Description

Technical Field

[0001] This utility model belongs to the technical field of automatic exhaust valve drainage, and particularly relates to a drainage device for a manifold piping system in a liquid-cooled cabinet. Background Technology

[0002] In high-density liquid-cooled cabinets, several vent valves are typically installed at the top of the Manifold piping to promptly release any gas within the Manifold system, ensuring the entire liquid cooling system reaches its most efficient cooling state. Due to the vent valves (such as...) Figure 1 As shown, it needs to be deployed at the highest point of the Manifold piping system. This means that if the vent valve leaks, coolant may leak into the blade server below it, posing a significant risk to the stable operation of the entire computing system. Summary of the Invention

[0003] To overcome the technical problems described in the background, this utility model provides a drainage device for the manifold piping system of a liquid-cooled cabinet. A drainage pipe assembly is installed on the vent of the automatic vent valve of the manifold piping system to drain the coolant that is accidentally leaked from the automatic vent valve to the bottom of the cabinet, preventing it from entering the cabinet and improving the operational stability of the entire computing system.

[0004] The technical solution of this utility model is: a drainage device for a manifold piping system for a liquid-cooled cabinet, including an automatic vent valve, wherein the vent nozzle on the automatic vent valve is connected to a drainage pipe assembly for draining the coolant that accidentally flows out of the vent nozzle to a location away from the automatic vent valve.

[0005] Furthermore, the drainage tube assembly includes a drainage connection tube, one end of which is connected to the exhaust port of the automatic exhaust valve and the other end extends to the bottom of the cabinet.

[0006] Furthermore, the drainage pipe assembly includes a drainage connecting pipe, a vertical opening pipe, and a lower drainage pipe. The end of the drainage connecting pipe near the automatic exhaust valve is nested and connected to the exhaust port of the automatic exhaust valve. The end of the drainage connecting pipe away from the automatic exhaust valve is provided with a vertically extending vertical opening pipe. The upper end of the vertical opening pipe is open and higher than the upper side of the drainage connecting pipe. The lower end of the vertical opening pipe is provided with a lower drainage pipe extending downward to the bottom of the cabinet. The drainage connecting pipe, the vertical opening pipe, and the lower drainage pipe are interconnected.

[0007] Furthermore, a filter plug for filtering gas is embedded in the upper opening of the vertical open tube.

[0008] Furthermore, the drainage tube assembly includes a lower guide housing and a drainage interface. The lower guide housing is nested on the valve body of the automatic exhaust valve and covers the exhaust nozzle of the automatic exhaust valve upwards. Below the exhaust nozzle of the automatic exhaust valve, a guide slope bottom surface is formed that extends downwards from the exhaust nozzle of the automatic exhaust valve to the portion of the automatic exhaust valve away from the exhaust nozzle. The bottom of the portion of the lower guide housing away from the exhaust nozzle of the automatic exhaust valve is provided with a drainage interface for guiding the liquid in the lower guide housing to the bottom of the cabinet.

[0009] Furthermore, the lower guide housing is provided with an upper cover, the lower end of which is provided with an embedding buckle for embedding and snapping onto the lower guide housing, and the middle part is provided with a positioning sleeve for nesting on the valve top of the automatic exhaust valve.

[0010] Furthermore, the upper cover is a rigid transparent plastic cover.

[0011] Furthermore, the bottom surface of the lower guide housing protrudes upward to form a nested cylinder that is nested in the valve body of the automatic exhaust valve, and the inner wall of the nested cylinder is provided with a sealing groove for embedding a sealing ring.

[0012] Furthermore, multiple reinforcing ribs are provided between the nested cylinder and the side wall of the adjacent lower guide shell to improve the connection strength.

[0013] Furthermore, an insert cap is embedded in the upper opening of the vertically open tube, and a filter plug is disposed through the center of the insert cap.

[0014] The beneficial effects of this utility model due to the adoption of the above-mentioned technology are as follows.

[0015] 1. This utility model provides a drain pipe assembly on the vent of the automatic vent valve in the Manifold piping system to drain the coolant that may leak from the automatic vent valve to the bottom of the cabinet, preventing it from entering the cabinet and improving the operational stability of the entire computing system.

[0016] 2. This utility model adopts a single-pipe drainage structure, which is simple in structure. Furthermore, there is a gap between the lower end of the drainage connection pipe and the bottom of the cabinet to prevent the coolant from forming a liquid seal at the lower end of the drainage connection pipe after it is discharged, which would make it difficult for the gas from the subsequent exhaust nozzle to be discharged.

[0017] 3. This utility model adopts a side T-shaped drainage structure. The drainage connecting pipe, the vertical opening pipe and the lower drainage pipe are interconnected to form a side T-shaped structure. The vertical opening pipe can avoid the problem of affecting the exhaust of the exhaust nozzle by adding the drainage pipe assembly. In particular, if the vertical opening pipe does not exist, the gas from the exhaust nozzle will be difficult to discharge after the bottom of the lower drainage pipe is sealed by liquid.

[0018] 4. This utility model adopts a side T-shaped drainage structure with exhaust filtration function, which can prevent coolant from splashing out of the vertical opening pipe with the airflow if coolant leakage occurs.

[0019] 5. This utility model adopts a wrap-around flow-guiding structure, which can prevent coolant from splashing out of the vertical opening pipe with the airflow if coolant leakage occurs. There is an unobstructed opening between the end of the upper cover away from the exhaust nozzle and the upper edge of the lower guide shell, which facilitates venting. At the same time, the transparent upper cover and the inclined bottom surface of the guide shell cooperate with each other to facilitate observation of the exhaust nozzle from above during maintenance and repair. In particular, the part of the upper cover above the exhaust nozzle is set as a convex mirror structure, which can magnify the observation and help to observe whether there are traces of coolant leakage in the automatic exhaust valve during maintenance and repair.

[0033] Example 1: As Figure 2 As shown, this utility model provides a single-pipe drainage device for a manifold piping system in a liquid-cooled cabinet. It includes an automatic vent valve, and the vent nozzle 3 on the automatic vent valve is connected to a drainage pipe assembly for draining the coolant that accidentally leaks out of the vent nozzle 3 to a location away from the automatic vent valve. The drainage pipe assembly includes a drainage connecting pipe 4, one end of which is nested or embedded in the vent nozzle 3 and is connected to the vent nozzle 3. The other end of the drainage connecting pipe 4 extends to the bottom of the cabinet to drain the accidentally leaked coolant to the bottom of the cabinet. A gap is provided between the lower end of the drainage connecting pipe 4 and the bottom of the cabinet to prevent the formation of a liquid seal at the lower end of the drainage connecting pipe 4 after the coolant is drained, which would make it difficult for the gas from the vent nozzle 3 to be discharged.

[0034] Example 2: Figure 3 As shown, this utility model provides a side T-shaped drainage device for a manifold piping system in a liquid-cooled cabinet, including an automatic vent valve. The vent nozzle 3 on the automatic vent valve is connected to a drainage pipe assembly for diverting any coolant accidentally flowing out of the vent nozzle 3 to a location away from the automatic vent valve. The drainage pipe assembly includes a drainage connecting pipe 4, a vertical open pipe 5, and a lower drainage pipe 6. The end of the drainage connecting pipe 4 near the automatic vent valve is nested and connected to the vent nozzle 3 of the automatic vent valve, while the end of the drainage connecting pipe 4 away from the automatic vent valve is positioned... There is a vertically extending vertical opening pipe 5. The upper end of the vertical opening pipe 5 is open and is higher than the upper side of the drainage connection pipe 4. The lower end of the vertical opening pipe 5 is provided with a lower drainage pipe 6 extending downward to the bottom of the cabinet. The drainage connection pipe 4, the vertical opening pipe 5 and the lower drainage pipe 6 are interconnected to form a side T-shaped structure. The vertical opening pipe 5 can avoid the problem of the exhaust nozzle 3 being affected by the addition of the drainage pipe assembly. In particular, if the vertical opening pipe 5 is not present, the bottom of the lower drainage pipe 6 will be sealed by liquid, making it difficult for the gas from the exhaust nozzle 3 to be discharged.

[0035] Example 3: Figure 4As shown, this utility model provides a side T-shaped drainage device with exhaust filtration function for a manifold piping system of a liquid-cooled cabinet. It includes an automatic exhaust valve, with an exhaust nozzle 3 on the automatic exhaust valve connected to a drainage pipe assembly for diverting any coolant accidentally flowing out of the exhaust nozzle 3 to a location away from the automatic exhaust valve. The drainage pipe assembly includes a drainage connecting pipe 4, a vertical open pipe 5, and a lower drainage pipe 6. The end of the drainage connecting pipe 4 near the automatic exhaust valve is nested and connected to the exhaust nozzle 3 of the automatic exhaust valve. The drainage connecting pipe 4 is located away from the automatic exhaust valve. The valve end is provided with a vertically extending vertical opening pipe 5. The upper end of the vertical opening pipe 5 is open and higher than the upper side of the drain connection pipe 4. The lower end of the vertical opening pipe 5 is provided with a lower drain pipe 6 extending downward to the bottom of the cabinet. The drain connection pipe 4, the vertical opening pipe 5 and the lower drain pipe 6 are interconnected. An embedded cap 7 is embedded in the upper opening of the vertical opening pipe 5. A filter plug 8 for filtering gas is provided through the center of the embedded cap 7. In this way, if coolant leakage occurs, coolant can be prevented from splashing out of the vertical opening pipe 5 with the airflow.

[0036] Example 4: Figures 5-12 As shown, this utility model provides a wrap-around drainage device for a manifold piping system of a liquid-cooled cabinet, including an automatic vent valve. The vent nozzle 3 on the automatic vent valve is connected to a drainage pipe assembly for guiding the coolant that accidentally flows out of the vent nozzle 3 to a location away from the automatic vent valve. The drainage pipe assembly includes a lower guide housing 10 and a drainage interface 11. The lower guide housing 10 is nested on the valve body 2 of the automatic vent valve and covers the vent nozzle 3 of the automatic vent valve upwards. A guide slope bottom surface 13 is formed below the vent nozzle 3 of the automatic vent valve, extending downwards from a portion of the vent nozzle 3 to a portion of the automatic vent valve away from the vent nozzle 3. The bottom of the portion of the lower guide housing 10 away from the vent nozzle 3 of the automatic vent valve is provided with a drainage interface 11 for guiding the liquid in the lower guide housing 10 to the bottom of the cabinet.

[0037] The lower guide housing 10 is provided with an upper cover 9 made of rigid transparent plastic, which makes it convenient to observe the exhaust nozzle 3 from above. In particular, the part of the upper cover 9 above the exhaust nozzle 3 is set as a convex mirror structure, which can magnify the observation and help with observation during maintenance and repair.

[0038] There is an open opening between the end of the upper cover 9 away from the exhaust nozzle 3 and the upper edge of the lower guide housing 10, which facilitates exhaust.

[0039] The lower end of the upper cover 9 is provided with an embedding buckle 17 for embedding and snapping onto the lower guide housing 10, and the middle is provided with a positioning sleeve 16 for nesting on the valve top 1 of the automatic exhaust valve. This can fix the position between the upper cover 9 and the valve top 1, so that the exhaust nozzle 3 is located on the center vertical section of the lower guide housing 10, and prevent the exhaust nozzle 3 from being too close to the lower guide housing 10 and affecting the discharge of coolant.

[0040] The lower guide housing 10 has an upwardly protruding inclined bottom surface 13 that forms a nested cylinder 12 nested in the valve body 2 of the automatic exhaust valve. The inner side wall of the nested cylinder 12 is provided with a sealing groove 15 for embedding a sealing ring. Multiple reinforcing ribs 14 are provided between the nested cylinder 12 and the adjacent side wall of the lower guide housing 10 to improve the connection strength.

[0041] Before assembling the automatic air vent valve onto the Manifold piping system, the lower guide housing 10 is nested on the valve body 2 from bottom to top, that is, the nesting cylinder 12 is nested on the valve body 2, and a sealing ring is embedded between the nesting cylinder 12 and the valve body 2. At this time, the upper cover 9 is nested on the valve top 1 from top to bottom, and the positioning sleeve 16 on the upper cover 9 is just snapped on the valve top 1. The part of the positioning sleeve 16 facing the air vent 3 has a notch. The coolant that is accidentally leaked from the air vent 3 enters the guide slope bottom surface 13 and flows through both sides of the nesting cylinder 12 to the lower guide housing 10 at the bottommost drain port 11. The drain port 11 is nested and connected to a drain pipe that extends to the bottom of the cabinet, which drains the coolant to the bottom of the cabinet. Due to the structure of the lower guide housing 10, a certain amount of coolant is allowed to be discharged to the bottom of the cabinet relatively slowly, which makes it easier to find out whether there is a coolant leakage fault in the automatic air vent valve during maintenance and repair.
