Abstract

Abstract: Heat pipe radiators are popular as heat dissipation system of electronic components due to high heat transfer efficiency and reliability. This study proposed a metal foam heat pipe radiator to enhance heat transfer between heat pipe condensed section and air. The prototypes of traditional fins and metal foam heat pipe radiator were produced to validate the heat transfer enhancement. The effect of metal foam pore density on the heat dissipation capability was discussed. The experiment results showed that metal foam heat pipe radiator could improve the start-up time and part-load time in comparison with the traditional fins heat pipe radiator. The thermal resistance of proposed radiators could reduce by 10% when the pore density of copper foam is 5 PPI.
