Zhu Kai, Yang Yang, Wei Jie, et al. Analysis for Fields Synergy in Heat Dissipation Process of Heat Sink[J]. Journal of refrigeration, 2014, 35(4). DOI: 10.3969/j.issn.0253-4339.2014.04.088.
CPU cooling problem has always been the focus of industry experts. Some novel heat sinks were presented to enhance the heat transfer effect during heat transfer process. A mathematic model of the CPU heat sink in the experiment duct was developed and compared with experiments. Based on the experiment research of the CPU heat sink
the velocity field and the velocity gradient field of the heat sink in the duct were acquired by PIV and fluid-solid coupling numerical calculation. It is showed that the synergy of the velocity field and the velocity gradient field in an entire flow domain would affect the heat convection of CPU heat sink. The results of the study are possible to improve the performance and the design of CPU cooling system.
