Abstract

Abstract This research studies a three-dimensional fluid flow, and heat transfer in the heat sink numerically using air as a coolant. The numerical effects of the number of fins and their thickness on the performance of the heat sink are investigated using Ansys Icepak. Various fin numbers and fin thicknesses are used to check the heat sink’s optimal thermal performance. The results demonstrated that the maximum temperature, pressure drop, and thermal resistance decrease with the increase in the fin number and thickness. According to the results, the optimal thickness and number of fins for the current study are 15 and 0.25 mm, respectively. Also, it is observed that increasing the number of fins has a greater effect than increasing the thickness of the fins on the maximum temperature, pressure drop, and thermal resistance.

使用Ansys Icepak对翅片散热器中流体流动和传热的数值研究

摘要本文对以空气为冷却剂的三维流体流动和散热器内的传热进行了数值研究。利用Ansys Icepak软件，研究了散热片数量和厚度对散热片性能的影响。使用不同的翅片数和翅片厚度来检查散热器的最佳热性能。结果表明，随着翅片数量和厚度的增加，最高温度、压降和热阻均减小。根据研究结果，本研究的最佳翅片厚度和数量分别为15 mm和0.25 mm。此外，增加翅片的数量比增加翅片的厚度对最高温度、压降和热阻的影响更大。
