ある。Configuration of the conventional example and its problems The conventional example will be explained based on the drawings. FIG. 1 is an external view of a solar water heater configured to include a heat collecting section 1 and a heat storage tank 2, and a reflector plate 3 provided on the front surface of the heat storage tank 2.

なかつたのである。 Next, the heat pipe 6 on the heat collecting part 1 side of the heat pipe 4 in FIG. 2 is installed under the glass 7,
When solar heat is absorbed, latent heat of evaporation of the refrigerant is generated, and the latent heat of evaporation is transferred to the heat pipe 4 inserted into the stored hot water 8 of the tank 5 inside the heat storage tank 2, where it is cooled by the stored hot water 8, and the latent heat of evaporation is transferred to the stored hot water. Transfer heat to 8. After the heat transfer, the refrigerant in the heat pipe 4 is liquefied and returns to the heat pipe 6 of the heat collecting section 1 to receive solar heat. By repeating this process, the solar heat received by the heat collecting part 1 is transmitted to the hot water 8 in the heat storage tank 2, and the temperature of the hot water 8 is increased. In this case, when the refrigerant absorbs solar heat, it evaporates and rises in the heat pipe 6 , and then, after transferring heat to the hot water storage 8 in the heat pipe 4 , it liquefies and descends into the heat pipe 6 . In other words, the refrigerant repeatedly rises and falls simultaneously within the same pipe. This means that the refrigerant whose temperature has risen (evaporated) due to solar heat comes into contact with the lower-temperature refrigerant that is descending on the way up, and as a result, the temperature decreases as it rises, and therefore, when heat is transferred to the hot water storage 8, the temperature decreases.
Even though the temperature of the stored hot water 8 is raised, the efficiency of heat exchange is low. In other words, heat transfer occurs between the refrigerant rising and falling within the heat pipe 6, and solar heat is not effectively utilized.

としている。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 3, a heat pipe 10 formed in a U-shape with a small diameter is installed under the heat collecting glass 9. The upper end of the heat pipe 10 becomes a large-diameter heat pipe 11, which is inserted into a tank 13 in a heat storage tank 12, and is water-sealed with a packing 14. One end of the U-shaped heat pipe 10 is connected to the lower part and upper part of the large diameter heat pipe 11,
The other end of the U-shaped pipe 10 is a large diameter heat pipe 1
It is connected to the lower lowest part of 1. Furthermore, the U-shaped parallel portions of the small diameter heat pipe 10 are press-joined to the L-shaped heat collecting plate 15, and the U-shaped part has a large diameter 10a.
It is said that

くするものである。 When solar heat is transferred to the heat pipe 10 of the heat collection glass 9, the refrigerant becomes evaporative latent heat, moves to the heat pipe 11 on the heat storage tank 12 side, transfers the heat carried to the surrounding hot water 16, and after the transfer is completed, the heat is released. The refrigerant in the pipe 11 is liquefied again, returns to the heat collecting portion glass 9 side, and repeats heat collection. This increases the temperature of the hot water 16 in the heat storage tank 12.
As described above, according to this embodiment, the refrigerant that has been heated up by solar heat and evaporated rises in the small diameter heat pipe 10 and transfers heat to the stored hot water 16 through the large diameter heat pipe 11 section. After the transfer is completed, the temperature of the refrigerant decreases, the refrigerant liquefies, and drips into the lowest part of the heat pipe 11, where it liquefies. At this time, the liquid refrigerant descends from the lower end opening of the heat pipe 10 through the lower part of the U shape, flows into the lowermost large diameter section 10a of the heat pipe 10, and begins to rise in temperature due to solar heat inside the heat pipe 10. The existing liquid refrigerant at the top of the letter is pushed further upwards. In other words, the rising and falling refrigerant is separated by the U-shaped heat pipe 10 to eliminate heat exchange between the refrigerants.
この場合、ヒートパイプ１０のＵ字の下部をＬ

循環の速度を速めることができる。 In this case, the lower part of the U shape of the heat pipe 10 is
If the solar heat is not pressed and bonded to the letter-shaped heat collecting plate 15, there will be no heat conduction of solar heat through the heat collecting plate 15, and the temperature will drop without rising, thereby increasing the speed of the so-called natural circulation of the refrigerant in the loop.

せる効果がある。 Further, the large diameter portion 10a at the bottom of the tip of the small diameter heat pipe 10 is a turning point of the upward and downward movement of the natural circulation of the refrigerant, and is a pool of flow. As the vapor rises faster, the inside of the large-diameter portion 10a becomes a negative pressure state, which has the effect of accelerating the descent of the refrigerant at the lower part of the U-shape.

環を高効率のものとすることができる。Effects of the invention According to the invention, each of the plurality of heat pipes on the heat collecting part side is formed into a U-shape, and the lower end of this U-shape has a large diameter, so that the refrigerant is sufficiently supplied to the large diameter part. Therefore, solar heat can be efficiently stored in the heat storage tank without suppressing the heat collection operation due to lack of refrigerant during the solar heat collection function. Furthermore, since the heat collecting plate part and the U-shaped heat pipe are integrated, it can be made compact, and is expected to be more effective in terms of ease of assembly, visual inspection of functions, and repair and serviceability. Become what you can.
In addition, by integrating the heat collecting plate part, a small diameter U
This can be used as reinforcement to prevent accidents such as breakage of the letter-shaped heat pipe portion. Since the lower part of the U-shape passes through the heat collecting plate directly below the upper part of the U-shape, it absorbs the difference in thermal expansion between the upper and lower parts of the U-shape and directs it to a specific weak point. In addition, the lower part of the U-shape is directly under the upper part and is not exposed to sunlight, so that the natural circulation of the refrigerant for heat transfer can be made highly efficient.
