Description

TECHNICAL FIELD

[0001] The utility model relates to 5G BBU cooling technology fields, specifically, it is a kind of 8 5GBBU immersion heat exchange system. BACKGROUND

[0002] In August 2022, the Ministry of Industry and Information Technology and other seven departments jointly issued "Information Communication Industry Green Low-carbon Development Action Plan (2022-2025)", which states: "By 2025, the national new large and super large data center power utilization efficiency (PUE) will be reduced to 1.3 or less.", "Improve the energy efficiency of IT facilities. Actively apply liquid cooling type, high temperature type IT equipment to improve the energy efficiency of data center IT equipment." The 5G BBU immersion liquid cooling cabinet belongs to the data center liquid cooling, and the existing technology or patent has cold plate type liquid cooling, single-phase immersion liquid cooling, double-phase immersion liquid cooling, air cooling, etc.

[0003] The immersion liquid cooling is lower than the cold plate type liquid cooling and air cooling in PUE, and has higher power saving rate and smaller occupied space; the double-phase immersion liquid cooling needs special sealing pressure vessel and is not conducive to online maintenance compared with the single-phase immersion liquid cooling.

[0004] The current single-phase immersion liquid cooling system is generally composed of an independently arranged immersion cabinet and a heat exchange system, the immersion cabinet mainly includes a cabinet frame and an immersion pool, and the heat exchange system adopts an independent CDU loading. Since the two are independently arranged, there is a problem of large occupied space.

[0005] In addition, in the existing single-phase immersion liquid cooling technology, the immersion pools are different, the immersion objects are different, the immersion quantities are different, the wiring methods of weak current and optical fiber are different, and the convenience of maintenance is different. For the operation of 5G BBU, online maintenance is the best and cannot affect 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 conducive to the installation and maintenance in the later period.

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

[0007] In addition, the liquid separation device in the immersion pool of the current single-phase immersion liquid cooling system is usually a whole type sealed liquid separation cavity. The single-phase cooling liquid after cooling is injected into the liquid separation cavity through a circulating pump, and a single hole is opened on the inside of the liquid separation cavity corresponding to each 5G BBU, so that the cooling liquid is sprayed to each 5G BBU through the small hole.

[0008] The above liquid separation device causes the flow of single-phase cooling liquid among the 5G BBUs to be uneven and different in each 5G BBU, and the heat emitted by each 5G BBU cannot be uniformly and timely taken away, resulting in a large temperature difference of the single-phase cooling liquid among the 5G BBUs and a large temperature difference in the working environment of the 5G BBUs.

[0051] Example 1:

[0052] An 8 5G BBU immersion heat exchange system is arranged in a single-phase immersion liquid cooling cabinet, integrates the heat exchange system and the immersion pool, so that it can be fully loaded by using the liquid cooling cabinet, thereby providing a feasible solution for designing an integrated single-phase immersion liquid cooling machine, as shown in Figures 1-10 As shown, it comprises a heat exchange system, a liquid cooling water inlet system, a liquid cooling water return system and an immersion pool 4; the liquid cooling water inlet system comprises a cooling liquid water supply pipe 13, a plurality of cooling liquid water supply branches with quick-connection ball valves 19 are arranged on the cooling liquid water supply pipe 13, and the plurality of cooling liquid water supply branches are connected to the water inlet side of the immersion pool 4, and the cooling liquid water supply pipe 13 is connected to the heat exchange system; the liquid cooling water return system comprises a water return pipe 11 provided with a water return pipe quick-connection ball valve 20, one end of the water return pipe 11 is connected to the water outlet side of the immersion pool 4, and the other end of the water return pipe 11 is connected to the heat exchange system.

[0053] As a preferred design scheme, the 8 5G BBU immersion heat exchange system comprises a heat exchange system for cooling the cooling liquid; a liquid cooling water inlet system for delivering the cooled cooling liquid into the immersion pool 4 to take away the heat of the 5G BBU; a liquid cooling water return system for outputting the high-temperature cooling liquid after taking away the heat of the 5G BBU through the immersion pool 4 into the heat exchange system for cooling again.

[0054] The liquid cooling water inlet system comprises a cooling liquid water supply pipe 13, a plurality of cooling liquid water supply branches with quick-connection ball valves 19 are arranged on the cooling liquid water supply pipe 13 through a tee pipe fitting, etc., and the outlets of the plurality of cooling liquid water supply branches are connected to the water inlet side of the immersion pool 4 through an elbow, and the inlet of the cooling liquid water supply pipe 13 is connected to the cooling liquid outlet end side of the heat exchange system; the liquid cooling water return system comprises a water return pipe 11 provided with a water return pipe quick-connection ball valve 20, one end of the water return pipe 11 is connected to the water outlet side of the immersion pool 4 through an elbow, and the other end of the water return pipe 11 is connected to the cooling liquid recovery end side of the heat exchange system.

[0060] 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.
