Description

[Detailed Description of the Invention] The present invention is designed to simplify the installation of the heat collecting pipe of the heat collecting plate in a solar collector.

Conventionally, a concave groove 2 is formed in the heat collecting plate 1 as shown in FIG. A fitting cylinder 4 was provided in advance as shown in the figure, and the heat collecting pipe 3 was fitted into this fitting cylinder.

Therefore, in the former case, when brazing, the heat collecting plate and the heat collecting pipe must be fixed each time with fixtures, and a heating furnace is also required, resulting in high production costs.

Moreover, in the latter case, it is complicated to shape the fitting cylinder, and it is also not easy to fit the fittings together, resulting in high production costs.

To deal with the above-mentioned problem, a plurality of notches are cut in the heat collecting plate at intervals and partition pieces are arranged side by side, and the partition pieces are alternately bulged in opposite directions in a semicircular shape to form a series of With a fitting groove,
The heat collecting pipe may be fitted into the fitting groove.

However, if the fitting between the heat collecting plate and the pipe becomes loose, the heat collecting plate will rotate and the positional relationship between the heat collecting plate and the sun will be out of the optimum state, reducing heat collection efficiency. will occur.

In view of the above-mentioned problems, the present invention aims to easily integrate a heat collecting pipe and a heat collecting plate, as well as to prevent rotational deviation of the heat collecting pipe and a decrease in heat collecting efficiency.
An example of this will be described below with reference to FIG. 3 and subsequent figures.

It is shaped like...

9 is an aluminum or copper heat collection pipe that passes heat medium such as water,
It fits into the series of fitting grooves 8, 8, . . . .

After the heat collecting pipe 9 is fitted, as shown in Fig. 5, the heat collecting pipe 9 is lightly pressed flat from the front and back sides to form the flat part 10 to prevent rotational deviation between the heat collecting plate and the pipe and to prevent contact between the two. make it good.

If necessary, a pair of engagement holes 11 are formed near the opening end of the fitting groove 8 as shown in FIG. The elastic force of this spring piece 12 improves the contact between the heat collecting plate and the pipe.

Furthermore, these heat collectors may be housed in a translucent tube made of glass or the like, with only the heat collecting pipe protruding from a stem that seals both ends of the translucent tube, and the interior of the translucent tube may be evacuated. .

As described above, the present invention involves carving a plurality of notches at intervals in a heat collecting plate and arranging the partition pieces in parallel, and the partition pieces are alternately bulged out in opposite directions in a semicircular shape to form a series of fittings. A heat collecting pipe is fitted into the fitting groove, and the semicircular bulge is pressed to form a flat part.

According to the present invention having the above-mentioned structure, the heat collecting pipe and the heat collecting plate can be integrated very easily and the production cost can be reduced.

In addition, since the flat part was fixed by pressing, even if the fitting between the heat collecting plate and the pipe becomes loose while the heat collecting plate repeats thermal expansion and contraction, the heat collecting plate will rotate naturally. It is possible to always obtain the optimum heat collection surface and maintain the initial heat collection efficiency.
