Internal heat transfer of air heaters

Air heaters are high-quality, long-life electric heating devices used to heat, insulate, and heat flowing liquid and gaseous media. When the heating medium passes under pressure through the heater's heating chamber, it utilizes the principles of fluid thermodynamics to evenly dissipate the enormous heat generated by the heating element, bringing the heated medium's temperature to the user's process requirements.

The operating principle of a fluid explosion-proof electric heater is that it converts electrical energy into thermal energy, using the air heater to heat the material being heated. During operation, a low-temperature fluid enters the heater's inlet under pressure through a pipe. It then flows along a specific heat exchange path within the air heater's chamber, using the principles of fluid thermodynamics to dissipate the high-temperature heat generated by the heating element within the heater, raising the temperature of the heated medium and ensuring that the desired high-temperature medium is delivered to the heater's outlet. The internal control system of the electric heater automatically adjusts the output power of the electric heater according to the temperature sensor signal of the output port to make the temperature of the medium at the output port uniform; when the heating element of the air heater is overheated, the independent overheat protection device of the heating element of the air heater immediately cuts off the heating power supply to avoid coking, deterioration and carbonization caused by overheating of the heated material, which may cause the heating element of the air heater to burn out in severe cases, effectively extending the service life of the electric heater.
