Description
The utility model relates to a kind of standby sink, particularly relates to the standby sink of a kind of tandem fan.
Usually have several standby fan monomers with situation in the existing radiation system in response to fault.Yet several fan monomers in the existing radiation system be independent the existence or setting in parallel mostly, and promptly these fan monomers all have separately fan frame and independently wind inlet and exhaust outlet.So, when a certain fan monomer fault, come loss though can improve the rotating speed mode of other fan monomer in response to this heat dissipation potential, yet, inevitably, the fan monomer of this fault still can cause gas leakage and tie down whole heat dissipation potential in whole system.
In addition, though there has been the fan of series connection in the prior art, it is to be used to increase air quantity.Be that tandem fan of the prior art obviously is not to be as standby sink.
Therefore, need a kind of sink in the prior art, its have standby functions and wherein the fan monomer of fault can not cause gas leakage.
Fan monomer in the existing radiation system perhaps has the relation of mutual interlock on electric, yet must be noted that these fan monomers all have fan frame and independently wind inlet and exhaust outlet separately.Be that these fan monomers do not have actual annexation.So, when a certain fan monomer fault, though other fan monomer can improve rotating speed with the loss in response to this heat dissipation potential,, the fan monomer of this fault still can cause gas leakage and tie down whole heat dissipation potential.
In brief, unlike the prior art be fan monomer arranged in series each other in the standby radiation system of the present utility model.But it should be noted that the utility model be not only be with two separately independently fan (have separately fan frame, independently wind inlet and exhaust outlet) do a simple combination because so essential bindiny mechanism by many complexity, and assembling is difficult for also time-consuming.
The purpose of this utility model is to provide a kind of sink with standby functions, and wherein the fan monomer of fault can not cause gas leakage, and the utility model is reached above-mentioned purpose with the standby sink of a kind of tandem fan.
The purpose of this utility model is achieved in that promptly provides a kind of tandem fan standby sink, comprises following assembly at least: a fan frame; One first fan is coupled in this fan frame; One second fan is coupled in this fan frame, and this second fan and this first fan are for connecting; Wherein, second fan during this first fan failure is high-revolving.
The utility model also provides a kind of tandem fan standby sink, and it comprises following assembly at least: a fan frame; One first axial fan is coupled in this fan frame; One second axial fan is coupled in this fan frame, and this second axial fan and this first axial fan are for connecting; Wherein, second axial fan during this first axial fan fault is high-revolving.
The utility model also provides a kind of tandem fan standby sink, and it comprises following assembly at least: a fan frame, have one first pedestal and one second pedestal, and this second pedestal is coupled in the lower surface of this first pedestal; One first slewing gear is positioned on the upper surface of this first pedestal, and this first slewing gear has one first blade structure; One second slewing gear is positioned on the upper surface on this second pedestal, and this second slewing gear has one second blade structure; Wherein, second slewing gear during the first slewing gear fault can be in response in the signal of this first slewing gear and improve rotating speed.
The advantage of the utility model device is that it is provided with serial fan, makes its heat dissipation potential strong, and simple in structure, easy to assembly.
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail, wherein:
Fig. 1 is fan monomer of the present utility model and arranged in series schematic representation;
Fig. 2 is a Block Diagram of the present utility model.
See also Fig. 1, the standby sink of tandem fan of the present utility model comprises fan frame 300, one first slewing gear 100 and one second slewing gear 200 at least.Wherein this first slewing gear 100 and this second slewing gear 200 can be for flowing brushless motor always, but do not limit.This fan frame 300 also has one first pedestal 310 and one second pedestal 320, and this second pedestal 320 is coupled in the lower surface of this first pedestal 310.This first slewing gear 100 is positioned on the upper surface of this first pedestal 310, and this first slewing gear 100 more is coupled in one first blade structure 110 and constitutes one first fan.This second slewing gear 200 is positioned on the upper surface of this second pedestal 320, and this second slewing gear 200 more is coupled in one second blade structure, 210 formations, one second fan.From the above, because this second pedestal 320 is coupled in the lower surface of this first pedestal 310, so this first fan is the configuration of connecting with this second fan.In this preferred embodiment, this first slewing gear 100 and first blade structure 110 constitute an axial flow fan, and this second slewing gear 200 and second blade structure 210 also constitute an axial flow fan.
See also Fig. 2, this first slewing gear 100 also has a first control circuit 120 and one first signal output part 130 in the utility model, and above-mentioned second slewing gear 200 also has a second control circuit 220 and a secondary signal output terminal 330.Wherein this first signal output part 130 is coupled in this second control circuit 220; This secondary signal output terminal 230 is coupled in this first control circuit 120.Whether normally the signal that this first signal output part 130 and this secondary signal output terminal 330 are exported is expression rotating speed signal.For example work as rotating speed just often, this signal is a logical one, and when rotating speed was unusual, this signal was a logical zero.But work as rotating speed just often, this signal also can be logical zero; When rotating speed was unusual, this signal was a logic " 1 ".
Still see also Fig. 2, when first slewing gear 100 and this second slewing gear 200 all just often, this first slewing gear 100 all can turn round with the slow-speed of revolution with this second slewing gear 200.Yet when a slewing gear fault is wherein arranged, another slewing gear will improve rotating speed.For example, when first slewing gear, 100 faults, this second control circuit can improve the rotating speed of second slewing gear 200 in response to the signal of exporting in first signal output part 130, compensates the heat dissipation potential of being lost with this.
The utility model is stressed that the fan monomer in the existing sink perhaps has the relation of mutual interlock on electric, yet these fan monomers all have fan frame and independently wind inlet and exhaust outlet separately.Be that these fan monomers do not have actual annexation.Fan monomer of the present utility model with regard to mechanical structure, is coupled in the single fan frame except that the relation with electric mutual interlock, and series connection each other, therefore can solve the problems of the prior art (for example gas leakage).Because first slewing gear 100 is arranged in same fan frame with this second slewing gear 200 in the utility model, and series connection each other, therefore when a slewing gear fault wherein, another slewing gear can improve rotating speed immediately, and can not cause the phenomenon of gas leakage at the slewing gear place of fault.
