PURPOSE:To enable to ensure high heat conveying performance even when the amount of solar radiation is large without making the size of absorbing pipe larger by a structure wherein the figure of a loop type heat pipe is improved. CONSTITUTION:A light transmitting body is arranged at the front surface of a collector 6, in the interior of which an evaporator section 11 consisting of a plurality of absorber pipes 10 equipped with an absorber plate 9 communicating between an upper header 7 and a lower header 8 is provided. A condenser section 14, to one end of which the upper header 7 is communicated through a flow pipe 15 and to the other end of which the lower header 8 is communicated through a return pipe 16, is arranged in the interior of a heat exchange tank 13 located above the collector 6. At the same time the junction part 17 of the flow pipe 15 and the upper header 7 is arranged at the position far away from the absorber pipes 10. Consequently, even when the flow speed of vapor in the upper header 7 becomes larger due to the increase of evaporation, no liquid after being separated from vapor flows in the flow pipe 15 and also no resultant lowering of condensation heat transfer rate occurs at the condenser section, resulting in ensuring high heat conveying performance. |
