Abstract
A heat pipe capillary wick constructed from a sintered metal cylinder formed in close contact with the inner diameter of the heat pipe casing, and containing longitudinal grooves on the wick's inner surface, adjacent to the vapor space. The grooves provide longitudinal capillary pumping while the high capillary pressure of the sintered wick provides liquid to fill the grooves and assure effective circumferential distribution of liquid in the heat pipe.
