The arc-shaped shell plate 1-3 and the heat dissipation fins 1-4 are made of stainless steel or aluminum or copper. The arc-shaped shell plate 1-3 mainly dissipates heat to the room through radiation and convection. The outer side and the heat dissipation fins 1-4 are sprayed with heat dissipation paint to strengthen the heat dissipation and reduce the temperature of the arc shell plate 1-3. By adopting the heat dissipation fins 1-4, the heat exchange area can be increased several times, and the temperature of the arc-shaped shell plate 1-3 can be significantly reduced.

The bottom plate 1-1 of the asbestos pad is arc-shaped and fixed on the first folded edge 1-2-1 of the arc-shaped inner shell plate 1-2 and the second folded edge 1-3-1 of the arc-shaped outer shell plate 1-3 by screws Above, the asbestos pad bottom plate 1-1, the arc-shaped inner shell plate 1-2 and the arc-shaped outer shell plate 1-3 form a thermoelectric power generation chip installation cavity I, and the width of the side 1-2-3 is smaller than that of the arc-shaped inner shell plate 1-3. 2 and the distance between the arc-shaped outer shell plate 1-3, the arc-shaped inner shell plate 1-2 and the arc-shaped outer shell plate 1-3 are not in direct contact.

Five thermoelectric power generation sheets 3 are evenly arranged and installed in the thermoelectric power generation sheet installation cavity 1 on the outer casing 1. The hot end of the thermoelectric power generation sheet 3 is located on the side of the arc inner shell plate 1-2, and the cold end of the thermoelectric power generation sheet 3 is located in the arc On one side of the outer shell plate 1-3, between the two adjacent thermoelectric generation sheets 3 and the two ends of the five thermoelectric generation sheets 3 and the sides 1-2-3 of the arc-shaped inner shell plate 1-2 Filled with adiabatic adhesive 4, thermally conductive silicone grease 5 is filled between the thermoelectric power generation sheet 3 and the inner wall of the thermoelectric power generation sheet installation cavity 1, and the thermoelectric power generation sheets 3 are connected in series by wires and then connected to the voltage-stabilizing charging module (not shown in the figure). shown) with plug-type wiring for electrical connection.

The asbestos pad cover plate 2 is arc-shaped, and is installed on the casing 1 by screws, and the thermoelectric power generation sheet 3 is enclosed in the thermoelectric power generation sheet installation cavity 1 by the asbestos cover plate 2.

The working principle of the utility model is as follows: when the gas stove is ignited, the heat of the flame is mainly transmitted from the flame to the arc-shaped inner shell plate 1-2 in the form of radiation, and is transmitted from the arc-shaped inner shell plate 1-2 through the thermal conductive silicone grease 5 to the arc-shaped inner shell plate 1-2. The hot end of the thermoelectric power generation sheet 3, and then the heat is transferred from the hot end of the thermoelectric power generation sheet group 3 to the cold end, and the cold end of the thermoelectric power generation sheet group 3 is transferred to the arc-shaped shell plate 1-3 through the thermal grease 5, and finally the arc-shaped Shell panels 1-3 transfer heat to the environment by radiation and natural convection.

The Seebeck effect is a thermoelectric phenomenon in which the voltage difference between two substances is caused by the temperature difference between two different electrical conductors or semiconductors. According to Fourier's law of heat conduction, since the thermoelectric power generation sheet 3 in the device has a large thermal resistance, and a sufficient temperature difference is formed between the hot end and the cold end of the thermoelectric power generation sheet 3, according to the Seebeck effect, the thermoelectric power generation sheet 3 Part of the heat energy can be converted into electrical energy, which is processed by the voltage-stabilizing charging module, and provides ignition power for gas stoves or power for kitchen lighting.
