摘要

本研究通过比较和对比，评估了侧发散和均匀微通道散热器的热性能。采用 ANSYS Fluent 2017 代码进行计算流体动力学模拟，研究了这些微通道配置中的传热和流体流动特性。研究对象是雷诺数为 207 的微通道层流。目标是确定侧发散如何影响传统均匀微通道的散热效率。结果表明，最佳发散比为 1.5，可实现最高性能。研究还显示，侧发散微通道散热器的热性能比均匀微通道散热器高出 14%。

Comparative analysis of microchannel heat sinks for thermal performance enhancement

This study evaluated the thermal performance of side divergence and uniform micro-channel heat sinks by comparing and contrasting them. Heat transfer and fluid flow characteristics in these micro-channel configurations were studied using computational fluid dynamics simulations employing ANSYS Fluent 2017 code for this purpose. Laminar flow through micro-channels with a Reynolds number of 207 was the subject of the investigation. The goal is to determine how side divergence affects heat dissipation efficiency concerning traditional uniform micro-channels. The results showed that the best divergence ratio is 1.5 that achieved the highest performance. The study also revealed that side divergence micro-channel heat sinks can achieve thermal performance up to 14% higher than uniform micro-channel heat sinks.
