て作動液12の液面が制御されている。Structure of Conventional Example and Its Problems A conventional heat transfer device of this type was constructed as shown in FIG. A heat exchange tank 2 storing hot water is arranged below a collector 1 (generator) consisting of a plurality of heat collecting pipes, and a check valve 4a is installed between the heat exchanger 3 housed in the tank 2 and the collector 1. They are connected by an outgoing pipe 5 provided with a. A liquid reservoir tank 7 in which a liquid level detection sensor 6 is housed is arranged above the collector 1, and the heat exchanger 3 is connected to a return pipe 8.
It is connected to the collector 1 by a return pipe 9 having a check valve 4b in the middle, and an on-off valve 10 (valve mechanism) is connected to the upper part of the liquid reservoir tank 7 and the upper part of the collector 1 in the middle. They are connected through a communication pipe 11 provided. The liquid level of the hydraulic fluid 12 is controlled by a controller 13 that opens the on-off valve 10 when the liquid level of the hydraulic fluid 12 detected by the liquid level detection sensor 6 becomes larger than a set value H.

作動液12のコレクタ1への回収は終了する。 The working fluid 12 boils and evaporates when the collector 1 is heated by sunlight, and by increasing the pressure inside the collector 1, the heated working fluid 12 passes through the outgoing pipe 5 and is pushed into the heat exchanger 3, and is transferred to the heat exchange tank. The working fluid 12 that has been cooled by exchanging heat with the hot water in the tank 2 is sent to the liquid storage tank 7 through the return pipe 8, and the level of the working fluid 12 in the liquid storage tank 7 gradually rises. go. When the liquid level of the hydraulic fluid 12 detected by the liquid level detection sensor 6 becomes larger than the set value H, the controller 1
3, the on-off valve 10 is opened and the collector 1 is opened.
The upper part of the collector tank 7 and the upper part of the liquid reservoir tank 7 are communicated with each other by a communication pipe 11, and the pressure inside the collector 1 is guided to the liquid reservoir tank 7.
is collected into the collector 1 through the return pipe 9. When the level of the hydraulic fluid 12 decreases and becomes smaller than the set value H, the controller 13 closes the on-off valve 10 and the collection of the hydraulic fluid 12 to the collector 1 is completed.

るといつた問題があつた。 In this configuration, when the working fluid 12 is collected into the collector 1, the high-temperature vapor of the working fluid 12 led from the upper part of the collector 1 through the communication pipe 11 into the fluid reservoir tank 7 is cooled by the inner wall of the fluid reservoir tank. Because of condensation, it is necessary to supply more steam from the collector 1 to the liquid storage tank 7 than the recovered amount of the working liquid 12, which causes a pressure loss in the communication pipe 11 and prevents the pressure inside the collector 1 from being properly guided to the liquid storage tank. As a result, the recovery of the hydraulic fluid 12 became difficult, and the liquid reservoir tank 7
The temperature of the working fluid 12 condensed in the collector 1 is increased, and the temperature of the working fluid 12 collected into the collector 1 is increased, which increases the heat collection temperature of the collector 1 and reduces the heat collection efficiency. In addition, the working fluid 12 heated in the collector 1 exchanges heat with hot water in the heat exchanger 3, is cooled, and flows through the return pipe 8 from the lower part of the fluid storage tank 7. The working fluid 12 is heated in the high-temperature liquid storage tank 7 by the heat of condensation of the steam that has been guided, and the inflowing working fluid 12 becomes high temperature and high pressure, so it passes from the collector 1 through the heat exchanger 3 to the liquid storage tank. There was a problem in that the working fluid 12 became difficult to flow into the heat exchanger 7 and the heat transfer performance from the collector 1 to the heat exchanger 3 deteriorated.

常に液溜めタンクへ導かれる。 With this configuration, when the working fluid is recovered to the generator, the high-temperature steam of the working fluid led from the top of the generator to the fluid reservoir tank through the communication pipe and the inner wall of the fluid reservoir tank are heated by the heat insulating material. Since the high-temperature steam is not condensed, the temperature of the liquid reservoir tank and the working fluid therein does not rise, and the pressure inside the generator is normally guided to the liquid reservoir tank.

1への回収は終了する。 When the collector 1 (generator) is heated by sunlight, the working fluid boils and evaporates, increasing the pressure inside the collector 1 and pushing out the heated working fluid 12 to the outgoing pipe 5.
The hot water is sent under pressure to the heat exchanger 3 through the heat exchanger tank 2, cooled by radiating heat to the hot water in the heat exchange tank 2, and then flows into the liquid storage tank 7 through the return pipe 8. When the hydraulic fluid 12 flows into the liquid reservoir tank 7 and the liquid level of the hydraulic fluid 12 detected by the liquid level detection sensor 6 becomes larger than the set value H, the controller 13 opens the on-off valve 10 and the collector 1 The upper part of the collector tank 7 and the upper part of the liquid reservoir tank 7 are communicated with each other by a communication pipe 11, and the high temperature steam in the collector 1 is guided to the liquid reservoir tank 7. Since the inner wall of the liquid storage tank 7 is covered with a heat insulating material 14, the high temperature steam is not cooled and does not condense. Therefore, the same amount of steam as the working fluid 12 recovered to the collector 1 is supplied from the collector 1 into the liquid reservoir tank 7, and the recovery of the working fluid 12 to the collector 1 progresses. When the liquid level of the hydraulic fluid 12 in the liquid reservoir tank 7 becomes smaller than the set value H, the on-off valve 10 is closed by the controller 13, and the collection of the hydraulic fluid 12 to the collector 1 is completed.

When recovering the working fluid 12 to is guided normally to the liquid storage tank 7 and the working fluid is smoothly collected, improving heat transfer performance, and low-temperature working fluid is collected to the collector 1, reducing the heat collection temperature and improving the heat collection efficiency. Since the liquid reservoir tank 7 is kept at a low temperature, the working fluid 12 flowing from the heat exchanger 3 does not reach high temperature and high pressure, but flows from the collector 1 through the heat exchanger 3 to the fluid reservoir tank 7. The flow rate increases, and the heat exchange capacity of the heat exchanger 3 improves.
