NF GROUP NFW15 DC600V 24KW High Voltage Coolant heater
Brief Introduction
This PTC electric heater is suitable for electric / hybrid / fuel cell vehicles and is mainly used as the main heat source for temperature regulation in the vehicle. The PTC electric heater is applicable to both vehicle driving mode and parking mode.
NFW15 is mainly used to heat the passenger compartment, defrost and demist the windows, or preheat the power battery thermal management battery, and meet the corresponding regulations and functional requirements.
The main functions of the high voltage coolant PTC heater are:
-Control function: the heater control mode is power control and temperature control;
-Heating function: convert electric energy into heat energy;
-Interface functions: energy input of heating module and control module, signal module input, grounding, water inlet and outlet.
The main performance features of the HVCH are as follows:
●With compact structure and high power density, it can flexibly adapt to the installation space of the
whole vehicle.
●The use of plastic shell can realize the thermal isolation between the shell and the frame, so as to
reduce the heat dissipation and improve the efficiency.
●Redundant sealing design can improve the reliability of the system.
