Valve a22 is provided with outfall sewer 12.
Valve b23, valve c24, water quality treater 6, water pump 8 and valve d25 are respectively arranged with return main 7.
Rack-backplane heat exchanger combination sideboard 11, as shown in figure 3, include combination sideboard cabinet, combination sideboard cabinet it is relative two
Air inlet unit, wind unit are respectively arranged with side wall；Multiple servers 17 are disposed with combination sideboard cabinet from top to bottom,
Multiple servers 17 before wind unit with being provided with backplane heat exchanger 18.
Air inlet unit is made up of multiple air inlets set gradually from top to bottom.
Wind unit is made up of multiple air outlets set gradually from top to bottom；Fan is provided with each air outlet
19, set fan 19 that rack-air draft of backplane heat exchanger combination sideboard 11 can be made uniform, eliminate hot localised points.
Data center of the present invention is specific as follows with the course of work of fountain/phreatic water cooling system：
(1) during the broiling summer：
During the broiling summer, the cold water water temperature that only fountain cooling system provides can not meet the cooling need of data center 16
Ask, thus during the broiling summer the water in backplane heat exchanger 18 be fountain water 14 (being sprayed by main sprinkler part 21 and nozzle 3) and
The mixing water of phreatic water (being supplied phreatic water by phreatic water feed pipe 10).
In data center 16, the server 17 in each rack-backplane heat exchanger combination sideboard 11 distributes substantial amounts of heat,
In the presence of fan 19, the hot blast in rack-backplane heat exchanger combination sideboard 11 passes through the backplane heat exchanger 18 for being connected with cold water, heat
Wind is arranged into data center 16 after being cooled to cold air.
Absorbed after cold air in rack-backplane heat exchanger combination sideboard 11 after the heat of hot blast, the water in backplane heat exchanger 18
Temperature rise, the elevated water of temperature are returned in collecting-tank 4 by return main 7, effect of the water in collecting-tank 4 in fountain water pump 5
It is lower to be reached through water pipe 20 in feed pipe 2, water is injected into surrounding air to enter in the air by multiple nozzles 3 on feed pipe 2
Row heat exchange.
The heat exchange for being injected into aerial water and air is roughly divided into the following two kinds situation：
The first：When the temperature of water is higher than air themperature, heat transfer and evaporation all make heat be transmitted to air by water；
Second：When the temperature of water is less than air themperature, fed water although the quantity of heat convection is conducted heat by air, moisture steams
For the latent heat of vaporization of hair again with steam flow air, the long and is still that heat is transmitted to air by hot water, makes water temperature drop；
Cooled water is finally fallen back in fountain basin 1, and collecting-tank 4 is returned to after filter 13 carries out coarse filtration to water
In, because the principle of cold and hot layering, cooled water layer is distributed in the bottom of collecting-tank 4, and the of a relatively high water of temperature is then distributed
On the top of collecting-tank 4, get under the pressure effect of fountain water pump 5 and exchanged heat in the air with air, so constantly circulation；
And the water being cooled in collecting-tank 4 is then delivered in water quality treater 6 by return main 7, cold water and phreatic water after processing
After the phreatic water mixing of feed pipe 10, it is sent in the presence of water pump 8 in backplane heat exchanger 18 and is combined with rack-backplane heat exchanger
Hot-air in cabinet 11 is exchanged heat, and is completed the water temperature rise of heat exchange, is then sent back to collecting-tank 4 by outfall sewer 12, so
Constantly circulation.
(2) in transition season：
In transition season, fountain water 14 can undertake the refrigeration duty of data center 16 completely, so in spring and autumn transition season
It is the cooling of data center 16 only with fountain cooling system.
(3) in the winter time：
In the winter time, the temperature of fountain water 14 is too low, and data center 16 may be made dew condensation phenomenon occur and cause server 17 to damage
It is bad, so generally use phreatic water (providing phreatic water using phreatic water return pipe 9 and phreatic water feed pipe 10) is number in the winter time
Cooling is carried out according to center 16, closes fountain cooling system.
Data center of the present invention is sprayed with being provided with fountain cooling system, collecting-tank 4 in fountain/phreatic water cooling system
Spring cooling system is connected with collecting-tank 4, and collecting-tank 4 is connected with multiple cabinets-backplane heat exchanger combination sideboard 11 in data center 16.
During the broiling summer, when only fountain water 14 can not meet the cooling needs of data center 16, it is necessary to by fountain water 14 and phreatic water
It is passed through after mixing water in backplane heat exchanger 18, for reducing the temperature in data center 16；In transition season, backplane heat exchanger 18
In water be only fountain water 14 with regard to the cooling demand of data center 16 can be met, adequately achieve the utilization of natural cooling source；In the winter
Season, it is contemplated that icing phenomenon easily occurs in fountain water 14, and the long-term temperature substantially constant of phreatic water and temperature is relatively low, so the back of the body
Water in sheet heat exchanger 18 is then all provided by deep-well, makes full use of underground low-temperature receiver.Backplane heat exchanger 18 is blown out with server 17
Hot blast directly exchanged heat, heat by circulating chilled water be sent to it is outdoor radiated by fountain cooling system or recharge to
In deep-well, cooling heat exchange process is completed.
Data center of the present invention fountain/phreatic water cooling system, without disposing cooling tower, can be utilized in transition season
Natural cooling source, realize data center's green, energy-conservation and the requirement of environmental protection.
