<P>PROBLEM TO BE SOLVED: To provide a heat pipe capable of enhancing heat conduction efficiency. <P>SOLUTION: This heat pipe is provided with an outer shell 10 having a hollow storage chamber 11 in its inside, an acting fluid 20 provided in the storage chamber 11, and a core part 30 formed in an inner wall of the outer shell 10 to adsorb the acting fluid 20. The core part has the first portion 32 and the second portion 34, a clearance rate of the first portion is different from that of the second portion. Circulation resistance force of the acting fluid 20 can be reduced by providing an excellent flow function by the second portion 34 having the relatively high clearance rate, in a process with the acting fluid 20 circulated to a heat reception terminal part 12. The acting fluid 20 through the second portion 34 can be circulated continuously to the heat reception terminal part 12, by providing an excellent capillary function by the first portion 32 having the relatively low clearance rate. <P>COPYRIGHT: (C)2007,JPO&INPIT |
