Thermally Conductive Grease Save the Heat Dissipation Problem of Electric Vehicle Chips

EV thermal management

New energy electric vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. With the development of science and technology, the intelligence of new energy electric vehicles is also increasing, and the computing power that new energy electric vehicle controllers will bear is also increasing. Heat dissipation have become important considerations to ensure the working efficiency of controller electronic components.

When designing and assembling new energy electric vehicle controllers, the medium is a link that is easily overlooked. However, the quality of the heat conduction medium directly affects the heat dissipation efficiency, so the selection of thermal interface material directly affects the excellent work of the new energy electric vehicle performance.

On May 10, 2022, NHTSA ordered Tesla to recall some Model 3 and Model Y models. The reason is that the central control screen freezes or crashes caused by the overheating of the car. Tesla's official statement shows that when the recalled vehicle is preparing for DC fast charging or during DC fast charging, the CPU of the infotainment system may not be sufficiently cooled, resulting in a slowdown of the CPU and the central touch display, display is sluggish. So, how does the thermal conductive material solve the heat dissipation of new energy?

Thermal conductive silicone grease can closely fit various uneven interfaces, fill large gaps and holes, and improve thermal conductivity and uniformity of thermal conductivity; and can easily penetrate into irregular components The gap between them is cured into high-performance elasticity, which has excellent structural practicability and surface adhesion of structural parts, improves more efficient heat conduction, and also meets electrical insulation, flame retardancy, high temperature resistance, impact resistance, stress reduction and stability. Sex and other comprehensive requirements.

Thermally conductive silicone grease, also called thermal paste, thermal paste, is a high thermal conductivity insulating silicone material. The product also has low oil separation (tends to zero), high and low temperature resistance, water resistance, ozone resistance, and weather aging resistance. It can maintain the state of grease in use for a long time at a temperature of -50 ~ 230°C. Product performance: Thermally conductive silicone grease has high thermal conductivity, excellent thermal conductivity, good electrical insulation (only for insulating thermally conductive silicone grease), wide operating temperature, good stability in use, low consistency and good construction performance.

Thermally conductive silicone grease can be widely applied to various electronic products, the contact surface between heating elements (power tubes, silicon controlled rectifiers, electric heating stacks, etc.) , as a heat transfer medium and moisture-proof, dust-proof, anti-corrosion, shockproof and other properties. It is suitable for surface coating or overall potting of various microwave devices such as microwave communication, microwave transmission equipment, microwave special power supply, and voltage stabilized power supply. This type of silicon material provides excellent thermal conductivity for electronic components that generate heat. Such as: transistors, CPU assembly, thermistors, temperature sensors, automotive electronic components, car refrigerators, power modules, printer heads, etc.
