FIG. 1 shows an embodiment in which the present invention is applied to a heat pipe type solar collector. 10 is a heat collecting section, and 20 is a heat exchange section. Heat collecting part 10
is composed of an outer tube 16 and a heat pipe 12 which is a heat collecting tube housed inside the outer tube 16. The heat pipe 12 is arranged to be inclined so that the working liquid 18 is stored at one end of the heat pipe 12 by gravity. The other end of the heat pipe 12 is
It is branched and connected to one end of another sealed tube 30 inside the heat exchange section 20 . A liquid receiving tank 32 is provided at the other end of this sealed tube. An object that causes capillary action, that is, a stranded wire 14, is provided from one end of the heat pipe 12 to the liquid receiving tank 32. The wall thickness of the liquid receiving tank 32 is made thicker than the wall thickness of the heat pipe 12 so as to prevent damage during freezing.

ある。 When the heat pipe 12 stops operating, the working liquid 18 stored at one end of the heat pipe 12 infiltrates the stranded wire 14 due to surface tension and is moved to the liquid receiving tank 32 via the sealed tube 30. In this embodiment, the stranded wire 14 extends to the liquid receiving tank 32. However, if the liquid receiving tank is placed below the heat exchanger 20 (in a direction close to the ground), the working liquid
8 can be utilized, it is sufficient that the stranded wire 14 extends to one end (inlet) of the sealed tube 30.

である。 It is clear that the function of the heat pipe can be further improved by using wire mesh or metallic cloth to cover the inner wall of the heat pipe instead of the stranded wires 14.

FIG. 2 shows a state in which the operation of the heat collector is stopped. 18 is a stored liquid. In operation, liquid in tank 44 is circulated and heated within U-tube 26, driven by pump 42.

損しないという効果がある。 Branch pipe 30 provided inside the U-shaped pipe and at the outlet of the U-shaped pipe
A metal stranded wire or glass fiber string 14 is passed between them. The other end of the string is at a lower position than the tip of the U-shaped tube. The heat medium at the tip of the U-shaped tube infiltrates the string 14 and drips from the other end of the string due to gravity, so it is possible to remove the heat medium from the tip of the U-shaped tube and eliminate the liquid level, so even when frozen, the tip of the U-shaped tube This has the effect that it will not be damaged.
