ABSTRACT:
A sealing structure formed at an end of a heat pipe, includes a two-layer structure, which can be divided into two walls and a rib interconnecting the walls together, wherein the rib points to a center of the heat pipe. A method for manufacturing the sealing structure includes following steps: (1) providing a metallic pipe with an end sealed and an opposite open portion; (2) pressing the open portion of the pipe to form the two-layer sealing structure by using a pair of pressing molds, wherein the pair of pressing molds comprises a first pressing mold and a second pressing mold, the first mold having an M-shaped convex portion, the second mold having an M-shaped concave portion corresponding to the convex portion.
