Abstract: This paper described an experimental investigation on heat transfer performance of a micro-grooves phase change micro-cooling system for heat dissipation of high power electronic apparatus. The effects of distance from the reservoir surface of cooling medium to the center of heated zone, the size of grooves and the adoption of transverse grooves were discussed. The optimal distance from the reservoir surface of cooling medium to the center of heated zone and the optimal size of micro rectangular capillary grooves were obtained.
