Heat Transport Device with Boiling-Driven Recirculating Flow

摘要

A new heat transport device using phase change has been developed. The device consisted of two different diameter parallel tubes which connected a heat source (electrically heated evaporator) and a heat sink (water cooled condenser). Experiments were conducted systematically using water as working fluid. It was confirmed that one way re-circulating flow through evaporator, larger-diameter tube, condenser and smaller-diameter tube was maintained to occur, and the heat transport performance of the device was far better than the conventional heat pipe of equivalent diameter and length.
