Description

The low clearance heat abstractor

The utility model relates to a kind of low clearance heat abstractor.

The known heat abstractor that is applied to industrial computer 3, extremely shown in Figure 8 as Fig. 6, this heat abstractor 3 mainly comprises tubeaxial fan 30 and heat radiator 40, wherein: tubeaxial fan 30, possess shell 37 and this shell 37 peripheries and be provided with some protuberances 34 with perforation 35, above-mentioned shell 37 is also carrying the motor 36 that is provided with some blades 33, and described tubeaxial fan 30 has homoaxial air intake vent 31 and air outlet 32; Heat radiator 40 has pedestal 41 and reaches from the upwardly extending majority of pedestal 41 1 sides radiating fin 42 arranged side by side, 42 formation ventilation slots 44 of per two fins of being separated by, what also have laterally is provided with fluting 43 (as the zones of Fig. 8 dotted line) in the position of central authorities approximately at above-mentioned fin 42, makes each fin 42 in fluting 43 interruptions, discontinuous.

Above-mentioned tubeaxial fan 30 passes perforation 35 through some screws (figure does not show) and is locked on the fin 42 of above-mentioned heat radiator 40, and pedestal 41 belows of heat radiator 40 are then by pasting the wafer (figure does not show) that will dispel the heat.When fan 30 energisings drive running, air-flow is blowed to heat radiator 40 (seeing Fig. 6 arrow) and is discharged (seeing Fig. 8 arrow) by ventilation slot 44 by air outlet 32 again by the air intake vent 31 that the top enters fan 30, by cross-ventilation, reach the purpose that the fin 42 that will absorb the wafer thermal source is dispelled the heat.Because of inlet air, the air-out of tubeaxial fan 30 is to be on the same axis, thereby must there be suitable space fan 30 tops as the air inlet height, this air inlet (is D/4 for 1/4th of fan 30 transverse width D highly, as be lower than this number and will influence fan air inlet benefit), thereby the height of heat abstractor 3 configured in one piece in industrial computer is the overall height H (see figure 6) that air inlet height (D/4) adds fan 30 height and heat radiator 40 height.If be used in the industrial computer height when being 1U (1U=4.44mm), under the pressure of must retaining the height that air inlet highly has to reduce fan 30 or heat radiator 40, promptly reduced the radiating effect of wafer since like this; Moreover the wind-force of fan 30 is to blow from top to bottom to pedestal 41, and axial wind-force can rebound and cause the high resistant flow phenomenon, can't obtain the radiating effect that excellent cross-ventilation produces; Offer transversal slotting 43 for reaching the cross-ventilation effect, but reduced the cooling surface area of fin 42, also reduced radiating effect.

At the shortcoming that prior art exists, the purpose of this utility model is to provide a kind of low clearance heat abstractor, effectively reduces the assembled height of industrial computer, can effectively reach the effect of the heat radiation of the wafer in the computer simultaneously.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of low clearance heat abstractor, it is characterized in that: it comprises turbine fan and has the heat radiator of the fin of vertical and landscape configuration, above-mentioned turbine fan is installed on the heat radiator, between vertical, the horizontal fin of heat radiator ventilation slot is arranged, the turbine fan below is provided with air intake vent, is provided with air outlet in the turbine fan side.

Vertically fin or horizontal fin are provided with the projection that at least one increases cooling surface area.

By a kind of low clearance heat abstractor of the utility model, overcome the shortcoming that prior art exists, reached the purpose of above-mentioned creation; Because the heat abstractor overall height that turbine fan and heat radiator assembling back are constituted only is the height of heat abstractor, need not extra air inlet height, and is specially adapted to industrial computer (PC also can be used); Moreover the cross-ventilation mode of the utility model low clearance heat abstractor can not cause wind-force bounce-back, thereby cross-ventilation is excellent and have an excellent radiating effect; The loose heat radiator of low clearance heat abstractor of the utility model, its fin is vertically, landscape configuration, effectively increases area of dissipation and reaches superior radiating effect; Its fin also can add projection to increase surface area, can increase by 30 percent radiating effect again.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
