The basic idea and principle of thermal circuit analysis method for heat transfer process were illustrated and the importance of this method in promoting students to understand heat transfer process and motivating students’ interest in learning was revealed. The results show that the thermal circuit analysis has clear physical meaning and is easy to understand. It not only can be used for heat conduction, convection, and radiation heat transfer analysis, but also can be applied in complex heat transfer process that coupled with heat conduction, convection and radiation heat transfer. It can be concluded that the thermal circuit analysis method should be emphasized in heat transfer teaching.
