DISCUSSION ON THE OPTIMIZATION OF HEAT PIPE HEAT TRANSFER EFFICIENCY BASED ON ENTRANSY THEORY

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 theory's 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.
