PURPOSE:To provide a stable thermal transfer even if one end of the heat pipe is inclined by a method wherein a coil is inserted into the heat pipe end arranged at a heat radiating part in such a way as the coil is closely contacted with the pipe wall. CONSTITUTION:Coil 5 is inserted into the end part 1b of the heat pipe 1 installed in the soil with the coil being closely contacted with the pipe wall. Thus, the working fluid 2 flowed from the end of the heat pipe 1 with being liquefied is flowed to the other end 1b of the heat pipe and then flowed down along the helical passage. Thus, it becomes possible that the inner surface of the pipe wall is wet by the working fluid, a heat transfer area of the working fluid 2 may be increased even if the heat pipe 1 is buried with being slightly inclined and thereby a thermal transfer power may be stabilized. |
