Loop type heat pipe and loop type heat pipe manufacturing method

摘要

A loop-type heat pipe and a loop-type heat pipe manufacturing method capable of efficiently transporting heat by reducing the resistance received by hydraulic fluid from a pipeline. SOLUTION: An intermediate metal layer 22 in which a looped pipeline 15 is formed, a lower metal layer 21 and an upper metal layer 23 joined to the intermediate metal layer 22, and a working fluid C enclosed in a pipeline 17. A vapor line 15 through which the vapor Cv of the hydraulic fluid C flows, and a line 17 between the evaporator 13 and the condenser 14 provided in the line 17 and the line between the evaporator 13 and the condenser 14 A conduit 17 between the vessel 13 and the condenser 14, and a liquid pipe 16 through which the liquid hydraulic fluid C flows, in any part of the condenser 14, the liquid pipe 16, and the steam pipe 15 The loop heat pipe 11 is characterized in that at least one of the lower metal layer 21 and the upper metal layer 23 expands outward of the conduit 17.
