The structure, function and welding process of electric heater

The duct type electric heater is different from ordinary electric heaters in terms of structure and function. Of course, its production will also have a series of strict requirements. In addition to understanding the basic composition of the duct type electric heater, we also To be familiar with its function and production process.

The air duct type electric heater is mainly composed of the main body and the control system. The heating element is made of stainless steel pipe as a protective sleeve, and a series of materials such as high temperature resistance alloy wire and crystalline magnesium oxide powder are placed inside, which are formed by a compression process. And its control part is composed of advanced digital circuits, integrated circuit triggers, high back pressure thyristors, etc., which realizes an adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater.

Because the air duct type electric heater is surrounded by corrugated stainless steel belt, the cooling area can be effectively increased, and the heat exchange efficiency is greatly improved. Moreover, the special design of the heater makes the wind resistance very small, maintains uniform heating, and does not have high cold corners.

The double protection design of the air duct electric heater makes the safety performance of the equipment during operation better; in addition, the thermostat and the fuse installed in the heater can be used to control the working temperature of the air duct, so that the duct electric heater is also The scope can be further expanded.

In the production of air duct type electric heater system, welding is a very important step, because most of the system is transported by pipelines, so the connection between the pipeline and the pipeline, the pipeline and other components, except for the bolt connection Welded.
