Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, and in particular to a snap-fit ​​liquid cooling plate water nozzle sealing structure. Background Technology

[0002] Traditional liquid cooling plate faucets typically require precise positioning before laser welding or riveting. If the faucet has specific directional requirements (such as inlet / outlet angles), specialized tooling fixtures are also needed for positioning. This method has significant drawbacks: repeated adjustments before welding or riveting are necessary, consuming considerable preparation time; once welded, the faucet cannot be disassembled, and damage to one side of the faucet or liquid cooling plate renders the entire system unusable; additional sealing rings or adhesives are required, which are prone to failure due to material aging over long-term use; and the precision error of the tooling fixtures directly affects the faucet installation angle, increasing the risk of mismatch in the liquid cooling system's flow channels. Utility Model Content

[0003] To address the problems mentioned above, this utility model adopts the following technical solution: a snap-fit ​​liquid cooling plate water nozzle sealing structure, comprising a liquid cooling plate body and two water nozzle bases. The surface of the liquid cooling plate body is provided with two water nozzle mounting areas with through holes. A snap-fit ​​connecting key is provided on the inner side wall of the through hole. An annular snap-fit ​​base is provided at the end of the water nozzle base. L-shaped snap-fit ​​through grooves matching the snap-fit ​​connecting key are opened on both sides of the annular snap-fit ​​base. The water nozzle base is axially fixed to the liquid cooling plate body by rotating and snapping, so that the snap-fit ​​connecting key slides along the L-shaped snap-fit ​​through groove and locks. The contact surface between the annular snap-fit ​​base and the liquid cooling plate body is sealed by interference fit.

[0004] Furthermore, the width of the vertical section of the L-shaped snap-fit ​​slot is the same as the width of the snap-fit ​​key, and the height of the horizontal end of the L-shaped snap-fit ​​slot is the same as the height of the snap-fit ​​key.

[0005] Furthermore, the liquid cooling plate body and the water nozzle base are made of aluminum alloy.

[0006] Furthermore, the annular snap-fit ​​base and the water tap base are integrally formed by cold forging process.

[0007] The advantages of this invention are as follows: the water nozzle base and the liquid cooling plate are assembled in two steps, "insertion-rotation," eliminating the need for pre-positioning or tooling assistance, significantly reducing preliminary preparation work. The annular snap-fit ​​base and the liquid cooling plate contact surface directly form a sealing interface through interference fit, completely eliminating consumables such as sealing rings and adhesives, and preventing the risk of aging and leakage. The strict dimensional matching of the L-shaped snap-fit ​​groove and the snap-fit ​​connection key ensures precise locking of the rotation angle, avoiding manual operation deviations and ensuring the consistency of the liquid cooling system flow channel. The water nozzle can be disassembled and reused without damage, supporting single-sided replacement and maintenance, reducing maintenance costs; the universal structure adapts to different specifications of liquid cooling plates, reducing the need for non-standard tooling development. The one-piece molded annular snap-fit ​​base combined with aluminum alloy material has both lightweight and fatigue-resistant characteristics, and there is no risk of loosening or deformation after long-term use.

Therefore, they should not be construed as limitations on this utility model.

[0015] See Figure 1-4 As shown, a snap-fit ​​liquid cooling plate water nozzle sealing structure includes a liquid cooling plate body 1 and two water nozzle bases 2. The surface of the liquid cooling plate body 1 is provided with two water nozzle mounting areas with through holes 11. The inner sidewall of the through holes 11 is provided with snap-fit ​​connecting keys 12. The end of the water nozzle base 2 is provided with an annular snap-fit ​​base 21. The annular snap-fit ​​base 21 has L-shaped snap-fit ​​through grooves 22 on both sides that match the snap-fit ​​connecting keys 12. The water nozzle base 2 is axially fixed to the liquid cooling plate body 1 by rotating and snap-fitting, so that the snap-fit ​​connecting keys 12 slide along the L-shaped snap-fit ​​through grooves 22 and lock. The contact surface between the annular snap-fit ​​base 21 and the liquid cooling plate body 1 is sealed by interference fit.

[0016] The width of the vertical section of the L-shaped snap-fit ​​slot 22 is the same as the width of the snap-fit ​​key 12, and the height of the horizontal end of the L-shaped snap-fit ​​slot 22 is the same as the height of the snap-fit ​​key 12; strict dimensional matching eliminates radial wobble after assembly and ensures the alignment of the liquid cooling channel.

[0017] The liquid cooling plate body 1 and the water nozzle base 2 are made of aluminum alloy; the aluminum alloy's ability to undergo slight plastic deformation enhances the interference fit sealing effect.

[0018] The annular snap-fit ​​base 21 and the water tap base 2 are integrally formed by cold heading process, and the cold heading work hardening increases the tensile strength of the base.

[0019] Working principle: Align the vertical section of the L-shaped snap-fit ​​groove 22 of the water tap base 2 with the snap-fit ​​key 12 of the liquid cooling plate body 1, and insert it vertically into the through hole 11. At this time, an initial gap is maintained between the annular snap-fit ​​base 21 and the liquid cooling plate body 1. Rotate the water tap base 290° clockwise, and the snap-fit ​​key 12 slides along the horizontal section of the L-shaped snap-fit ​​groove 22, forcing the contact surface between the annular snap-fit ​​base 21 and the liquid cooling plate body 1 to generate an axial clamping force. The elastic deformation of the aluminum alloy material forms an interference seal on the contact surface. After the snap-fit ​​key 12 is fully embedded in the horizontal end of the L-shaped snap-fit ​​groove 22, the contact surface between the annular snap-fit ​​base 21 and the liquid cooling plate body 1 undergoes microscopic plastic deformation due to the clamping force, forming a metal-metal sealing interface. The width of the vertical section of the L-shaped snap-fit ​​groove 22 is consistent with the width of the snap-fit ​​key 12, eliminating radial wobble; the height of the horizontal end matches the height of the snap-fit ​​key, limiting axial displacement and ensuring no loosening after locking.
