Description
Summary:The channel heat sink is in contact with the working fluid to remove the heat. But much channel will result higher pressure difference issue in the micro multi-channel heat sink. In this paper, a ladder shape channel (link between the parallel channel) is proposed to correct the problem of high pressure difference. The design of the link decreases the pressure difference for reducing the pump work of the micro multichannel heat sink. The purpose of this paper is to maximize the efficiency of the micro multi-channel ladder shape heat sink by using optimization design. An optimization method based on the genetic algorithm and COMSOL 3-D conjugated thermal-fluid model is applied to establish the optimal geometry parameters of the link. The results show that this optimized heat sink design can improve the efficiency more than 43%. And the heat removal of the proposed device is significantly improved.
