Thermal solution for ECU body electronic control system

Thermally Conductive Interface Materials Designed for Cooling Electronic Components

With the development of the new energy vehicle industry, new forces of new energy vehicle manufacturing continue to emerge, and automotive intelligence also develops rapidly, and technology companies have deployed automotive electronics.

As people have higher and higher requirements for driving comfort, safety, entertainment, economy and other performance, the number of electronic components in the car is also increasing, and the automotive electronic system is also complicated, which is bound to its safety and reliability. put forward higher requirements.

High temperature is an acceleration factor for the aging of electronic components. Poor heat dissipation design will seriously affect the reliability, safety, and durability of electronic components. Cars will also produce bad noise and vibration during driving, causing auto manufacturers to maintain product warranty maintenance. , vehicle quality satisfaction and other issues.

Cohetion series thermal conductivity products have mature thermal management material solutions in new energy vehicle battery pack, motor controller (MCU), body electronic control (ECU), vehicle charger, chassis control, vehicle entertainment and other systems, which can provide heat dissipation /Heat soaking/thermal conduction/thermal insulation and other series of product supporting solutions to help customers achieve the safety and reliability of automotive electronic products.

Thermal solution for ECU body electronic control system

The ECU electronic control unit, also known as the car computer, is a special microcomputer controller for the car. ECU generally has fault self-diagnosis, protection function and adaptive program. With the increase in the degree of automobile intelligence, the functions of ECUs have become more and more complex, and the problem of heat dissipation has gradually become one of the bottlenecks in improving the performance of automobile ECUs. The ECU electronic control unit generally needs to be sealed, and it works in a high temperature environment for a long time, which puts forward higher requirements for the heat dissipation of the ECU circuit board.

ECU

ECU rated voltage: 5V~12V; heat dissipation method: aluminum shell heat dissipation

The heat dissipation solution can use Cohetion thermal conductive silicone gasket LC120 series. LC120 is a thermal conductive gasket developed for low compression force, low thermal resistance and high flexibility. It has double-sided self-adhesion and can be Stable work, meet the flame retardant grade requirements of UL94V0.

thermal pad

How to use:
1: Filling heat conduction between the transformer on the power board and the aluminum die-casting shell;

2: Filling heat conduction between the diode and the copper heat sink on the power board.
