[0002] In the field of electric vehicles or electromechanical equipment, electric drive systems have become a key technology and are gradually developing towards an integrated structure. Integrated electric drive systems mainly include motors and drive controllers. Since they must operate stably under high power and high load conditions, liquid cooling channels are usually set up in the motors and drive controllers respectively. The heat generated during the operation of the equipment is removed through the heat exchange of the coolant in the liquid cooling channels to ensure that the equipment will not be degraded or damaged due to overheating.

[0003] In order to enable the liquid cooling channels in the two housing metal parts of the motor and the driver to be connected to each other and prevent the coolant from leaking, the prior art uses an external connecting pipe, the two ends of which are respectively sleeved on the connection port openings of the liquid cooling channels of the motor and the driver, and each is sealed with a sealing element. However, although the prior art can realize the assembly connection of the liquid cooling channels, its assembly structure is complicated, which makes the assembly time-consuming, and it is easy to leak at the connection, requiring regular inspection and high maintenance cost. Furthermore, the connecting pipe is exposed and easily damaged, and the pressure resistance of the connecting pipe is low, which affects the reliability of the entire system. In addition, the external connecting pipe is not conducive to the volume reduction of the integrated electric drive system, and will affect the spatial configuration of the integrated electric drive system in the working environment.

[0004] Therefore, it is necessary to develop a liquid-cooled flow channel adapter component and an integrated electric drive system applicable thereto to solve the problems and defects faced by the prior art. Utility Model Content
