[0026] See also Figure 1 The embodiment of the utility model provides a data center heat recovery system, which specifically includes a heat extraction component, a first heat exchange component, a data center side water supply component, a second heat exchange component and a user side water supply component; wherein,

[0027] The heat extraction component is connected to the data cabinet in the data center and is used to transfer the heat generated by the data cabinet to the first heat exchange component; the heat extraction component includes a heat extraction cover, each data cabinet is provided with a heat extraction cover, the heat extraction cover is connected to the first heat exchange component through a hot air delivery pipeline, and a blower is provided on the hot air delivery pipeline.

[0028] The first heat exchange component is connected to the heat extraction component and the data center side water supply component respectively, and is used to receive the cold water generated by the data cabinet and in the data center side water supply component, and perform heat exchange so that the cold water in the data center side water supply component absorbs heat and is converted into warm water.

[0029] Specifically, the first heat exchange component is a steam-water heat exchanger, and the heat generated by the data cabinet is heat-exchanged with the cold water in the water supply component on the data center side inside the steam-water heat exchanger, and the cold water absorbs the heat generated by the data cabinet and is converted into warm water.

[0030] The data center side water supply component is connected to the first heat exchange component and the second heat exchange component respectively, and is used to send the cold water in the data center side water supply component to the first heat exchange component, and receive the warm water and send it to the second heat exchange component.

[0031] The water supply component on the data center side includes a first return water pipeline, a first water supply pipeline and a first circulation pump. The first return water pipeline sends the cold water in the water supply component on the data center side into the first heat exchange component. The cold water is converted into warm water after heat exchange with the heat generated by the data cabinet through the first heat exchange component. The warm water enters the second heat exchange component through the first water supply pipeline. The warm water after the heat exchange is converted into cold water. The cold water enters the first heat exchange component again through the first return water pipeline for circulation. The first circulation pump can be located on the first return water pipeline or the first water supply pipeline to provide power for the water circulation in the first return water pipeline and the first water supply pipeline.

[0032] The second heat exchange component is connected to the data center side water supply component and the user side water supply component respectively, and is used to receive the warm water and the cold water in the user side water supply component, and perform heat exchange, so that the cold water in the user side water supply component absorbs heat and is converted into hot water, and is supplied to the user end for use.

[0033] Specifically, the second heat exchange component is a heat pump unit, which extracts heat from the warm water and transfers the extracted heat to the cold water in the user-side water supply component, so that the cold water in the user-side water supply component is converted into hot water.

[0034] The user-side water supply component is connected to the second heat exchange component and the user end respectively, and is used to receive the hot water and supply it to the user end for use.

[0035] Specifically, the user-side water supply component includes a second return water pipeline, a second water supply pipeline and a second circulation pump. The second return water pipeline delivers the cold water in the user-side water supply component into the second heat exchange component. The cold water becomes hot water after heat exchange with the warm water through the second heat exchange component. The hot water enters the user end through the second water supply pipeline to be used, and after the heat is consumed on the user side, it becomes cold water again. The cold water enters the second heat exchange component again through the second return water pipeline for circulation. The second circulation pump can be located on the second return water pipeline or the second water supply pipeline to provide power for the water circulation in the second return water pipeline and the second water supply pipeline.

[0036] Furthermore, the water supply component on the data center side also includes a first water treatment device, which is connected to the first return water pipeline through a first make-up water pipeline, and a first make-up water pump is installed on the first make-up water pipeline; the first water treatment device is connected to an external water source, and when the water supply component on the data center side leaks, the treated water that meets the standards is sent to the first return water pipeline through the first make-up water pipeline to ensure full water operation and avoid insufficient heat exchange due to insufficient water; in addition, the initial water volume in the water supply component on the data center side is also provided by the first water treatment device.

[0038] In addition, a heat dissipation pipeline is connected to the steam-water heat exchanger, and the heat dissipation pipeline is connected to the outside of the data center. An exhaust fan is installed on the heat dissipation pipeline. After the heat generated by the data cabinet and the cold water in the water supply component on the data center side are heat exchanged, the residual heat that is not absorbed is sent to the outside from the heat dissipation pipeline through the exhaust fan.

[0039] The specific working principle of the data center heat recovery system is as follows:

[0040] A heat collecting hood is arranged at the heat dissipation end of the data cabinet to collect the waste heat of the data cabinet, and then the waste heat is collected and sent to the steam-water heat exchanger arranged in the computer room of the data center through the hot air transmission pipeline and the blower. After heat exchange with the cold water sent by the water supply component on the data center side, the waste heat that has not been exchanged is discharged to the outside through the heat dissipation pipeline, thereby reducing the indoor temperature of the data center and ensuring the normal operation of the equipment; the cold water in the first return water pipeline of the water supply component on the data center side absorbs heat and is converted into warm water, which is sent to the heat pump unit by the first water supply pipeline and the first circulation pump; at the same time, the second return water pipeline in the water supply component on the user side sends the cold water in the water supply component on the user side into the heat pump unit, and the warm water is heat exchanged and converted into hot water that meets the user's heating temperature, and is sent to the user end for use through the second water supply pipeline, and after the heat is consumed on the user side, the cooled cold water is sent to the heat pump unit through the second water supply pipeline and the second circulation pump for reheating, and this reciprocating cycle is repeated to continuously supply heat to the user.
