Description

Technical Field

[0001] The utility model relates to fields such as 5G BBU cooling technology, and specifically, a 5G BBU single-phase immersion liquid cooling cabinet. Background Art

[0002] The "Information and Communications Industry Green and Low-Carbon Development Action Plan (2022-2025)" jointly issued by the Ministry of Industry and Information Technology and seven other departments in August 2022 states: "By 2025, the power usage effectiveness (PUE) of newly built large and ultra-large data centers nationwide will be reduced to below 1.3." It also states: "Improve the energy efficiency of IT facilities. Actively apply liquid-cooled and high-temperature IT equipment to improve the energy efficiency of IT equipment in data centers." The 5G BBU immersion liquid cooling cabinet is a type of data center liquid cooling. Currently, existing technologies or patents include cold plate liquid cooling, single-phase immersion liquid cooling, two-phase immersion liquid cooling, and air cooling.

[0003] Immersion liquid cooling has a lower PUE than cold plate liquid cooling and air cooling, a higher power saving rate, and occupies less space. Compared with single-phase immersion liquid cooling, two-phase immersion liquid cooling requires a specially sealed pressure vessel and is not conducive to online maintenance.

[0004] Current single-phase immersion liquid cooling systems are generally composed of independently installed immersion cabinets and heat exchange systems. The immersion cabinets mainly include the cabinets and immersion tanks, while the heat exchange systems are loaded with independent CDUs. Since the two are set up separately, they occupy a lot of space.

[0005] In addition, in the existing single-phase immersion liquid cooling technology, the immersion pools are different, the immersion objects and the immersion quantity are different, the wiring methods for weak current and optical fiber are also different, and the convenience of maintenance is also different; and for the operation of 5GBBU, it is best to perform online maintenance without affecting the operation of other 5G BBUs. The size of the immersion pool will determine the size of the immersion liquid cooling cabinet. The smaller the size of the immersion liquid cooling cabinet, the easier it is to install and maintain later.

[0006] The immersion tank of the current single-phase immersion liquid cooling system is large in size, and is not well compatible with weak current and optical fiber wiring space, and is not very convenient for online maintenance. It is not ideal for the integration of the liquid separation device.

[0007] In addition, the liquid separation device in the immersion tank of the current single-phase immersion liquid cooling system is usually an integrated closed liquid separation cavity. The cooled single-phase coolant is injected into the liquid separation cavity through a circulating pump. A single hole is opened on the inside of the liquid separation cavity corresponding to each 5G BBU, and the coolant is sprayed to each 5G BBU through the small hole.

[0008] The use of the above liquid separation device results in different and uneven flow rates of single-phase coolant in each 5G BBU. The heat emitted by each 5G BBU cannot be removed evenly and promptly, resulting in large temperature differences between the single-phase coolant and the working environment of the 5G BBU.

[0054] Embodiment 1:

[0055] A 5G BBU single-phase immersion liquid cooling cabinet integrates the heat exchange system, the immersion pool, the liquid cooling water inlet system and the liquid cooling water return system into one, so that it can be fully loaded with one cabinet, and the whole 5G BBU single-phase immersion liquid cooling technology system is more miniaturized, such as Figures 1 to 13As shown, the 5G BBU single-phase immersion liquid cooling cabinet includes a cabinet 38 and a 5G BBU single-phase immersion liquid cooling system integrated in the cabinet 38. The cabinet 38 includes a frame 39 for installing the 5G BBU single-phase immersion liquid cooling system and a panel 37 surrounding the frame 39. The 5G BBU single-phase immersion liquid cooling system includes an immersion pool 4 and a heat exchange system, a liquid cooling water inlet system, and a liquid cooling water outlet system surrounding the sides and bottom of the immersion pool 4. The liquid cooling water inlet system includes a cooling liquid supply pipe 13 provided with a plurality of cooling liquid supply branches with quick-connection ball valves 19, and the plurality of cooling liquid supply branches are connected to the water inlet side of the immersion pool 4. The cooling liquid supply pipe 13 is connected to the heat exchange system. The liquid cooling water outlet system includes a water outlet pipe 11 provided with a water outlet pipe quick-connection ball valve 20. One end of the water outlet pipe 11 is connected to the water outlet side of the immersion pool 4, and the other end of the water outlet pipe 11 is connected to the heat exchange system.

[0056] As a preferred design, the 5G BBU single-phase immersion liquid cooling cabinet includes a cabinet 38 and a 5G BBU single-phase immersion liquid cooling system integrated in the cabinet 38. The cabinet 38 includes a frame 39 for installing the 5G BBU single-phase immersion liquid cooling system and a panel 37 surrounding the frame 39. The frame 39 includes a bottom plate provided at the bottom, a plurality of columns provided around the bottom plate, and a border with the same area as the bottom plate provided at the top of the columns. The inside of the frame is provided with a platform for placing the immersion pool 4 using rods (columns) and plates.

[0057] The 5G BBU single-phase immersion liquid cooling system includes a heat exchange system for cooling the cooling liquid, a liquid cooling water inlet system for delivering the cooled cooling liquid to the immersion pool 4 to remove the heat of the 5G BBU, and a liquid cooling water outlet system for outputting the high-temperature cooling liquid after removing the heat of the 5G BBU to the heat exchange system for further cooling. The heat exchange system, the liquid cooling water inlet system, and the liquid cooling water outlet system surround the sides and bottom of the immersion pool 4.

[0058] The liquid cooling water inlet system includes a cooling liquid supply pipe 13 provided with a plurality of cooling liquid supply branches with quick-connection ball valves 19 through a tee fitting or the like.

[0059] In use, the cooling liquid for cooling is cooled by the heat exchange system to obtain low-temperature cooling liquid, which is transported from the cooling liquid outlet end side of the heat exchange system into the cooling liquid supply water pipe 13, and then transported into the immersion tank 4 through the water inlet side of the immersion tank 4 via the multiple cooling liquid supply water branches with quick-connection ball valves 19 to exchange heat and take away the heat generated by the internal components of the immersion tank 4. After heat exchange, the cooling liquid becomes high-temperature cooling liquid, which, under the action of the self-circulation function of the heat exchange system, is transported from the water outlet side of the immersion tank 4 through the backwater pipe 11 provided with a backwater pipe quick-connection ball valve 20 into the heat exchange system from the cooling liquid recovery end side of the heat exchange system to become low-temperature cooling liquid again, and then repeatedly circulate and operate.

[0060] Embodiment 2:

[0061] This embodiment is further optimized on the basis of the above-mentioned embodiments, and the same as the foregoing technical solutions will not be repeated here. As shown in Figures 1 to 13 As shown in the figure, in order to better achieve the 5G BBU single-phase immersion liquid cooling cabinet, the following setting structure is particularly adopted: the heat exchange system comprises a heat exchange circulating pump 15 and a heat exchange device 14, and the heat exchange circulating pump 15 and the heat exchange device 14 are both arranged in the space region between the outer bottom of the immersion tank 4 and the inner bottom of the frame 39 in the cabinet 38, and the heat exchange circulating pump 15 and the heat exchange device 14 are located at two adjacent sides; the water outlet end of the heat exchange circulating pump 15 is connected to the cooling liquid inlet of the heat exchange device 14 through a pipeline system, and an electromagnetic valve 27, a water flow switch 23, a stop valve 25 and a pressure sensor 24 are sequentially arranged on the pipeline system between the water outlet end of the heat exchange circulating pump 15 and the cooling liquid inlet of the heat exchange device 14, and the electromagnetic valve 27 is arranged close to the water outlet end side of the heat exchange circulating pump 15; the cooling liquid outlet of the heat exchange device is connected to the cooling liquid supply water pipe 13 through a cooling liquid supply water pipe 32; and the water inlet end of the heat exchange circulating pump 15 (the cooling liquid recovery end side of the heat exchange system) is connected to the backwater pipe 11 through a pipeline system.

[0062] As a preferred design scheme, the heat exchange system is provided with a heat exchange circulation pump 15 and a heat exchange device 14. The heat exchange circulation pump 15 and the heat exchange device 14 are provided in the cabinet 38 below the outer periphery of the placement platform of the immersion tank 4, and the heat exchange circulation pump 15 is provided on the short side of the frame 39, and the heat exchange device 14 is provided on the adjacent long side; the water outlet of the heat exchange circulation pump 15 is connected to the coolant inlet of the heat exchange device 14 through the pipeline system, and the solenoid valve 27, the water flow switch 23, the stop valve 25 and the pressure sensor 24 are provided in sequence on the pipeline system between the water outlet of the heat exchange circulation pump 15 and the coolant inlet of the heat exchange device 14, and the solenoid valve 27 is close to the heat exchange circulation pump 15. The water outlet side of the ring pump 15 is arranged; preferably, two heat exchange circulation pumps 15 are provided and mounted on the inner bottom of the frame 39 through a mounting plate. The water outlet ends of the two heat exchange circulation pumps 15 pass through a primary pipeline system composed of pipes, bellows, solenoid valves 27 and other equipment and are connected to a main pipe which is sequentially provided with a water flow switch 23, a stop valve 25 and a pressure sensor 24 through a tee. The other end of the main pipe is connected to the coolant inlet of the heat exchange device 14. In order to achieve stability, the main pipe is also supported on the inner bottom of the frame 39 by a supporting pipe clamp assembly; the coolant outlet of the heat exchange device 14 is connected to the coolant water supply pipe 13 through the coolant supply pipe 32.

[0063] The water inlet end of the heat exchange circulation pump 15 (the coolant recovery end side of the heat exchange system) is connected to the return pipe 11 through a pipe system; preferably, the water inlet end of each heat exchange circulation pump 15 (the coolant recovery end side of the heat exchange system) is connected to a pipe. To ensure safety and stability, these two pipes are supported on the inner bottom of the frame 39 through a pipe clamp assembly, and the two pipes are connected to the main pipe connected to the return pipe 11 through a tee.

[0064] When in use, after the heat exchange circulation pump 15 is started, the coolant outlet of the heat exchange device 14 transports the low-temperature coolant through the coolant supply pipe 32 to the coolant supply pipe 13, and then through multiple coolant supply branches with quick-connect ball valves 19 through the liquid distribution outlet 3 of the equalizing tank to the immersion tank 4 for heat exchange, taking away the heat generated by the components in the immersion tank 4. After the heat exchange, the coolant becomes a high-temperature coolant. At this time, the high-temperature coolant is transported to the immersion tank 4 through the outlet side of the immersion tank 4 under the action of the heat exchange circulation pump 15. The water enters the heat exchange circulation pump 15 from the water inlet of the heat exchange circulation pump 15 through the return pipe 11 equipped with a return pipe quick-connect ball valve 20 and the pipeline system, and then enters the heat exchange device 14 from the coolant inlet of the heat exchange device 14 through the water outlet of the heat exchange circulation pump 15 through the pipeline system equipped with an electric valve 27, a water flow switch 23, a stop valve 25 and a pressure sensor 24 to be cooled and transformed into low-temperature coolant. At this point, a circulation process is completed, and then the cycle is repeated to complete the heat dissipation operation of the components in the immersion tank 4.

[0065] Among them, the electric valve 27 can be used one-to-one with the heat exchange circulation pump 15. When the heat exchange circulation pump is started, the electric valve 27 is opened, and when the heat exchange circulation pump is shut down, the electric valve 27 is closed.
