Thermally conductive insulating sheet to solve the heat dissipation of the new energy vehicle inverter
The DC power in the battery is converted into the AC power used in the motor. Hybrid and pure electric vehicles have inverters. They are used as a device for mutual conversion between the high-voltage battery and the motor power, and receive the DC power output by the power battery. , It is inverted into three-phase alternating current and supplied to the motor for operation.
Inverters are generally designed with high-power IGBTs. Long-term operation of IGBTs will generate very high heat accumulation, which will cause the devices to work at high temperatures and affect performance. Therefore, heat dissipation solutions are required. High-power IGBT modules are widely used in power conversion systems, reactive power compensation systems and other fields. With the development of system size and weight toward lighter and smaller, the heat dissipation per unit volume of IGBT modules is getting higher and higher, which seriously harms the system. Stable operation.
The power conversion device in the inverter needs to consider the insulation problem, so Zhaoke Electronics recommends the use of: cost-effective thermal insulation sheet, high insulation, low thermal resistance, high breakdown voltage, with glass fiber, tear resistance and puncture resistance. In addition to the heat dissipation of key components, the inverter usually uses thermally conductive silicone potting glue for sealing and protection. Corrosion occurs.
