Heating PTC thermistor has constant temperature heating characteristics, the principle is that PTC thermistor after power is turned on from heating to make the resistance value into the transition zone, constant temperature heating PTC thermistor surface temperature will remain constant,
Heating element piece designed by constant temperature heating PTC thermistor constant temperature heating characteristics. In the small and medium-power heating occasions, PTC heating elements have the advantages of constant temperature heating, long natural life, high thermal conversion rate, minimal influence by the power supply voltage, and their application in electric heating appliances is more and more favored by R&D engineers. Conventional heating elements are not up to the task.
Constant temperature heating PTC thermistors can be made into a variety of shape structures and different specifications, common are disc, square, bar, ring, PTC heating element and metal components can be combined to form various forms of high-power PTC heating elements.
Common practical PTC ceramic heating elements include: mosquito repellent, hand warmer, dryer, electric heating plate, electric iron, electric soldering iron, electric heat adhesive, curling hair perm. The power is not large, and the thermal efficiency is high.
Automatic thermostatic PTC heating elements include: small crystal device thermostatic tank, constant temperature incubator, electronic thermos flask, incubator, thermos cup, insulation plate, insulation cabinet, insulation table, etc. Automatic heat preservation, simple structure, good constant temperature characteristics, high thermal efficiency.
Hot air PTC heating elements include: small warm air heater, hair dryer, room warmer, dryer, drying wardrobe, dryer, industrial drying equipment, etc., output hot air power, fast heating, safety, can automatically adjust power consumption.
