Fireplaces, as a winter heating device and a cultural symbol, have entered ordinary households in large numbers. Since fireplace heating is a centralized method, an electric fan that can speed up air circulation is needed for indoor heating. Therefore, such electric fans dedicated to fireplaces that increase air circulation are increasingly entering homes and commercial places. This is a fan that uses thermal energy as an energy source to circulate the hot air generated by the wood-burning fireplace. There is a generator module on the heat powered stove fan, which acts as a small generator to drive the fan's motor. When this generator module experiences the difference in heat between the top and bottom surfaces, it generates current. The bottom of the heat powered stove fan heats the bottom surface of the module, while the top of the module is kept cool by the top heat sink of the fan.
