Abstract: | A compact thermal model was established to model thermal characterization of a microchannel cold plate for high temperature uniformity in multiple heat sources. Analytical calculation of the compact model was presented. Experiments were also conducted to validate the model. The comparison reveals that the measured temperatures are close to the ones predicted by the compact thermal model. The cold plate can help multiple heat sources achieve high temperature uniformity, and the maximum temperature difference among the heat sources is 1.3 °C in the present experimental cases. Moreover, a straight minichannel cold plate was designed and tested under the same flow rate. The measured results show that there exists relatively large temperature gap among the heat sources, and the maximum value is 6.7 °C. |
