The cooling capability of heat sinks is important for a central processing unit (CPU). In this work, simulation has been done to investigate heat transfer (HT) in a heat sink (HS) mounted on the circular cylinder chip of a CPU that is studied and to explore the thermofluid behavior of the designed micro-pin-fin heat sink (MPFHS). Air cooling methods are used for heat extraction. This numerical work considers the effects of inlet turbulence intensity (TI) and fin diameter (D) of the micro-pin-fin on the performance of the HS. Turbulent SST model is used to explore turbulence regime in the system. The HT and pressure coefficient were obtained at different Reynolds number (Re) (i.e., different inlet velocities). As shown in this study, the Nusselt number (Nu) rises with the increase in air flow velocity which enhances the heat extraction from CPU.

散热器的冷却能力对于中央处理器（CPU）至关重要。在这项工作中，已经进行了仿真，以研究安装在正在研究的CPU的圆柱体芯片上的散热器（HS）中的传热（HT），并探索所设计的微针鳍式散热器的热流体行为。 （MPFHS）。空气冷却方法用于热量提取。该数值研究考虑了入口湍流强度（TI）和翅片直径（D）的微针鳍对HS的性能。湍流SST模型用于探索系统中的湍流状态。在不同的雷诺数（Re）（即不同的入口速度）下获得HT和压力系数。如本研究所示，Nusselt数（Nu）随着气流速度的增加而增加，从而增强了CPU的散热能力。
