Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled server cabinet technology, specifically to a bottom leakage detection mechanism for a liquid-cooled server cabinet. Background Technology

[0002] Existing liquid-cooled server racks use liquid cooling to cool servers, offering high cooling efficiency and effectively ensuring server operational quality. However, in actual operation, there is a possibility of leakage in the liquid cooling pipeline. If a coolant leak occurs in an existing liquid-cooled server rack, the sealed bottom of the server can easily lead to coolant accumulation, potentially flooding the server and causing a serious server safety incident. Therefore, there is an urgent need to develop a mechanism for detecting server coolant leaks and ensuring that the server will not be flooded in the event of a leak, thus guaranteeing its safe operation. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a bottom leakage detection mechanism for liquid-cooled server racks, enabling rapid detection of coolant leaks inside the rack and ensuring that the server is not submerged, thus guaranteeing its safe operation.

[0004] A bottom leakage detection mechanism for a liquid-cooled server rack, characterized in that it comprises:

[0005] The inner cabinet contains a liquid cooling system and a server.

[0006] The bottom liquid accumulation area includes the bottom plate and the surrounding plates;

[0007] Outer panel;

[0008] The frame mechanism is used to secure the inner cabinet body and the outer panel.

[0009] And a collection tank;

[0010] The bottom of the inner cabinet body is placed in the center area of ​​the base plate and fixedly connected. A connecting seam is left at the connection between the bottom of the inner cabinet body and the base plate. The area of ​​the base plate is larger than that of the inner cabinet body. The base plate is provided with four convex surrounding plates on all four sides. The surrounding plates and the base plate are joined together to form a bottom liquid accumulation area. The surrounding plates include a back side plate. At least one notch is opened on the upper edge of the back side plate. A liquid accumulation tank is fixedly installed on the back of the back side plate. The liquid accumulation tank is exposed throughout the liquid-cooled server rack. The liquid accumulation tank has a liquid inlet with a connecting notch.

[0011] Its further features are:

[0012] The height of the surrounding panels is 3-5cm, and the upper surface of the liquid accumulation tank is flush with the upper edge of the surrounding panels. This ensures that the liquid inside the inner cabinet will not be higher than the height of the surrounding panels, and that the liquid will not flood the server position.

[0013] The bottom of the base plate is provided with arranged pads to ensure that the entire liquid-cooled server rack does not come into direct contact with the ground during transportation, thus ensuring the safety of transporting the liquid-cooled server rack.

[0014] The outer panel includes a back plate, and an inspection port is provided on the back plate at the position of the liquid inlet of the liquid collection tank. The inspection port is an observation hole, which allows personnel to observe regularly. Even if no liquid is found in the liquid collection tank, it can be reliably determined whether there is a leak of cold liquid through the inspection port.

[0015] Preferably, the liquid accumulation tank is equipped with a liquid level sensor, and the liquid level sensor is connected to an external warning light. When the liquid level sensor comes into contact with liquid, it sends a signal to make the warning light light up, which is used to remind the staff that there is liquid accumulation in the corresponding liquid-cooled server rack.

[0016] With the structure of this utility model, when a leak occurs in the liquid cooling mechanism located in the inner cabinet body, the coolant will drip into the center area of ​​the bottom plate. Since there is a connection seam at the bottom of the inner cabinet body and the bottom plate, the coolant will spread along the connection seam to the bottom liquid accumulation area until the liquid level rises above the bottom of the gap. The coolant will then flow into the liquid accumulation tank along the gap and the liquid inlet. The staff can quickly determine the corresponding liquid cooling mechanism of the liquid-cooled server through the liquid accumulation tank and then carry out maintenance. Even if the staff does not detect it in time, the accumulated liquid will be discharged from the cabinet with the liquid accumulation tank. This ensures that a coolant leak inside the cabinet can be quickly detected and identified, and that the server will not be flooded, thus ensuring the safe operation of the server.

Detailed Implementation

[0021] A bottom leakage detection mechanism for a liquid-cooled server rack, see Figure 1 and Figure 2 It includes an inner cabinet body 10, a bottom liquid accumulation area 20, an outer panel, a frame mechanism 30, and a liquid accumulation tank 40;

[0022] The liquid cooling system and server are housed inside the inner cabinet body 10;

[0023] The bottom liquid accumulation area 20 includes a bottom plate 21 and four surrounding plates 22;

[0024] The outer panel includes a front panel, a back panel 1, and two side panels;

[0025] The frame mechanism 30 is used to fix the inner cabinet body 10 and the outer panel;

[0026] The bottom of the inner cabinet body 10 is placed in the center area of ​​the base plate 21 and fixedly connected. A connection seam is left at the connection between the bottom of the inner cabinet body 10 and the base plate 21. The area of ​​the base plate 21 is larger than the area of ​​the inner cabinet body 10. The base plate 21 is larger than the inner cabinet body 10. There are four convex surrounding plates 22 on all four sides. The surrounding plates 22 and the base plate 21 are spliced ​​to form a bottom liquid accumulation area. There are no gaps at the splicing position of the bottom liquid accumulation area formed by the splicing of the surrounding plates and the base plate to ensure that the liquid will not leak directly downward or sideways. The surrounding plates 22 include a back side plate 221. Notches 222 are opened on both sides of the upper edge of the back side plate 221. A liquid accumulation tank 40 is fixedly installed on the back of the back side plate 221. The liquid accumulation tank 40 is exposed in the entire liquid-cooled server rack. The liquid accumulation tank 40 has an inlet that connects to the notch 222.

[0027] In a specific embodiment, the liquid accumulation tank 40 includes an outer side plate 41, an inner side plate 42, a bottom support plate 43, and two side panels 44. The upper edge of the outer side plate 41 is lower than that of the inner side plate 42, and the lower part of the outer side plate 41 has a guide bevel 411 from top to bottom.

[0028] In practice, the height of the surrounding panels 22 is 3-5cm. The upper edge of the inner side panel 42 on the liquid accumulation tank 40 is flush with the upper edge of the surrounding panels 22. This ensures that the liquid accumulation inside the inner cabinet body 10 will not be higher than the height of the surrounding panels, and that it will not flood the server position.

[0029] The bottom of the base plate 21 is provided with arranged pads 50. The pads 50 ensure that the entire liquid-cooled server rack will not come into direct contact with the ground during transportation, thus ensuring the safety of transporting the liquid-cooled server rack.

[0030] In specific implementation, the outer panel includes a back plate 1. The back plate 1 is provided with an inspection port 101 at the liquid inlet position of the liquid collection tank 40. The inspection port 101 is an observation hole, which allows personnel to observe regularly. Even if no liquid is found in the liquid collection tank 40, it can be reliably determined whether there is a leak of cold liquid through the inspection port 101.

[0031] In practice, a liquid level sensor 60 is installed in the liquid accumulation tank 40. The liquid level sensor 60 is connected to an external warning light (not shown in the figure, but can be set according to actual needs). When the liquid level sensor 60 comes into contact with liquid, it sends a signal to make the warning light light up, which is used to remind the staff that there is liquid accumulation in the corresponding liquid-cooled server rack.

[0032] Its working principle is as follows: When the liquid cooling mechanism located in the inner cabinet leaks, the coolant will drip into the center area of ​​the bottom plate. Since there is a connection seam at the bottom of the inner cabinet and the bottom plate, the coolant will spread along the connection seam to the bottom liquid accumulation area until the liquid level rises above the bottom of the gap. The coolant will then flow into the liquid accumulation tank along the gap and the liquid inlet. The staff can quickly determine the corresponding liquid cooling mechanism of the liquid-cooled server through the liquid accumulation tank and then carry out maintenance. Even if the staff does not detect it in time, the accumulated liquid will be discharged from the cabinet with the liquid accumulation tank. This allows the coolant leak inside the cabinet to be quickly detected and ensures that the server will not be flooded, thus ensuring the safe operation of the server.
