Abstract :
Heat generation from very large-scale integrated (VLSI) circuits increases with the advent of high-density integrated circuit technology. One of the promising techniques is liquid cooling by using microchannel heat exchanger. This work proposes a scheme for microchannel heat exchanger optimization with the constraint of pump. The cooling performance of microchannel heat exchanger was analyzed by constraining the flow rate and pressure drop of the pump used in this work. The minimum thermal resistance of the microchannel heat exchanger was calculated by using channel flow theory. And experiments were also conducted to verify the results from the channel flow theory. Based on the optimization process from this paper, the dimension of microchannel heat exchanger is proposed for maximum cooling efficiency with the given pump
