る太陽熱集熱器に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a solar heat collector that collects solar heat and supplies it for hot water supply or space heating.
従来例の17〜成とその問題点

が必要となる。17. Conventional Examples and Their Problems In general, solar collectors convert solar energy into thermal energy using a heat collecting plate, transmit it to a heat medium, and are used for hot water supply, space heating, etc. By the way, a characteristic required of solar heat collectors is to efficiently collect heat. First, it is necessary to efficiently absorb incident energy and prevent heat dissipation as much as possible.
熱放散には、放射・対流・伝導の三形態がある。There are three forms of heat dissipation: radiation, convection, and conduction.
まず放射であるが知られているように、物質はその絶対

1■する方法として、太陽光に対する吸収率は大きいが
、赤外放射の放射率の小さい選択吸収膜を集熱板表面に
塗布することが知られている。First, regarding radiation, as is known, substances emit thermal radiation (infrared radiation) to their surroundings depending on their absolute temperature. In other words, the heat collector plate, which has become hot due to the incidence of solar energy, radiates a large amount of heat to its surroundings. As a method for preventing this, it is known to apply a selective absorption film that has a high absorption rate for sunlight but a low emissivity for infrared radiation on the surface of the heat collecting plate.

るものが知られている。Moreover, one form of the ability of heat dissipation from the heat collecting plate is due to air convection existing above the heat collecting plate. In order to prevent this, a second cover made of glass, planutic, etc. is provided with an air layer sandwiched between the heat collecting plate and the second cover.
It is known that a second cover blocks the convective air generated between the cup and the heat collecting plate, and uses the air layer as a heat insulating layer.
最後に伝導であるが、これを防止するために太陽熱集熱
器内底部には、断熱拐が使Ilコされている。Finally, to prevent conduction, a heat insulating layer is used at the inner bottom of the solar collector.

必要があった。In conventional solar heat collectors that have increased the actual heat efficiency in this way, if water is not passed during construction or when not in use, the heat collection plates will become abnormally damp due to solar radiation. 3
The temperature reached over 00℃. And (4), in order to cope with the abnormal temperature of the heating plate, it was necessary to improve the heat resistance of the coating film or one-way selective absorption film on the heating plate. At the junction of the heat collecting plate and the heat collecting pipe, j1
Since the solder alloy α of ordinary Pb-8n7T' melts, it is necessary to use a special soft solder, and avoid thermal expansion with the upper and lower headers that connect a large number of heat collecting pipes. Therefore, it was necessary to adopt an expansion-absorbing structure that includes a bellows section.
