The course covers the followings contents: (1) the law of heat transfer; (2) three basic styles of heat transfer, i.e., thermal conduction, thermal convection and thermal radiation; (3) the basic theory and design method of heat exchanger; (4) experiment method of heat transfer. The course is structured to provide students with a basic ability to analyzing and treating with an actual engineering problem by using the basic theory and research method of heat and mass transfer, at the same time, a basis will be built for following relative courses.
