| Abstract |
An experimental study on the performance of a liquid electric component cooling system was performed. The thermal resistance and pressure drop at a heat sink were measured, for aluminum waterblocks with four different internal shapes, with either smooth surface, porous media filling, or with fins of 5 mm height, or of 7 mm height. The fins had 0.5 mm thickness, and the gap between the fins was 0.5 mm. The waterblock internal dimension was 36.5×36.5×7 mm. Compared with the waterblock with smooth surface, the thermal resistance reduction was 11%, 46%, and 42% for waterblocks with porous media filling, 5 mm, and 7 mm fins, respectively. A new dimensionless parameter was suggested to evaluate the waterblock performance, with the simultaneous consideration of thermal resistance and pressure drop. The performance of the waterblock with fins of 5 mm height was best by parameter. |
