Teaching Reform of"Heat Transfer"based on the Case of"Numerical Simulation of Battery Cooling System for New Energy Vehicles"
Heat transfer is a science that studies the heat transfer process,and has a wide range of applications in the field of engineering technology.However,the knowledge of heat transfer covers a wide range and there are many formulas,which is difficult for students with insufficient life experience and engineering background knowledge,resulting in insufficient learning motivation.In order to solve this problem,this paper relies on the common heat dissipation problems of power batteries for new energy vehicles in daily life to carry out the classroom teaching reform of heat transfer.This paper proposes a case-inspired teaching method reform,combined with the heat transfer process for theoretical analysis and modeling,through numerical calculation methods to simulate the heat transfer process,and establish timely feedback,so as to verify the students'learning results and form an interactive teaching.Based on the calculation results,the heat dissipation process of the power battery of new energy vehicles is visualized and the structure is designed to improve its heat transfer effect,and finally the effect of the design system is tested through experimental research.Through the above process,students can better grasp the basic concepts,principles and methods of heat transfer,which provides a good case for understanding the connotation of heat transfer theories such as heat conduction and convective heat transfer and their application in engineering,avoiding the traditional teaching method of cramming,and significantly improving the teaching effect.
