Description

Technical Field

[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 continuous heat exchange between the server's liquid cooling loop and the external environment. Current server cooling systems often struggle to seal the flow channels of the liquid supply and cooling loops after the male and female connectors are separated, hindering the easy connection and disconnection of the male and female connectors.

[0028] Example 2: A server heat dissipation system includes: a liquid cooling plate 100 with a built-in liquid cooling circuit and a liquid supply circuit 200. The liquid cooling plate 100 is disposed on the surface of the heat-generating element of the server.

When the male sleeve 3 located on the outer side of the upper end of the female sleeve 1 is inserted axially downward into the female sleeve 1, the liquid supply circuit 200 is connected to the liquid cooling circuit of the liquid cooling plate 100.

[0029] A support plate 6 with several through holes 61 is installed between the lower end of the support rod 2 and the inner wall of the female sleeve 1. The upper end of the support rod 2 has a radially outward flange 5. The inner wall of the upper part of the female sleeve 1 has a radially inward first inner flange 7. A floating ring 8 that mates with the lower end face of the male sleeve 3 is sealed between the first inner flange 7 and the flange 5 of the support rod 2. A female spring 9 is provided between the axially movable floating ring 8 and the support plate 6. The male sleeve 3 is provided with a stop ring 12, a male spring 13 and a floating block 14 that mates with the upper end face of the support rod 2 in sequence along the axial direction.

The side wall of the second inner flange 15 is sealed with the axially movable floating block 14.

[0030] The outer wall of the male sleeve 3 is provided with an annular flange 17 extending radially outward. The lower end face of this annular flange 17 is configured as a first inclined surface 181 extending radially outward at the upper end. The female sleeve 1, located above the first inner flange 7, is respectively equipped with a first locking block 191 and a second locking block 192, each capable of radial movement. One end of each of the first locking block 191 and the second locking block 192 is embedded in the female sleeve 1, and a groove 20 is formed on the lower surface of the other end of each. The upper part of one end of the 92 embedded in the female sleeve 1 is provided with a second plane 182 parallel to the first inclined surface 181.

The lower end of each of the two rotating blocks 21 is connected to the female sleeve 1 by a horizontally arranged spring 22, so that the end face of the first locking block 191 and the second locking block 192 embedded in the female sleeve 1 can be flush with the side wall of the first inner flange 7.

[0031] The liquid supply circuit and the liquid cooling circuit of the liquid cooling plate are connected by a liquid cooling connector. When the male and female connectors are separated, the lower ends of the two rotating blocks need to be pressed inward at the same time to make the corresponding locking blocks exit the area above the annular flange. After the floating blocks are reset, they are sealed by the sealing ring under the action of the spring.

[0032] An adhesive layer 23 is provided on the outer side of the aforementioned rotating block 21.

[0033] 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.

[0034] The upper end face of the floating block 14 has a limiting part 141 that extends axially upward and slides in contact with the inner wall of the male sleeve 3.

[0035] Working principle:

[0036] In use, the opposite ends of the male and female sleeves are connected to the liquid supply circuit and the liquid cooling circuit, respectively.

[0037] When the male and female heads are separated:

[0038] The floating block inside the male sleeve moves to the second inner flange under the action of the male spring and seals the male inner flow channel connected to the liquid supply circuit 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 female inner flow channel connected to the liquid cooling circuit through the first sealing ring and the second sealing ring.

[0039] The lower ends of the two rotating blocks rotate away from the male sleeve under the action of the spring, so that their upper ends drive the corresponding first and second locking blocks to move radially inward to the innermost end of their stroke. At this time, the end face of one end of the first and second locking blocks is flush with the side wall of the first inner flange.

[0040] When the male and female connectors are plugged into each other:

[0041] 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.

[0042] As the annular flange on the male sleeve moves down with the male sleeve until its first inclined surface contacts the second inclined surface on the first and second locking blocks; the annular flange continues to move down, simultaneously pushing the first and second locking blocks, which can only move radially, to move outward, causing the upper end of the corresponding rotating block to rotate outward and the lower end to rotate inward, compressing the spring.

[0043] When the annular flange moves below the first and second locking blocks, the first and second locking blocks lose the restraint of the annular flange and reset inward under the action of the spring, thereby allowing the lower surfaces of the first and second locking blocks to overlap with the upper surface of the annular flange to stop the male sleeve.

[0044] When the connected male and female connectors are separated:

[0045] Simultaneously press the lower ends of the two rotating blocks inward so that the upper ends of the two rotating blocks respectively drive the first and second locking blocks to move outward and exit the area above the annular flange. The male sleeve, which has lost its stop position, moves upward under the action of the female spring, so that the male sleeve can be pulled out from the female sleeve. Then, release the lower ends of the two rotating blocks so that the upper ends of the rotating blocks drive the first and second locking blocks to return to the innermost end of their stroke under the action of the spring.

[0046] 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.

[0047] When using the above-mentioned server cooling system, after the male and female connectors are plugged in, the liquid supply circuit and the liquid cooling circuit are connected. After the male and female connectors are separated, the flow channels of the liquid supply circuit and the liquid cooling circuit can be sealed. It also facilitates the mutual plugging and unplugging of the male and female connectors and avoids the loosening of the male and female connectors due to accidental contact, thus improving the safety during use.

[0048] 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.
