ABSTRACT

This paper presents the thermal performance of a low-cost loop heat pipe (LHP) consisting of a single evaporator and a single condenser. The evaporator has an outer diameter of 14mm and a length of 50mm. An organic solvent was used as the working fluid. The low-cost LHP was made possible through a new manufacturing process. The LHP demonstrated excellent performance over heat loads ranging from 1W to 150W and sink temperatures between 243K and 293K. Tests performed included start-up, low power, power ramp up, high power, rapid power change, and rapid sink temperature change. No performance anomalies were seen.
