| Abstract: |
| Objective To Sstudy the effects of fin width and thickness on the performance of tube-plate heat sink. Methods Fluent module in Ansys was used to simulate the heat transfer performance of tube-plate heat sink fin with different width and thickness of tube-plate heat sink fin, and analyze the effects of fin width and thickness on the temperature uniformity of tube-plate heat sink were analyzed. Results It shows that tThe narrower the fin, the better the temperature uniformity of heat sink, and the closer the average temperature of the fin wais to the temperature of the coolant.. Increasing the fin thickness can enhance heat transfer, but increase the heat sink weight and manufacturing cost will also increase, and . When it is was increased to a certain value, the heat transfer effect would not beis not enhanced significantly. Conclusion The width and thickness of the heat sink fin have a great influences on the temperature uniformity of the heat sink. The thicker the fin, the narrower the width, and the better the temperature uniformity of the heat sink. However, the uniformity of heat sink temperature cannot be improved by simply increasing the thinchnessthickness and reducing the width. When designing the heat sink, it is necessary to combine the other factors to select the fin width and thickness. |
