PTC heaters are divided by conduction method
(1) PTC ceramic heater based on heat conduction. Its characteristic is to pass through the electrode plate (electrical conductivity and heat transfer) of the PTC heating element surface device Thermal conductive glue) and other multi-layer heat transfer structures, which transfer the heat emitted by the PTC element to the heated object.
(2) Various PTC ceramic hot air heaters that stop convective heat transfer by the formed hot air. Its characteristics are large output power, and can automatically adjust the blowing air temperature and output heat.
(3) Infrared radiant heater. The characteristics of the PTC element or the rapid heat emitted by the surface of the heat-conducting plate directly or indirectly stimulates the far-infrared paint or far-infrared material that touches its outer surface to radiate infrared rays, which constitutes the PTC Ceramic infrared radiant heater.
PTC heaters are divided according to structural characteristics
(1) Ordinary applicable PTC ceramic heater. Such appliances mainly include: electric mosquito repellent, hand warmer, drier, 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 suitable.
(2) Automatic constant temperature type PTC heater. This kind of appliances mainly include: small crystal device constant temperature bath, constant temperature incubator, electronic thermos bottle, incubator, thermos cup, insulation tray, insulation cabinet, insulation table, etc. Its characteristics are automatic heat preservation, simple structure, good constant temperature characteristics, high thermal efficiency, and wide operating environment temperature range.
(3) Hot air PTC heaters. This type of hot air PTC heaters mainly include: small warm air heaters, hair dryers, heating rooms, dryers, drying wardrobes, clothes dryers, industrial drying equipment, etc. Its characteristic is output The hot air has high power, rapid heating, safe, and can automatically adjust the air temperature and power consumption.
