The Heating elements commonly used in drying industry
1. PTC heating element
PTC thermistor thermostatic heating PTC thermistor has thermostatic heating characteristics, its principle is that PTC thermistor charged after the self-heating temperature makes the resistance value into the jump zone, the surface temperature of PTC thermistor thermostatic heating will keep a constant value, the temperature is only related to the temperature inside the PTC thermistor and the applied voltage, and basically has nothing to do with the environmental temperature.
Application: electric mosquito repellent, hand warmer, dryer, electric plate, ironing pan, electric iron, electric gluer, curling iron, hand warmer, foot warmer, hand dryer, small warm air heater, hair dryer, greenhouse, dryer, dry wardrobe, clothes dryer, industrial drying equipment, electric dryer, electric oven, electric oven.
2. Electric heating wire
The working principle of electric heating wire is the same as that of other metal heating elements, which is the electric heating phenomenon after metal electrification. Electric heating means that after an electric current passes through a conductor, the current will produce a certain amount of heat and be transferred out by the conductor. The electric heating wire itself is a metal conductor, which will give off heat and provide heat energy after being electrified
