Placement, and water-collecting tray 104 can be avoided to be in contact with rack 1011.
In some optional implementations of the present embodiment, said flow conducting cover 103 can include being located at machine respectively
The Part I 1031 and Part II 1032 of the both sides of cabinet row 101, as shown in Figure 1 or 2.The first of air-flow conducting cover 103
Part 1031 and the passage of heat are located at the same side of rack row 101, and the Part II 1032 and cold passage of air-flow conducting cover 103 are located at
The opposite side of rack row 101, as shown in Figure 1 or 2.The inner side of the Part I 1031 of said flow conducting cover 103 is provided with more
Individual upward sawtooth, each upward sawtooth can be raised along the direction that cover 103 is turned on close to air-flow.In this way, upward sawtooth
Circulation of the air of passage of heat rising in air circulation path is not interfered with, and is caused when leakage occurs in chilled water coil 102
When current splash turns on the inner side of the Part I 1031 of cover 103 to air-flow, upward sawtooth can also change water flow jet
Direction, it is to avoid rack 1011 is drenched.The inner side of the Part II 1032 of said flow conducting cover 103 is provided with multiple downward saws
Tooth, each downward sawtooth can be raised along the direction that cover 103 is turned on away from air-flow.Similarly, downward sawtooth is not interfered with
Circulation of the cold air that cold passage declines in air circulation path, and cause current spray when leakage occurs in chilled water coil 102
During the inner side for the Part II 1032 for splashing air-flow conducting cover 103, downward sawtooth can also change the direction of water flow jet, keep away
Each rack 1011 for exempting to be disposed below is drenched.It is appreciated that the Part I 1031 and second of said flow conducting cover 103
Part 1032 can be inseparable entirety, or air-flow conducting cover 103 can be by Part I 1031 and Part II
1032 compositions, and Part I 1031 and Part II 1032 are respectively an entirety.
The refrigeration system for the data center that above-described embodiment of the application is provided, can include rack unit, refrigeration unit
And waterproof unit, refrigeration unit is including being used for the chilled water coil 102 that cooling machine cabinet row are dispersed into the air of the passage of heat, refrigeration unit
It is arranged on above rack row 101, waterproof unit includes being located at the air-flow conducting cover of chilled water coil 102 and the top of rack row 101
103, air-flow conducting cover 103 forms air circulation path with cold passage and the passage of heat, it is seen that air-flow conducting cover 103 can aid in gas
Conductance leads to, and air-flow conducting cover 103 can control the direction of current when chilled water coil 102 is leaked, and prevent current from spraying
Splash on rack row 101, reduce data center's flood risk, improve data center's reliability.
With continued reference to Fig. 3, it illustrates the knot of another embodiment of the refrigeration system of the data center according to the application
Structure schematic diagram.
In the present embodiment, can be with same as the previously described embodiments, the refrigeration system of data center can also include rack list
Member, refrigeration unit and waterproof unit.As shown in figure 1, above-mentioned rack unit can include rack row 101, each rack row 101 can be with
Including multiple racks 1011 arranged along column direction.Above-mentioned refrigeration unit can be arranged on the top of each rack row 101, for for
Each rack 1011 in data center is cooled.Here refrigeration unit can be overhead type refrigeration unit, the refrigeration unit
Chilled water coil 102 is provided with the top of each rack row 101, rack row 101 can be dispersed into the sky of the passage of heat by chilled water coil 102
The rack row 101 under the chilled water coil 102 are output to from cold passage after gas cooling.Pass through chilled water coil 102 in cold passage
The air of cooling can reduce the temperature of each rack 1011 in rack row 101, so that the refrigeration unit of data center can be with
It is embodied as the purpose of data center's cooling.Above-mentioned waterproof unit can include air-flow conducting cover 103, and air-flow conducting cover 103 covers
It is located at the top of chilled water coil 102 and rack row 101.Air-flow conducting cover 103 is identically formed air with the passage of heat and cold passage and followed
Endless path so that the hot-air that rack row 101 are produced is exported through the passage of heat, chilled water coil 102 cools, then by cold passage again
It is output to rack row 101, it is seen that air-flow conducting cover 103 can avoid the region beyond hot-air emitting air circulating path, auxiliary
The conducting of air-flow is helped.Also, when leakage splash cold water occurs for chilled water coil 102, said flow conducting cover 103 can be with
The injection direction for the water that control chilled water coil 102 is leaked out, it is to avoid because the water jet length leaked out is big, drench with being located under it
The adjacent rack row 101 of square rack row 101.
In the present embodiment, above-mentioned waterproof unit can also include leakage inspector 105, as shown in figure 3, the leak is examined
Leak water detdction rope and water leak detectors can be included by surveying device 105, and water leak detectors can be electrically connected with leak water detdction rope,
