Description

Technical Field

[0001] The present application relates to the field of waste heat recovery technology, and in particular to a heat treatment system, a cold distribution unit and a data center. Background Art

[0002] Data centers are energy-intensive industries. Most of the electricity consumed by IT equipment is converted into heat, generating a large amount of waste heat, which is directly discharged into the atmosphere, resulting in a waste of high-level energy. If waste heat is recycled, it can reduce carbon emissions or the use of high-quality energy, improve energy efficiency, reduce environmental pollution, and save energy costs. Liquid-cooled data centers have a higher cooling temperature. The water temperature on the secondary side of liquid cooling is higher than that on the primary side, which can provide waste heat at a higher temperature. The waste heat recovery efficiency is higher.

[0003] At present, the existing technology mainly sets a single heat exchange unit for heat recovery. When the waste heat is large, the waste heat recovery efficiency is low, and the waste heat generated by the data center cannot be fully utilized.

[0004] The secondary side of the cold plate liquid cooling system's cooling distribution unit has high water quality requirements. If the server connected to the secondary side is significantly modified, it involves the secondary side system modification, and the secondary side pipes need to be cleaned. If the cooling distribution unit is installed in the computer room, cleaning the secondary side pipes in the computer room will have a great impact on the other running equipment in the computer room.

[0060] Figure 6 A schematic diagram of the structure of a heat treatment system, a cooling distribution unit, a circulating pump and a control unit of a data center provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the heat treatment system provided in the embodiment of the present application includes: a first recovery unit 10, a first heat exchanger 11, a first heat exchange medium pipe 12, a second recovery unit 20, a second heat exchanger 21, a second heat exchange medium pipe 22, a heat source unit 30, a first heat source medium pipe 31, a second heat source medium pipe 32, a first heat source pipe 33, a second heat source pipe 34, a first control valve 35, a second control valve 36, a third control valve 37, a fourth control valve 38, a circulation pump 39, a cleaning unit 40, a clean water supply pipe 41, a clean water return pipe 42, a control unit 50, a controller 51, a first temperature sensor 52 and a second temperature sensor 53.

[0061] In the heat treatment system provided in the embodiment of the present application, a circulation pump 39 is arranged at the water supply end of the heat source unit 30 to promote the circulation of water in the pipeline, a first temperature sensor 52 is arranged at the water supply end of the first recovery unit 10, and a second temperature sensor 53 is arranged at the water supply end of the second recovery unit 20. The temperatures of the first temperature sensor 52 and the second temperature sensor 53 are compared with preset threshold values, and the opening and closing of the first control valve 35, the second control valve 36, the third control valve 37 and the fourth control valve 38 in the heat treatment system are controlled by the controller 51.

[0062] Specifically, when the first recovery unit 10 does not need to recover waste heat and the second recovery unit 20 recovers waste heat, the heat treatment system is in the first recovery state, and the second control valve 36 and the third control valve 37 are opened by the controller 51, so that the second recovery unit 20 is connected in series to the heat source unit 30, and the first recovery unit 10 is short-circuited and does not recover heat. The opening of the second control valve 36 is adjusted according to the temperature of the second temperature sensor 53 to ensure that the temperature of the second temperature sensor 53 reaches a preset threshold.

[0063] When the first recovery unit 10 needs to recover waste heat, and the second recovery unit 20 does not need to recover waste heat, the heat treatment system is in the fourth recovery state, and the first control valve 35 and the fourth control valve 38 are opened by the controller 51, so that the first recovery unit 10 is connected in series to the heat source unit 30, and the second recovery unit 20 is short-circuited and does not recover heat. The opening of the first control valve 35 is adjusted according to the temperature of the first temperature sensor 52 to ensure that the temperature of the first temperature sensor 52 reaches a preset threshold.

[0064] When both the first recovery unit 10 and the second recovery unit 20 need to recover waste heat, the heat treatment system is first in the third recovery state, and the first control valve 35 and the third control valve 37 are opened by the controller 51, so that the first recovery unit 10 and the second recovery unit 20 are connected in series to the heat source unit 30 to recover heat together. The opening of the first control valve 35 is adjusted according to the temperature of the first temperature sensor 52 to ensure that the temperature of the first temperature sensor 52 reaches the preset threshold, and then the opening of the third control valve 37 is adjusted according to the temperature of the second temperature sensor 53 to ensure that the temperature of the second temperature sensor 53 reaches the preset threshold. If the temperature of the second temperature sensor 53 is always lower than the preset temperature threshold, the second control valve 36 is opened by the controller 51. At this time, the heat treatment system is in the second recovery state, and part of the heat flowing through the second recovery unit 20 is recovered by the first recovery unit 10, and part is not recovered by the first recovery unit 10, which not only ensures that the first recovery unit 10 will not have no heat to recover, resulting in a temperature value lower than the preset threshold, but also increases the recoverable heat of the second recovery unit, so as to meet the heat requirements of the two recovery units at the same time as much as possible. The controller 51 then adjusts the openings of the first control valve 35 and the second control valve 36 to ensure that the temperatures of the first temperature sensor 52 and the second temperature sensor 53 reach a preset threshold.
