Recent Development in Optimization of Flow and Heat Transfer Performance for Microchannel Heat Sinks

In the current era of rapid technological development, microchannel heat sink technology has attracted significant attention due to its remarkable advantages in fluid flow and heat transfer performance. This paper aims to explore optimization methods for the flow and heat transfer performance of microchannel heat sinks (MCHS) by reviewing and summarizing various innovative structural designs, with the goal of achieving breakthrough progress in heat transfer efficiency. First, the paper reviews the fundamental principles and the current research status of MCHS, emphasizing their potential applications in efficient heat transfer. Next, several strategies to optimize the flow and heat transfer performance of MCHS are presented in detail, including modifications to channel cross-sections and manifold design. Through a review of relevant literature, comparison of experimental data, and numerical simulation analysis, the effectiveness of these optimization strategies is validated. Finally, the main challenges currently faced in the research are summarized, and the future development direction is discussed. This paper not only provides a systematic guide for beginners but also offers new ideas and methods for further research in this field.
