Heat Transport Performance Test of COSMOS Heat Pipe by use of Dual Piezo-Pump

Abstract

In the present report, thermal performance of a thin heat spreader composed of a COSMOS heat pipe and a dual piezo pump was experimentally investigated. The result indicated that, for temperature gradient of about 500K/m, the heat transport rate of this heat spreader was as high as 20W and the rate of pumping power to the heat transport rate was about 0.18%.
