Structural characteristics and application of PTC heater
(1) Ordinary and practical PTC ceramic heater. Such appliances mainly include: electric mosquito repellent, hand warmer, dryer, electric heating plate, electric iron, electric soldering iron, electric heating adhesive, curling iron, etc. Its characteristic is that the power is not large, but the thermal efficiency is high and it is very practical.
(2) Automatic constant temperature PTC heater. Such appliances mainly include: small crystal device constant temperature bath, constant temperature incubator, electronic thermos bottle, incubator, thermos cup, insulation plate, insulation cabinet, insulation table, etc. It is characterized by automatic heat preservation, simple structure, good constant temperature characteristics, high thermal efficiency, and wide operating environment temperature range.
(3) Hot air PTC heater. Such hot air PTC heaters mainly include: small warm air heaters, hair dryers, heating rooms, dryers, drying wardrobes, clothes dryers, industrial drying equipment, etc. It is characterized by high output hot air power, rapid heating, safety, and automatic adjustment of air temperature and power consumption.
PTC’s role in air conditioning
The air conditioner PTC corrugated heater is a self-controlling temperature heater.
1. Constant temperature heating PTC thermistor has constant temperature heating characteristics. The principle is that after the PTC thermistor is powered on, the resistance value will enter the jump zone by self-heating. The surface temperature of the constant temperature heating PTC thermistor will maintain a constant value. It is related to the Curie temperature of the PTC thermistor and the applied voltage, but basically has nothing to do with the ambient temperature.
2. The PTC heating element is a heating element designed by using the constant temperature heating characteristic of the PTC thermistor. In the occasion of low and medium power heating, PTC heating element has the advantages of constant temperature heating, no open flame, high heat conversion rate, minimal influence of the power supply voltage, long natural life and other traditional heating elements. The application in electric heating appliances is becoming more and more popular. Favored by R&D engineers.
3. The constant temperature heating PTC thermistor can be made into a variety of shapes and structures and different specifications, the common ones are wafer shape, rectangle, strip shape, ring and honeycomb porous shape, etc. Combining the above-mentioned PTC heating elements and metal components can form various forms of high-power PTC heating elements.
