Capillary pumped loop for cooling of electronic devices

Abstract

Capillary pumps are passive, two-phase heat transport systems that use the capillary pressure in a porous material in an evaporator to force circulation of cooling medium flow. The Capillary Pumped Loop (CPL) has been designed, built and investigated. Pump is destined for cooling of electronic component, which work with maximum temperature about 100°C. Contact surface is 50x50mm. Investigating the static parameters of the pump is the purpose of this paper. The results indicate that a pump takes off 100-200W from the electronic device at 100°C near the surface of the power source.
