PTC air heater is a widely used electric vehicle heating system. This article will introduce the working principle and application of PTC air parking heater in detail. PTC is an abbreviation for "Positive Temperature Coefficient". It is a resistive material whose resistance increases with temperature. When current passes through the PTC material, the current will be converted into heat energy, thereby heating the PTC. PTC air heaters use this principle to heat the air inside the vehicle. PTC air heating consists of two main components: PTC material and fan. When electricity passes through the PTC material, it heats up and emits heat. The fan draws the air inside the vehicle, passes it through the PTC material, heats it up, and blows it out. In this way, the temperature inside the car will rise. The heating effect of PTC air heating is different from that of traditional heat exchangers. A traditional heat exchanger increases the temperature inside the vehicle by bringing the vehicle's coolant to the heater to heat it up and then circulate the hot air back into the vehicle. However, this method takes more time to achieve the desired interior temperature. In contrast, the PTC air heater can quickly heat the air in the car and does not require any external coolant. PTC air heating also has some other advantages. It doesn't need to be connected to the vehicle's engine, which means it can continue to heat the air inside the EV while it's parked. Also, it's very quiet, as it doesn't have any power components, so
there's no extra noise inside the vehicle. In conclusion, PTC air heater is an efficient and convenient electric vehicle heating system. It heats the air inside the car very quickly and doesn't require any external coolant. In addition, the PTC air heater is quiet and noiseless, and can continue to heat the air inside the vehicle even when it is parked, which is very suitable for electric vehicles.
