Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a liquid cooling pipe structure for a water connector. Background Technology

[0002] With the rapid development of new energy vehicles, they are being chosen by more and more consumers due to their advantages of low pollution and low travel costs. At the same time, thermal management issues arising during the fast charging process of new energy vehicles affect their charging efficiency. Batteries generate a lot of heat when charging at high power, which, if not controlled, may lead to overheating, affecting battery life, performance, and even safety.

[0003] Therefore, the introduction of liquid cooling pipes as a key component in the cooling system is precisely for efficient heat dissipation, ensuring that the battery and charging system operate within the optimal temperature range. The higher the flow rate of the cooling medium, the higher the cooling efficiency, but this also places higher demands on the mechanical properties of the cooling system. As the transmission channel for the cooling medium, the burst resistance, sealing performance, and tensile strength of the liquid cooling pipes all affect the reliability of the entire cooling system, thus imposing higher requirements on the structure of the liquid cooling pipes.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Combined with appendix Figure 1-2As shown, a liquid cooling pipe structure for a water connector includes: a connector 1, a crimping sleeve 3, a flexible hose 2, and an outer sheath layer 4. At least two flexible hoses 2 are disposed within the outer sheath layer 4, and each end of the flexible hose is connected to a connector 1. The flexible hose 2 is sleeved on the pagoda structure of each connector 1, and a crimping sleeve 3 is disposed outside the flexible hose. The flexible hose is compressed by the deformation of the crimping sleeve to tightly connect the flexible hose 2 to the connector 1.

[0023] The hose 2 has a three-layer structure: the inner and outer layers are rubber layers, namely the inner rubber layer 21 and the outer rubber layer 23; the middle layer is an aramid fiber reinforcement layer 22. The entire hose is formed by vulcanization and is connected and fixed to the connector 1 through the crimping sleeve 3.

[0024] In this embodiment, the above-described hose structure consists of two sets, arranged vertically. Both sets of hoses are fitted within the outer sheath layer 4 to improve their abrasion resistance. Connecting nuts are retained at the joints on both sides of the hoses to connect with the mating ends and form a cooling medium flow loop.

[0025] Each of the connectors 1 has a connecting nut at the end furthest from the hose so as to connect with the mating end to form a cooling medium flow loop.

[0026] The outer sheath layer 4 includes a braided mesh covering layer 41 and a wear-resistant sheath layer 42, wherein the braided mesh covering layer wraps and fixes multiple sets of hoses, and the braided mesh covering layer wraps and fixes no less than two hoses.

[0027] As a preferred option, the wear-resistant sheath layer is made of rubber.

[0028] The key points of this utility model are as follows:

[0029] 1. The hose has a three-layer reinforced structure: the inner and outer layers are rubber layers, and the middle layer is an aramid fiber reinforcement layer. The hose is formed by vulcanization and has good compressive strength, tensile strength and burst resistance.

[0030] 2. Large-size multi-tube integration: Two hose assemblies are arranged one above the other and fixed by an outer braided layer to form a liquid inlet and outlet circuit. One hose is used for liquid inlet and the other hose is used for liquid outlet.

[0031] 3. The outermost wear-resistant sheath layer uses a rubber sheath, which is both aesthetically pleasing and provides a soft feel, enhancing the wear resistance of the cooling pipes and extending their service life.

[0032] 4. Connector 1 is connected to hose 2 via crimp sleeve 3: Hose 2 is first fitted onto the pagoda structure of connector 1, and then the outer layer is fitted into crimp sleeve 3. Mechanical force causes the crimp sleeve to deform to a certain extent, thereby compressing the hose and achieving stability and sealing of the connection between the metal connector and the hose.

[0033] This invention can significantly improve the tensile strength, sealing performance and burst resistance of liquid cooling pipe structural connections, and can ensure that the cooling medium in the cooling system operates at a higher flow rate and pressure, thereby greatly improving the heat exchange efficiency and reliability of the cooling system.

[0034] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
