あった。Therefore, the circulation of the heat medium starts before the secondary side heat exchange m (4b) reaches a high temperature, and the low temperature water in the secondary side piping (6) flows into the heat storage tank (7). In some cases, the temperature inside the heat storage tank (7) may be lowered. In particular, in winter, when the outside temperature is low and the heat exchanger (4) and the secondary piping (6) are easily cooled, and there are many changes between sunny and cloudy skies, this solar heat collector is not suitable for heat storage. There was a problem in that the temperature inside the tank (7) was difficult to rise.

If it gets expensive,
Heat transport can be initiated by thermosiphoning of the heat medium circulation pipe.

In the heating medium circulation pipe (10), gravity was used to circulate the condensed heating medium liquid. Condensing section (1) in the heat storage tank (7)
0b) is arranged at a higher position than the installation position of the evaporation part (10a) in the heat exchanger (4), and
The pipe is always inclined in a certain direction so that the heat transfer liquid condensed in step b) flows smoothly down the heat transfer pipe. In addition, after removing the air from the heat medium circulation pipe 00) and creating a vacuum,
A heating medium liquid is sealed in about 10 to 50% of the internal volume.

る。Fig. 3 is an enlarged sectional view of the main parts showing one embodiment of the heat exchanger (4), including the primary side heat exchange part (4a) and the heat medium circulation pipe 00).
A coaxial double pipe was used to ensure efficient thermal contact. Although other heat exchange methods may be used, it is necessary to always provide an inclination in a certain direction so that the heat transfer liquid can smoothly circulate to the lowest end of the evaporation section (10a).

もたせている。Figure 4 shows the condensing section (1) of the heat medium circulation pipe (10) in Figure 2.
This condensing part (10b) is arranged at the lower part of the heat storage tank (7), and is sloped in a certain direction so that the heat transfer liquid smoothly flows back to the evaporating part (10B). It has a meaning.

加熱エネルギーは少なくてすむ。In the above configuration, an evaporation section (10a) having good thermal contact with the primary side heat exchange section (4a) is provided in the heat exchanger (4), and the number of heat medium liquid, for example, a fluorocarbon-based one, is provided. Compared to conventional water circulation systems, using a material with low specific heat,
Less heating energy is required.

熱槽（７）内の温度より少しでも高くなれば、直ちに熱
搬送するので、従来の水循環方式のように２次側配管内
の冷水部が蓄熱槽（７）内へ入り込んでしまうという欠
点は解消された。Furthermore, since the amount of latent heat transferred is large, only a small volume of heat medium liquid needs to be used, and less heating energy is required, making it possible to prevent wasteful energy loss. or,
If the temperature of the evaporator (10) installed in the heat exchanger (4) becomes even slightly higher than the temperature in the heat storage tank (7), heat is transferred immediately, so the secondary side is The drawback that the cold water part in the pipes enters the heat storage tank (7) has been solved.
さらに、雨天等で１次側熱交換部（４ａ）の温度が低い
場合番こは熱媒液は蒸発部（１０ａ）に溜ったまま作動
しないので、獲得した熱の逆流を防ぐことができ、放熱
ロスはほとんどない。Furthermore, when the temperature of the primary heat exchange section (4a) is low due to rainy weather, etc., the heat transfer liquid remains in the evaporation section (10a) and does not operate, which prevents the acquired heat from flowing back. There is almost no heat loss.

きた。Further, the cold water portion in the secondary side piping does not enter the heat storage tank unlike in the conventional case. At the same time, less energy is required to heat the working fluid in the heat medium circulation pipe than when heating water in the secondary pipe (so-called dead water), making the solar heat obtained from the collector (1) more effective. was able to be used for. The secondary heat exchanger used to consist of two pipes for going out and returning, but now it only needs one thin tube corresponding to the amount of latent heat transferred by the heat medium circulation pipe, and the cost can be reduced.

とがない。Effects of the invention ■ Since the secondary side heat exchange part of the heat exchanger is used as the evaporation part of the heat medium circulation pipe, the heat from the primary side heat exchange part can be immediately transferred to the heat storage tank, so it is not possible to collect heat as in the conventional case. There is no possibility that the cold water part in the secondary piping will be sent into the heat storage tank immediately after the start of operation.
