Thermal solution for EMS motor management system

Thermal 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 EMS Motor Management System

Compared with traditional industrial motors, new energy vehicle motors have higher requirements on power density, and the increase in power density will inevitably pose higher challenges to the heat dissipation design of the motor management system.

thermal pad

EMS (pure electric bus) rated voltage: 500V;
Rated power: 80kw~200kw;
Cooling method: water cooling

This cooling solution can use Cohetion thermal pad LC200R series between the motor controller and the radiator and combine with water cooling, which can effectively reduce the thermal resistance of the system, improve the power density of the system, and enhance the module’s ability to resist mechanical vibration and mechanical shock. Application requirements for long-term vibration of electric buses.

thermal sheet

LC200R series thermal pads are materials with high thermal conductivity, with breakdown voltage greater than 10Kv/mm, high tear strength, low thermal resistance under low pressure, self-adhesive and easy to operate.

How to use: Fill between the transformer on the power board and the aluminum die-casting shell to improve thermal conductivity.
