The combustion-supporting impeller rotates to provide oxygen, and the fuel burns in the burner to provide heat energy. The heat is conducted to the heat exchanger, and then conducted to radiators by means of the integrated graphite pad and the thermoelectric power generation modules, so that a temperature difference between the upper and lower surfaces of the thermoelectric power generation modules is generated; while the supply of heat energy is not affected, the thermoelectric power generation modules generate electricity, and the generated electricity will be sent to the power management system which distributes the power to the equipment and recharges the lithium battery pack to achieve the purpose of continuous work.

- 5. In the present invention, the power management system and lithium battery pack are used. When the equipment is working, the thermoelectric power generation modules will send power to the power management system, which will then send power to the electrical components and recharge the lithium battery pack by means of judgment and distribution.
