PURPOSE:To contrive to improve the heat performance further more by surely maintaining volatile heat transfer medium in a two-phase region within a collector or evaporating section by a structure wherein the inlet of the volatile heat transfer medium to the collector is located at one end of an upper header, at the other end of which the outlet of the volatile heat transfer medium leaving the collector. CONSTITUTION:A collector 1 consists of a plurality of absorber pipes 7 acting as the evaporation section of volatile heat transfer medium, absorber plates 8, each of which collects the solar heat in order to transmit it to the absorber pipe 7, a lower header 9 to connect the lower ends of the respective absorber pipes 7 and an upper header 10 to connect the upper ends of the respective absorber pipes 7. Further, a flow pipe to the collector 1 of a heat collecting circuit 6 is connected to one end of the upper header 10, to the other end of which a return pipe from the collector 1 of the heat collecting circuit 6 (not shown in fig.) is connected. Because each absorber pipe 7 acts as a gravity type heat pipe within the collector 1, the two-phase region is maintained within the collector 1 even if the conditions of the insolation changes and the rate of circulation of the volatile heat transfer medium in the heat collecting circuit 6 is left uncontrolled.

1 is a collector that collects solar heat and has an evaporation part for an evaporative heat medium inside, 2 is a heat storage tank that houses a heat exchanger 3 which is a condensation part for the evaporative heat medium, and 4 is a condensing part. The evaporative heat medium receiving tank 5 is a heat collection pump that circulates the evaporative heat medium between the collector 1, which is a total evaporation part, and the heat exchanger 3, which is a condensation part.
is formed. The collector 1 includes a plurality of heat collecting pipes 7 which serve as evaporation parts for the evaporative heat medium, a heat collecting plate 8 which collects all solar heat and transmits the heat to the heat collecting pipes 7, and a lower header 9 which connects the lower ends of each heat collecting pipe 7. One end of the upper header 10 is connected to the outgoing pipe of the heat collection circuit 6 to the collector 1, and the other end of the upper header 10 is connected to the heat collection path 6. A return pipe from collector 1 is connected.

In the above configuration, the heat collection circuit 6 is made into a vacuum state and an evaporative heat medium such as fluorocarbon is normally sealed in the heat collection circuit 6, but the amount of solar radiation increases and the temperature of the collector 1 is higher than that of the heat storage tank 2. When the heat collecting pump 5 is started, the liquid evaporative heat medium enters one end of the upper header 10 of the collector 1 and flows out to the other end, entraining the gas evaporated in each of the heat collecting pipes 7, and causing the liquid to flow into the upper header 10 of the collector 1. Due to the heat cycle, the evaporative heat medium that comes out of the upper header 1071 is in a two-phase region, and is condensed in the heat exchanger 3, where it is re-evaporated. The evaporative heat medium is sent from the liquid receiving tank 4 to the collector 1 again by the heat collection pump 5, and by repeating the cycle, solar heat is stored in the heat storage tank 2.

Inside the collector 1, each heat collection tube 7 acts as a gravity-type heat pipe, so even if the solar radiation conditions change, the amount of heat collected by the evaporative heat medium remains constant! The two-phase region is maintained even without controlling the circulation amount at 1i156, and the upper header 1
0, the efficiency is high because the circulating evaporative heat medium and the evaporative heat medium of each heat collecting pipe 7 are in direct contact with each other, and furthermore, since the lower ends of each heat collecting pipe 7 are connected by the lower header 9, Since the liquid level of the evaporative heat medium is not uniform, the amount of evaporation in each heat collecting pipe 7 is approximately uniform.

Next, another embodiment of the present invention will be explained with reference to FIG. This embodiment is different from the above-mentioned embodiment in that the upper and lower headers 10°9 are connected through a bypass pipe 11. According to this configuration, even if the amount of heat collected increases and the steam ejects from the heat collecting pipe 7 becomes intense, and the drop of the heat medium at the center of the heat collecting pipe 7 becomes obstructive, the bypass pipe 11 Since the heat medium is supplied to the lower header 9, the heat collection performance does not deteriorate.

As described in detail, the present invention provides a two-part header connected to a lower header at each end of a small number of heat collecting tubes in a collector, with the inlet of the evaporative heat transfer medium to the collector being one end of the upper header. Since the other end of the upper header is an outlet from all the collectors, (1) each heat collecting pipe in the collector can constantly collect heat uniformly in the two-phase region, and even if the solar radiation conditions change, the heat can be collected in a stable state. Operation is possible and heat collection performance is improved.

(2) Since there is no need to add any new equipment to control the flow rate of the circulating evaporative heat medium, the cost is low and the reliability is high.
