Internal heat transfer of air electric heater

Internal heat transfer of air electric heater

Air electric heater is a high-quality and long-life electric heating equipment used for heating, insulation, and heating of flowing liquid and gaseous media in air electric heaters. When the heating medium of the air heater passes through the heating chamber of the electric heater under pressure, the huge heat generated during the operation of the electric heating element is uniformly carried away using the principle of fluid thermodynamics, so that the temperature of the heated medium meets the user's process requirements.

The working principle is that the fluid explosion-proof electric heater is a type of electric heater that converts electrical energy into thermal energy and uses an air electric heater to heat the materials to be heated. In work, low-temperature fluid medium enters its input port through a pipeline under pressure, and follows a specific heat exchange channel inside the air heating container. The path is designed using the fluid thermodynamics principle of the air heater, taking away the high-temperature thermal energy generated by the electric heating element inside the air heater during operation, causing the temperature of the heated medium in the air electric heater to rise, and the outlet of the electric heater 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 based on the temperature sensor signal at the output port, so that the medium temperature at the output port is uniform; When the heating element of the air heater exceeds the temperature limit, the independent overheating protection device of the heating element of the air heater immediately cuts off the heating power supply, avoiding overheating of the heating material that may cause coking, deterioration, and carbonization. In severe cases, it may cause the heating element of the air electric heater to burn out, effectively extending the service life of the electric heater.

Structure of circulating air duct heater:

1. The circulating air duct heater uses stainless steel heating tubes as the heating element;

2. The circulating air duct heater is supported by carbon steel or stainless steel materials;

3. The circulating air duct heater is composed of a combination connection method.

Characteristics of circulating air duct heater:

1. The circulating air duct heater adopts an externally wound corrugated stainless steel strip, greatly improving the heat exchange efficiency;

2. The design of the circulating air duct heater is reasonable, with low wind resistance and uniform heating;

3. A temperature controller and fuse are installed on the circulating air duct heater, which can be used to control the operation of the circulating air duct heater in case of air temperature exceeding the limit, ensuring that there is no risk.
