AI Technical Summary
In existing liquid cooling heat exchange systems, the connection strength of pipe joints is low, which can easily lead to the liquid cooling pipes and liquid cooling plates detaching, causing coolant leakage and affecting the normal heat dissipation of battery cells.
The connector assembly design includes a first connector and a second connector. The inner wall of the second connector has a stepped portion and a bevel. The end of the first connector abuts against the bevel and is engaged by a limiting portion to increase the connection strength. At the same time, a sealing ring is used to enhance the sealing performance and ensure the reliability of the connector connection.
It improves the sealing and strength of the joint connection, reduces the risk of coolant leakage, ensures a stable connection between the liquid cooling pipeline and the liquid cooling plate, and avoids damage to individual battery cells due to poor heat dissipation.
