Description
New type heat sinks using heat pipes for natural convective cooling of electronic equipments were developed. The heat sinks are the fin-and-tube heat exchanger type, the heat pipes are vertical tubes of 3 mm in diameter, and the fins are vended in order to increase heat transfer rate. Temperature distributions of the heat sinks were measured by changing the gap of flow spcing and the angle of fins. The new type heat sinks have 60% higher cooling rate compared with a convectional heat sink.
