Aiming at the practical problems in the traditional thermal course after the National Engineering Education Accreditation in mechanical engineering, the trinity of thermal curriculum system of fundamental theory-professional application-thermal technology for the education management has been constructed, which is based on the present statue and corresponding reform initiatives in thermal curriculum system at home and abroad. Furthermore, the corresponding applicable documents for the education management, which include topic content, evaluation index and assessment, have been presented. It provides the basis for the teaching and management of thermal mechanical engineering technology course.
