Flat heat pipe with hook capillary tissue

Abstract

A flat heat pipe with hook capillary tissue includes a metal pipe, a capillary tissue and working fluid. The metal pipe is in a flat shape and formed by enclosing two opposite panels and two opposite sidewalls, and a hollow chamber is formed in the metal pipe. The capillary tissue is in the shape of a long strip, and includes having a hook formed at an end of the capillary tissue, and the capillary tissue is contained in the hollow chamber and attached onto one of the sidewalls and abutted between two sidewalls, and a working fluid is filled into the hollow chamber and adhered to the capillary tissue, so that the stability of fixing the capillary tissue into the metal pipe can be improved, and the retention quantity of the working fluid at an end of the pipe can be maintained.
