Abstract

PURPOSE:To effectively utilize light reflected to the back side of heat collecting fins by providing a selective absorption film even on the back surfaces of heat collecting fins. CONSTITUTION:A copper heat collecting pipe 2 provided with aluminum heat collecting fins 3 is inserted into a transparent and glass outer pipe, and the interior of the outer pipe 1 is kept in vacuum and the selective absorption film 4 and 6 are provided on the front surface and back surface of the outer pipe 1. While the solar heat is mainly absorbed to the front side of the heat collecting fins 3 within the vacuum pipes, a part 12 of the solar heat is reflected on an adjacent outer pipe 10, and reaches the back side of the heat collecting fin 3.

反射特性を持っている。Structure of the conventional example and its problems In the conventional vacuum tube solar collector, as shown in FIG. 1, a heat collecting tube 2 is inserted into a transparent outer tube 1,
Heat collecting fins 3 were disposed in the outer tube 1, the inside of the outer tube 1 was evacuated, and a selective absorption film 4 was provided only on the front side of the heat collecting fins 30. That is, in order to collect heat with the heat collection fins 3, raise the temperature of the heat medium 5 in the heat collection tube 2, and absorb a large amount of the heat medium, it is preferable to use black for absorption. However, with ordinary black paint, the absorber absorbs sunlight (short wavelength energy) well and the temperature of the absorber increases, but the heat dissipated from the absorber (long wavelength energy) also increases. The selective absorption film 4 has spectral reflection characteristics that maximize sunlight absorption and reduce heat radiation.

陽光の反射エネルギーを有効活用できなかった。In a conventional vacuum tube type solar water heater, the four selective absorption membranes are provided only on the front side of the heat collecting fins 3. Therefore, the reflected energy of sunlight from the periphery of the transparent outer tube 1 to the back side of the heat collecting fins 3 could not be effectively utilized.

発明の目的 本発明は、この点に着目し、集熱フィン裏側への反射光

In other words, how many heat collecting fins are installed inside the transparent outer tube to collect heat?Explanation of Embodiment 1 An embodiment of the present invention will be explained using FIG. 2.Inside the transparent glass outer tube 1, A copper heat collecting tube 2 equipped with aluminum heat collecting fins 3 is inserted, the inside of the outer tube 1 is kept in vacuum, and the surface 4,
Back side 6. ! : Also, selective absorption; model 4.6 was provided.

The sunlight is reflected by the sun and reaches the back side of the heat collecting fins 3, and the selective absorption film 6 formed on the back side of the heat collecting fins 3 effectively absorbs sunlight. This means that the outer tube 7.8
．． The same can be said for 10.11, and if there is sunlight reflected on the back side of the heat intensifier by a human-like reflector or a multi-layered object 13 such as a roof, Vj, reflected light 1
