Ⅰ What is PTC Heater
PTC Heater is called PTC heating body, using PTC ceramic heating elements and aluminum tube composition. This type of PTC heater has the advantages of low thermal resistance and high heat transfer efficiency. It is an automatic thermostatic and power saving electric heater. The outstanding characteristic lies in the safety performance, any application will not produce such as electric heating pipe heater surface “red” phenomenon, resulting in Scald, fire and other safety hazards.
The utility model is composed of a zinc-plated outer pressure plate, a stainless-steel corrugated spring plate, a zinc-plated inner pressure plate, a single-layer aluminum radiator, a PTC heating plate, a double-layer aluminum radiator, a nickel-plated copper electrode terminal, and a pps high-temperature plastic electrode sheath. Due to the adoption of u-shaped corrugated heat sink, the heat dissipation rate of the product is improved, and the advantages of adhesive and mechanical type are integrated, and the various thermal and electrical phenomena of the PTC heat sink are fully taken into account Excellent thermal conductivity, heat dissipation, high efficiency, safe and reliable. This type of PTC heater has the advantages of low thermal resistance and high heat transfer efficiency. It is an automatic thermostatic and power saving electric heater. One of its outstanding features is its safety performance, that is, when the fan fails to turn over, the power of the PTC heater will automatically drop sharply due to insufficient heat dissipation At this point the surface temperature of the heater to maintain the Curie temperature (generally around 250 °C), so as not to produce such electric heating pipe type heater surface “red” phenomenon.
Ⅱ Principle of PTC Heater
The principle of constant temperature heating PTC thermistor is that the self-heating of PTC thermistor after heating makes the resistance value enter the jump zone, and the surface temperature of PTC thermistor will keep constant when heating at constant temperature The temperature is only related to the Curie temperature and applied voltage of PTC thermistor, but not to the ambient temperature PTC heater is a kind of heating device designed by constant temperature heating PTC thermistor. In the medium and small power heating occasions, PTC heater has many advantages over traditional heating elements, such as constant temperature heating, no open flame, high heat conversion rate, little influenced by power supply voltage, long natural life, etc. The application in an electric heating apparatus is more and more favored by R & D engineers. Constant temperature heating PTC thermistor can be made into a variety of shapes and different specifications, the common shape of a disc, rectangle, strip, ring, and honeycomb porous, etc. The combination of the PTC heating element and the metal member can form various forms of high-power PTC heater.
Ⅲ PTC heater is divided according to conduction mode
1. PTC ceramic heater based on heat conduction. The utility model is characterized in that a multi-layer heat transfer structure is arranged on the surface of the PTC heating element, including an electrode plate (electric conduction and heat transfer) insulating layer (electric insulation and heat transfer), a heat conducting and heat storing plate (some of which are also attached with heat conducting glue), etc. Transfer the heat from the PTC element to the heated object.
2. All kinds of PTC ceramic air heaters conduct convective heat transfer by the hot air formed. The utility model is characterized in that the output power is large and the air temperature and heat output can be automatically adjusted.
3. Infrared radiator. In practice, the far-infrared paint or far-infrared material contacting the surface of the PTC element or heat conducting plate can be directly or indirectly excited to radiate infrared ray by the heat emitted rapidly from the surface of the PTC element or heat conducting plate PTC ceramic infrared radiator.
Ⅳ PTC heater is divided according to the structure characteristics
1. General Utility type PTC ceramic heater. This type of appliance mainly includes electric mosquito repellent, hand warmer, dryer, electric hot plate, electric iron, electric adhesive, curling iron and so on. The utility model is characterized in that the power is small, but the thermal efficiency is high and practical.
2. Automatic constant temperature PTC heater. This kind of appliance mainly has a small crystal device constant temperature trough, constant temperature incubator, electronic thermos bottle, thermos box, Thermos Cup, Thermos Plate, thermos cabinet, Thermostable and so on. The utility model has the advantages of automatic heat preservation, simple structure, good constant temperature characteristic, high thermal efficiency, and wide temperature range.
3. Hot Air PTC heater. This kind of hot-air PTC heater mainly includes a small warm-air heater, hairdryer, greenhouse, dryer, clothes dryer, industrial drying equipment, etc… The utility model is characterized in that the output power of the hot air is large, the hot air is quick and safe, and the wind temperature and power consumption can be automatically adjusted.
Ⅴ the function of PTC IN AIR CONDITIONING
PTC ripple heater is a kind of self-control temperature heater.
1. The principle of constant temperature heating PTC thermistor is that the self-heating of PTC thermistor after heating makes the resistance value enter the jump zone, and the surface temperature of PTC thermistor will keep constant when heating at constant temperature The temperature is only related to the Curie temperature and applied voltage of PTC thermistor, but not to the ambient temperature.
2. PTC Heating Element is a heating element designed by using constant temperature heating PTC thermistor constant temperature heating characteristics. In the medium and small power heating occasions, PTC heating elements have the advantages that traditional heating elements such as constant temperature heating, no open flame, high heat conversion rate, minimal influence by power supply voltage, long natural life, etc. The application in an electric heating apparatus is more and more favored by R & D engineers.
3. Constant temperature heating PTC thermistor can be made into a variety of shapes and different specifications, the common shape of a disc, rectangle, strip, ring, and honeycomb porous, etc… The combination of the PTC heating element and the metal member can form various forms of high-power PTC heating element.
