Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a solar collector using heat pipes.

A conventional heat pipe type heat collector is a heat pipe 7 in which a heat receiving part 7a' is installed in a transparent tube 2' as shown in the fifth and sixth figures.
The heat supply portion 7b' of the heat transfer section 7b' is inserted into the heat medium pipe 9' and welded H at the protrusion portion.

In FIG. 5, 10' is a male nut, 11' is a cap nut, and 13' is a support plate.

Therefore, as shown in FIG. 5, a plurality of heat pipes 7 are
' has to be stored and transported with the heat pipe 9' attached to the heat pipe 9', which is cumbersome to handle, and if one heat pump breaks down during use, the heat pipe 7' and the heat pipe 9' The welded part H had to be heated with a gas burner or the like to remove it, and since the work was done in a place with poor footing, such as the roof of a house, the workability was poor and dangerous.

The present invention was developed in view of the above problems, and its main purpose is to facilitate the installation and removal of heat pipes.

An example will be explained below with reference to the figure. 1, 1...
- is a heat collecting element, with frit glass 3 at the opening of the transparent tube 2.
A connecting tube 5 is attached to the end plate 4 which is attached in a manner protruding from the end plate 4, and a heat receiving part 7 with heat collecting fins 6 is installed inside the transparent tube 2.
The heat supply part 7b of the heat pipe 7 charged with the heat pipe 7 is made to protrude from the connecting cylinder 5, and the connecting cylinder 5 and the heat pipe 7 are brazed together, and the exhaust tip pipe 8 attached to the connecting cylinder 5 is used. The inside of the transparent tube 2 is either evacuated or filled with an insulating gas.

A thread 5' is formed on the outer peripheral surface of the connecting cylinder 5, and the tip of the exhaust tip pipe 8 is positioned within the outer diameter of the connecting cylinder 5.

Reference numeral 9 denotes a heat medium pipe through which a heat medium such as water passes, and a male nut 10 and a cap nut 11 are attached to both ends for connection to other heat medium pipes.

Further, a screw tube 12 having a space on the circumferential side and communicating with the heat medium pipe 9 is provided.
There are several.

Then, the heat supply part 7b of each heat pipe 7 of the heat collecting elements 1, 1, . is screwed into the screw tube 12, and a plurality of heat collecting elements 1, 1 are attached to the heat medium pipe 9 to form a heat collector.

The tips of the heat collecting elements 1, 1... are L-shaped support plates 1
3 through packing 14.

Further, the heat medium pipe 9 is surrounded by a support box 15 containing a heat insulating material, and is installed at the installation location using the support box 15 and the L-shaped support plate 13.

Furthermore, a male nut attached to the heat medium pipe 9} 10 and a cap nut 11
Connect with other heat collectors to obtain the required heat collecting capacity.

FIG. 4 shows another embodiment of the present invention, in which the exhaust tip pipe 8 is located outside the shaft cylinder 5.

Furthermore, although a heat medium pipe has been described as an example, a similar spiral tube may be attached to a heat medium tank that stores a heat medium.

Further, although the explanation has been made regarding screwing the connecting cylinder and the heat medium pipe, etc., they may be attached by fitting or other means instead of screwing.

Since the present invention is as described above, it is easy to attach and detach the heat collecting element, heat medium pipe, etc.

That is, in the event of an accident in which the vacuum of the transparent tube is destroyed for some reason, only the relevant heat collecting element can be removed and easily replaced with a new one.

In addition, since the heat collecting element and heat medium pipe etc. can be separated, transported separately, and assembled at the installation site, inventory management and transportation are easy.
