What is the main function and purpose of an electric heater?

Electric heaters are closely related to our lives. Next, let's learn about the main functions and uses of electric heaters.

According to the "2013-2017 China Electric Heater Industry Development Outlook and Transformation and Upgrading Analysis Report", the main functions and uses of electric heaters are as follows:

1, Heat treatment: local or overall quenching, annealing, tempering, and heat transfer of various metals;

2, Hot forming: whole piece forging, partial forging, hot heading, hot rolling;

3, Welding: brazing of various metal products, welding of various cutting tools and saw blades, welding of steel pipes and copper pipes, welding of the same and different types of metals;

4, Metal melting: (vacuum) melting, casting and evaporative coating of metals such as gold, silver, copper, iron, aluminum, etc;

5, Other applications of high-frequency heating machines: semiconductor single crystal growth, heat matching, bottle mouth heat sealing, toothpaste skin heat sealing, powder coating, metal implant plastics.

Fluid explosion-proof electric heater is a type of device that converts electrical energy into thermal energy to heat materials that need 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 electric heating container. The path designed using fluid thermodynamics principles takes away the high-temperature thermal energy generated during the operation of the electric heating element, causing the temperature of the heated medium 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 exceeds the temperature limit, the independent overheating protection device of the heating element immediately cuts off the heating power supply to avoid overheating of the heating material causing coking, deterioration, and carbonization. In severe cases, it can cause the heating element to burn out, effectively extending the service life of the electric heater.
