The U-shaped heating element is an electric heating component with a stainless steel or carbon steel shell, internally filled with magnesium oxide insulation material and wound with electric heating alloy wires (such as nickel-chromium or iron-chromium alloy). Both ends feature a silicone sealing and threaded fastening structure, with metal heat dissipation fins wound around the surface to expand the heat dissipation area, which can reach 2.5-4 times that of ordinary bare tubes.
Structural Features
The U-shaped heating element adopts a U-shaped tubular design, reducing its own heat loss, enabling faster heating and higher thermal efficiency at the same power. It supports customized production to meet various power and shape requirements (such as U-shaped, ring-shaped, etc.).
Application Scenarios
Widely used in mechanical manufacturing, automotive industry, textile spraying equipment, power equipment moisture protection, and other fields for static air heating and equipment moisture prevention. Examples include dehumidification heating in switchgear and ring main units, as well as material heating in industrial storage tanks.
Performance Advantages
Efficient Heat Dissipation: Surface heat load is increased by 2-3 times, reducing equipment size.
Safety Design: Some models support PID temperature control and over-temperature interlock protection to ensure stable operation.
