碩士 / 國立交通大學 / 機械工程系所 / 103 / In typical applications of electronic cooling, keeping the volume of the cooling module as small as possible is a must due to space confinement; however, as the volume gets smaller, the accommodated area required for heat transfer also suffers appreciably. In the cases where raising the effective heat transfer area is constrained, based on the Newton’s cooling law, to maintain the same heat transfer rate without raising the heat transfer area, we need to raise the heat transfer coefficient, effective temperature difference or both.
The present study proposed a V-shaped cannelure structure applicable for electronic cooling thermal module. The proposed modified thermal module can appreciably reduce the heat sink volume (up to 30%) and still maintain a lower base temperature than the original plain fin design. Based on the foregoing discussions, the following conclusions are made. In summary of the experiment, the redesigned V-shaped cannelure structure thermal module is able to maintain the same performance (even better) as plain fin thermal module when the heat sink volume is reduced by 30% and also able to lower the pressure drop by about 40%.
