传热学与电学问题的迁移类比研究:(1)理论基础

Analogy of transfer processes is an important and creative method in many interdisciplinary studies. Appropriate analogy of transfer processes facilitates the recognition and even the similar problem-solving between disciplines and further drives the development of interdisciplines. In this paper, we compare the development and connection of heat transfer and electrology. It is acknowledged that the mutual reference and learning of theories among disciplines can promote the development of heat transfer and electrology and verify the feasibility of thermal-electric analogy study. According to the fundamental theories of heat transfer and electrology, similarities and differences between heat transfer and electrology are analyzed in detail. It is found that there are similarities of the heat transfer and electrology in-between central physical quantities, derived quantities of central physical quantities, field functions and boundary conditions, and differences exist in some physical quantities, such as heat charge and charge, as well as the mechanism of heat transfer and conduction. Based on the antithetical relations of physical parameters between heat transfer and electrology, we obtain thermal circuit analysis model by the analogy investigation of electric circuit. This approach to the theoretical fundamentals on thermal-electrical analogy is expected to provide enlightenments for solving heat transfer problems in electrical engineering.
