NF 8KW DC700V High Voltage Coolant heater
Description
1. Introduction
A Positive Temperature Coefficient (PTC) high-voltage heater is an electric heating device widely used in electric vehicles (EVs) and hybrid vehicles to provide efficient thermal management for both the cabin and battery systems.
Unlike traditional resistive heating elements, PTC materials exhibit self-regulating properties that automatically limit temperature rise, thereby preventing overheating and enhancing operational safety.
2. Application
The primary applications of PTC heaters include:
- **Cabin Heating**: Replaces the waste heat from internal combustion engines in EVs to ensure passenger comfort.
- **Battery Thermal Management**: Maintains optimal battery temperature to prevent performance degradation in cold conditions.
- **Fast Heating**: Delivers rapid and consistent warmth with high energy efficiency, minimizing the impact on vehicle range.
- **Safety**: Automatically reduces power output at elevated temperatures to eliminate the risk of component burnout.
Due to these advantages, PTC heaters are compact, highly reliable, and essential for the effective operation of electric vehicles in cold climates.
3. Function
The main functions of the NF GROUP integrated circuit water heating electric heater are as follows:
- **Control Function**: The heater supports both power control and temperature control modes.
- **Heating Function**: Converts electrical energy into thermal energy for heating purposes.
- **Interface Functions**: Includes connections for energy input, signal input, grounding, as well as water inlet and outlet ports for the heating module and control module.
