Claims

[Scope of utility model registration request]

The evaporation section of a loop-type heat pipe is housed in a loop-type heat pipe having a lower header pipe that communicates the lower ends of a plurality of heat collection pipes arranged on a heat collection plate and an upper header pipe that communicates the upper ends of the plurality of heat collection pipes. a condensing section of a loop heat pipe, which is located above the collector and has both ends communicating with one end of an upper header tube and one end of a lower header tube that constitute the evaporation section; an internal hot water storage tank, the condensing section is connected to one end of the upper header pipe via an outgoing pipe, and an upper heat dissipation pipe and one end of the lower header pipe are provided with a height difference between both ends; Consisting of a lower heat radiation pipe that communicates via a return pipe and has a height difference between both ends, and an intermediate heat radiation pipe provided between the lower heat radiation pipe and the upper heat radiation pipe so as to communicate with them. and a loop heat pipe type solar water heater provided with a bypass pipe that bypasses the intermediate heat radiation pipe and a portion of the lower heat radiation pipe that is close to the return pipe.
