Abstract
The enhancement for cooling performance of heat sink is surely necessary to guarantee the performance of electronic products. So in this paper, the cooling performances of the aluminum heat sink with pulsating heat pipe(PHP) were investigated experimentally and numerically. The pulsating heat pipe was used as a heat spreader. Working fluid of PHP was R-22. Heat inputs were 30W, 60W, 80W and 100W, respectively. Heat sink was tested for forced convection conditions with air velocity of 1 ~ 4m/s. And CFD simulations were conducted for two different heat sinks. The results showed that the cooling performance of heat sink with pulsating heat pipe was higher than that of conventional heat sink. Therefore, the pulsating heat pipe can be a good tool to improve cooling performance of heat sink.
