Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a quick-insert water pipe connector device for a liquid-cooled battery box and the liquid-cooled battery box. Background Art

[0002] Energy storage battery boxes often integrate a lower case with a liquid cooling plate, manufactured using processes such as aluminum extrusion welding and stamping. As a core component, the battery box directly impacts the safety of energy storage equipment. With the development of liquid-cooled battery boxes, the requirements for the box's protection level are becoming increasingly stringent. Therefore, the sealing of the battery box is crucial. This sealing also significantly affects the heat exchange efficiency of the battery cells within the battery pack box.

[0003] In existing technology, most connectors use a single-channel quick-connect structure or a dual-channel non-quick-connect method to connect to the battery box housing. These methods are relatively costly in terms of installation and material costs, are time-consuming and labor-intensive, and often provide poor sealing. Poor sealing not only affects the normal operation of the liquid cooling system but can also cause coolant leakage, posing a potential safety hazard to the battery pack and the surrounding environment. Utility Model Content

[0007] Through the internal interface and the external interface on both sides of the connecting pipe in the utility model, it is ensured that the internal interface and the external interface are correctly connected to the liquid cooling pipeline inside the battery box and the external connector respectively.

[0008] In the utility model, a sealing ring and a circular groove for embedding the sealing ring are provided on one side of the joint base close to the internal joint, and the circular groove is located on the outer side of the interface.

[0009] The sealing ring of the utility model provides an additional sealing layer for the battery box to prevent liquid leakage. The circular groove provides a positioning for the sealing ring to ensure its stability on the connector base.

[0010] In the utility model, the sealing ring part extends out of the circular groove.

[0011] In the present invention, the sealing ring partially extends out of the circular groove, so that the extended portion can well abut against the outer wall of the battery box, reducing the risk of liquid leakage.

[0013] The mounting holes in the present invention provide mounting locations for the combination bolts, so that the connector base can be firmly fixed on the battery box, and the risk of leakage caused by loosening of the connector base is reduced.

[0014] In the utility model, reinforcing ribs are provided at the periphery of the mounting hole.

[0015] By providing the reinforcing ribs in the utility model, the strength of the joint base is improved, so that the combined bolts can be more stable during fixing and are not easily damaged.

[0016] In the present invention, the number of the base sockets is 2.

[0017] The dual-socket design of the present invention allows two connecting pipes to be connected simultaneously, so that the liquid cooling system can distribute coolant more efficiently, continuously and effectively provide cooling for the battery, thereby keeping the battery within a suitable operating temperature range, extending battery life and improving system performance.

The coolant flows within the liquid cooling plate, effectively removing the heat generated by the battery cells and improving the heat exchange efficiency.

[0020] In the utility model, the battery box body is further provided with an external water inlet connector and an external water outlet connector for connecting to an external interface.

[0021] By setting the external water inlet joint in the utility model, an external water source is connected to provide coolant for the battery box, and the used coolant is discharged through the external water outlet joint to realize the circulation of the coolant and improve the heat exchange efficiency of the battery box.
