However, since the surface area of the hot air balloon is large, the temperature inside the hot air balloon is lowered due to heat dissipation, and the hot air balloon falls due to insufficient buoyancy. The general heating methods include fuel combustion, electricity, solar energy, etc., wherein the fuel combustion is the most common and original method, which is simple and easy to implement, low in cost, and widely used. However, when the fuel is burned to heat the hot air balloon, hot air is supplied to the hot air balloon, and meanwhile, the residual heat gas in the hot air balloon has to be discharged, so that the gas can carry away the heat of the gas when leaving the hot air balloon, and the heat loss is increased. Therefore, more heat must be supplemented to ensure the normal operation of the hot air balloon; the hot air balloon which needs to operate for a long time also has to carry more fuel, which necessarily increases the weight of the hot air balloon, thereby limiting the staying time and the stroke of the hot air balloon in the air.
