<P>PROBLEM TO BE SOLVED: To provide a loop-type heat pipe, having high cooling performance and restraining the occurrence of dry-out. <P>SOLUTION: This loop-type heat pipe includes: an evaporating part 100, which receives heat from a heating unit to evaporate a working fluid of a liquid phase; a condensing part, which condenses the working fluid of a vapor phase by radiation of heat; and a pipe for circulating the working fluid between the evaporating part 100 and the condensing part, wherein the evaporating part 100 includes: a branch part 110 for causing the working fluid of a liquid phase flowing in from the condensing part to branch off; three evaporators 120 arranged side by side, which receive the working fluid of a liquid phase branching at the branching part 110 to cause a phase change to a vapor phase, and delivering the same, and have a double pipe structure in which a porous cylindrical wick 123 is inserted in a copper pipe 121; a focusing part 130, which focuses the working fluid of a vapor phase flowing out rom three evaporators 120 into one; an evaporator housing body 140 housing three evaporators 120; and a heat insulating material 150 covering the top face of the evaporator housing body 140. <P>COPYRIGHT: (C)2009,JPO&INPIT |
