Specification:

 
 
 

 
The EVLINK high-voltage coolant heater is an electric heating device used in vehicles to heat circulating coolant through the cabin heating system. It is particularly suitable for electric, hybrid, and hydrogen-powered vehicles. In cold weather conditions, traditional heating systems that rely on engine waste heat become less reliable in these new energy vehicles, whereas high-voltage coolant heaters provide efficient heating.
 

 
 
Market Growth Drivers
The high-voltage coolant heater market is expected to experience significant growth in the coming years, driven by several key factors:
 
Increased Demand for Electric and Hybrid Vehicles: As electric vehicles become more popular, the demand for efficient and reliable heating systems is also increasing.
 
 
Strict Government Emission Regulations: Stringent regulations on vehicle emissions by various governments are further promoting the use of electric and hybrid vehicles, thereby driving the demand for high-voltage coolant heaters. Compared to traditional heating systems, high-voltage electric heaters offer better energy efficiency.
 
 
Technological Advancements in Commercial Electric Vehicles: EVLINK provides advanced heater technology for electric buses, trucks, industrial vehicles, and more, fostering the development of high-performance high-voltage coolant heaters. These heaters are more compact, lightweight, and efficient, leading to an increasing number of large automotive manufacturers choosing EVLINK heaters.
 
Market Trends and Smart Control Systems
Market trends indicate an increasing focus on integrating high-voltage coolant heaters with smart control systems. EVLINK heaters, developed by a dedicated team of engineers, allow vehicle engineers to customize the heaters according to specific needs, offering efficient communication and optimal energy usage.
Technical Advantages of High-Voltage Coolant Heaters
The technical advantages of EVLINK high-voltage coolant heaters include:
 
 

 
PTC Modular Design: EVLINK uses an insulated ceramic heater design with dry burn resistance exceeding 1000 hours, superior to traditional die-cast PTC structures.
 
 
Heat Dissipation: The unique heater structure dissipates the PCB control panel's heat through the water circuit, improving heat dissipation efficiency. High-quality alumina ceramic substrates are used as insulating materials, solving the issues of traditional polyimide films being easily scratched and their insulation performance declining at high temperatures.
 

 
 
Safety Precautions
EVLINK heaters excel in safety measures:
 
Surge Current Management: Utilizing PTC chips with excellent low-temperature start-up performance, the current curve is smooth, reducing surge current, and staggered starts lower the overall current.
 
 
High-Temperature Risk Control: Combining mechanical temperature control switches with glass-encapsulated NTC thermistors ensures safety in high-temperature conditions.
 
 
Waterproof Structure: Silicone components combined with stainless steel plates ensure waterproof performance at the inlet and outlet pipe positions. The optimized installation foot design enhances adaptability to bumps and shocks.
 

 
Future Outlook
With the increasing popularity of large electric vehicles and continuous technological advancements, the market for high-power high-voltage coolant heaters is expected to grow significantly in the coming years. As a premium supplier, EVLINK will continue to lead market trends, providing customers with superior, efficient heating solutions.
