A numerical analysis was performed to evaluate the hydrothermal performance of a pin-fin mini-channel heatsink (MCHS) with six different inlet/outlet flow arrangements from the first and second laws of thermodynamics point of views. The results are presented in terms of several important parameters such as convective heat transfer coefficient (h), CPU mean temperature (T_{m, CPU}), pumping power (${\dot{W}}_p$), frictional and thermal entropy generation rates (${\dot{S}}_{\mathit{fr}}$ and ${\dot{S}}_{\mathit{th}}$) as well as Performance Evaluation Criterion (PEC). The results demonstrated that configurations with two inlets and outlets have the lowest ${\dot{W}}_p$, ${\dot{S}}_{\mathit{fr}}$, h, and highest T_{m, CPU} among the studied cases. The vorticity intensification is high at the inlet/outlet headers and over the pin-fin bodies for the case with one inlet from the left and two outlets located at opposite sides, namely configuration d. The highest values of ${\dot{S}}_{\mathit{fr}}$ and h, the lowest value of T_{m, CPU}, and a moderate value of ${\dot{W}}_p$ are obtained for configuration d as compared to the other studied cases. In consequence, the maximum PECs (1.61–2.20) is obtained for case d at different Re numbers (500–2000). The PEC of configuration d is nearly 19.77% higher than those of configurations with two inlets and two outlets. Also, the PEC of configuration d is nearly 66.95% higher than those obtained for two other configurations with one inlet and two outlets.

进行数值分析以从热力学第一定律和第二定律的角度评估具有六种不同入口/出口流动布置的针翅式微型通道散热器 (MCHS) 的水热性能。结果以几个重要参数表示，例如对流传热系数 ( h )、CPU 平均温度 ( T _{m , CPU} )、泵功率 (${\dot{宽}}_{磷}$)、摩擦和热熵产生率 (${\dot{秒}}_{\mathit{fr}}$ 和 ${\dot{秒}}_{\mathit{日}}$) 以及绩效评估标准 (PEC)。结果表明，具有两个入口和出口的配置具有最低的${\dot{宽}}_{磷}$, ${\dot{秒}}_{\mathit{fr}}$, h , 和最高T _{m ,}研究案例中的_CPU。在入口/出口集管处和针翅体上方的涡量增强程度很高，因为一个入口在左侧，两个出口位于相对的两侧，即配置d。的最高值${\dot{秒}}_{\mathit{fr}}$和h，T _m的最低值_，CPU，以及中等的值${\dot{宽}}_{磷}$与其他研究案例相比，配置d获得了。因此，对于不同Re数 (500-2000) 的情况d，获得了最大 PEC (1.61-2.20 )。配置d的 PEC比具有两个入口和两个出口的配置高近 19.77%。此外，配置d的 PEC比具有一个入口和两个出口的其他两种配置的 PEC高出近 66.95%。
