The valve has the advantages that flow resistance is small, and adverse factors that in the prior art, due to the fact that a fluid flow channel is located between the inner wall of the shell and the valve element, fluid flow resistance is large, and turbulent flow and vortex are likely to be generated can be avoided; cleaning is facilitated, and the leakage probability is reduced.

Description

Technical Field

[0001] The invention belongs to the technical field of fluid pipeline connectors, and in particular relates to a quick connector for a server host liquid cooling system. Background Art

[0002] The aforementioned servers include but are not limited to WEB servers, application servers, file servers, database servers, cloud servers, backup servers, proxy servers, FTD servers, load balancers, cache servers, etc., and play a vital role in the network. Because they store and process a wide range of data and information on the network, they are regarded as the soul of the network. Since the server runs uninterruptedly around the clock, it needs to be cooled in order to improve heat dissipation efficiency, reduce energy consumption, and reduce noise to adapt to different working environments. The ways to cool the server include air cooling such as air cooling (computer room air conditioning), natural cooling and liquid cooling, i.e. liquid cooling. Liquid cooling is generally valued by people because of its high heat dissipation efficiency and significant energy-saving effect compared to air cooling, as well as the ability to save space, etc.

[0003] Technical information related to quick connectors for liquid cooling systems can be found in the published Chinese patent documents, such as CN202011236U (a quick connector for a water cooling system of a data processing center), CN222334783U (a self-locking quick-change fluid connector), and CN213158952U (quick plug connector). A typical example is the "male connector, female connector and quick connector assembly" recommended by CN103953009A. Although this patent can deliver on the technical effects recorded in the technical effect column of its specification, it has the following shortcomings: According to the description in paragraph 0040 of the patent specification and in combination with the figures of the patent, it can be seen that due to the unreasonable structural design of the male and female connectors and related components, when in use, the channel in which the fluid flows (the patent calls it "liquid flow channel") is manifested as flowing in the male connector fluid channel between the valve core and the inner wall of the male connector housing, so the fluid flow resistance is relatively large and the pressure drop is high, there are more turbulence and eddy currents, resulting in large pressure loss, because the gap in the circulation channel between the outer wall of the valve core and the housing of the fluid is objectively not uniform, and the roughness or structural mutation (such as steps, threads) and springs (such as the first, second and third compression springs referred to in the patent) will significantly increase the fluid flow resistance; it is not convenient to clean on demand; and the risk of leakage is high.

[0031] See also Figure 5 And combined with Figure 1 and Figure 3 The aforementioned female plug valve core 23 is composed of a left valve head 231, a right valve head 232 and a valve head connected to a valve stem 233. The left valve head 231 is formed at the left end of the valve head connected to the valve stem 233, and the right valve head 232 is formed at the right end of the valve head connected to the valve stem 233.

The edge of the right side surface of the aforementioned right valve head 232 abuts against the left side surface of the retaining ring 21141. A left valve head sealing ring 2311 is embedded in the aforementioned left valve head 231. When the aforementioned male When the male and female plug housings 11 and 21 are in a non-plugged and separated state, the left valve head sealing ring 2311 forms a sealing fit with the cavity wall of the sliding sleeve cavity 221 of the aforementioned sliding sleeve 22, and when the male and female plug housings 11 and 21 are in a plugged and fitted state, the left valve head sealing ring 2311 is located together with the left valve head 231 at the right end of the aforementioned active hollow plug column cavity 121 and a gap is maintained between the cavity wall of the active hollow plug column cavity 121 for fluid to pass through.

[0034] See also Figure 6 The right cavity opening of the sleeve cavity 221 of the aforementioned sleeve 22 is configured in the shape of a bell mouth 222 for increasing the flow surface and reducing the flow resistance at the same time.

[0035] See also Figure 7 And combined with Figures 2 to 3 Since the male and female plug mechanisms 1 and 2 are respectively arranged on the cooling cabinet drawer and the cooling cabinet body of the cooling cabinet of the structural system of the cooling device such as the server, the cooling device drawer mating joint 113 of the male plug housing 11 is mated with the interface on the cooling drawer, and the female plug housing external thread 215 on the right end outer wall of the female plug housing 21 is mated with the interface on the cooling cabinet body. When the cooling cabinet is to be used, that is, when the cooling liquid in the cooling cabinet is to be circulated and refluxed for cooling, the cooling cabinet drawer is pushed to insert the positive hollow plug post 12 of the structural system of the male plug housing 11 into the female plug housing cavity 211. During the insertion process, due to the mutual guiding effect of the male plug hollow plug post guide slope 114 and the female plug housing cavity guide slope 212, the mating can be conveniently, quickly and accurately performed.

Assuming that the cooling fluid is introduced from the cooling device drawer fitting cavity 1131, it will sequentially pass through the left end of the active hollow plug cavity 121, the male connector valve core 14, and the space between the left valve head 231 and the middle of the active hollow plug cavity 121, the space between the valve head connecting the valve stem 233 and the right end of the active hollow plug cavity 121, and the space between the valve head connecting the valve stem 233 and the sliding sleeve cavity 221, until it is led out from the right end port 2113 of the female plug shell cavity 211 and enters the cooling cabinet body to form a circulating reflux (through the corresponding pipeline), which is formed by Figure 7 Conversely, the fluid can also flow in from the right end port 2113 of the female plug housing cavity 211 and sequentially pass through the female plug valve core 23, the sleeve cavity 221 of the sleeve 22 and the positive hollow plug column cavity 121 and flow out from the cooling device drawer fitting cavity 1131 to form a circulation reflux.

[0036] When the male and female plug housings 11 and 21 are to be disconnected, they can be separated by pulling out the cooling cabinet drawer. Due to the restoring force of the male plug valve core return spring 15 and the valve sleeve return spring 24 that were previously in compression and energy storage, the male and female plug mechanisms 1 and 2 are respectively in the state of being compressed and stored.
