Description

Technical Field

[0001] This utility model relates to a liquid cooling connector, belonging to the field of liquid cooling heat dissipation technology. Background Technology

[0002] With the rapid development of computer technology, data center servers are being deployed in high-density and even ultra-high-density configurations to meet the demands of high-performance computing services. During server operation, a significant amount of heat is generated, requiring cooling to ensure normal operation. Compared to traditional distribution cooling methods, most servers currently employ liquid-cooled servers, which offer superior cooling performance. Specifically, liquid-cooled servers contain a liquid cooling loop. This loop connects to the liquid cooler in the server rack via quick-connect couplings or other types of connectors, allowing for uninterrupted heat exchange between the server's liquid cooling loop and the external environment. However, existing liquid cooling connectors often struggle to seal the flow channels after the male and female connectors are separated, and the insertion and separation of these connectors are inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a liquid-cooled connector that, while ensuring the flow channels are open after the male and female connectors are inserted, can also seal the flow channels of their respective connectors after they are separated. It also facilitates the insertion and separation of the male and female connectors and improves the structural stability of the male and female connectors.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a liquid-cooled connector, comprising: a female sleeve, a support rod axially disposed within the female sleeve, and a male sleeve located on the outer side of the upper end of the female sleeve and capable of being axially inserted downward into the female sleeve. The upper and lower ends of the support rod respectively have an upper flange and a lower flange extending radially outward, with the outer diameter of the lower flange being larger than the outer diameter of the upper flange. The inner wall of the upper part of the female sleeve has a first inner flange extending radially inward. A floating ring capable of axial movement is fitted on the outer side of the support rod. A female spring is disposed between the floating ring, which cooperates with the lower end face of the male sleeve, and the lower flange of the support rod. When the floating ring moves to the space between the upper flange and the first inner flange of the support rod under the action of the female spring, its inner and outer surfaces are respectively sealed and engaged with the upper flange of the support rod and the first inner flange of the female sleeve through a second sealing ring installed on the upper flange and a first sealing ring installed on the first inner flange.

[0005] The male sleeve is provided with a stop ring, a male spring and a floating block that mates with the upper end face of the support rod in sequence along the axial direction. The inner wall of the lower end of the male sleeve, on which the stop ring is fixedly installed, has a second inner flange that runs radially inward. When the axially movable floating block moves to the lower end of the male sleeve under the action of the male spring, the side wall of the second inner flange is sealed with the floating block through a third sealing ring installed on the floating block.

[0006] The outer wall of the male sleeve is provided with an upper stop flange and a lower stop flange that extend radially outward, thereby forming a stop groove between the upper stop flange and the lower stop flange that are spaced apart along the axial direction. The lower end face of the lower stop flange is set as a first inclined surface that extends radially outward at the upper end. A retaining ring that can move left and right is installed on the female sleeve and above the first inner flange. A second inclined surface parallel to the first inclined surface is formed on the left side of the retaining ring. The pressing part of the retaining ring is located on the right side of the female sleeve and is connected to the female sleeve by a horizontally extending spring.

[0007] The following are further improvements to the above technical solution:

[0008] 1. In the above scheme, two annular mounting grooves are provided on the side wall of the first inner flange, which are spaced apart in the vertical direction. A first sealing ring is installed in the lower annular mounting groove, and a fourth sealing ring is installed in the upper annular mounting groove. Both the fourth sealing ring and the first sealing ring can be sealed and fitted with the outer wall of the male sleeve embedded in the female sleeve.

[0009] 2. In the above scheme, the lower end face of the floating ring and located outside the female head spring has a guide portion extending downward in the axial direction, and this guide portion slides in contact with the inner wall of the female head sleeve.

[0010] 3. In the above scheme, the upper end surface of the floating block has a limiting part that extends axially upward and slides in contact with the inner wall of the male sleeve.

[0011] 4. In the above scheme, the outer circumferential surface of the lower flange and the inner wall of the female sleeve are connected by at least one set of protrusions and grooves.

[0012] 5. In the above scheme, the lower flange portion is provided with a plurality of through holes.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] This utility model relates to a liquid-cooled connector. The outer wall of the male connector sleeve has an upper stop flange and a lower stop flange extending radially outwards, forming a stop groove between the axially spaced upper and lower stop flanges. The lower end face of the lower stop flange is configured as a first inclined surface extending radially outwards from its upper end. A movable retaining ring is installed on the female connector sleeve above the first inner flange. A second inclined surface parallel to the first inclined surface is formed on the left side of the retaining ring's engaging portion. The pressing portion of the retaining ring is located on the right side of the female connector sleeve and is connected to the female connector sleeve via a horizontally extending spring, thus enabling the male and female connectors to be inserted. Based on the open flow channel, the male and female heads can be sealed after separation, which also facilitates the insertion and separation of the male and female heads and improves the structural stability of the male and female heads. In addition, two annular mounting grooves are provided on the side wall of the first inner flange, which are spaced apart in the vertical direction. The lower annular mounting groove is equipped with a first sealing ring, and the upper annular mounting groove is equipped with a fourth sealing ring. Both the fourth sealing ring and the first sealing ring can seal with the outer wall of the male head sleeve embedded in the female head sleeve, which can effectively prevent the fluid from overflowing during the transmission process and improve the safety and stability of use.

[0024] The outer wall of the male sleeve 3 is provided with an upper stop flange 171 and a lower stop flange 172 extending radially outward, thereby forming a stop groove 173 between the upper stop flange 171 and the lower stop flange 172 which are spaced apart along the axial direction.

[0029] The outer wall of the male sleeve 3 is provided with an upper stop flange 171 and a lower stop flange 172 extending radially outward, thereby forming a stop groove 173 between the upper stop flange 171 and the lower stop flange 172 which are spaced apart along the axial direction. The lower end face of the lower stop flange 172 is set as a first inclined surface 181 extending radially outward at the upper end. A retaining ring 19 that can move left and right is installed on the female sleeve 1 and above the first inner flange 7. A second inclined surface 182 parallel to the first inclined surface 181 is formed on the left side of the retaining ring 19. The pressing part 192 of the retaining ring 19 is located on the right side of the female sleeve 1 and is connected to the female sleeve 1 by a horizontally extending spring 20.

[0030] Two annular mounting grooves 71 are provided on the side wall of the first inner flange 7, which are spaced apart in the vertical direction. A first sealing ring 10 is installed in the lower annular mounting groove 71, and a fourth sealing ring 21 is installed in the upper annular mounting groove 71. Both the fourth sealing ring 21 and the first sealing ring 10 can seal with the outer wall of the male sleeve 3 embedded in the female sleeve 1, which can effectively prevent leakage during fluid transmission and improve the safety and stability of use.

[0031] The floating ring 8 has a guide portion 81 extending axially downward on its lower end surface and outside the female head spring 9. This guide portion 81 slides in contact with the inner wall of the female head sleeve 1.

[0032] The outer circumferential surface of the lower flange 6 and the inner wall of the female sleeve 1 are connected by at least one set of protrusions and grooves.

[0033] The working principle is as follows:

[0034] When in use, the opposite ends of the male and female sleeves are connected to the fluid pipeline.

[0035] When the male and female heads are separated:

[0036] The floating block inside the male sleeve moves to the second inner flange under the action of the male spring and seals the inner flow channel of the male head through the third sealing ring. The floating ring inside the female sleeve moves to the space between the upper flange and the first inner flange under the action of the female spring and seals the inner flow channel of the female head through the first sealing ring and the second sealing ring.

[0037] The retaining ring moves to the rightmost end of its travel under the action of the spring. At this time, the end face of the right end of the retaining ring's locking part is flush with the side wall of the first inner flange.

[0038] When the male and female connectors are plugged into each other:

[0039] The male sleeve moves downward and enters the female sleeve, causing the outer surface of the male sleeve to slide into contact with the side wall of the first inner flange inside the female sleeve. The downward-moving male sleeve pushes the floating ring inside the female sleeve to move downward and compress the female spring. The floating block inside the male sleeve moves upward relative to the male sleeve and compresses the male spring under the push of the upper end face of the fixed support rod. At this time, the flow channels inside the male and female sleeves are connected and interconnected.

[0040] As the lower stop flange on the male sleeve moves down with the male sleeve until its first inclined surface contacts the second inclined surface on the snap ring's engagement portion; the lower stop flange continues to move down, pushing the snap ring, which can only move left and right, to the left, causing the pressing portion to compress the spring; when the lower stop flange moves to a position lower than the snap ring's engagement portion, the engagement portion loses the restriction of the lower stop flange and resets to the right under the action of the spring, thereby allowing it to be embedded in the stop groove.

[0041] When the connected male and female connectors are separated:

[0042] Pressing the pressing part of the retaining ring to the left causes the retaining part on the retaining ring to move to the left and exit the stop groove. The male sleeve, which has lost its stop, moves upward under the action of the female sleeve spring, so that the male sleeve can be pulled out from the female sleeve. Then, release the pressing part of the retaining ring so that the retaining ring returns to the rightmost end of its stroke under the action of the spring.

[0043] After the male and female springs lose their compressive force, they reset. Under the action of the reset male spring, the floating block inside the male sleeve moves back to the second inner flange and re-seals the inner flow channel of the male head through the third sealing ring. Under the action of the reset female spring, the floating ring inside the female sleeve moves back between the upper flange and the first inner flange and re-seals the inner flow channel of the female head through the first and second sealing rings.

[0044] When using the above-mentioned liquid-cooled connector, in addition to ensuring the flow channel is open after the male and female connectors are inserted, it can also seal the flow channels of each connector after they are separated. It also facilitates the insertion and separation of the male and female connectors and improves the structural stability of the male and female connectors. Furthermore, it can effectively prevent the overflow of fluid during the transmission process and improve the safety and stability of use.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
