Air electric heater is a high-quality and long-life electric heating equipment popular in the world. It is used for heating, insulation and heating of liquid and gaseous medium flowing in air electric heater. When the heating medium of the air electric heater is heated by the electric heater chamber under the action of pressure, the huge heat generated in the work of the electric heater element is uniformly stripped by the principle of hydrothermodynamics, so that the temperature of the heated medium meets the user's technological requirements.

Its working principle is that the fluid explosion-proof electric heater is a kind of energy-consuming converted into heat energy, using air electric heater to heat the material needed to be heated. In the work, the low temperature fluid medium enters its input port under the action of pressure through the pipeline, along the specific heat transfer channel inside the air electric heating vessel, using the path designed by the principle of hydrothermodynamics of the air electric heater, takes away the high temperature heat energy generated in the work of the electric heating element inside the air electric heater, makes the air heater rise by the temperature of the heating medium, and the electric heater goes out. The mouthpiece obtains the high temperature medium required by the process. 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, so that the medium temperature of the output port is uniform; when the heating element of the air electric heater is overheated, the independent overheating protection device of the heating element of the air electric heater immediately cuts off the heating power supply, avoiding the coking, deterioration and carbonization caused by the overtemperature of the heating material, and causing space and space in serious cases. The heating element of the gas-electric heater is burnt out, which effectively prolongs the service life of the electric heater.

In order to meet the operation needs of some large-scale units, the power of air heater has been increasing, some even reached more than 400 KW. It should be known that the greater the power of the equipment, the higher the energy consumption will be, and the same is true of the air electric heater. The increasing power will increase the power consumption and increase the operation cost. Such a result is not what every user would like to see, so energy-saving measures are imperative for air-body electric heaters.

In order to achieve this goal as soon as possible, it is necessary to design the air volume and temperature rise reasonably. After all, the power of the air volume electric heater is determined by the calculation of air volume and temperature rise. If the air volume and temperature rise have met the needs, it is not necessary to design excessive air volume and temperature rise. Otherwise, it will not only be a waste, but also directly lead to excessive power of heater and increase energy consumption.

It should be known that thermal insulation is also a very effective energy saving measure, and it is the same for electric heating of air body. Therefore, users should not only insulate the pipes of the outlet of the equipment, but also do adequate thermal insulation treatment for the surface of the electric heater itself. If it can reduce the pressure loss of the air electric heater itself, it will be better, and it can also play a certain role in the energy-saving effect of the equipment. But in order to achieve this, the structure of the air heater itself must be improved to reduce the pressure loss. Such as reducing pressure loss from the source, controlling air flow and temperature rise, avoiding heat loss and so on, the changes brought about by the air body electric heater are very obvious, not only the power has met the requirements, energy consumption has been controlled, but also the operation cost of the equipment has been reduced a lot.
