Detailed ways

Referring to Figures 1 to 4, a waste heat power generation type gas heater includes a burner 20, an electrical device and a rechargeable battery 37 for powering the electrical device, and a thermoelectric power generation chip is provided below the burner 20 31. The output end of the thermoelectric power generation chip 31 is electrically connected to the battery 37. The hot end of the thermoelectric power generation chip 31 conducts heat with the burner 20 through a heat conduction block 32. The cold end of the thermoelectric power generation chip 31 is closely attached to a heat sink 34. The heat conduction block 32 can absorb the waste heat of the burner and conduct it to the hot end of the thermoelectric power generation chip 31, and the cooling device 34 can cool the cold end of the thermoelectric power generation chip 31, forming a temperature difference between the cold end and the hot end of the thermoelectric power generation chip 31 , make it generate electric energy and send the electric energy to the battery 37 for use by the electric device, prolong the service time of the battery 37, do not need to replace the battery 37 frequently, and make full use of the waste heat of the burner 20 for power generation, energy saving and environmental protection . The hot end of the thermoelectric power generation chip 31 can also adopt other methods such as heat pipes to absorb the heat generated by the burner 20 when it works, and the thermoelectric power generation chip 31 can also be made into a strip shape to increase the distance between the hot end and the cold end, so that The hot end can be brought directly close to the burner 20 to absorb heat.

In this embodiment, the heat dissipation device 34 is a heat dissipation water tank. Liquid coolant can be added in the heat dissipation water tank, which can absorb more heat. After using the heater for a long time, it can still play a cooling role, and keep the cold end of the thermoelectric power generation chip 31 and the heat. The temperature difference between the terminals enables the thermoelectric power generation chip 31 to continuously generate power, which can meet the power consumption demand of the power consumption device. Certainly, the heat dissipation device 34 may also adopt other commonly used structures such as fin radiators and fans.

One end of the heat conduction block 32 is close to the hot end of the thermoelectric power generation chip 31 , and the other end extends to the burning place of the burner 20 . When in use, the heat conduction block 32 is directly heated by the flame and then conducts heat to the hot end of the thermoelectric power generation chip 31 to maintain a higher temperature, increase the temperature difference between the cold end and the hot end, and improve power generation efficiency.

The bottom of the cooling water tank is provided with cooling fins 33, which further improves the heat dissipation efficiency; one group of opposite sides of the cooling water tank is respectively provided with a water injection port 35 and a water outlet 36, which is convenient to add or replace cooling liquid in the cooling water tank 34, and also can increase a cooling liquid.
