Description

Technical Field

[0001] The utility model relates to the technical field of data centers, in particular to an intelligent cold source control system for building refrigeration in a data center. Background Art

[0002] With the rapid development of information technology, the scale of data centers continues to expand. Today, data centers house a large number of servers, which generate significant amounts of heat during operation. For example, a large internet company's data center may have tens of thousands of servers running simultaneously, each acting as a small heat source.

[0003] Traditional data center cooling systems often adopt extensive cooling methods. Some cooling systems using large air-conditioning units operate at a fixed power regardless of the actual load and heat generation of the server. This results in the cooling system still consuming a large amount of electricity when the server load is low, resulting in energy waste. Moreover, if the server overheats during the cooling process, a single cooling method cannot achieve efficient cooling. Therefore, to address the above problems, an intelligent cold source control system for data center building cooling is proposed. Utility Model Content

[0004] The purpose of the present invention is to provide an intelligent cold source control system for data center building refrigeration to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

An external pipe is provided on the connecting pipe, and the external pipe is connected to the bottom pipe port of the annular heat exchange tube. Both the external pipe and the connecting pipe are provided with switch valves. The discharge port of the water pump is connected to the cold source feed port of the server group, and a discharge pipe is provided on the cold source discharge port of the server group.

[0009] A return box is set at the bottom of the data center building, and the discharge pipe is connected to the return box through a pipeline. The return box is provided with a supply pump with a pumping pipe extending into the return box, and the discharge port of the supply pump is connected to the material box through the return pipe.

[0010] As a preferred solution, an air-cooled radiator is provided on the return pipe.

[0011] As a preferred solution, a semiconductor refrigeration sheet is attached to the inner wall of the refrigeration ring-shaped water tank, and a heat sink is attached to the hot end of the semiconductor refrigeration sheet.

The water pump 13 plays a key role in promoting the flow of coolant in the refrigeration cycle.

[0038] Refrigeration water tank 14:

[0039] Located at the top of the chassis 11, the inner wall of the chassis 11 defines a cavity 141, within which an annular heat exchange tube 146 is disposed.

[0040] The inner wall is attached to the semiconductor refrigeration sheet 142, and the hot end of the semiconductor refrigeration sheet 142 is attached to the heat sink 143; the semiconductor refrigeration sheet 142 reduces the temperature of the coolant in the refrigeration ring-shaped water tank 14 through the refrigeration effect, and the heat sink 143 helps to dissipate the heat at the hot end of the semiconductor refrigeration sheet 142;

[0041] Air inlets 16 are provided on the front and rear side panels of the bottom. A fan mounting bracket 144 is provided above the bottom air inlet 16. A cooling fan 145 is provided on the fan mounting bracket 144. The cooling fan 145 can introduce air through the air inlet 16 to enhance the heat dissipation effect of the heat sink 143.

[0042] Server Group 17:

[0043] The outlet of the water pump 13 is connected to the cold source inlet of the server group 17, and the cold source outlet of the server group 17 is provided with a discharge pipe 18; the coolant performs heat exchange in the server group 17, taking away the heat generated by the server;

[0044] Reflux box 4:

[0045] Located at the bottom of the data center building, the discharge pipe 18 is connected to it through a pipeline; the return box 4 is equipped with a pumping pipe and a supply pump 5, and the discharge port of the supply pump 5 is connected to the material box 2 through the return pipe 6; the return box 4 collects the coolant flowing out of the server group 17, and the supply pump 5 pumps the coolant in the return box 4 back to the material box 2, completing the refrigeration cycle;

[0048] 2. Working Principle

[0049] Cold source supply stage:

[0050] The coolant in the material tank 2 passes through the supply pipe 3 and the feed pipe 15 into the annular heat exchange tube 146 in the refrigeration loop water tank 14. In the refrigeration loop water tank 14, the semiconductor refrigeration plate 142 works to lower the temperature inside the water tank. At the same time, the cooling fan 145 and the heat sink 143 work together to dissipate the heat from the hot end of the semiconductor refrigeration plate 142, thereby preliminarily cooling the coolant in the annular heat exchange tube 146.

[0051] When the coolant needs to be supplied to the server group 17, the water pump 13 pumps the preliminarily cooled coolant from the annular heat exchange pipe 146 through the control of the switch valve on the connecting pipe 19 and the external pipe, and delivers it to the cold source inlet of the server group 17 through the outlet of the water pump 13;

[0052] Server group cooling stage:

[0053] After the coolant enters the server group 17, it exchanges heat with the heat generated by the server, and the coolant temperature rises, taking away the heat generated by the server;

[0054] Coolant return stage:

[0055] The high-temperature coolant flowing out from the cold source outlet of the server group 17 enters the return box 4 through the discharge pipe 18; the supply pump 5 in the return box 4 extracts the coolant and returns it to the material box 2 through the return pipe 6; on the return pipe 6, the air-cooled radiator 7 dissipates heat from the high-temperature coolant, lowering the coolant temperature so that the coolant can re-enter the refrigeration cycle and be reused for cooling.

[0056] In this embodiment, the water pump 13 and the switch valve on the connecting pipe 19 in the same refrigeration mechanism 1 are connected to the corresponding relays in the relay group 12, and the cooling fan 145 and the semiconductor cooling plate 142 are connected to the corresponding relays in the relay group 12;

[0057] In this embodiment, a temperature sensor is also provided on the discharge pipe 18 and a control terminal of the data center building. When the data center building is in operation, the control terminal controls the supply pump 5, the fan radiator 7, the water pump 13 and the switch valve on the connecting pipe 19 to open synchronously to achieve normal cooling of the data center building.

[0058] When the temperature sensor on the discharge pipe 18 in the refrigeration mechanism 1 detects that the temperature exceeds the threshold, the switch valve on the connecting pipe 19 of the refrigeration mechanism 1 is closed, and at the same time, the cooling fan 145, the semiconductor refrigeration plate 142 and the switch valve on the external pipe are opened, and the semiconductor refrigeration plate 142 is used to enhance the cooling of the refrigerant to improve the cooling efficiency of the refrigerant.

[0059] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
