Abstract

A novel heat spreader was developed with its main cavity of copper tube, where copper mesh and support structure was served as the capillary constructions. The size of the support structure was 73 mm × 48.5 mm × 2.7 mm. Ceramic heater, 30 mm × 30 mm, was used as the heating source with the output power from 10 Watts to 130 Watts, and utilized the heat sink integrated with fan as the cooler. De-ion water was employed as the working fluid with the same filling charge. When heating power was 130 Watts, the temperature of heat source in heat spreader was lower than in copper plate about 4.3°C.
