Description
Technical field
The present invention relates to a kind of room air cooling system more particularly to a kind of cooling systems of data center module.
Background technology
Now with cloud computing, the development of the technologies such as big data application, the construction requirements of data center module are higher and higher.Data
Computer room is made of many electronics and electromechanical facility.In these equipment, a large amount of integrated circuit and electronic component have been used, it
Have particular requirement to use environment, otherwise can influence its service life and operational reliability.The host of computer system is being transported
A large amount of heat dissipations during row, if cannot heat extraction in time temperature in cabinet or computer room will be caused to improve rapidly, influence computer
Steady operation.Therefore, cooling system is the important component of data center module.
Application No. is the patents of CN201510274184.5 to disclose a kind of data center water hot and cold tube cooling system and side
Method.Data center is separated into top cabinet space and lower part refrigeration space, the cabinet by the cooling system by raised flooring
It is arranged in columns, and is repeated in setting closing cold passage and the closing passage of heat between cabinet.Heat pipe heat exchanging unit is placed in corresponding
Cabinet lower part refrigeration space, logical supercooled liquid dispenser unit exchange heat with freezing water unit.Heat pipe described in the invention
Heat exchange unit is not take up cabinet space, and equipment enclosure density can be improved, and has advantage in the setting in data center module space, but still
It has the following defects：First, the air supply mode of the invention is to be sent to Cryogenic air in cabinet from bottom, absorbs the heat of cabinet
Afterwards, return to lower part refrigeration space from the bottom of cabinet, the direction of hot wind flow be from the top of cabinet to lower part refrigeration space, by
Light in hot-air, with its characteristic on the contrary, air supply efficiency reduces, energy consumption increases in hot wind flow direction.Secondly, in data center module,
Floor is mainly to arrange various types of communication pipeline to cabinet, and in the early stage, communication apparatus is few, and pipeline is few, and starts the cloth of pipeline
It is also in good order to set, and can accommodate the lower part refrigerating plant normal work of the invention, but with the continuous dilatation of engineering,
Equipment installation is more and more, possibly can not ensure the kilter of lower part refrigeration space.Finally, the heat pipe heat exchanging in lower space
Unit is all disposed in raised flooring, is not easy to find when ging wrong, is in turn resulted in security risk, this is unfavorable to safety in production
's.Above defect can be solved by rearranging data center module space.
Invention content
In view of this, it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of spaces, and rational number is arranged
According to the cooling system of computer room.
A kind of cooling system of data center module, including Leads to new breeze pipe and fresh air discharge pipe, Leads to new breeze pipe are arranged with fresh air
Outlet pipe is set to the upper layer of data center module, and the heat-exchange system by being set to upper layer is connected to, data center module both sides sandwich shape
At cold passage, cold passage upper end is connected to heat-exchange system, and lower end is connected to the cold passage of data center module lower layer, the centre of data center module
Layer is provided with stack of cabinets, and stack of cabinets is made of two cabinets, and two cabinet air sides are in being oppositely arranged, in going out for two cabinets
The closing passage of heat is formed between wind side, every closing passage of heat is connected to heat-exchange system, and the inlet side of each cabinet is formed
Cold passage, data center module lower layer are connected to the inlet side of each cabinet through floor blowing unit.
The present invention makes full use of the space of data center module, and data center module is divided into upper layer, both sides interlayer, lower layer, and handle
These channels are combined with cold and hot air-supply passage.In the work course, fresh air enters heat-exchange system from Leads to new breeze pipe, together
When, cabinet air side sheds heat, and the return air of formation enters heat-exchange system along the closing passage of heat.In heat-exchange system, return
Wind carries out heat exchange with fresh air, and the fresh air after heat exchange is expelled to outdoor through fresh air discharge pipe, and the return air after heat exchange enters modem
The cold passage of room both sides interlayer and lower layer is introduced to the inlet side of the cabinet of data center module middle layer through floor blowing unit, right
Cabinet is cooled down.One cycle is completed.In whole work process, Cryogenic air is sent to from bottom in cabinet, high temperature air
Enter heat-exchange system from enclosure top.The direction of wind flow and the characteristic of air are consistent in system, and air current composition is reasonable, send
