A blind-fit quick connector for data center liquid cooling systems

Abstract

This utility model discloses a blind-plug quick connector for a data center liquid cooling system, including a first connector and a second connector. A calibration sleeve is movably fitted onto the upper surface of the second connector. A pressing block is located near the upper surface of the second connector. An opening is formed on the front surface of the calibration sleeve, and a flared tube is mounted on its upper surface. Pull-up grooves are longitudinally formed on both sides of the calibration sleeve, and guide rods are fixedly installed inside the pull-up grooves. This blind-plug quick connector for a data center liquid cooling system allows for easier insertion of the first connector into the second connector when the first connector is inserted into the second connector without a visible view. Because the calibration sleeve extends a certain height above the second connector, this makes it easier to insert the first connector into the second connector when there is no visible view.

Description

Technical Field

[0001] This utility model relates to the field of quick connector technology, and in particular to a blind-plug quick connector for data center liquid cooling systems. Background Technology

[0002] With the rapid development of the digital economy, data centers, as computing infrastructure, are experiencing continuous increases in computing density and equipment power. The heat generated by core hardware such as servers and storage devices during operation is growing exponentially. Traditional air-cooling solutions, limited by heat dissipation efficiency and energy consumption bottlenecks, are no longer sufficient to meet the cooling needs of high-density data centers. Liquid cooling systems, with their advantages of high heat dissipation efficiency, low energy consumption, and low noise, are gradually becoming the mainstream technology for data center cooling.

[0003] In the operation and maintenance of liquid cooling systems, quick connectors are key components for achieving "connection and disconnection" of coolant circuits. They are widely used in scenarios such as server module replacement, equipment maintenance, and pipeline repair, and their performance directly affects the operation and maintenance efficiency and reliability of the liquid cooling system. Among them, blind-fit quick connectors are suitable for environments with dense data center equipment and narrow operating spaces (such as multi-layer equipment stacking inside server racks and concealed pipeline layouts). They can complete the connection without direct visibility or in limited operating space, making them an indispensable core component of liquid cooling systems.

[0004] Currently, data centers are increasingly demanding higher operational efficiency from their liquid cooling systems. This necessitates efficient connection and disconnection of quick-connect couplings to minimize equipment downtime. Simultaneously, the sealing and connection accuracy of the coolant circuit directly impact system safety, requiring the avoidance of risks such as coolant leakage and equipment short circuits due to connection deviations. However, existing blind-fit quick-connect couplings for data center liquid cooling systems have several shortcomings. They lack effective guiding and calibration structures, necessitating repeated adjustments to the coupling position for alignment in situations with limited visibility or confined spaces. This not only prolongs equipment maintenance time but also increases the risk of wear on the coupling ports due to alignment deviations, reducing coupling lifespan. Some couplings even require auxiliary tools for positioning, further increasing operational complexity. Utility Model Content

[0005] The main purpose of this invention is to provide a blind-plug quick connector for data center liquid cooling systems, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A blind-fit quick connector for a data center liquid cooling system includes a first connector and a second connector. A calibration sleeve is movably fitted on the surface of the second connector at its upper end, and a pressing block is provided on the surface of the second connector near its upper end.

[0007] More preferably, the front surface of the calibration sleeve has an opening, the upper surface of the calibration sleeve is fitted with a horn tube, the two sides of the calibration sleeve have longitudinally formed lifting grooves, a guide rod is fixedly installed inside the lifting groove, and a spring is fitted on the surface of the guide rod.

[0008] More preferably, sleeve blocks are fixedly installed on both sides of the second connector and near the upper end, and the sleeve blocks are fitted onto the guide rod.

[0009] More preferably, the upper end of the spring is fixed to the sleeve block, and the lower end of the spring is fixed to the lower inner surface of the lifting groove.

[0010] A further preferred embodiment has a pressing ring fixedly fitted onto the surface of the first connector.

[0011] Compared with the prior art, this utility model proposes a blind-plug quick connector for data center liquid cooling systems, which has the following advantages: In this invention, by setting up a first connector, a second connector, a pressing block, and a calibration sleeve to cooperate with each other, when the first connector is inserted into the second connector without a field of vision, the calibration sleeve extends to a certain height above the second connector, so when the first connector is inserted into the second connector without a field of vision, the first connector can be inserted into the second connector more easily.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] like Figure 1-4 As shown, a blind-plug quick connector for a data center liquid cooling system includes a first connector 1 and a second connector 2. A calibration sleeve 4 is movably fitted on the surface of the second connector 2 at its upper end, and a pressing block 3 is provided on the surface of the second connector 2 near its upper end.

[0018] In a preferred embodiment: the front surface of the calibration sleeve 4 has an opening 401, the upper surface of the calibration sleeve 4 is fitted with a horn tube 402, the two sides of the calibration sleeve 4 have longitudinally formed lifting grooves 403, the inside of the lifting grooves 403 is fixedly installed with guide rods 404, and the surface of the guide rods 404 is fitted with springs 405.

[0019] In the above structure, the spring 405 is in a compressed state in its natural state. When the calibration sleeve 4 is not pressed down, the calibration sleeve 4 extends to a certain height above the second connector 2. Therefore, when the first connector 1 is inserted into the second connector 2 without a field of vision, the first connector 1 can be inserted into the second connector 2 more easily.

[0020] In a preferred embodiment, a sleeve 201 is fixedly installed on both sides of the second connector 2 near the upper end, and the sleeve 201 is sleeved on the guide rod 404.

[0021] In the above structure, when the calibration sleeve 4 is pressed down, since the upper end of the spring 405 is fixed to the sleeve block 201 and the lower end of the spring 405 is fixed to the inner lower surface of the lifting groove 403, the spring 405 will be stretched and unfolded as the calibration sleeve 4 descends. Thus, when the first connector 1 and the second connector 2 are disconnected, the calibration sleeve 4 will rise under the action of the spring 405.

[0022] In a preferred embodiment: the upper end of the spring 405 is fixed to the sleeve block 201, and the lower end of the spring 405 is fixed to the lower inner surface of the lifting groove 403.

[0023] In a preferred embodiment, a pressing ring 101 is fixedly sleeved on the surface of connector 1.

[0024] When this utility model is in use, if connector 1 is inserted into connector 2 without a field of vision, the calibration sleeve 4 extends to a certain height above connector 2. Therefore, when connector 1 is inserted into connector 2 without a field of vision, it is easier to insert connector 1 into connector 2. When connector 1 and connector 2 are separated, pressing the pressing block 3 into connector 2 releases the locking state between connector 1 and connector 2, allowing connector 1 to be pulled out of connector 2. After connector 1 is pulled out, the calibration sleeve 4 will rise again under the action of spring 405, preparing for the next docking use.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
