Description
Technical field
Relevant a kind of radiating subassembly of the present invention and flow direction control structure thereof, and particularly relevant a kind of radiating subassembly that has may command or obstruct air-flow adverse current and keep the identical flow direction control structure of whole air-out area.
Background technology
Continuous lifting along with electronic installation usefulness, heat abstractor has become one of outfit indispensable in the existing electronic installation, because the heat energy that electronic installation produced if can not be in real time suitably in addition dissipation, gently then cause electronic installation usefulness variation, heavy then can cause burning of electronic installation.And heat abstractor is for micromodule (integrated circuit for example, integrated circuits) important especially, because along with the increase of integration and the progress of encapsulation technology, make the area of integrated circuit constantly dwindle, simultaneously the heat energy accumulated of per unit area also relatively can be higher, so the heat abstractor of high heat dissipation efficiency is the positive object of researching and developing of electronic industry circle institute always.
Therefore, be generally the problems such as exhaust, convection current or heat radiation of heat-generating systems such as solution such as server, computer, electricapparatus, power supply unit, often use as radiator fan or other tool same functional devices such as axial flow fan, centrifugal fans, flow in specific passage with steering current, the high heat that is produced so that electronic installation is operated brings to the external world, to use as heat radiation or air-conditioning convection current.
Please refer to Figure 1A, it is the schematic diagram of existing parallel fan.Existing parallel fan 10, at least comprise first heat abstractor 110 and second heat abstractor 120, and first heat abstractor 110 and second heat abstractor 120 are two aerofoil fans or blower fan, discharge from air outlet 111 and air outlet 121 respectively in order to the fluid that will enter first heat abstractor 110 and second heat abstractor, 120 inside respectively.
When first heat abstractor 110 and second heat abstractor 120 all run well, first heat abstractor 110 and second heat abstractor 120 can make the fluid that enters first heat abstractor 110 and second heat abstractor, 120 inside discharge toward air outlet 111 and air outlet 121 respectively, yet, when one of them fan, for example be that second heat abstractor 120 is malfunctioning or when breaking down, only remaining first heat abstractor 110 can run well, make the fluid that enters first heat abstractor, 110 inside still discharge from air outlet 111, but because of the air outlet 121 of second heat abstractor 120 directly is communicated with extraneous, cause fluid can free in and out in air outlet 121, thereby may cause the phenomenon of extraneous fluid countercurrent current, cause second heat abstractor, 120 accumulated inside heat radiation fluid, have influence on the normal operation of first heat abstractor 110 even, and then reduce its radiating efficiency.
In order to stop extraneous fluid countercurrent current, the existing practice is the compensation mechanism of setting up the power of the heat abstractor of heightening normal operation.This kind compensation mechanism is malfunctioning or when breaking down when the part fan, the power of the fan that still can run well is heightened, make the fan of its normal operation compensate the heat radiation power that fan malfunctioning or that break down is missed, make the forced convertion (forcedconvection) that to carry out fluid in second heat abstractor, 120 inside, and reach the purpose that the fluid of first heat abstractor 110 and second heat abstractor, 120 inside is discharged.Yet, this kind compensation mechanism not only increases manufacturing cost, improves outside the complexity of structure, because it is malfunctioning or break down to and make till the compensation control that self compensation mechanism detects wherein a fan, still needs one period reaction time, and can't do immediately suitably and timely to adjust.Simultaneously, because the air outlet 121 of fan is directly to be communicated with the external world, and can't stop gas backstreaming to fan inside.
Therefore, it is to set up a plurality of spoilers (flapper) at the air outlet place that existing another kind stops the practice of extraneous fluid countercurrent current, please refer to Figure 1B, Fig. 1 C and Fig. 1 D.Figure 1B is the parallel fan of existing tool spoiler, schematic diagram when its fan does not turn round, Fig. 1 C are the parallel fans of existing tool spoiler, schematic diagram when its fan all turns round, and Fig. 1 D is the parallel fan of existing tool spoiler, the schematic diagram when the one fan breaks down.First heat abstractor 110 in the parallel fan 10 and second heat abstractor 120 are set up spoiler 112 and spoiler 122 respectively at air outlet 111 and air outlet 121 places.When first heat abstractor 110 and the 120 neither runnings of second heat abstractor, spoiler 112 and spoiler 122 are because of the effect that is subjected to gravity or by other particular design (a for example biasing device), become closure state, and respectively with air outlet 111 and air outlet 121 sealings, as shown in Figure 1B.
When first heat abstractor 110 and second heat abstractor 120 all turn round, can guide the fluid of first heat abstractor 110 and second heat abstractor, 120 inside to discharge toward air outlet 111 and air outlet 121 respectively, make spoiler 112 and spoiler 122 be subjected to fluid behind the extraneous mobile outward thrust that is produced, the state that becomes to open is as shown in Fig. 1 C.
When one of them fan, for example be that second heat abstractor 120 is malfunctioning or when breaking down, only remaining first heat abstractor 110 can run well, as shown in Fig. 1 D, make spoiler 112 still be subjected to fluid and move the outward thrust that is produced toward air outlet 111, form the state of unlatching, but this moment, spoiler 122 did not move the outward thrust that is produced outward because of there being second heat abstractor, 120 its internal flows of guiding, form closure state, air outlet 121 sealings with second heat abstractor 120, make second heat abstractor, 120 inside that extraneous fluid can't be by air outlet 121 adverse currents to malfunctioning or fault, avoid its accumulated inside heat radiation fluid and have influence on the normal operation of first heat abstractor 110.
Yet, because the design of spoiler is to be configured at individual other fan.When a certain fan in the radiating subassembly operates when bad, spoiler is just with its air outlet sealing, to stop fluid countercurrent current.Thus, correspond to the pyrotoxin place that is closed air outlet, will cause the heat at this pyrotoxin place effectively to disperse, seriously have influence on the stability of whole electronic installation running because of there not being the thermolysis of fan.Simultaneously, the whole air outlet area of radiating subassembly is influenced by this also and significantly reduces, fan component with Fig. 1 D is an example, former whole air outlet area comprises air outlet 111 and air outlet 121, behind spoiler 122 sealing air outlets 121, whole air outlet area just hurriedly subtracts half, seriously causes the radiating efficiency of system unclear.
