Advantages of alloy wire infrared heating tube heaters
1. Working principle
Alloy wire infrared heating tube heaters mainly work by heating alloy wires. Alloy wires (usually nickel-chromium alloys, etc.) have high resistivity. When current passes through the alloy wires, according to Joule’s law (where is heat, is current, is resistance, and is time), the alloy wires will generate a lot of heat.
The heated alloy wires increase the temperature of the tube wall of the heating tube, and then emit infrared rays outward in the form of thermal radiation. The wavelength range of infrared rays is between 0.76 – 1000\\u03bcm, most of which can be converted into thermal energy after being absorbed by objects, thereby achieving the function of heating. This method of heat radiation transmission does not require a medium and can directly transfer heat to surrounding objects and human bodies.
