The PTC heater generates heat, the exterior is not live, and the fully sealed moisture-proof design is extremely safe. PTC is the abbreviation of Positive Temperature Coefficient, meaning a positive temperature coefficient, which generally refers to semiconductor materials or components with a large positive temperature coefficient. Usually we refer to PTC refers to the positive temperature coefficient thermistor, referred to as PTC thermistor. PTC thermistor is a typical temperature-sensitive semiconductor resistor. When it exceeds a certain temperature (Curie temperature), its resistance value increases stepwise with the increase of temperature.
1. Compared with the traditional heating element, the PTC heating element has the characteristics of automatic constant temperature. It does not require a temperature control system. The PTC heater body is used to heat the cold air. When the air is not supplied, the PTC heater will not damage the work reliably. PTC is used. Internal characteristics control temperature, never over-temperature,
2. When the PTC heater is used to heat liquid (such as water), after the liquid is dried, the PTC heating element will not be damaged. It has long-term electrical and thermal stability. Open flame, no oxygen consumption, gentle wind, not boring, safe and warm
Long service life under normal environment
3. Compared with the heating elements used in the market, it has the following advantages. The heating sheet is equipped with a fully-sealed moisture-proof design. Non-contact thermal resistance, higher efficiency. The surface is beautiful and novel. Under the same air outlet area, the power can be greater to meet the market demand in cold regions.
4. Insensitive to voltage fluctuations, wide application voltage range
5. The device is convenient and beautiful.
typical application:
1. Air heating, heater, air conditioning
