Ar duto tipo à prova de explosão elétrico aquecedor através ar alimentação sistema

The air duct explosion-proof electric heater uses a gas supply system to prevent the gas entering the explosion-proof air duct heater from forming high-temperature and high-pressure gases. The explosion-proof electric heater in the air duct evenly distributes the resistance wire in the high-temperature stainless steel seamless pipe, and compactly incorporates crystalline oxidation with good thermal conductivity and insulation performance in the air separation section. This structure is not only advanced, high in thermal efficiency, but also generates uniform heat. When there is current passing through the high-temperature resistance wire, the heat generated diffuses to the surface of the heating pipe through magnesium oxide powder. Transfer it again to the heated element or air to achieve the purpose of heating. The explosion-proof electric heater with air duct is used for industrial air ducts, air conditioning ducts, and various industries to heat the air and increase the outlet temperature. It is usually inserted through the horizontal opening of the air duct. According to the working temperature of the air duct, it can be divided into three types: low temperature, medium temperature, and high temperature. According to the wind speed of the air duct, it can be divided into low, medium, and high wind speeds.
The air duct explosion-proof electric heater is different from ordinary electric heaters in both structure and function. Of course, its manufacturing also has a series of strict requirements. In addition to understanding the basic composition of the air duct explosion-proof electric heater, we also need to be familiar with its functions and production process. Corrugated stainless steel strips are used around the air duct explosion-proof electric heater, which can effectively increase the cooling area and greatly improve heat exchange efficiency. And the specially designed heater reduces wind resistance, maintains uniform heating, and does not have excessively high cold angles. The heating body of the air duct explosion-proof electric heater uses stainless steel pipes as protective sleeves, with a series of materials such as high-temperature resistance gold wire and crystalline magnesium oxide powder embedded, which are compressed and formed. The control part is composed of digital circuits, integrated circuit triggers, high back voltage thyristors, etc., achieving an adjustable temperature measurement and constant temperature system to ensure the normal operation of the air duct explosion-proof electric heater.
