High Voltage Coolant Heater

 

 

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 applies to both vehicle driving mode and parking mode.

 

In the heating process, electric energy is effectively converted into heat energy by PTC components. Therefore, this product has faster heating effect than an internal combustion engine. At the same time, it can also be used for battery temperature regulation (heating to working temperature) and fuel cell starting load.

 

The PTC electric heater adopts PTC technology to meet the safety requirements of passenger cars for high voltage. In addition, it can also meet the relevant environmental requirements of components in the engine compartment. The purpose of PTC electric heater in application is to replace the engine block as the main source of heat source. By supplying power to the PTC heating group, the PTC heating component is heated, and the medium in the circulating pipeline of the heating system is heated through heat exchange.

The basic principle of water heating PTC is the thermal effect of electric current, i.e., heat is generated when electric current flows through a conductor. Electrons overcome resistance while flowing through the conductor, performing work and generating heat. By heating the liquid flowing through the PTC, the vehicle's heating function is achieved.

 

1. Heat Exchange Efficiency: Product heat exchange efficiency >95%

2. Lifespan: >20,000 hours, with product performance deviation <10%

3. Reliability: Power and surge current deviation <10% over the product's lifespan

4. Insulation Performance: >100 MΩ at DC 1000 V/60 seconds

5. Higher Thermal Efficiency: The installation housing is made of plastic, resulting in low thermal dissipation

6. Low Water Resistance: Low water resistance reduces pressure loss

 

1. Unique flow channel design structure increases heat exchange area, reduces flow resistance, and improves heat exchange efficiency;

2. Multi-group heating branch design effectively reduces surge current and enables stepwise power regulation;

3. Integrated intelligent temperature control module (e.g., CAN communication) and multiple safety protections (overheating, overcurrent, water-electric separation);

4. Fully plastic housing design for safety and reliability;

5. Modular design for quick customization according to vehicle requirements;

 

 

New energy vehicle electric heaters can be used in the following systems to improve driving comfort and ensure vehicle performance.

 

Power battery system: The power battery heater is used to maintain the appropriate operating temperature of the power battery, especially in low-temperature environments. It can preheat the battery and improve its performance and life.

 

Heating system: Electric heaters can be used in car heating systems to provide interior heating by heating circulating fluid to keep the cockpit warm and comfortable.

 

Air conditioning system: In the air conditioning system, electric heaters can be used to heat the air, providing additional heating effects and increasing driving comfort.

 

Seat heating system: Electric heating film can be applied to seats to heat seats, providing driver and passenger seat heating functions to increase driving comfort.

 

Defrost system: Electric defroster can be applied to the glass, rearview mirror and other parts of the vehicle to remove frost or ice and snow to ensure driving safety and improve vision clarity.

 

Cooling system: Some electric heaters can also be used in the vehicle's cooling system to prevent the coolant from freezing or overcooling in low-temperature environments and protect the normal operation of the engine and electric system.
