Innovations

PTC Modular Design

  • Unique modular design to address the demand for higher power, which traditional heaters cannot meet.
  • Custom-made PTC elements with Curie temperature points to ensure good voltage resistance and low-temperature starting performance.

Matrix Arrangement Structure

  • 3-row matrix arrangement to improve heat dissipation efficiency.
  • High-quality alumina ceramic substrates used as insulation materials, solving the issues of traditional polyimide films being prone to scratches and reduced insulation performance at high temperatures

Copper Busbar Connection

  • Using copper busbars to connect modules, avoiding the messiness and potential short circuits or leakage associated with traditional wiring.

 

Safety Precautions

Surge Current Management

  • Using PTC chips with good low-temperature starting performance to smooth the current curve and reduce surge current.
  • Staggered starting to lower the overall current.

Transient Overvoltage Protection

  • High-voltage power supply filter capacitors and overvoltage protection devices.
  • Choosing 1600V IGBTs to increase breakdown voltage.

High-Temperature Risk Control

  • Combining mechanical temperature control switches with glass-sealed NTC thermistors to ensure safety under high temperatures.

Waterproof Structure

  • Using silicone parts combined with stainless steel plates to ensure waterproof performance at inlet and outlet pipes.
  • Optimized mounting feet design to enhance resistance to bumps and impacts.

 

 

 

Control Logic

Soft Starting

  • Grouped starting, each group controlled by independent IGBTs, to achieve smooth startup.

PID Regulation

  • Collaborating with customers to debug PID adjustments and optimize energy-saving strategies.

Switching Without Load

Combining contactors with IGBTs to reduce the impact on contactors during switching, preventing adhesion.

Conclusion

Through innovative PTC modular design, reliable safety precautions, and precise control logic, EVLINK's automotive water heaters offer efficient and reliable heating solutions. These innovations not only enhance product performance but also further solidify EVLINK's leading position in the automotive thermal management field.
