Head from a certain number of sintered metal powder in the tube wall and the wall surface and formed one of the sintered powder core, the core is higher capillary suction power, and greatly improve the radial resistance to overcome the poor reproducibility of core network the shortcomings of the decline of sintering heat pipe heat-can be balanced with low thermal resistance of considerations. Since the decline of sintering heat pipe with the heat-resistance and low volume of the merits of the actual application of laptop cooling, particularly when a distinct competitive edge.
