Heat pipe

Abstract

A heat pipe has a hollow pipe body, a wick structure of screen mesh disposed on an internal wall of the pipe body and at least one support structure extended to press the wick structure of screen mesh tightly to the internal wall of the pipe wall. The support structure spiral in shape, and is formed by a continuous board. The support structure provides a support force to support the wick structure of screen mesh on the internal wall of the wick structure of screen mesh by a surface of the spiral board. The heat pipe provides capillary action.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a heat pipe, and especially to a spiral support structure for providing a support force to press the wick structure of screen mesh tightly to an internal wall of a pipe body. BACKGROUND OF THE INVENTION [0002] A heat pipe provides excellent heat-dissipation and high conductivity while being light, simple in structure and multifunctional. The heat pipe can thus dissipate a great amount of heat without using power and is adapted to electronic products. The heat pipe of the prior art has a wick structure of screen mesh that allows the work fluid to flow smoothly in the heat pipe by means of capillary action. [0003] However, the wick structure of screen mesh of the heat pipe of the prior art is tightly stuck to an internal wall of the pipe body by a sintering process. The sintering process will soften the wick structure of screen mesh, and the wick structure of screen mesh consequently cannot provide sufficient support to al...

AI Technical Summary

Benefits of technology

[0005] The primary object of the present invention is to provide a heat pipe. The heat pipe has a spiral support structure for providing a support force to the internal wall of the wick structure of screen mesh. The wick structure of screen mesh will provide an enough support force to press the wick structure of screen mesh tightly to an internal wall of a pipe body of the heat pipe. As a result, the heat pipe will provide capillary action.

Problems solved by technology

However, the wick structure of screen mesh of the heat pipe of the prior art is tightly stuck to an internal wall of the pipe body by a sintering process.

The sintering process will soften the wick structure of screen mesh, and the wick structure of screen mesh consequently cannot provide sufficient support to allow the wick structure of screen mesh to adhere tightly to the internal wall of the pipe body.
