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 Y.P. Wang’s thesis (2007), it is mentioned that the cold-plate with swirling structure has better heat transfer efficiency and smaller volume than most cold-plates sold in the market by using water as cooling-fluid. The conclusion and suggestion of the thesis instruct that it might lower the pressure drop and get better efficiency to reduce the number and increase the diameter of the swirling chambers. This research continues Y.P. Wang’s one to analyze the effect caused by changing the number of swirling chambers, the diameter of the swirling chambers, the thickness of the base, and the surface area of heat source. Firstly, this thesis reviews the papers about the swirling structure, and explains the correlative theories. Secondly, the thesis accounts for the calculation of the thermal resistance and overall heat transfer coefficient and also explain the theories about numerical simulation. The process and the setting of the numerical simulation are also explained, and then results of the numerical simulation are discussed. Finally, the best case is chosen to be deeply analyzed by using different flow rate.
