Abstract
Description
Technical Field
[0001] This application relates to the field of liquid-cooled fluid transport technology, and more particularly to quick couplings and liquid cooling systems. Background Technology
[0002] The rapid growth in computing demands has led to increasing cooling requirements and higher demands for cooling efficiency in data centers. Currently, liquid cooling is gradually replacing air cooling as the primary cooling method for heat sources in data centers. In data center liquid cooling systems, a piping system is needed to transfer the coolant to the primary side, enabling heat transfer from the secondary side to the primary side. Within data center server racks, each layer of servers contains multiple heat sources, including but not limited to CPUs and GPUs. Liquid cooling systems require connections between the CPU and GPU cold plates and to the heat exchangers via liquid cooling pipes, ultimately transferring heat to the primary side through the secondary loop and heat exchangers. To improve maintainability and ensure finer-grained maintenance, numerous press-fit quick connectors are installed between the pipes. It is crucial to ensure that these quick connectors do not leak or experience other reliability issues during press-fitting.
[0003] In the process of developing this application, the inventors discovered at least the following problems in the prior art:
[0004] Currently, all pressurized quick couplings on the market exhibit a problem where the valve core does not spring back after insertion or removal under certain pressure. The main reason is the assembly relationship between the valve core, spring, and inner wall of the housing. During insertion and removal, and under the impact of fluid, the spring experiences not only axial rebound force but also lateral force. When the lateral force is relatively large, the valve core will deflect axially and come into contact with the inner wall of the housing, generating friction. Since this frictional force cannot be overcome by the spring's rebound force, the valve core is easily stuck, leading to leakage. Utility Model Content

[0017] In some embodiments, the inner wall of the insertion end of the first housing is provided with a first limiting portion, and the outer wall of the first valve core is provided with a first stop portion disposed opposite to the first limiting portion. The first annular groove is located at one end of the first stop portion near the first limiting portion.

All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0036] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0037] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0038] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0039] This application proposes a quick connector 1000, which is applicable to the connection between various fluid pipelines and can realize pressurized disconnection / coupling between pipelines.
[0040] Please see Figures 1-6 In this embodiment of the application, the quick connector 1000 includes a male connector assembly 100 and a female connector assembly 200 that are plugged into each other. The male connector assembly 100 includes a first housing 110 and a first valve core 120 that are elastically connected. The first housing 110 is sleeved on the first valve core 120. The female connector assembly 200 includes a valve stem 230, a second valve core 220, and a second housing 210 that are sequentially sleeved from the inside to the outside.

Specifically, during the pressurized insertion and removal process of the quick connector 1000, the first protrusion 2331 is located in the first groove 120a, which can restrict the movement of the first valve core 120 in the radial direction, that is, prevent the first valve core 120 from radially deflecting and avoid the first valve core 120 from being stuck; the second protrusion 221 is located in the second groove 110a, which can restrict the movement of the second valve core 220 in the radial direction, that is, prevent the second valve core 220 from radially deflecting and avoid the second valve core 220 from being stuck.
[0042] It should be noted that in this application, the radial direction of each component refers to the direction perpendicular to the axial direction. When the radial direction of a component is mentioned, it does not mean that the component is circular or cylindrical.

[0044] Please see Figure 1 and Figure 2 In this embodiment, the quick connector 1000 has a plugged-in state and a split-out state. In the split-out state, the right end of the male connector assembly 100 is pulled out from the left end of the female connector assembly 200, the first spring 133 is in a naturally extended state, the first valve core 120 is closed, and the first valve core 120 blocks the plugged-in end of the first housing 110; and the second spring 245 is in a naturally extended state, the second valve core 220 is closed, and the second valve core 220 blocks the flow channel between the plugged-in end of the second housing 210 and the valve stem 230. In the plugged-in state, the right end of the male connector assembly 100 is inserted into the left end of the female connector assembly 200, the left end of the second housing 210 is fitted onto the right end of the first housing 110, the first protrusion 2331 is located in the first groove 120a, the left end of the valve stem 230 abuts against the right end of the first valve core 120, under the pushing of the valve stem 230, the first spring 133 is compressed, the first valve core 120 moves to the left (relative to the split state), the first valve core 120 opens, and liquid can flow in or out from the plugged end of the male connector assembly 100; and the second protrusion 221 is located in the second groove 110a, the right end of the first housing 110 abuts against the left end of the second valve core 220, under the pushing of the first housing 110, the second spring 245 is compressed, the second valve core 220 moves to the right (relative to the split state), the second valve core 220 opens, and liquid can flow in or out from the plugged end of the female connector assembly 200.
[0045] Please see Figure 3 and Figure 4 In some embodiments, the first groove 120a is a conical groove, and the first protrusion 2331 is a conical column. This arrangement facilitates the quick insertion of the first protrusion 2331 into the first groove 120a, which is beneficial for achieving rapid positioning between the first valve core 120 and the valve stem 230.
[0046] In the above embodiments, the axial cross section of the first groove 120a can be trapezoidal, semi-circular, triangular / quasi-triangular, etc. Correspondingly, the first protrusion 2331 can be frustum-shaped, hemispherical, pyramidal / quasi-pyramidal, conical / quasi-conical, etc.
[0047] In this embodiment of the application, the second groove 110a and the second protrusion 221 can be annular structures or non-annular structures.
[0048] Preferably, both the second groove 110a and the second protrusion 221 are annular structures, extending in annular shape along the circumference of the first housing 110 and the second valve core 220, respectively. Specifically, the second groove 110a extends in annular shape along the circumference of the right end face of the first housing 110, and the second protrusion 221 extends in annular shape along the circumference of the left end face of the second valve core 220; or, the second groove 110a extends in annular shape along the circumference of the left end face of the second valve core 220, and the second protrusion 221 extends in annular shape along the circumference of the right end face of the first housing 110. This arrangement facilitates the quick insertion of the second protrusion 221 into the second groove 110a, which is beneficial for achieving rapid positioning between the second valve core 220 and the first housing 110.
[0049] Please see Figure 5 In some embodiments, the second groove 110a and the second protrusion 221 are respectively located at the middle of the end face of the insertion end of the first housing 110 and the middle of the end face of the second valve core 220; along the radial direction of the first housing 110 and the second valve core 220, the cross-section of the second groove 110a and the second protrusion 221 is "U". It should be noted that the middle part here refers to the area outside the outermost edge of the end face, not just the innermost center area.
[0050] In the above embodiment, preferably, the second groove 110a is a conical groove and the second protrusion 221 is a conical column. This arrangement facilitates the insertion of the second protrusion 221 into the second groove 110a, which is beneficial for achieving rapid positioning between the second valve core 220 and the first housing 110.
[0051] Please see Figure 6In other embodiments, the second groove 110a is formed by the inner wall of the insertion end of the first housing 110, and the second protrusion 221 is formed on the inner end of the end face of the second valve core 220 corresponding to the insertion end of the first housing 110. In this embodiment, during the insertion and removal process of the quick connector 1000, the side of the second protrusion 221 facing the first housing 110 abuts against the groove wall of the second groove 110a, thereby preventing the second valve core 220 from radially deflecting and thus avoiding the second valve core 220 from getting stuck.
[0052] In the above embodiments, the cross-section of the second groove 110a is trapezoidal, triangular, or rectangular, etc., perpendicular to the axial direction of the first housing 110; the cross-section of the second protrusion 221 is trapezoidal, triangular, or rectangular, etc., perpendicular to the axial direction of the second valve core 220.
[0053] Please see Figure 1 and Figure 2 In some embodiments, the outer wall of the first valve core 120 near the insertion end (right end) of the housing is provided with a first annular groove 120b, and a first sealing ring 131 is provided in the first annular groove 120b. When the first spring 133 is in a naturally extended state, the first sealing ring 131 abuts against the inner wall of the first housing 110. The inner wall of the insertion end of the second housing 210 is provided with a second annular groove 211a. The valve stem 230 includes a stem portion 231 and a head 233. The right side of the head 233... The end is fixed to the inner wall of the right end of the second housing 210 by the rod 231. The diameter of the head 233 is larger than the diameter of the rod 231. The side wall of the head 233 is provided with a third annular groove 233a. The second annular groove 211a and the third annular groove 233a are respectively provided with a second sealing ring 241 and a third sealing ring 243. When the second spring 245 is in a naturally extended state, the inner and outer walls of the second valve core 220 abut against the third sealing ring 243 and the second sealing ring 241, respectively.
[0054] In the above embodiments, when the quick connector 1000 is in the disassembled state, the first sealing ring 131 seals the first housing 110 and the first valve core 120 to prevent liquid in the male connector assembly 100 from flowing out between the first housing 110 and the first valve core 120; the second sealing ring 241 seals the second housing 210 and the second valve core 220 to prevent liquid in the female connector assembly 200 from flowing out between the second housing 210 and the second valve core 220; and the third sealing ring 243 seals the second valve core 220 and the head 233 of the valve stem 230 to prevent liquid in the female connector assembly 200 from flowing out between the second valve core 220 and the head 233 of the valve stem 230. When the quick connector 1000 is in the plugged-in state, the second sealing ring 241 seals the second housing 210 and the first housing 110 to prevent fluid flowing through the quick connector 1000 from flowing out between the first housing 110 and the second housing 210.
[0055] Please continue reading. Figure 1 and Figure 5 In some embodiments, the inner wall of the insertion end (right end) of the first housing 110 is provided with a first limiting portion 111, and the outer wall of the first valve core 120 is provided with a first stop portion 121. The first annular groove 120b is located at one end of the first stop portion 121 near the first limiting portion 111 (the right end of the first stop portion 121). When the quick connector 1000 is in the disassembled state, the first stop portion 121 abuts against the axial end side of the first limiting portion 111. The matching arrangement of the first limiting portion 111 and the first stop portion 121 prevents the first valve core 120 from coming out of the first housing 110, effectively ensuring the sealing stability of the male connector assembly 100 in the disassembled state.
[0056] The inner wall of the insertion end (left end) of the second housing 210 is provided with a second limiting part 211, and the second annular groove 211a is formed at the second limiting part 211. The outer wall of the second valve core 220 away from the second limiting part 211 (the right end of the second valve core 220) is provided with a second stop part 223. When the quick connector 1000 is in the disassembled state, the second stop part 223 abuts against the axial end side of the second limiting part 211. Similarly, this arrangement prevents the second core from coming out of the second housing 210, effectively ensuring the sealing stability of the female connector assembly 200 in the disassembled state.
[0057] Please continue reading. Figure 1 and Figure 5In some embodiments, a first limiting ring 123 protrudes from the end of the first valve core 120 away from the first limiting portion 111 (the left end of the first valve core 120). The left end of the first spring 133 is fixedly connected to the inner wall of the left end of the first housing 110, and the right end of the first spring 133 is sleeved on the first limiting ring 123 and fixedly connected to the left end face of the first limiting portion 111. The first limiting ring 123 can limit the first spring 133, preventing the first spring 133 from radially deflecting, thereby helping to prevent the first valve core 120 from radially deflecting.
[0058] A second limiting ring 225 protrudes from one end of the second valve core 220 away from the second limiting portion 211 (the right end of the second valve core 220). The right end of the second spring 245 is fixedly connected to the inner wall of the right end of the second housing 210, and the left end of the second spring 245 is sleeved on the second limiting ring 225 and fixedly connected to the right end face of the second valve core 220 / the second limiting portion 211. Similarly, this arrangement helps to prevent the second valve core 220 from radially deflecting.
[0059] This application also proposes a liquid cooling system, which includes a pipe assembly and a quick connector 1000. The quick connector 1000 is used for connecting pipes in the pipe assembly. The specific structure of the quick connector 1000 is as described in the above embodiments.
