Description

Technical Field

[0001] The present invention relates to the fields of 5G BBU cooling technology, and specifically, to a 5G BBU single-phase immersion liquid cooling cabinet. Background Art

[0002] The "Information and Communication Industry Green and Low-Carbon Development Action Plan (2022-2025)" jointly issued by the Ministry of Industry and Information Technology and other seven departments in August 2022 mentioned: "By 2025, the power utilization efficiency (PUE) of newly built large and ultra-large data centers nationwide will be reduced to below 1.3." "Improve the energy efficiency level of IT facilities. Actively apply liquid-cooled and high-temperature IT equipment to improve the energy efficiency of IT equipment in data centers." Among them, the 5G BBU immersion liquid cooling cabinet belongs to data center liquid cooling. The current existing technologies or patents include cold plate liquid cooling, single-phase immersion liquid cooling, two-phase immersion liquid cooling, air cooling, etc.; Immersion liquid cooling has lower PUE than cold plate liquid cooling and air cooling, higher power saving rate, and occupies less space; two-phase immersion liquid cooling requires specially sealed pressure vessels compared to single-phase immersion liquid cooling and is not conducive to online maintenance.

[0003] The current single-phase immersion liquid cooling system is generally composed of an independently set immersion cabinet and a heat exchange system. The immersion cabinet mainly includes a cabinet and an immersion tank, and the heat exchange system is loaded with an independent CDU. Since the two are set separately, there is a problem of occupying a large space.

[0004] Moreover, in the existing single-phase immersion liquid cooling technology, the immersion pools are different, the immersion objects and the immersion quantities 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 appearance of the immersion liquid cooling cabinet. The smaller the volume of the immersion liquid cooling cabinet, the more convenient it is for later installation and maintenance.

[0005] At present, the immersion tank of the single-phase immersion liquid cooling system has the problem of large volume, and is not well compatible with weak current and optical fiber wiring space, and is not very convenient for online maintenance. The integration of the liquid separation device is not ideal.

[0006] At present, the liquid separation device in the immersion tank of the single-phase immersion liquid cooling system is usually an integral and 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.

[0007] The use of the above liquid separation device causes the flow rate of the single-phase coolant between each 5G BBU to be different and uneven in each 5G BBU. The heat emitted by each 5G BBU cannot be taken away evenly and in time, resulting in a large temperature difference between the single-phase coolant of each 5G BBU and a large temperature difference in the working environment of the 5G BBU.

[0053] Among them, the liquid cooling water inlet system includes a coolant water supply water pipe 13, on which a plurality of coolant water supply branches with quick-connect ball valves 19 are arranged through three-way pipe fittings, and the outlets of the plurality of coolant water supply branches are connected to the water inlet side of the immersion tank 4 by means of elbows, and the inlet of the coolant water supply water pipe 13 is connected to the coolant outlet end side of the heat exchange system; the liquid cooling return water system includes a return water pipe 11 provided with a return water pipe quick-connect ball valve 20, one end of the return water pipe 11 is connected to the water outlet side of the immersion tank 4 through an elbow, and the other end of the return water pipe 11 is connected to the coolant recovery end side of the heat exchange system.

[0054] During use, the coolant used for cooling is cooled by the heat exchange system to obtain low-temperature coolant.

[0056] 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 arranged 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 arranged on the short side of the frame 39, and the heat exchange device 14 is arranged 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 arranged 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 arranged and installed 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 provided with a water flow switch 23, a stop valve 25 and a pressure sensor 24 in sequence through a tee.
