Description

Four column type fans

Technical field

The utility model relates to a kind of four column type fans, relates in particular to a kind of personal computer that is applied to so that four column type fans of radiating effect to be provided.

Background technique

Fast development along with computer technology, each device in the personal computer, as central processing unit (CPU), display card etc., under the situation that its processing rate, running speed constantly rise, the problem that not only causes those electronic equipment operating temperatures to rise, and power supply unit is in order to provide corresponding electric power, also need expend more high-power, therefore the operating temperature of power supply unit also rises thereupon, therefore, how effectively and apace to reduce the operating temperature of electronic equipment, make the normal operation of electronic equipment energy, become the focus that industry is paid close attention to; In order effectively to reduce the heat of electronic equipment, the general practice is that fan is set in electronic equipment, whereby the hot gas of electronic equipment is extracted out to reach the effect of heat radiation.

Come out about the existing numerous relevant patents of the technology of radiation fan at present, shown in TaiWan, China I323764 patent case, it discloses a kind of fan blade flow guide structure, its blade end in fan is provided with a guide plate, this guide plate forms vertical configuration, makes the air-flow priming of starting fan, can be by the setting of guide plate, and can lead back for centrifugal outside air-flow block, to avoid part air-flow lateral leakage.

In addition, and for example shown in the TaiWan, China I323968 patent case, it discloses a kind of combination of fans structure, it comprises a pedestal at least, one stator, one circuit board and an impeller, this pedestal has a first surface and a pair of second surface that should first surface, this circuit board is arranged at this first surface of this pedestal, this stator is arranged at this second surface of this pedestal, and this circuit board and this stator electrically connect, this impeller has a wheel hub, this hubcap covers this stator, and this circuit board and this stator are arranged at this first surface and this second surface of this pedestal respectively, to increase the circuit layout space of this circuit board.

Above-mentioned patent case all discloses a kind of radiation fan, though reach different effects separately, also have common place, that is exactly the radiation fan that above-mentioned patent case is disclosed, its structure includes a flabellum and a framework, and this framework has four frames with around the zone that flabellum is set; In the at present commercially available radiation fan, except as the disclosed structure with four frames of above-mentioned patent case, also develop the fan that no frame design in addition, shown in TaiWan, China M314373 patent case, it discloses a kind of power supply unit of low noise, comprise that an end face has the housing of a vacancy section, and the position of contiguous vacancy section is provided with guide hole at least one side of this housing; One is located at the power supply supply mechanism in the housing; And a gas guide unit of being located in the housing, and this gas guide unit has a pedestal that is fixedly arranged on the housing, and a pair of flabellum that should vacancy section is set on this pedestal, and the guide hole of the lateral margin corresponding housing of this gas guide unit.Whereby, in the time of can making the power supply unit running, utilize the gas guide unit to cooperate the guide hole of housing, the wind that reaches when reducing the flabellum running is cut noise.

But the fan that M314373 patent case is disclosed is not owing to be provided with frame, what cause its flabellum is the state of hollow out all around, therefore, when the flabellum rotating band is taken offence body when flowing, gas enters the fan except that the below by flabellum, also can from around the position of hollow out pour in fan in the lump, so and gas will concentrate on the position of flabellum simultaneously from all directions, and cause the phenomenon of sinuous flow, flabellum also produces a large amount of wind because of gas flow is chaotic and cuts sound, severe patient more, even the radiating effect of fan is descended.
