10kw automotive coolant heater factory
HV PTC Heater, or High Voltage Positive Temperature Coefficient Heater, relies on the self-limiting temperature characteristics of PTC ceramic. In electric and hybrid vehicles, it handles cabin heating, defrosting, defogging, and battery thermal management, offering high efficiency and reliable safety.
Core Principles and Advantages:
Self-limiting temperature: As temperature rises, resistance increases sharply, automatically reducing current and power, preventing overheating without additional temperature control.
High efficiency and low loss: Electrical energy to heat conversion rate > 95%, rapid heating and quick response.
Safe and durable: No open flame, excellent insulation, withstands temperatures from -40℃ to +85℃, some models reach IP68.
Flexible control: Supports PWM/IGBT stepless power adjustment, compatible with CAN/LIN buses, facilitating vehicle integration.

Main Features
- High Efficiency: The immersion - type coolant resistance heater can reach an efficiency of about 98%, and its electro - thermal conversion efficiency is higher than that of traditional PTC heaters. For example, when the coolant flow rate is 10L/min, the efficiency of the resistance - wire heater can reach 96.5%, and as the flow rate increases, the efficiency will further increase.
- Fast Heating Speed: Compared with traditional PTC heaters, immersion - type coolant resistance heaters have a faster heating speed. Under the condition of the same input power and a coolant flow rate of 10L/min, the resistance - wire heater can heat up to the target temperature in only 60 seconds, while the traditional PTC heater takes 75 seconds.
- Precise Temperature Control: It can realize infinitely variable control of the heat output through the built - in control unit. For example, some electric coolant heater can control the heat output by regulating the water outlet temperature or limiting the maximum heat output or power consumption, and its control step can reach 1%.
- Compact Structure: The electric coolant heater is usually compact and lightweight, which is convenient for integration into the existing cooling system of the vehicle.
