Introduction to the main working principle of air heater

An air heater is a type of electrical energy that is converted into heat to heat an object to be heated. The main heating principle of air heaters is believed to be not very familiar. Today we mainly understand that when the air heater is working, the low-temperature fluid medium enters the input port under the pressure of the pipeline, and the specific heat exchange flow along the electric heating vessel. The path designed by the fluid thermodynamics principle of the air electric heater takes away the high-temperature heat energy generated by the electric heating element in the air electric heater, so that the temperature of the air electric heater is increased by the heating medium, and the electric heater outlet Get the high temperature medium required by the process.

The internal control system of the air heater automatically adjusts the output power of the electric heater according to the temperature sensor signal of the output port, so that the medium temperature of the output port of the air electric heater is uniform; when the heating element of the air electric heater is overheated, the heating element is The independent overheat protection device immediately cuts off the heating power source to avoid coking, deterioration and carbonization caused by overheating of the heating material in the air electric heater. In severe cases, the heating element in the air electric heater burns out, effectively extending the service life of the electric heater.
