ptc refers to semiconductor materials or components with very large temperature coefficients. With the development of technology, ptc can once be used in automobiles. We call this kind of ptc used in automobiles as the new power automobile ptc, in order to make everyone better Applying the new power car ptc, we will introduce the characteristics of the car PTC heater.
Features of automotive PTC heaters:
1 Automobile PTC heater has voltage withstand function, the heater's very high withstand voltage can reach more than 1300VDC, ensuring the reliability of always working under high voltage;
2 The temperature rises rapidly at low temperatures, even if the temperature reaches -40 degrees, it can start quickly;
3 Has a small intrusion current and glitch current;
4 The characteristics of the automobile PTC heater, the new power automobile ptc adopts a weird patented layout plan, has a very small leakage current, and ensures the safety function of the heater;
5 The power aging of the new power car ptc is extremely small under high DC voltage, and it can still maintain a good heating effect after permanent application;
6 The surface temperature of the ptc of the new power vehicle (when the wind is low) can be adjusted arbitrarily according to customer requirements, limited to 140 degrees-250 degrees;
7 The application life is more than 10 years.
When the heating plate of the PTC heater of the new power automobile is used to heat the liquid (such as water), the heating plate of the PTC heater of the new power automobile will not be damaged after the liquid is dried. If the PTC heater heating plate of the new power vehicle is used to heat the cold air, the PTC heater heating plate of the new power vehicle will not be damaged under the condition of not requiring air supply, and the application life is long. Under normal conditions, the service life can reach More than ten years.
The PTC heater heating plate of the new power vehicle works reliably. It uses the characteristics of the PTC heating plate to perform temperature control, and there will never be over-temperature signs. The working voltage is very wide: when the working voltage is changed twice, the surface temperature changes very little.
When multiple new power vehicle PTC heater heaters are used at the same time, they should be used in parallel, not in series. Different heat dissipation conditions make the fever power of PTC heaters very different.
The fever power of the PTC heater heating film of the new power car changes from large to small after the power is turned on, and it is consolidated after the emergency. The stable power is related to the application premise. Similar to the PTC fever, the stable performance may be several times different for different application premises. The faster the heat transfer rate, the greater the consolidation power; the higher the surface temperature, the greater the consolidation power.
