Abstract
The utility model discloses a mixed flow fan, which comprises a shell, a fan housing, a motor and a wind wheel, wherein the fan housing is covered above the shell; the wind wheel and the motor are arranged in the shell; and the wind wheel is connected with an output shaft of the motor. A centrifugal blade is arranged on an end face of the wind wheel corresponding to a wind inlet; and an axial flow blade is arranged on an end face of the wind wheel corresponding to a wind outlet. The mixed flow fan is simple in structure. The centrifugal blade on the wind wheel compresses the inhaled air flow into the inner wall of the shell and the fan housing; the inner end face of the fan housing effectively guide the flow of the gas; and the axial flow blade pushes off the air flow axially to form the air flow with strong concentration and large wind pressure. The mixed flow fan can be applied to electronic components, with a better radiation effect.
Description
Technical field
The utility model relates to the heat-radiating device of electric component technical field, is specifically related to the blower fan that uses for to high-power electronic component heat radiation processes such as transistor, diode, switching tubes.
Background technique
At present, the axial fans that use in the cooling electronic component process more, axial fan is simple in structure, and cost is lower, but air quantity and blast are less, and when the larger cooling electronic component of heating value was used, radiating effect was relatively poor.Centrifugal fan, air quantity and blast are all larger, but cost is higher, has increased the manufacture cost of enterprise.Flow-mixing blower fan is a kind of novel fan between axial fan and centrifugal fan, and therefore, inventor's anticipation designs flow-mixing blower fan, so that it is applicable to the heat radiation of electronic parts and components.
The model utility content
The purpose of this utility model is to provide a kind of flow-mixing blower fan, and this flow-mixing blower fan novel structure is simple and practical.
The utility model to achieve these goals, the technical solution of employing is:
A kind of flow-mixing blower fan comprises casing, fan housing, motor, reaches wind wheel, and described fan housing is buckled in the casing top, and described wind wheel and motor are arranged in the casing, and wind wheel is connected with the output shaft of motor; Be provided with centrifugal film on the end face of the corresponding intake grill of described wind wheel, be provided with the axial flow sheet on the end face of the corresponding exhaust outlet of wind wheel.
Preferably, described axial flow sheet is gradually perk shape along the wind wheel sense of rotation.
Preferably, described fan housing closes up from lower to upper gradually.
Preferably, the interior edge face of described fan housing is provided with guide plate.
Preferably, the exhaust outlet of described fan housing is less than the external frame of wind wheel.
The beneficial effects of the utility model:
This kind flow-mixing blower fan, simple in structure, centrifugal film on the wind wheel is pressed into the air-flow that sucks in casing inner wall and the fan housing, the guide plate of fan housing interior edge face carries out effective water conservancy diversion to gas, the axial flow sheet is released air-flow vertically, the formation property gathered is strong, the air-flow that blast is larger, and it is more excellent that this flow-mixing blower fan is applied to the cooling electronic component effect.
Description of drawings
Fig. 1 is the sectional view of flow-mixing blower fan.
Fig. 2 is the structural representation of wind wheel.
Fig. 3 is the structural representation of fan housing.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
In conjunction with Fig. 1 to Fig. 3, a kind of flow-mixing blower fan comprises casing 1, fan housing 2, motor 3, reaches wind wheel 4, and described fan housing 2 is buckled in casing 1 top, and described wind wheel 4 is arranged in the casing 1 with motor 3, and wind wheel 4 is connected with the output shaft of motor 3.Be provided with centrifugal film 5 on the end face of described wind wheel 4 corresponding intake grills, be provided with axial flow sheet 6 on the end face of wind wheel 4 corresponding exhaust outlets, described axial flow sheet 6 is gradually perk shape along wind wheel 4 sense of rotation.Described fan housing 2 closes up from lower to upper gradually, and the interior edge face of fan housing 2 is provided with guide plate 7, and the exhaust outlet of fan housing 2 is less than the external frame of wind wheel 4.
This kind flow-mixing blower fan, simple in structure, centrifugal film on the wind wheel is pressed into the air-flow that sucks in casing inner wall and the fan housing, the guide plate of fan housing interior edge face carries out effective water conservancy diversion to gas, the axial flow sheet is released air-flow vertically, the formation property gathered is strong, the air-flow that blast is larger, and it is more excellent that this flow-mixing blower fan is applied to the cooling electronic component effect.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
