Hydraulic spray nozzle enhance the effect of cooling, the density of moderate hydraulic spray nozzle can play one's part to the full.In order to preferably be applicable in
In varying environment temperature, water mist sprinkling device 53 can be opened and closed switching.To sum up, spray heat exchange unit is simple in structure, for northwest
Regional and other remote, extremely frigid zones, whole year can meet computer room cooling requirement using natural wind, reduce to the full extent and are
System energy consumption.
Data center module cooling system work process be：The return air edge that the hot-air that 80 air side of cabinet sheds is formed
It the closing passage of heat 90 formed between the air side of two cabinets first to filter through chemical filtering unit 100, then enter through return air
Mouth enters return air channel and reaches heat-exchange device 50, into heat exchange of heat pipe 55.Meanwhile fresh air is introduced from Leads to new breeze pipe 60
Enter heat-exchange device 50 by fresh air inlet 51, after the filtering of filter 52, through 53 spraying cooling of water mist sprinkling device, cross and keep off
Enter heat exchange of heat pipe 55 after water plate 54, then in heat exchange of heat pipe 55, fresh air carries out heat exchange with return air.It is new after heat exchange
Wind leads to fresh air outlet 57 through wind turbine 56, and outdoor is excluded by fresh air discharge pipe 70.And the return air after exchanging heat is sent out through wind turbine 56
The both sides interlayer 30 of data center module is sent into return air outlet 59 by air supply duct 110, in the both sides interlayer 30 of data center module,
Return air is cooled down by dry coil pipe cooling unit 120, and the rear lower floor 40 for being sent into data center module is introduced to through floor blowing unit 130
Positioned at the inlet side 140 of the cabinet of data center module middle layer 20, cabinet is cooled down.
Space setting of the present invention is reasonable, and air current composition is reasonable, and air-supply accuracy is high, easily overhauls, and easily extends, simple in structure,
High-efficiency environment friendly, while also ensure the cleanliness factor of data center module.
