Abstract
In the present experimental and theoretical study, main purpose is to find out the performance limiting factors of thin heat pipe with new fiber wick structure. As the limiting factors we mainly focused on Cu pipe structure, wettability, capillary force, liquid flow area, vapor flow area and mechanical damage. In this paper, relation between the thermal performance of heat pipes with different thickness and width are showed. With the effective length of heat pipe is 125mm; maximum heat transfer capability of 0.8, 1.2, 1.5 and 2.0mm thick heat pipes are 7W, 15W, 25W, 34W and 42W respectively. Also, the theoretically achieved relation between the total pressure drop, liquid flow area and vapor flow area with different Cu pipe structure is shown.
