Referring to accompanying drawing 1 and Fig. 2, on the front panel 10 of the cabinet casing 16 of 2U cabinet and rear panel 11, be covered with air vent, cabinet is divided into former and later two casings by dividing plate 19, and aerofoil fan group 6 is installed on this dividing plate.In the installation site of aerofoil fan, dividing plate has corresponding air vent by the air communication mistake.Air channel dividing plate 12 is divided into 14 two air channels in left air channel 15 and right air channel to preceding casing.Power supply 8 is installed in the left air channel of preceding casing, equipment such as CD-ROM drive, hard disk 17 are installed in the right air channel.
Mainboard 13 and PCI slot 9 are installed in the rear box.Wind scooper 5 flares are made by insulating material.The hydraucone of wind scooper is inlet, and a plurality of aerofoil fans are installed in its porch.Wind scooper can continue right air channel with the guide duct that mainboard 13 forms, and the heating radiator 1 that is installed on the processor 20 is positioned at wherein, and the fin of heating radiator is parallel with the airflow direction 14 that aerofoil fan promotes.Four heating radiator parallelograms are arranged, and are little than the heat sink size of the other end near the heat sink size of fan one end.See and to find to the direction of heating radiator from aerofoil fan, be covered with the fin of heating radiator on the surface level in the whole wind scooper.
Part beyond the rear box wind scooper is left air channel, and at least one aerofoil fan is installed on the box partition.The air-flow 15 in air channel, a left side is discharged cabinet through board chip set 18 and PCI slot 9.
24 dotted lines that mark are wind scooper 25 projections on mainboard 13, it is the rigging position of wind scooper 25, the heating radiator 1 of four processors all is positioned at wind scooper 25, the height of wind scooper 25 is a little more than heating radiator 1, one end of wind scooper 25 is fixed by snap on dividing plate 19, the other end is fixed on the rear panel 11, leaves a small amount of space between wind scooper 25 and the mainboard 13; 32 and 33 are respectively the cover plate of former and later two casings of cabinet.
Accompanying drawing 2 is the perspective view of 2U case radiation system, has clearly showed the position relation between each parts.
The present invention is the solution of an overall thinking.At first the layout of equipment has been carried out unified planning to prevent concentrating of heat generating spot in the cabinet, isolate two wind paths by wind scooper and air channel dividing plate then, separate different heat-producing devices, promote cross-ventilation inside and outside the cabinet by the one group of aerofoil fan that is placed on cabinet middle part again, thereby reach best radiating effect.
The inside of cabinet is divided into former and later two casings among the present invention, and preceding casing is used for equipment such as discharge source, hard disk, CD-ROM drive; Rear box is used for placing the PCI slot (PCI---Peripheral ComponentInterconnection, peripheral parts interconnected) of server master board and interpolation.Cooling system is made up of dividing plate, aerofoil fan group, heating radiator, wind scooper, air channel dividing plate, cabinet casing.Wherein the front panel of cabinet casing and rear panel all have enough air vents.Two air channels about air channel dividing plate and wind scooper are divided into cabinet: left air channel is mainly passed through Switching Power Supply, board chip set and is added pci card; The heating radiator of hard disk, CD-ROM drive and processor is mainly passed through in right air channel.
The benefit of separating the air channel design is:
1, disperses heat-producing device, avoid focus to concentrate.In cabinet, the equipment of thermal value maximum is processor, secondly is Switching Power Supply, they is placed on different air channels can avoids Switching Power Supply heat radiation heat radiation causes harmful effect to processor.
2, formed a guide duct of sealing relatively between wind scooper and the mainboard, the high blast that the aerofoil fan group produces can be kept in wind scooper preferably, is suitable for the heat of processor is directly discharged cabinet, reduces the accumulation of heat in cabinet.
3, the high temperature of isolation processing device generation.Processor is the equipment that heating is serious, and it also can be operated under the higher temperature simultaneously, and much other equipment is comparatively responsive to temperature, and as clock circuit, temperature variation causes frequency drift easily.If there is not the air channel that isolates, the heat that processor produces can cause that temperature in chassis is whole to raise, though processor can be under this temperature operate as normal, it is undesired that miscellaneous equipment also may be worked.The air channel has produced two different warm areas after separating, and has reduced the influence of the heat of processor generation to miscellaneous equipment.
In the entire heat dissipation system, the heat radiation of processor is the most important thing.Because four processors that concern in space can not be arranged in a line, when putting, the temperature that is placed on the wind that the processor near fan one end obtains is lower, blast is also bigger, and can be subjected to certain influence at the radiating effect of the processor of back.The present invention has used two methods to reduce this influence:
1, the heating radiator of four processors adopts the parallelogram layout, and wind can blow to the rear end heating radiator by the space on front end heating radiator next door, thereby the rear end heating radiator also can obtain the cold wind that blows from fan.
2, the processor that is placed on the rear end uses the bigger heating radiator of size, remedies the negative effect that blast and the temperature difference reduce to bring by bigger area of dissipation, thereby makes the processor that is positioned at the rear end obtain the radiating effect the same with the processor that is positioned at front end.
The fan that the heating radiator of processor does not carry, but promote flowing of air by one group of aerofoil fan.Such design has an extra benefit, when a fan damages, though the wind speed that the fan group produces can reduce, the temperature of processor can sharply not rise to the degree that can not work or damage, has so just improved the reliability of cooling system to a certain extent yet.
Cooling system of the present invention is mainly used in four road servers of 2U.Certainly the cooling system that is applicable to the 2U cabinet can be used for the above cabinet of 2U equally, but in bigger cabinet, conventional art also can meet the demands.For the 1U cabinet, if increase the area of heating radiator and the power consumption of processor is limited, the present invention can be suitable for equally, no matter is to use the cabinet of several U, way of realization of the present invention is consistent, the just corresponding height that changes wind scooper and processor heat radiator.
Unique requirement that wind scooper is installed is the heat radiator that can comprise processor, and the position of heat radiator is by the layout decision of processor on mainboard.The ATX standard is all followed in the design of present most of mainboard; ATX standard-required pci expansion slot is arranged in the left side of mainboard; when PCI Mezzanine Card is installed not with the clashing of processor heat radiator, processor is disposed in opposite side usually, that is to say that wind scooper can be placed on the right side of cabinet usually.
It should be noted last that: above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the present invention, and not breaking away from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.Can resolve into a plurality ofly as wind scooper, for example be divided into two, each comprises two heating radiators, and the shape of wind scooper can change in addition.
Wind scooper also can resolve into a plurality of, when for example being divided into two, comprises two processor heat sinks in each wind scooper; Its embodiment can be original wind scooper is divided into from the centre about two, nestle up put together after, monnolithic case remains unchanged (as add a vertical dividing plate in the middle of former wind scooper, it being divided into left and right sides two halves).Two heat radiator in the wind scooper also are staggeredly placed, and the heating radiator of putting behind has bigger area of dissipation.
