Experiment Investigation on a Honeycomb Micro-channel Based Cooling System

CHENG Ting1,LUO Xiao-bing1,2,HUANG Su-yi1,LIU Sheng2,3(1.School of Energy and Power Engineering;2.Wuhan National Laboratory for optoelectronics;3.Institute of Micro-systems,Huazhong University of Science and Technology,Wuhan 430074,CHN)  
Heat dissipation by micro-channel heat sink provides a kind of new solution for thermal management.A kind of honeycomb micro-channel heat sink used for building a heat dissipation system is discussed.Experiments on such a system were conducted.The results demonstrate that with 13.3ml/s flow rate and room temperature of 32℃,the 17cm2 micro-channel heat sink can take out 233.63W heat,the corresponding heat flux of heat source is about 13.3W/cm2,in such a case,the temperature of the water inside the micro-channel heat sink is just about 52℃.It is also found that in order to take full advantage of micro-channel heat sink,without good heat exchange between system and environment for mini heat exchanger in present system,the micro-channel heat sink can not achieve good cooling effect.
