PROBLEM TO BE SOLVED: To realize excellent heat transfer performance by passing a plurality of holes at both or one side end of a sealed container, and inserting wick members only partial holes of them thereby smoothly circulating vapor and liquid phase of working fluid. SOLUTION: Wick members 20 are inserted into every other holes 12. Each member 20 is made of an aluminum wire. Three wires are inserted into one hole 12. A cap member 11 is welded to be connected to both ends of the container 10. Substitute fluorocarbon HCFC 123 is contained in an amount corresponding to 45% of a cavity volume except a volume of the member 20 as the fluid in the cavity formed via the thus communicated holes 12, and this plate type heat pipe is operated. In this case, a heat absorbing unit and a heat radiating unit are disposed to be substantially parallel to one another. As a result, it is confirmed that dry-out of the fluid scarcely occurs and circulation of the fluid is sufficient. |
