Finned electric heating tube (radiator electric heating tube) is made of high-quality stainless steel, high-temperature magnesium oxide powder, electric heating alloy wire, metal heat sink and other materials. Through advanced production equipment and processes, the fins are wound on the outer surface of the heating tube, with strict quality management. Compared with ordinary elements, the heat dissipation area of the finned electric heating tube is expanded by 2 to 3 times, that is, the surface power load allowed by the finned element is 3 to 4 times that of the ordinary element. Due to the shortened length of the heating element, its own heat loss is greatly reduced. Under the same power conditions, it has the advantages of fast heating, uniform heating, good heat dissipation performance, high thermal efficiency, long service life, small heating device volume, and low cost. Reasonable design is carried out according to user requirements for easy installation. This series of products can be installed in air blowing ducts or other static or flowing air heating occasions, and are widely used in machinery manufacturing, automotive, textile, food, home appliances and other industries, especially in the air conditioner air curtain industry.
Finned electric heating tube refers to winding metal heat sinks on the basis of U-shaped heating tubes, expanding the heat dissipation area through the heat sinks, thereby accelerating heat dissipation. U-shaped finned electric heating tube is made of high-quality stainless steel, modified magnesium oxide powder, high-resistance electric heating alloy wire, stainless steel heat sink and other materials. It is suitable for heating air or spaces in ovens, drying channels, machinery manufacturing, automotive, textile, food, home appliances and other places.
Design and customization of finned electric heating tube
Prerequisites for design and customization: U-shaped finned electric heating tube is generally used in air dry burning working environment. Before customizing the design, the customer needs to inform the specific working environment size, whether there is a temperature control device, and if so, what is the controlled temperature? At the same time, it is necessary to inform whether there is a fan circulation device and the installation space size!
