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.
Abstract
The article focuses on optimizing heat transfer efficiency in heat pipes using entran-sy 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 appli-cation of entransy theory in optimizing heat pipe design is demonstrated,validating the theory's correctness.Relationship between the temperature difference and the entransy dissi-pation 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 pro-duction.
