Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a heat collector that includes a transparent outer tube made of glass or the like on the outer periphery of a heat collection pipe that serves as a passage for a heat medium such as water.

Since the heat collecting pipe 8' is filled with a heat medium such as water, it becomes heavy and curves at the center, causing it to come into contact with the outer tube or break the outer tube 1'.

Therefore, a support ring 11' for supporting the heat collecting pipe 8' is disposed inside the outer tube 1'.

However, the support ring 11' is fixed to the heat collecting member in advance, and when inserting the heat collecting member into the outer tube, the support ring 11' is compressed inwardly. The width of the heat collecting plate 9' is narrowed as shown in the first and second figures in order to provide enough room for compression.
The heat collection area of the heat collection plate was small.

Generally, heat collection efficiency can be significantly improved by increasing the heat collection area, so it is necessary to make maximum use of the limited narrow space inside the outer tube, but this has not been possible in the past.

This invention was devised in view of this point, and is shown in Figures 3 and 4 below.
To explain the diagram, 1 is a translucent outer tube made of glass, etc., 2,
Reference numeral 3 denotes a metal end plate for sealing the openings at both ends of the outer tube.One end plate 2 has a bellows 4 and a support tube 5 attached thereto, and the other end plate 3 has a support tube 6 attached thereto.

7 is a copper heat collecting pipe 8 disposed inside the outer tube 1 and the pipe 8;

, 6 and are brazed to the tips of the support tubes 5, 6.

Further, the heat collecting plate 9 has a size such that both ends thereof have a small gap between them and the inner peripheral surface of the outer tube 1.

Then, the inside of the outer tube 1 is evacuated using the exhaust tip 10 attached to the support tube 5, thereby creating an adiabatic space.

Reference numeral 11 denotes an appropriate number of support rings attached to the heat collecting member 7 such as the heat collecting pipe 8, which are formed by bending wire rods so as to be in contact with the inner circumferential surface of the outer tube 1.

Reference numeral 12 denotes a notch provided in the edge portion of the heat collecting plate 9 corresponding to the support ring 11, and serves as an escape portion for the wire of the support ring 11.

Therefore, in the present invention, the corresponding heat collecting plate of the support ring is provided with a notch, so that the heat collecting plate can be brought close to the inner circumferential surface of the outer tube without making the entire heat collecting plate smaller than the inner diameter of the ring, thereby increasing the heat collecting area.

The mesh-shaped portion in FIG. 3 is an increased portion compared to the conventional heat collecting plate, and the heat collecting effect is improved.

Furthermore, when inserting the heat collecting member into the outer tube, the support ring is generally inserted into the outer tube while being in contact with the inner circumferential surface of the outer tube, so the support ring may bend or fall due to the resistance during bending. Since the ring is locked by the notch provided in the heat collecting plate, it is prevented from bending or falling when inserted into the outer tube, and the function of the support rod is not impaired, and the assembly work efficiency can be improved. be effective.
