| Abstract: | The thermo-Performance of new-style drive heat sink was investigated. The numerical method dealt with the 3-dimesional velocity field and temperature field of the heat sink was proposed based on the micro-element time-varied coefficient of convective heat transfer. The 3-dimesional temperature fields of the heat sink were analyzed and calculated. The results compared with the experimental values and numerical ones indicate the method solving the heat sink performance based on the method is more accurate than the method based on the average thermo-boundary coefficient of convective heat transfer. The performance of heat sink will be observably improved by optimizing its structure. |
