First the air (i.e. data center's hot-air) cooled by needs enters via data center's hot air inlet 2 First via air flow circuit thus circulate send into indirect evaporation heat exchange module 5 several polymer pipelines 501 in, drenched by outside Water (i.e. coordinates several rotary spray heads 601 of spray thrower 6, is rotation spray as shown in the solid drops stain in Fig. 5 Drench water for 601 sprays) realize data center's hot-air and indirectly lower the temperature (i.e. equal-enthalpy humidifying evaporation cooling), evaporation moisture film is attached to Outside polymer pipeline 501 tube wall, accelerate the heat exchange of the air (i.e. outdoor air) outside with it, polymer pipeline in addition 501 by the bulge-structure 5011 arranged on its outer wall, increases heat exchange area, improves heat exchange efficiency further, thus obtains more Low gas temperature, the cold air after the house data i.e. heat exchange of central hot air of final cooled cooling is sent in data Interior portion heat exchange；Meanwhile, another road outdoor air (low outside air) flows through the outer surface of indirect evaporation heat exchange module 5 (i.e. Each polymer pipeline 501 outer surface), coordinate the humidified intensification of spray thrower 6 by indirect evaporation heat exchange module 5, indirect evaporation changes The cooled cooling of water of the outer surface of thermal modules 5 and spray thrower 6 spray, and then the data of indirect evaporation heat exchange module 5 will be entered Central hot air cools, the temperature difference of two-way air after further increase processes, and that is to say the heat of the data center after process The temperature difference of the two-way air being expelled to outdoor after air i.e. cold air and process, this temperature difference can reach 10～15 degree, improves Cooling heat transferring efficiency.When indirect evaporation heat exchange module 5 is properly functioning, its hull-skin temperature is typically not above 30 degree, logical Rapid and a large amount of fouling of Chang Buhui, the tubule being generally set to 2 meters of how long polymer pipelines 501 operationally can produce Slight vibrations (i.e. two strands of air-flows of indoor and outdoor two-way air high velocity stream movable property inside and outside polymer pipeline 501 tube wall Raw slight vibrations) the thin layer incrustation scale entirety being attached to polymer pipeline 501 outer surface of tube wall is shaken off, so that indirect evaporation Heat exchange module 5 can be constantly in safe, reliable, efficient duty, keeps heat exchanger effectiveness to be in higher shape for a long time State.

The operation principle of the polymer indirect evaporation type data center cooling system that this utility model relates to illustrate as Under:

First it is described as follows: the polymer indirect evaporation type data center cooling system that this utility model relates to uses indirectly Natural cooling mode is to realize the data center cooling system of low-power consumption.1) when outdoor environment is colder when, the method for operation is Air-air heat exchange method, only carries out the cooling process of data center's inner air, i.e. by outdoor relatively low air themperature The most natural type of cooling；2) when outdoor environment relatively warms up when, the method for operation is indirect evaporating-cooling mode, utilizes air Water suction cool principle, maximally utilises outdoor natural cooling source and carries out the cooling process of data center's inner air；3) room is worked as The when of external environment hot humid, the method for operation is that indirect evaporating-cooling mode is in combination with direc expansion refrigeration mode.Directly Swell refrigeration circulation only provides the part refrigerating capacity that indirect evaporating-cooling is not enough.Direc expansion refrigeration can use traditional direct Expansion refrigeration system, it is possible to substituted by chilled water Surface cooling coil.

Above-mentioned latter two type of cooling operation principle is described as follows:

I) indirect evaporating-cooling mode

Interior Space air-flow (sees filled arrows direction in Fig. 1 and Fig. 3):

Hot-air within data center, enters from data center's hot air inlet 2, through the first air filter 3 mistake After filter, sucked pressurization by the first air blower 4 and deliver to indirect evaporation heat exchange module 5 and carry out cooling to presetting temperature After, it is admitted to inside data center carry out heat exchange cooling from cold-air vent 7.

Flow of outside air (sees Fig. 1 and Fig. 3 hollow core direction of arrow):

Ambient outdoor air enters from outdoor air inlet 8, is filtered by the second air filter 9, enters indirect evaporation and changes Thermal modules 5 region is sprayed equal-enthalpy humidifying cooling, and by the data in the polymer pipeline 501 of indirect evaporation heat exchange module 5 Heat in the heart air cools down, and the outdoor air of heated humidification is sucked from outdoor air outlet 11 is expelled to by the second air blower 10 Boundary.

II) indirect evaporating-cooling mode is in combination with direc expansion refrigeration mode

Interior Space air-flow (sees in Fig. 1 and Fig. 3 the horizontal direction of arrow in filled arrows direction and Fig. 7):

Hot-air within data center, enters from data center's hot air inlet 2 (i.e. A point Fig. 7), through first After air filter 3 (i.e. B point in Fig. 7) filters, sucked pressurization by the first air blower 4 (i.e. C point in Fig. 7) and deliver to indirectly Evaporation and heat-exchange module 5 carries out cool (i.e. D point in Fig. 7), is then fed into vaporizer 1302 (i.e. evaporation coil) and continues Cooling (i.e. E point in Fig. 7) (i.e. according to extraneous meteorological condition such as when the outdoor environment hot humid when, and is being steamed indirectly When sending out heat exchange module 5 refrigerating capacity deficiency, open refrigeration mechanism SAPMAC method with supplementary indirect evaporation heat exchange module 5 sweat cooling not The part of foot) to after presetting temperature, it is admitted to inside data center carry out heat exchange cooling from cold-air vent 7.

Flow of outside air (sees vertical arrows direction in Fig. 1 and Fig. 3 hollow core direction of arrow and Fig. 7):

Ambient outdoor air enters from outdoor air inlet 8 (i.e. F point Fig. 7), by second air filter 9 (i.e. Fig. 7 In G point) filter, enter indirect evaporation heat exchange module 5 region sprayed equal-enthalpy humidifying cooling (i.e. H point in Fig. 7), and will between Connecing the data center's hot-air cooling in the polymer pipeline 501 of evaporation and heat-exchange module 5, the outdoor air of heated humidification enters Condenser 1303 (i.e. I point in Fig. 7), after the heat in compression mechanism SAPMAC method in absorptive condenser 1303, by second Air blower 10 (i.e. J point in Fig. 7) sucks and is discharged outside to from outdoor air outlet 11.
