Description
Technical field
The present invention relates to a kind of fan that has central air induction concurrently, fan frame that particularly in general electronic products, dispels the heat and fan wheel structure.
Background technique
Development along with the electronics technology technology, computer is in order to reach the demand of high execution speed now, cause and order about central authorities and handle with high clock running, its central processing unit (CPU) is handled data with ultraspeed, but accompanies and what come is to produce more thermal energy along with the running speed of central processing unit (CPU) promotes.
Be passed to other place for heat energy being discharged, promptly to need to use sink, the heat energy of central processing unit (CPU) to be shed,, even to cause damaging when machine just then central processing unit (CPU) can be overheated and can't operate as not using splendid sink.
And the sink of the most normal use at present is no more than radiation fan, and therefore be that cost is low also accepted by most of manufacturer its maximum benefit, and be devoted to the major project of research and development.
But limited because of the space in the computer main, make to install the position of fan also relative be confined to space in the main frame, it is also just relative important therefore how to promote its radiating effect at the fan of appropriate size.
Known fan as shown in Figures 1 to 4, comprise fan frame 11 and impeller 12, wherein this fan frame 11 is provided with hub seat 111, and be provided with pin-joint part 112 in hub seat 111 centre, and this pin-joint part 112 is made up of bearing 1121 and pivot 1122, and these fan frame 11 tools are established import 113, outlet 114 is flowed for fluid, more sheathed motor stator 13 on hub seat 111; This impeller 12 comprises wheel hub 121 and blade 122, wherein this wheel hub 121 is provided with a receiving portion 1213, and be provided with motor rotor 14 in the inner ring surface 1211 of wheel hub 121, and this blade 122 grows outside outer ring surface 1212 radiation directions of wheel hub 121, receiving portion 1213 with wheel hub 121 is articulated on the pin-joint part 112 of hub seat 111 again, so that motor rotor 14 is aimed at motor stator 13, impeller 12 is arranged in the fan frame 11.
When motor stator 13 energisings,, and enter via outlet 114 outflows by import 113 by blade 122 draw fluid so that the motor rotor 14 excitatory impellers 12 that drive simultaneously are that rotate at the center with pin-joint part 112.
Please consult Fig. 4 again, shown in Figure 5, it will fan frame 11 and impeller 12 is connected to radiator 16 tops, when rotating, impeller 12 drives fluid by import 113 inflows, the radiator 16 that blows to outlet 114 outwards sheds via the air gap 161 of radiator 16 again, but it implements that its problem place is arranged this a kind of known fan, when being flowed out by outlet 114, fluid around fan frame 11, sheds, because of fluid does not flow toward hub seat 111 rears, cause hub seat 111 rears of fan to produce stagnant area 15, make the heat energy of radiator 16 central authorities to discharge, and then reduce whole heat dissipation potential.
In addition, because of the rotation of the bearing 1121 of the effect of fan motor stator 13 and motor rotor 14 and pin-joint part 112 all is the source that produces heat energy, and then influence radiating efficiency and working life, and known fan does not obviously possess the mode that the thermal source of its generation is discharged, and makes radiating effect unclear.
