実用化されている。Solar heat collectors usually collect heat by passing a heat-absorbing medium such as water or air inside a vessel or tube in which a cape heat-collecting material is placed.
A type that uses a heat-absorbing medium to absorb solar heat collected by a heat-collecting material has been put into practical use.

ト化、耐久性。The heat collecting materials for these heat collectors need to maintain high heat collecting performance and durability, so they are made of expensive materials such as copper, aluminum, and stainless steel, and are made of special absorbing metal materials such as pressed and welded. It required machining and was expensive. These heat collecting materials corrode from work-hardened parts and welded parts.
The problem was that it caused damage due to cracking force, and because the shape was fixed, it was easy to cause accidents due to freezing in winter. In addition, there are heat collectors using air as a V heat absorbing medium and using butyl rubber cape material as the heat absorbing material, but there are problems such as low heat resistance and easy KV shape at high temperatures. In this way, conventional heat collecting materials are low cost and durable.
収態性能をいずれも満足するものは見出されていない。No material has been found that satisfies all of the storage properties.

状などとなし使用するので、従来の集熱材のごとく様々
な加工を必要とせず、低コスト化が達成できる。Carbon fiber is black and has an extremely large surface area per unit volume. Therefore, the absorption rate of irradiated solar heat is high, and the emissivity is also high, and the heat exchange rate with the water flowing in contact with the heat absorbing medium of the air space is excellent, and the heat collection efficiency of the heat collector can be improved. In addition, carbon fiber is extremely stable thermally and chemically, and when used, there are few hardened and fixed parts, so there is no risk of damage due to thermal deformation, freeze-thaw, corrosion, etc., and the durability of the collector is improved. improves. Furthermore, since carbon fibers can be used in the form of tow, chips, web, non-woven fabric, fabric, sheet, etc., they do not require various processing unlike conventional heat collecting materials, resulting in lower costs. It can be achieved.
炭素繊維は、一般市販されているものが使用できる。し

た高弾性率炭素繊維は高コストであるので、コストの面
では好ましくない。Commercially available carbon fibers can be used. However, for example, high-modulus carbon fibers made by firing acrylonitrile fibers at a high rate are expensive, so they are not preferred from a cost standpoint.

Heat collectors are constructed by installing web, nonwoven fabric, woven fabric, sheet, and other forms. When processing carbon fibers into nonwoven fabrics, webs, sheets, etc., it is necessary to use needle punching, intertwine the fibers by papermaking, etc., or bind delicate fibers together using a binder, depending on LIK. is taken.
