HEAT PIPE WITH CAPILLARY WICK

摘要

A heat pipe includes a cylinder-shaped casing ( 100 ) containing a working fluid therein and a capillary wick ( 200 ) arranged on an inner wall of the casing. The capillary wick encloses a vapor passage ( 300 ) in a center of the casing. The capillary wick includes a plurality of shaped foils stacked on the inner wall of the casing along a radial direction thereof. The foils are sintered to the inner wall of the casing and define a multi-channel structure for the working fluid to flow from a condensing section to an evaporating section of the heat pipe.
