Analysis of Heat Transfer Coefficient in Heat Pipe

Experimental study on heat transfer coefficient in a developed heat pipe

Abstract

The heat pipe is similar in construction to that of a thermo siphon but in this case, a wick constructed from a few layers of wire gauge, is fixed to the inner surface and capillary forces return condensate to the evaporator. In the heat pipe evaporator position is not restricted and it may be used in any orientation. In this paper a heat pipe of a 10 W capacity has been successfully developed, fabricated and tested. Different operating characteristics are presented at different heat inputs viz, 2W, 4W, 6W, 8W; 10W.
