| Constant temperature heating PTC thermistor PTC heating thermostat heating characteristics, since after the PTC thermistor is the principle of electric heat temperature jump value into the area, the surface of the constant temperature heating PTC thermistor temperature will remain constant, the temperature and PTC thermistor only related to the Curie temperature and applied voltage, and has nothing to do with the environment temperature basic. PTC heater is using constant temperature heating PTC thermistor temperature heating characteristics of heater. In small and medium-sized power heating conditions, the PTC heater with constant temperature high fever, the halogen-light, thermal conversion rate, little affected by the power supply voltage, long natural life incomparable advantage over traditional heating elements, such as in the application of electric appliance more and more get the favour of r&d engineers. Constant temperature heating PTC thermistor can be made into various shape structure and different specifications, common with wafer shape, rectangle, elongated, circles and honeycomb porous structure, etc. The above PTC heating elementParts and metal components are combined can form various forms of high-power PTC heater. PTC heater according to conductionType points (1) is given priority to with heat conduction of PTC ceramic heater. Its characteristic is installed on the surface of the PTC heating element electrode plates (conductive and heat insulation, electrical insulation and heat transfer) thermal heat storage plate (such as some additional heat conduction glue) multi-layer structure of heat transfer, the heat emitted by PTC element to the heated object. (2) with the formed by hot air convection heat transfer of PTC ceramic heat gun. Its characteristic is the output power is big, gentle wind out and can automatically adjust the output of heat. (3) infrared radiation heater. The characteristics of the actual use of PTC element or thermal conductive plate surface heat quickly, directly or indirectly, stimulate the contact with the far-infrared coating on the surface of the make it radiates infra-red or far-infrared materials, constitute the PTC ceramic infrared radiation heater. According to the structural characteristics of PTC heater points (1) general practical PTC ceramic heater. This type of equipment mainly include: electric mosquito mosquito dispeller, hand warmers, dryer, electric heating plate, electricityIron, electric, electric heat bonding machine, curl hair curler, etc. Its characteristic is the power is not big, but very practical high thermal efficiency. (2) type automatic constant temperature PTC heater. This kind of equipment mainly include: small crystal device thermostatic bath, constant temperature incubator, electronic vacuum flask, incubator, temperature, heat preservation plate, heat preservation tank, heat preservation table, etc. Characterized by automatic heat preservation, simple structure, good temperature characteristics, high thermal efficiency, using a wide temperature range. (3) the hot air PTC heater. This kind of hot PTC heater are: small low heaters, hair dryer, heating machine, dryer, dry wardrobe, clothes dryer, industrial drying equipment, etc. Its characteristic is hot air power output, heat speed, security, can automatically adjust the gentle wind power consumption. |
