Description

Technical Field

[0001] This utility model mainly relates to the field of battery water tap installation and connection technology, specifically to a leak-proof new energy battery water tap installation base. Background Technology

[0002] With the rapid development of new energy vehicles, energy storage power stations, and other fields, the stability and reliability of the thermal management system of lithium-ion batteries, as the core power source and energy storage unit, are of paramount importance. Liquid cooling technology, due to its efficient heat exchange capabilities, has become the mainstream cooling solution for large-capacity, high-power-density battery packs.

[0003] In a liquid cooling system, coolant circulates through channels or cooling plates inside the battery pack, carrying away the heat generated by the battery. The injection and drainage of coolant, as well as the balancing of system pressure, are achieved through dedicated injection / venting ports (commonly called "water nozzles"). The water nozzle mounting base typically refers to the two pipe fittings used for installing and connecting the water nozzle: one is fixed to the liquid cooling plate, and the other connects to the coolant pipe.

[0004] Currently, traditional battery water tap mounting bases generally suffer from the following technical pain points:

[0005] Insufficient sealing reliability: Most bases use a single O-ring for radial or end-face sealing. Under the long-term vibration of the battery pack, thermal shock (causing the plastic parts to shrink and expand), and chemical corrosion of the coolant, the single sealing ring is prone to aging, wear, or permanent compression deformation, leading to seal failure and coolant leakage.

[0006] Poor connection strength and vibration resistance: The water nozzle and base are mostly connected by simple plug-in or snap-fit ​​connections. Under continuous mechanical vibration and impact during vehicle movement or equipment operation, this connection method is prone to loosening or even detachment, causing serious leakage accidents. Therefore, it is necessary to propose an improvement measure to solve the above-mentioned technical problems.

[0007] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0008] 1. The technical problem to be solved by the utility model:

[0009] This utility model provides a leak-proof water tap mounting base for new energy batteries to solve the technical problems existing in the background art.

[0010] 2. Technical Solution:

[0011] To achieve the above objectives, the technical solution provided by this utility model is as follows: a leak-proof water tap mounting base for new energy batteries, comprising a first water tap mounting connector and a second water tap mounting connector. The first water tap mounting connector is mounted on a liquid cooling plate, and the second water tap mounting connector is connected to an external cooling water pipe. Multiple annular grooves are spaced apart on the inner wall of the second connecting pipe of the second water tap mounting connector, and a second annular sealing ring is installed in each of the annular grooves. A first threaded connecting pipe section extends outward from the rear of the first connecting pipe of the first water tap mounting connector, and the front of the first water tap mounting connector is inserted into the second connecting pipe of the second water tap mounting connector, compressing the second annular sealing ring to achieve a seal. A threaded connecting sleeve is also installed on the outer side of the second connecting pipe of the second water tap mounting connector, and the interface between the second water tap mounting connector and the first water tap mounting connector is connected via the threaded connecting sleeve.

[0012] Furthermore, the outer side of the second connecting pipe opening is machined with external threads, and the outer side of the first threaded connecting pipe section is also correspondingly machined with external threads. The inner side of the threaded connecting sleeve is correspondingly machined with internal threads. The threaded connecting sleeve is threadedly installed on the second connecting pipe opening. When the second water tap installation connector is inserted into the first water tap installation connector, rotating the threaded connecting sleeve allows part of the threaded connecting sleeve to be threadedly installed on the second connecting pipe opening, and the remaining part to be threadedly installed on the first threaded connecting pipe section.

[0013] Furthermore, a first annular sealing ring is installed at the connection point between the outer end face of the first threaded connecting pipe section and the second connecting pipe port.

[0014] Furthermore, the outer diameter of the first connecting pipe port is adapted to the inner diameter of the second connecting pipe port; the length of the first connecting pipe port is adapted to the length of the second connecting pipe port.

[0015] Furthermore, the outer diameter of the second connecting pipe opening is adapted to the outer diameter of the first threaded connecting pipe section.

[0016] Furthermore, the second annular sealing ring is installed and fixed in the annular groove by adhesive bonding.

[0017] 3. Beneficial effects:

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] I. Extremely high sealing reliability: The multi-seal ring design forms multiple independent sealing barriers, which greatly reduces the risk of overall leakage due to the failure of a single seal ring, significantly improves the safety level of the battery pack, ensures the long-term stable operation of the battery thermal management system, avoids serious safety accidents such as battery short circuits and thermal runaway caused by leakage, and extends the service life of the battery pack.

[0020] II. Excellent connection stability and vibration resistance: The second water nozzle mounting joint is connected to the first water nozzle mounting joint using a threaded connecting sleeve. The threaded engagement provides a strong mechanical locking force. This connection method can effectively resist long-term vibration, impact and shaking during vehicle operation, prevent the water nozzle from loosening or falling out, and ensure the absolute reliability of the connection. Its overall design is ingenious and highly practical. It effectively solves the leakage and connection reliability problems of key interfaces in the liquid cooling system of new energy batteries, and has high market promotion value and application prospects.

[0032] See attached document Figure 1-4This embodiment of a leak-proof water tap mounting base for a new energy battery includes a first water tap mounting connector 1 and a second water tap mounting connector 2. The first water tap mounting connector 1 is mounted on a liquid cooling plate, and the second water tap mounting connector 2 is connected to an external cooling water pipe. Multiple annular grooves 22 are spaced apart on the inner wall of the second connecting pipe port 21 of the second water tap mounting connector 2, and a second annular sealing ring 23 is installed in each annular groove 22. A first threaded connecting pipe section 12 extends outward from the rear of the first connecting pipe port 11 of the first water tap mounting connector 1, and the front of the first water tap mounting connector 1 is inserted into the second connecting pipe port 21 of the second water tap mounting connector 2, compressing the second annular sealing ring 23 to achieve a seal. A threaded connecting sleeve 3 is also installed on the outer side of the second connecting pipe port 21 of the second water tap mounting connector 2, and the interface between the second water tap mounting connector 2 and the first water tap mounting connector 1 is connected via the threaded connecting sleeve 3.
