AI Technical Summary

⚠Technical Problem

The heat dissipation efficiency of the power module in the existing motor controller is insufficient, making it difficult to meet the heat dissipation requirements of high-power motors, resulting in increased heat loss and affecting the long-term operational stability of the motor controller.

⚗Method used

By employing a heat exchange structure and control components, the fluid flow rate is precisely controlled through flow channel design and sensor feedback system, thereby improving heat exchange efficiency. The integrated design of aluminum substrate and heat dissipation fin plate increases the heat exchange area, and the risk of leakage is reduced through an integrated casting molding process.

🎯Benefits of technology

It improves the heat dissipation efficiency of the power module, ensuring its long-term operation under suitable conditions, reducing costs and minimizing the risk of coolant leakage, and enhancing the overall efficiency of the electric drive system.

Abstract

The application provides an electric control power module and a motor controller, comprising a heat exchange structure, which comprises a heat exchange element and a control assembly. The heat exchange element is provided with a flow channel for heat exchange of fluid. The control assembly is connected to the heat exchange element and is used to collect information of the fluid to control the flow of the fluid into the flow channel. A power module element is in contact with the heat exchange element and is used for heat exchange with the heat exchange element. The cooling effect can be improved to ensure long-term operation.
