摘　　要：本文基于火积理论研究了热管中的热传输效率的优化问题。本文首先对比了传统熵理论和火积理论在分析传热效率方面的应用,然后详细介绍了火积理论,包括其物理意义和作为工程优化函数的应用。通过COMSOL仿真实验,本文展示了火积理论在热管设计优化中的实际应用,验证了理论的正确性,并对比了温差和火积耗散率与热管外径、芯层厚度等多个参数的关系,为热管等传热模型研究及生产设计优化提供了新视角。The article focuses on optimizing heat transfer efficiency in heat pipes using entransy theory.It begins by contrasting the application of traditional entropy theory and entransy theory in analyzing heat transfer efficiency.The paper then provides a detailed introduction to entransy theory,including its physical significance and application as an optimization function in engineering.Subsequently,through COMSOL simulation experiments,the practical application of entransy theory in optimizing heat pipe design is demonstrated,validating the theorys correctness.Relationship between the temperature difference and the entransy dissipation rate and a number of parameters,such as the outer diameter of the heat pipe and the thickness of the core layer,is compared.The article provides a new perspective for the study of heat transfer models,such as the heat pipe,and the optimization of the design of the production.
