is the cooling part of the heat pipe, and 8 is the excess working liquid. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims

[Scope of utility model registration request]

What is claimed is: 1. A heat pipe having a capillary pressure generating cap inside the tube and a working fluid causing a phase change inside the tube, characterized in that the cross-sectional shape of the tube is convex.
