PTC Heater Unit-7kw wireless beam version
PTC heater units are used in pure electric, hybrid, and fuel cell vehicles.
They mainly provide heat sources for in-vehicle air conditioning systems and battery heating systems.
The overall structure consists of radiators (including PTC heating packs), coolant flow channels, main Control board, high-voltage connector, low-voltage connector and upper shell, etc., can ensure the safe and stable operation of the PTC heater unit for vehicles, and the heating power is stable, the product heating efficiency is high, and the constant temperature is controlled.
Mainly used in hydrogen fuel cell systems and new energy vehicles.
