Description
The utility model is relevant with a kind of high-effect slim cooling device, particularly relevant a kind of embedded centrifugal cooling device.
Generally speaking, cooling device is to place one to need on the surface of device of heat radiation with its heat that is produced of dissipation.
A kind of existing cooling device 10 has an aerofoil fan 50 and a radiator 60 shown in Fig. 1 (a).Wherein, described aerofoil fan 50 is made up of a wheel hub 53 and several flabellums 55.Described aerofoil fan 50 is to be fixed on the upper surface of described radiator 60, and the lower surface of described radiator 60 is attached on the device that needs heat radiation (not shown, for example a central processing unit).And described wheel hub 53 is to be positioned on the middle section of the described device that needs heat radiation, and flabellum 55 is to be positioned on the outer peripheral areas of periphery in surrounding said central zone.The shortcoming of described existing cooling device comprises that at least (1) cooling effect not good (inhomogeneous) (2) flow field (3) volume that has some setbacks is excessive, and its reason is specified in down.
Be the section and the corresponding temperature distribution history thereof of existing cooling device 10 shown in Fig. 1 (b), the peak value of the temperature distribution history of the described device that need dispel the heat mainly is to appear at the described middle section that needs the device of heat radiation, successively decreases gradually towards outer peripheral areas then.Yet, for existing cooling device 10, its cooling effect to middle section but is the poorest, and the cooling effect of outer peripheral areas is better, because described middle section is to be positioned under the described wheel hub 53, and described wheel hub 53 has no to benefit to take away hot gas for cooling blast is set, thus its cooling effect to middle section not good be understandable.
In addition, the fan that is disposed owing to existing cooling device 10 is an aerofoil fan 50, so just be forced to be diverted to the side outflow of radiator 60 behind cooling blast (shown in arrow among the figure) device (for example its upper surface) that the front bump needs to dispel the heat earlier of this aerofoil fan 50 by the outside introducing.Like this, the flow field of described cooling blast has some setbacks very much, and its flow velocity can be hindered and sluggishness.
Still see also Fig. 1 (a), another shortcoming of existing cooling device 10 is that volume is excessive.Because described aerofoil fan 50 is to be fixed on the surface of described radiator 60, so the thickness of existing cooling device 10 is the thickness that adds the above radiator 60 for the thickness of described aerofoil fan 50.
See also Fig. 1 (c), United States Patent (USP) discloses another kind of existing cooling device 20 No. 5661638.Described cooling device 20 has a tube-axial fan 50 and a radiator 60.Described aerofoil fan 50 is made up of a wheel hub 53 and several flabellums 55, and described radiator 60 has several spiral helicine heat conduction fins 65 and is surrounded on described aerofoil fan 50.Described tube-axial fan 50 is to be embedded in the described radiator 60.Yet the shortcoming of described cooling device 20 comprises that also (3) air-tightness is not good except that (1) cooling effect not good (inhomogeneous) (2) and flow field have some setbacks.Wherein, reason that cooling effect not good (inhomogeneous) and flow field have some setbacks and the cooling device 10 shown in above-mentioned Fig. 1 (a) identical caused by tube-axial fan, therefore repeats no more.
Still see also Fig. 1 (c), the not good reason of described cooling device 20 air-tightness is because the cooling blast in the described cooling device 20 promptly is discharged from before the least significant end that does not reach the heat conduction fin, so the exhausted major part of the heat conduction fin of described radiator there is no and is subjected to brushing of cooling blast and performs practically no function.
Another existing cooling device 30 is shown in Fig. 1 (d), and it has a radiator 50 and a centrifugal fan 60.Described centrifugal fan 60 is sides of being attached at described radiator 50 reducing the thickness of described cooling device 30, yet this kind configuration has increased the shared projected area of existing cooling device 30 also.And the distance with centrifugal fan 60 is all different everywhere owing to radiator 50, thus more will be poor more away from the cooling effect of locating of described centrifugal fan 60, and possibly can't be subjected to brushing of cooling blast with the radiator 50 of centrifugal fan 60 farthest.
The purpose of this utility model provides that a kind of volume is little, air-flow is unimpeded thereby has the cooling device of desirable radiating effect.
