Plate, the baffle and fairing are arranged in cold duct, the porous plate is arranged on the air outlet for cold duct, institute
Fairing is stated for being integrated into the flow field of data center floor；First order zoned air system can be every group according to data center
Semen donors needed for the flux matched every group of cabinet of heat dissipation of cabinet.Zoned air system in the second level includes the sky being made of heat-barrier material
Mesosome and the adjustable layering porous plate of percent opening for being arranged in space body side, the layering porous plate are every according to every group of cabinet
The heat production feature of layer divides multilayer, to match the heat dissipation capacity of every group of every layer of cabinet.The system further includes in addition to this, temperature sensing dress
It puts, return air inlet.The temperature sensing device is arranged in around every group of cabinet, to real-time measuring unit temperature.Return air inlet
Ceiling is arranged in, a part of return air can be mixed with fresh air and be blown, and save energy expenditure.
Preferably, the first order zoned air system is useful for providing the pressure fan of cold air.
Preferably, each subregion in first order partition system has an individual cooling pipeline, the baffle in cooling pipeline
Angle adjustable.Individual cooling pipeline can individually match the cold being corresponding to it needed for cooling machine cabinet, and cold air is adjusted in baffle
Amount.
Preferably, the porous packing free ratio of floor outlets is adjustable in first order partition system, plays rectification and control
The effect of flow velocity improves cooling effect.
Preferably, in the partition system of the second level, number of partitions is identical with every group of cabinet number of plies, and every group of every layer of cabinet is pacified
Equipped with temperature sensing device.
Preferably, in the partition system of the second level, the cold of each subregion is controlled by the adjustable porous plate of percent opening.
Preferably, data center's top layout return air inlet.A small amount of return air of return air inlet is mixed with fresh air, is made
Cold wind is sent into interior, can be effectively energy saving.
Present invention advantageous effect compared with the prior art is：The present invention according to the heat production feature of cabinet, subregion by cold
Every group of cabinet is supplied, and according to the heat dissipation feature of every group of every layer of cabinet, cold has been subjected to reasonable distribution again.It effectively raises
