Abstract
Recently, high-performance electronic devices generated more heat than former. Mini-channel liquid coolers should be studied, to dissipate heat generated by the high-power electronic devices. In this research, the performances of swirling-cold-plates with different channel designs by using water as the cooling fluid were studied with different flow rate.. The results of experiment were measured and analyzed. The influence of the swirling structures on the heat transfer efficiency of liquid-cooling cold-plate can be predicted under some reasonable assumptions. The theoretical predictions were well verified by experimental analyses. The nondimensional relationship between heat transfer coefficient and relative parameters can be established during a lot of precision experiments. These parameters include geometric structure of swirling channel, properties and flow rate of cooling fluid, and heat dissipation rate demanded.
