NF Electric Vehicle 3.5KW PTC Air Heater 333V PTC Heater

Short Description:

The motor waste heat of pure electric vehicles cannot meet the needs of winter heating, so winter heating is a problem that pure electric vehicles need to solve. Positive temperature coefficient heaters (positive temperature coefficient, PTC) are composed of PTC ceramic heating elements and aluminum tubes, which have the advantages of small thermal resistance and high heat transfer efficiency, and are less modified on the basis of fuel vehicles.
