Problems solved by technology

[0003] The installation space of the BSG system is limited, the working environment is harsh, and the high temperature generated during the operation of the system has a great impact on it, especially for the electronic components in the control inverter. If effective heat dissipation cannot be achieved, the electronic components may be damaged. fail
Traditional air cooling has poor heat dissipation effect and is difficult to meet heat dissipation requirements
Liquid cooling requires the design of a special heat sink. At present, the relevant heat sinks are designed for the BSG system of passenger cars, and the design of heat sinks for commercial vehicles is still blank.
Moreover, due to the inner flow channel and the need to meet the miniaturization development requirements of the BSG system, the processing technology of the cooling plate is relatively complicated. Therefore, it is urgent to propose a processing method for the cooling plate of the BSG motor inverter to reduce the difficulty of processing the cooling plate and improve the reliability. Productivity, meeting the needs of commercial vehicle BSG systems
