摘要

本文讨论了第二定律在散热器设计中的应用。提出了一种新的基于熵的成本函数，并与现有的散热器成本函数进行了比较。一个板式翅片散热器的案例研究指出，这种新开发的成本函数提供的散热器的效率是传统的热阻最小化目标设计的散热器的两倍以上。考虑了这种新的散热器设计对数据中心冷却系统的影响，并发现它显着提高了系统效率和废热回收。

On the use of second law based cost functions in plate fin heat sink design

This paper discusses the use of the second law in heat sink design. A new entropy-based cost function is proposed and compared with existing heat sink cost functions. A case study of a plate fin heat sink points out that this newly developed cost function offers a heat sink which is more than twice as efficient as a heat sink designed with the traditional thermal resistance minimization objective. The effects of this new heat sink design on data center cooling systems are considered and found to be significantly improving the system efficiency and waste heat recovery.
