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.
