Thermal energy can be applied directly to heating, but also can be converted into mechanical energy or electric energy by thermal principle, and any form of thermal energy application needs to involve the transfer of thermal energy, and its transmission rate will affect the efficiency of energy utilization.

Heat exchangers are devices that remove heat from exhaust gases and convert heat to other applications as needed.

Heat pipe technology is to make full use of the principle of heat conduction and the rapid heat transfer properties of the refrigerant, heat transfer through the heat pipe heat quickly to the outside of the heat source, with fast average temperature characteristics.

Heat pipe technology is widely used in the early aerospace field, has been widely used in various types of heat exchangers, coolers, natural geothermal references, as fast heat conduction from the role of today's electronic cooling devices for the most common and efficient thermal components .
