Description
Technical field
The utility model relates to the heat dissipation technology of the electronics or the communications field, particularly a kind of fan frame and and combination that is applied to The forced air cooling.
Background technique
In large-scale communication apparatus, heat radiation is important aspect in the system design, and what most integrated chassis equipment adopted is the technology of forced air cooling.As shown in Figure 1, fan frame 1 is arranged on cabinet top, when fan 2 runnings, in board area 5, just in integrated chassis, form a complete air channel, as shown in Figure 2, cold wind enters from intake grill 3, runs through the air channel, takes away the heat of air channel internal heat generation veneer and discharges.
When adopting above-mentioned forced air cooling technology to dispel the heat, the design of fan frame is the key of decision radiating effect quality; Simultaneously, how the fan frame backs up the reliability that also directly has influence on whole system.Present existing fan frame mainly contains following three kinds:
Prior art one:
As Fig. 3, shown in Figure 5: this scheme is used a plurality of axial fans 5.When damaging one or more fan, all the other can work on.
The shortcoming of prior art one:
1, owing to a plurality of fans backups of employing, when wherein one or more damage, must integral replacing fan frame.When changing the fan frame, system only can natural heat dissipation, can not work long hours, and heat can not in time distribute simultaneously, and reliability reduces greatly.
2, owing to adopt axial fan, when system power is very big, must above fan, reserve enough spaces, thereby cause the long-pending increase of fan frame body.
3, owing to mix in the air channel of a plurality of fans, and air-out direction is vertical with fan air blast direction, and the part has hot air flows backwards, and radiating effect is bad.
Prior art two:
As Fig. 2, shown in Figure 6: this scheme resolves into two or more small fan frames 1 with a whole fan frame on the basis of such scheme.Last figure be about two small fan frames 1, two fans 2 are arranged in each fan frame 1.Still use a plurality of axial fans 2.When damaging one or more fan 2, all the other can work on.
In this scheme, any one fan damages, and can independently change the framework 1 at bad fan place, and all the other can work on, and does not need to shut down.
The shortcoming of prior art two:
1. owing to adopt axial fan, when system power is very big, must above fan, reserve enough spaces, cause the long-pending increase of fan frame body.
2. because mix in the air channel of a plurality of fans, and air-out direction is vertical with fan air blast direction, and the part has the hot air refluence, radiating effect is bad.
Prior art three:
As Fig. 4, shown in Figure 7: this scheme isolates a plurality of air channels in a fan frame 1, use a plurality of centrifugal cutters 2 respectively, and each fan 2 has the independent ventiduct of oneself.When damaging one or more fan 2, all the other can work on.
The shortcoming of prior art three:
1, owing to a plurality of fans backups of employing, when wherein one or more damage, must integral replacing fan frame.When changing the fan frame, system only can natural heat dissipation, can not work long hours, and heat can not in time distribute simultaneously, and reliability reduces greatly.
2, in fan frame center, air-flow is freely not suitable, and radiating effect is not best.
In sum, mainly there is following problem in prior art:
1, whether the fan frame can back up and independent the replacing.
2, whether each fan is assigned independent ventiduct, thereby increases radiating effect to greatest extent.
Summary of the invention
The utility model provides a kind of fan frame and combination thereof, so that air channel in the fan frame that solves prior art is not only upright and the fan frame can not back up and the independent deficiency of changing.
A kind of fan frame comprises framework, is separated out at least two independent ventiducts by spacer element in the described framework, and the air-out direction in described air channel is parallel.
A kind of combination fan frame is made up of at least two independent frameworks, is separated out at least two independent ventiducts by spacer element in the described independent framework.
Be separately installed with fan in the described air channel.
Described fan is a centrifugal cutter, and parallel staggered floor with the framework bottom surface is arranged.
Described fan is an axial fan, favours framework bottom surface staggered floor and arranges or arrange at interval in the framework bottom surface.

Embodiment
Embodiment one:
As shown in Figure 8, be the design of single fan frame 1.Structural member 6 forms T shape structure, and framework 1 is divided into two sheaf spaces (structural member is not limited to and must vertically installs) up and down, and the framework lower layer space is separated once more.Fan divides the upper and lower layers arranged in dislocation in frame, and the air channel of each fan 2 isolates by structural member, and mutual noninterference during fan running, is drawn into hot air from intake grill, sends through independent ventiduct and exhaust outlet.Fan adopts centrifugal cutter, and air flow as shown in Figure 9.This scheme can adopt the stepped successively installation of plural fan, and each fan all has independently air channel, satisfies the demand of high-power system.
As shown in figure 12, during actual the use, an above fan frame 1 is used in combination, each fan frame can independently be born the heat radiation of system, also can independently change, to reach better radiating effect.
This scheme optimization design is:
1, the heat radiation of system is distributed to two groups of fan frames arranged side by side, backuped each other, the heat radiation that every group of fan frame can the independent support system.When one of them fan damages, can not shut down and change the fan frame.
2, adopt centrifugal cutter in single fan frame, for powerful equipment, radiating effect is better.And compare with axial fan, needn't above fan, reserve the space of air flow divert, can reduce volume.
3. in the single fan frame, each fan has oneself independently air channel, and the air channel can not mixed.Do not have local hot air and flow backwards, radiating effect is better.
Embodiment two:
As shown in figure 10, this scheme adopts axial fan, and is fan is 2 parallel, be installed on framework 1 bottom surface at interval.The structural member 6 that two vertical (also can out of plumb setting) be provided with will be separated out two or more nested separate space in the framework, fan 2 is installed in respectively in each separate space, be separated out independently air channel by structural member 6, during fan running, be drawn into hot air from intake grill, send through independent ventiduct and exhaust outlet.
As shown in figure 12, during actual the use, an above fan frame 1 is used in combination, each fan frame can independently be born the heat radiation of system, also can independently change, to reach better radiating effect.
Embodiment three:
As shown in figure 11, this scheme is with different pointing out with embodiment, and fan 2 adopts axial fans, is the rule that flows to of the air that meets the axial fan running, with the installation of tilting of the fan except that bottom, makes the unobstructed air channel of its formation.This scheme can adopt the stepped successively installation of plural fan equally, and each fan all isolates independently air channel by structural member 6, satisfies the demand of high-power system.
As shown in figure 12, during actual the use, an above fan frame 1 is used in combination, each fan frame can independently be born the heat radiation of system, also can independently change, and adopts technical solution of the present invention can receive following beneficial effect to reach better heat radiation effect:
1, the reliability of system is higher. Two groups of fan frames back up mutually, and every group of fan frame can be for a long time only The heat radiation of vertical support system. When one of them fan damages, can not shut down to change fan frame.
2, radiating effect is better. When adopting centrifugal fan, needn't rely on framework to come forced draft to turn to. And each fan has oneself independently air channel, and the air channel can not mixed. Do not have local hot-air and flow backwards, Radiating effect is better.
