PURPOSE:To prevent the increase in the resistance to heat conduction of a flexible heat pipe by a construction wherein the outer member is constituted by a corrugated pipe, the outer peripheral wall of which is of a corrugated shape having a smaller pitch and the inner peripheral surface of which has a soft wick pressed against and fixedly secured thereto by wick retainers. CONSTITUTION:A metal pipe 1 forming an outer member is a corrugated pipe having a predetermined pitch P, and its outer peripheral wall is of corrugated shape having a smaller pitch P. Inserted in the corrugated metal pipe 1 is soft tubular wick 2 such as gauze made of fine metal wires. The wick 2 is thrusted tightly against the inner peripheral surface of the corrugated pipe 1 by coiled spring like wick retainers which are inserted in the inner peripheral surface of the wick. Thus, the increase in the resistance to heat conduction of the flexible heat pipe can be prevented. |
