According to the cooling device, a ventilating structure is arranged below the packaged door cabinet, and the cooling device is located below the closed-door cabinet. The cooling device comprises a floor level grill, an air generating unit and a control unit, wherein the floor level grill is located on the surface, close to the ventilating structure, of the cooling device, and there is an overlapped area between the floor level grill and the ventilating structure; the air generating unit is located below the floor level grill; the control unit controls the air generating power of the air generating unit to cool the closed-door cabinet. Due to the cooling device is arranged below the closed-door machine, cold air generated by the air generating unit in the cooling device can enter the closed-door cabinet, and therefore heat of devices of the closed-door cabinet can be evenly dissipated, generation of local hot spots is reduced, and the devices in the closed-door cabinet can work more efficiently.
Description
Technical field
The utility model relates to machine room field of radiating, and especially, relates to a kind of cooling device for closing door rack.
Background technology
Along with the raising of the integrated degree of server, the power of data center's single chassis significantly promotes.According to statistics, now up-to-date blade server frame power is up to 15KW, and desk-top server rack power is 1.5KW, and modular server rack power is 5KW.
High power consumption certainly leads to high heating, and this becomes terribly local pyrexia, and thermograde changes greatly, and aeration-cooling processing is complicated.The shutdown of air-conditioning short time or refrigerating capacity deficiency, computer room temperature can raise rapidly, causes the delay example of machine of server also not rarely seen because temperature rise in server is too high.
There is mechanism to do statistics to the delay reason of machine of data central machine room server, find that two other topmost reason is respectively environment temperature too high (accounting for 32%) and power-off (accounting for 22%) except server itself breaks down and causes.Excess Temperature in settlement server rack, is the problem that current data center machine room generally faces as can be seen here.
Currently come, the design of air-conditioning system refrigerating capacity or air output is too small, machine room overall situation air current composition is unreasonable, interior of equipment cabinet subenvironment air current composition is unreasonable, rack thermal value is excessive, to arrange the problem such as too intensive be the main cause that causes local overheating to rack, address these problems, should set about being analyzed from the planning and design of machine room, refrigerant system design and three aspects such as lectotype selection, applicating maintenance, and provide the solution of highly dense system.
At present, using the air-conditioning system of lower air-supply is the selection of main flow electronic information system machine rooms.The Cryogenic air that the air current composition of lower air-supply can blow out machine room Special precision air-conditioning is directly delivered in electronic message unit by underfloor air supply plenum chamber, Cryogenic air absorbs after the heat of electronic message unit, and machine room Special precision air-conditioning top is got back to by slave roof portion.Use this air supply mode, air-conditioner wind flow direction is consistent with air characteristics, the air-conditioning effect easily obtaining.
Be covered with the data center module of raised floor, the passage that the cold air of air-conditioning often sees through under floor is sent to each rack.But when cold air is communicated to long-range rack, air quantity weakens, add and under raised floor, be conventionally also covered with cable and pipeline, more the transmission of cold air has been increased to obstruction, caused the significant problem of focus (Hot Spot), this situation is referred to as again hot localised points.
But, not should be certain hot localised points and reduce the design temperature of air conditioner in machine room.Because the design temperature that reduces air conditioner in machine room can not thoroughly solve the problem of hot localised points, will significantly increase again machine room entirety energy consumption.
Solving the common way of hot localised points is the refrigerating capacity that strengthens whole machine room, and this method not only energy consumption strengthens, and hot localised points still happens occasionally, and cannot fundamentally solve.This is due to refrigerating capacity deficiency in the not machine room of hot localised points appearance, but Cryogenic air is not effectively delivered to hot localised points rack place.In addition, in addition by increasing point-to-point active refrigeration mode, i.e. fitting machine posture accurate air-feeding air-conditioning, but the shortcoming of this mode is to invest greatly, and deployment cycle is long, and installation is implemented more difficult.The cold (cold wind) that initiatively blowing unit (ADU) can be used for air conditioner to produce is dispensed into equipment enclosure place accurately, forcibly.
In existing technology, there is a kind of similarly active blasting floor, but can only be used for mesh door rack, as shown in Figure 1, for the vertical view of active blasting floor and mesh door cabinet combination in prior art, in the machine room of the air current composition of blowing under employing floor, the cold wind that precise machine room air conditioner blows out is sent in underfloor bellows, the blasting floor of hollow out is all installed before mesh door rack, and the cold wind under floor in bellows sucks by the serviced device of blasting floor.But this structure can not be applied to closing door rack.
Easily form hot localised points for closing door rack in correlation technique and cause the low problem of even damaging of device work efficiency in rack, not yet propose at present effective solution.
