Thick Film Heater Size:

 

Thick film heaters are superior to PTC heaters in terms of efficiency, reliability, cost, and heating effect.

(1) High thermal efficiency: COP increased by 14%
(2) High integration: The number of parts is reduced by 20%, and the weight is reduced by 28%
(3) High compactness: The volume is reduced by 22%
(4) Fast response speed: Full power output is increased by 100 times
(5) More precise control: High precision and no surge
(6) Strong pressure resistance: Can withstand 1500V high voltage

 

 

 

 

Our products have passed professional CE certification. You can see the CE certification certificate in the picture below, and the certificate includes multiple models of PTC electric heaters.

 

 

 

 

1. Q: What are the advantages of thick film electric heaters compared with traditional PTC heaters?

A: Thick film heaters have higher energy efficiency (up to 95% or more), faster heating speed (second response), smaller size, and high power density, which are suitable for the strict requirements of new energy vehicles on space and energy consumption.

 

2. Q: What new energy vehicle scenarios are suitable for the 7-15kW power range?

A: 7-10kW is mostly used for passenger car battery/cabin heating, 10-15kW is suitable for commercial vehicles or extremely cold regions. It can meet the needs of large-capacity battery packs for rapid preheating and in-car heating.

 

3. Q: How is the safety of thick film heaters guaranteed?

A: It uses insulating ceramic substrates and high-temperature resistant thick film materials, has overcurrent, overtemperature, and short-circuit protection functions, and has no open flames, meeting the automotive grade IP67 protection and flame retardant standards.

 

4. Q: Why are thick film heaters more suitable for high voltage platforms (such as 800V)?

A: Thick film technology can adapt to high voltage by adjusting the resistor paste formula, has strong pressure resistance, and its efficiency is not affected by voltage increase, while traditional PTC is prone to efficiency reduction under high voltage.

 

5. Q: How to solve the problem of start-up delay in a low temperature environment?

A: Thick film heater directly heats the coolant/air, and can output heat in 3-5 seconds. It cooperates with the preheating strategy of the battery management system (BMS) to eliminate the bottleneck of low-temperature cold start.
