Resistance wire is the core part of electric heater element, electric heating element without resistance wire will lose the heating function. Since the resistance wire is so important, what material is used for the resistance wire , and how much wire diameter will affect the service life of the electric heater? Let's talk about what is the factors influence the diameter of the resistance wire ?
Before making an electric heating element, we must know: shape, pipe diameter, size, voltage, power and working environment. The voltage and power are the necessary parameters to determine the size of the resistance wire used in the electric heater element.
If you want to know how big the diameter of the resistance wire is, you need to first find out the resistance value according to the voltage and work, and you can find out the resistance value with voltage * voltage/power. At this point, the resistance value of the tube is established.
We all know that there are two types of resistance wire for the heater element normally, one is the outer winding wire, that is, the electric heating wire is wound on the magnesium rod. The other is directly into the spring shape, and then inserted into the electric heating element inside.
But no matter what's the type of wire, its wire diameter is determined by resistance value, pipe diameter, length (heating zone length).
