Description

[0002] As today's electronic products and data centers continue to pursue higher performance, heat dissipation for related components such as processors and servers has become a key design challenge. As liquid cooling technology becomes increasingly popular due to its efficient heat dissipation, the application of liquid cooling systems and their components in high-performance computing and data centers is becoming increasingly widespread. Proper design of liquid cooling pipe joints has become a crucial factor in ensuring stable, reliable and continuous system operation.

[0003] The server liquid cooling pipe joints in the existing technology are mostly fixed designs. For example, connection and liquid conduction are achieved through a snap-on combination with a thread. During the daily maintenance of servers with this design, the two joints are prone to wear during multiple connections and disconnections, which in turn affects the sealing performance and causes leakage risks. Currently, there are liquid cooling joints with self-locking functions that use movable plug-in snap-on baffles to achieve pipe closure, which requires additional driving parts or operator operations to push the snap-on baffles into the flow channel, which greatly increases the complexity and time cost of maintenance, brings inconvenience to the pipe connection work, and also brings inconvenience to the maintenance of the entire liquid cooling system.

DETAILED DESCRIPTION

[0045] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0047] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0048] Example 1:

[0049] Combine Figures 1 to 7 As shown, an embodiment of the present invention provides a server liquid cooling and heat dissipation joint assembly, including a first joint 100 and a second joint 200 that are plugged into each other, the first joint 100 is provided with a first liquid flow channel 101, and a flow limiting portion 102 is provided at a preset position of the first liquid flow channel 101, and the diameter of the flow limiting portion 102 is smaller than the diameter of the first liquid flow channel 101; a piston ball 110 is slidably connected in the flow limiting portion 102, and the piston ball 110 is connected to a reset spring 120; wherein, the diameter of the piston ball 110 matches the diameter of the flow limiting portion 102.

[0050] It should be noted that the innovation of this solution lies in the unique flow-limiting portion 102 of the first connector 100 and the design of the piston ball 110 and the return spring 120 operating therein. The first liquid flow channel 101 is provided with a flow-limiting portion 102 with a smaller diameter at a predetermined position. This size reduction is conducive to cooperating with the piston ball 110 to control the liquid switch flowing through this part; the diameter of the piston ball 110 matches the flow-limiting portion 102 and can slide within the flow-limiting portion 102. It is connected to the connection portion 103 on the inner wall of the first liquid flow channel 101 by the return spring 120. The advantage of this design is that it provides self-sealing capability when the liquid cooling system needs to be quickly disconnected or connected. The piston ball 110 is automatically blocked by the flow-limiting portion 102, which can effectively prevent liquid leakage when the system is not connected.

[0051] A connecting portion 103 is provided on the inner wall of the first liquid flow channel 101, and one end of the return spring 120 is connected to the connecting portion 103; the second joint 200 is provided with a tongue tube 210, and a second liquid flow channel 211 is provided in the tongue tube 210. A flow hole 212 connected to the second liquid flow channel 211 and an avoidance groove 213 for avoiding the air connection portion 103 are provided on the side wall of one end of the tongue tube 210.

[0052] Among them, the second liquid flow channel 211 inside the tongue tube 210 can correspond to the first liquid flow channel 101 of the first connector 100, and the flow hole 212 on the side wall of one end of the tongue tube 210 plays a key role in fluid transfer, allowing the fluid in the second liquid flow channel 211 to enter the liquid flow channel of the first connector 100; in addition, the avoidance groove 213 of the tongue tube 210 can avoid the connecting portion 103 on the inner wall of the first connector 100 during the connection process. This design allows the tongue tube 210 to be smoothly inserted and connected without worrying about interference with the connection end of the return spring 120, thereby improving the reliability of the connection and the convenience of operation.

[0053] The working principle of the present invention is as follows: when connecting, the second connector 200 is aligned with the first connector 100 and plugged in, so that one end of the tongue tube 210 enters the flow restriction portion 102 and pushes the piston ball 110 to move along the flow restriction portion 102 into the first liquid flow channel 101. The second liquid flow channel 211 and the first liquid flow channel 101 are connected through the flow hole 212 at the front end of the tongue tube 210. During this period, the avoidance groove 213 avoids the connection portion 103 so that the tongue tube 210 can be smoothly inserted to realize the circulation of the pipeline liquid; when the second connector 200 is pulled out, one end of the tongue tube 210 is withdrawn from the first liquid flow channel 101 , the return spring 120 pulls the piston ball 110 back to the flow limiting part 102, thereby blocking the first liquid flow channel 101 and realizing the liquid closure of the joint; this solution realizes rapid connection and disconnection through the design of built-in piston ball 110 and return spring 120. During the plugging process, the piston ball 110 slides in the flow limiting part 102 to cooperate with the flow hole 212 of the tongue tube 210, conveniently completing the conduction of the liquid flow. At the same time, when disconnecting, the piston ball 110 automatically resets to block the liquid flow channel, ensuring that the liquid will not leak out, providing a connection solution that is easy to plug and unplug and has a self-sealing function.

[0054] In this embodiment, the first joint 100 includes a main end cover 130 having an internal cavity, and the two ends of the internal cavity of the main end cover 130 are respectively connected to a connecting tube body 140 and a clamping assembly 150, the connecting tube body 140 is used to connect the liquid cooling pipe, and the clamping assembly 150 is used to clamp the tongue tube 210; wherein, the first liquid flow channel 101 and the flow limiting portion 102 are respectively arranged in the connecting tube body 140; a floating assembly 160 is provided between the connecting tube body 140 and the clamping assembly 150, and a pushing spring (not shown in the figure) is provided on the floating assembly 160, and the pushing spring is used to push the connecting tube body 140 and the clamping assembly 150 to move away from each other.

[0055] It is further explained that, in this embodiment, one end of the connecting tube body 140 is threadedly connected to the main end cover 130; a first limiting slope 131 is provided on the inner wall of one end of the main end cover 130 close to the clamping assembly 150, and along the first direction, the first limiting slope 131 is gradually inclined outward; one end of the clamping tube body 152 is provided with a second limiting slope 1522 that matches the limiting slope.

[0056] During operation, the clamping assembly 150 is first inserted into the interior of the main body end cover 130 along the reverse plug-in direction, and then the floating assembly 160 is installed inside the main body end cover 130, and then the connecting pipe body 140 is assembled on one end of the floating assembly 160. Since the connecting pipe body 140 pipe serves to connect the liquid cooling pipe (not the structure of this assembly, but the pipe of the liquid cooling system), in order to adapt to the length of the liquid cooling pipe in different installation environments, a floating assembly 160 is provided to push the connecting pipe body 140 and the clamping assembly 150 to move away from each other, so that the first limiting inclined surface 131 and the second limiting inclined surface 1522 maintain mutual contact and tight contact, thereby achieving that the clamping assembly 150 is always in contact with the main body end cover 130, maintaining a certain tension, avoiding loosening of the clamping assembly 150, and thus facilitating the sealing of the pipe. In addition, since different liquid cooling pipes are tightened, the connecting pipe body 140 adjusts the pipe installation position through threaded cooperation between the two to achieve corresponding adaptability, and cooperates with the floating component 160 to ensure the stability of the connection position.

[0057] In this embodiment, it is specifically described that the clamping assembly 150 includes an elastic clamping body 151 and a clamping tube body 152 that is sleeved on the outside of the elastic clamping body 151; the elastic clamping body 151 includes an elastic main body 1511 and a plurality of elastic support arms 1512 that are spaced apart in the circumferential direction along one end of the elastic main body 1511, and a through hole 1513 is formed in the middle of the plurality of elastic support arms 1512 for the tongue tube 210 to pass through.

[0058] A first inclined surface 1514 is provided on the outer side wall of each elastic support arm 1512, and the first inclined surface 1514 is gradually inclined toward the middle along the first direction; the plugging direction of the second connector 200 is set to the first direction; an annular inclined surface 1521 is provided on the inner side wall of the clamping tube body 152, and the first inclined surface 1514 matches the annular inclined surface 1521, driving the elastic clamping body 151 to move along the first direction, and the annular inclined surface 1521 cooperates with the first inclined surface 1514 to squeeze the elastic support arm 1512 to gather toward the middle to clamp the tongue tube 210.

[0059] In this embodiment, it is further explained that the clamping assembly 150 also includes an adjusting end cover 153, which is threadedly connected to one end of the clamping tube body 152; a connecting ring 154 is provided on the inner wall of the adjusting end cover 153, and a connecting groove 1515 is provided on the outer wall of the elastic main body 1511, and the connecting ring 154 is rotatably connected in the connecting groove 1515 to rotate the adjusting end cover 153 and the elastic clamping body 151. During adjustment, the adjusting end cover 153 is rotated, and the adjusting end cover 153 pushes the clamping tube body 152 to move relative to the elastic clamping body 151 through the thread, thereby driving the elastic clamping body 151 to clamp or open.

[0060] During operation, the tongue tube 210 is first inserted into the interior of the first joint 100. When the two joints are connected, by rotating the adjusting end cap 153, due to the action of the thread, the adjusting end cap 153 will push the clamping tube body 152 to move relative to the elastic clamping body 151 (approach each other), thereby causing the annular inclined surface 1521 to move toward the elastic clamping body 151. During the movement, the annular inclined surface 1521 will squeeze the elastic support arm 1512 to gather towards the middle, and the diameter of the through hole 1513 in the middle of the elastic clamping body 151 will be reduced, thereby clamping the tongue tube 210; when the second joint 200 needs to be disassembled, the adjusting end cap 153 is rotated in the opposite direction to release the tongue tube 210.

[0061] In this embodiment, the floating assembly 160 includes a floating block 161. A first mounting hole 162 and a second mounting hole are defined on both end surfaces of the floating block 161. A first pin 163 is slidably connected within the first mounting hole 162. A push spring is sleeved around the first pin 163, one end of which is connected to the connecting tube 140. A second pin 164 is slidably connected within the second mounting hole. Another push spring is sleeved around the second pin 163, one end of which is connected to the clamping assembly 150. In this embodiment, the floating assembly 160 functions to maintain stability among the main end cap 130, the connecting tube 140, and the clamping assembly 150. Therefore, the pin and push spring are designed to cooperate. The pin ensures axial positional accuracy during movement and acts as a limiter. For example, when the push spring is compressed to a certain position, the pin abuts against the connecting tube 140 and the clamping assembly 150, preventing further compression and thus preventing excessive adjustment of the pipeline.

[0062] In this embodiment, it is specifically described that the second joint 200 includes a joint body 220 and a connecting cover 230, a tongue tube 210 is provided at one end of the joint body 220, and an annular rotating groove is opened on the outside of the joint body 220; an annular protrusion 240 is provided on the inner wall of the connecting cover 230, and the annular protrusion 240 is rotatably connected to the annular rotating groove; wherein, a first threaded portion for threaded connection with the first joint 100 is provided on the outer wall of the connecting cover 230.

[0063] In order to further ensure the stability of the connection between the first joint 100 and the second joint 200, the second joint 200 of the present solution is also provided with a connection cover 230, which is threadedly connected to the first joint 100 by screwing the connection cover 230, thereby realizing the connection between the two, and the annular protrusion 240 and the annular rotating groove are combined to avoid interference with the tongue tube 210 and the connected liquid cooling pipe.

[0064] In this embodiment, specifically, tongue tube 210 includes a first tube body 214 and a second tube body 215, which are arranged sequentially along the insertion direction of second connector 200. The diameter of first tube body 214 is larger than that of second tube body 215, forming a step 216 therebetween. A limiting protrusion 104 is provided on the inner wall of first connector 100, and is engaged with step 216. The limiting protrusion 104 and step 216 serve to limit and position the tongue tube 210, preventing over-insertion and protecting internal components.

[0065] As an optional solution to this embodiment, a plurality of flow holes 212 are provided on the side wall of the tongue tube 210 along its circumferential direction, wherein the flow holes 212 are one of circular holes, elliptical holes, or square holes. The appropriate hole shape is selected according to different design requirements to provide control over the flow characteristics. For example, flow holes 212 of different shapes can be optimized for specific flow rates, pressure losses, or flow patterns. Such design considerations increase the adaptability and versatility of the tongue tube 210, enabling it to function in different liquid cooling systems.
