HEAT PIPE WITH WICK STRUCTURE OF SCREEN MESH

摘要

A heat pipe (10) includes a hollow pipe body (20) for receiving a working fluid therein and a screen mesh (30) disposed in the pipe body. The screen mesh includes at least two layers. One of the two layers is in the form of a planar layer (50) and the other is in the form of a wave layer (40). A plurality of flowing channels (48) is formed by the wave layer. The channels formed by the wave layer of the screen mesh are capable of reducing the flow resistance for the condensed fluid to flow back while pores in the screen mesh provide a relatively large capillary pressure for drawing the condensed fluid to flow back.
