Thermal conductive silicone sheet: Empowering the automotive chassis control system and solving the heat dissipation dilemma

Driven by the waves of automotive electrification and intelligence, the chassis control system, as the core hub of the vehicle, is facing performance challenges. The integration degree of core components such as high-precision sensors, domain controllers, and electric actuators is constantly increasing, while complex working conditions such as high temperature, vibration, and humidity have become invisible shackles restricting the stability of the system. Thermal conductive silicone sheets, with their outstanding thermal management capabilities and reliability, have become a key solution to break through the heat dissipation bottleneck, safeguarding the safety and efficiency of the chassis control system.

Thermal conductive silicone sheet: Reshaping the boundaries of thermal management with technology

1.Effective heat conduction, breaking through the heat flow bottleneck: By using high thermal conductivity silicone base material and combining with nano-scale filler technology, a low thermal resistance connection between the heating element and the heat sink is achieved. Experimental data show that under the same working conditions, the use of thermal conductive silicone sheets can reduce the junction temperature of the chip by 15-20℃, significantly delaying the risk of thermal failure.

2. Flexible adaptation to cope with complex working conditions:

Anti-vibration design: The hardness of 30-80 Shore A is adjustable. It absorbs mechanical vibration energy and avoids contact surface cracking caused by thermal stress.

Weather resistance breakthrough: Wide temperature range operation from -40℃ to 200℃, resistant to salt spray and oil erosion, ensuring long-term reliability.

Insulation protection: Volume resistivity ≥1.0 × 10¹² Ω·cm, effectively isolating high-voltage components and enhancing the electromagnetic compatibility of the system.
