HEAT PIPE WITH SCREEN MESH WICK STRUCTURE

摘要

A heat pipe ( 10 ) includes a pipe body ( 20 ) having an inner wall ( 22 ) and a screen mesh ( 30 ) disposed on the inner wall of the pipe body. The screen mesh is in the form of a multi-layer structure with at least one layer thereof having an average pore size different from that of the other layers. The layer with large-sized pores is capable of reducing the flow resistance to the condensed fluid to flow back, whereas the layer with small-size pores is capable of providing a relatively large capillary pressure for drawing the condensed fluid from the condensing section to the evaporating section.
