Car PTC heaters are divided by conduction method
(1) PTC ceramic heater based on heat conduction. Its characteristic is that the electrode plate (electrical conduction and heat transfer) and insulation layer (electrical insulation and heat transfer) are installed on the surface of the PTC fever element. Thermal conductive glue) and other multi-layer heat transfer layouts to transfer the heat emitted by the PTC element to the heated object.
(2) Various PTC ceramic hot air heaters that conduct convective heat transfer by the formed hot air. It is characterized by large output power and can automatically adjust the blowing wind to smoothly output heat.
(3) Infrared radiant heater. The characteristics of the actual use of the PTC element or the rapid heat emitted by the surface of the heat-conducting plate directly or indirectly triggers the far-infrared coating or far-infrared material that touches its surface to radiate infrared, which constitutes the PTC ceramic infrared Radiant heater.
Automobile PTC heaters are divided according to layout characteristics
(1) Ordinary applicable PTC ceramic heaters. This kind of appliances must include: electric mosquito repellent, hand warmer, desiccator, electric heating plate, electric iron, electric soldering iron, electric heating bonder, curling iron, etc. Its characteristic is that the power is not large, but the thermal compliance is high and it is very suitable.
(2) Automatic constant temperature type PTC heater. This kind of appliances must include: small crystal device constant temperature bath, constant temperature cultivation box, electronic thermos bottle, incubator, thermos cup, insulation tray, insulation cabinet, insulation table, etc. It is characterized by automatic heat preservation, simple layout, good constant temperature characteristics, high thermal compliance, and wide application temperature limitations.
(3) Hot-air PTC heaters. This type of hot-air PTC heaters are essential: small warm air heaters, hair dryers, room heaters, dryers, wardrobes, clothes dryers, industrial drying equipment, etc. Its characteristic is output The hot air has high power, rapid heating, safety, and can automatically adjust the power consumption of wind compliance.
Small size and high power: The heater mainly adopts clustered tubular electric heating elements. The heat response is fast, the temperature control accuracy is high, and the general heat obedience is high. High heating temperature: Heater plan-high mission temperature can reach 850℃. The medium outlet temperature is balanced, and the temperature control accuracy is high. Wide range of applications and strong adaptability: The heater can be used in explosion-proof or popular places. The explosion-proof grade can reach dⅡB and C grade, and the pressure resistance can reach 20MPa. Long life and high robustness: The heater is produced with extraordinary electric heating materials, the planned surface power load is low, and multiple protections are used to greatly increase the safety and life of the electric heater. Fully automatic control: according to the requirements of the heater circuit plan, the outlet temperature, flow, pressure and other parameters can be automatically controlled, and it can be connected to the computer. The consequences of energy saving are obvious. Almost 100-% of the heat generated by electric energy is transferred to the heating medium.
