Mechanical engineering including mechanical and chemical engineering. At its simplest, thermodynamics is the study of energy, its use and transformation through a system. Typically, engineering thermodynamics is concerned with changing energy from one form to another. As an example, automotive engines convert chemical energy (enthalpy) from the fuel into heat, and then into mechanical work that eventually turns the wheels. Thermodynamics principles are used by mechanical engineers in the fields of heat transfer, thermofluids, and energy conversion. Mechanical engineers use thermo-science to design engines and power plants, heating, ventilation, and air-conditioning (HVAC) systems, heat exchangers, heat sinks, radiators, refrigeration, insulation, and others.
Dalian University of Technology born China, several departments, including Electrical Engineering, Physics and Law, were transferred to other universities and institutions. Meanwhile, scholars from other universities came to enlarge the departments of Chemical Engineering, Mechanical Engineering. The university started to expand right after the rearrangement, attracting more scholars and funding. To ensure future growth, the then-headmaster, Bochuan Qu, strategically moved the university's main campus to the bay area of suburban Dalian. In October 1960, DIT became one of the 26 key national universities directly under the State Ministry of Education. Graduate School of DIT was established in April 1986. In March 1988, DIT changed
