides a heat collector characterized in that the surface cover is a solar cell panel that is partially transparent like a striped object, and a heat collector is provided at the bottom of the surface cover. In the case of a roof-integrated heat collector, the roof is a heat collecting plate such as a metal plate, and a partially transparent solar panel is installed on top of it.

，太陽電池の負荷の例である。A glass substrate solar panel has solar cells arranged in a net shape, and the solar cells are distributed almost evenly over the entire surface of the substrate. The only part of the solar cell panel 1 other than the net-like or band-like solar cells itself is the transparent glass of the substrate. The heat collecting plate is a metal plate painted black, and the heat insulating material 3 is a metal plate painted black, and the heat insulating material 3 is a metal plate painted black.
, the heat insulating material 3 is integrated with a frame 4, and air 5 is allowed to flow through the interior through forced or natural circulation. 6 is a light bulb, which is an example of a solar cell load.

低く保つことができる。When the collector receives solar radiation, a portion of the solar energy is converted into electricity by solar cells. Of the light emitted by solar cells, what is not converted into electricity becomes thermal energy.
Thermal media in the atmosphere or in the collector in contact with the solar panels (
air) is released into 5. In addition, some of the sunlight that hits the transparent parts other than the solar cells is absorbed by the solar cell panel 1.
The light is absorbed as thermal energy by the light, passes through the rest, and is received by the heat collecting plate 2. Thermal energy absorbed by the solar panel 1 is released to the atmosphere and the heat medium (air) 5 in the collector. Since the solar cell panel 1 serves as a surface cover of a heat collector and is in contact with the atmosphere, the temperature of the solar cell panel can be kept relatively low.

選ぶようにすればよい。In addition, since sunlight is collected on two surfaces, the surface cover 1 and the heat collection plate 2, and then the heat is transferred to the heat medium 5, the heat collection efficiency is lower than when an opaque solar panel is used as the surface cover. growing. Increasing the area ratio of the solar cell part of the solar panel 1 increases the amount of power generated, but if the temperature of the heat medium is high, more heat escapes from the surface to the atmosphere, making it unsuitable for high-temperature heat collection. . therefore,
The area ratio of the solar cell portion may be appropriately selected depending on the heat collection temperature level.
