Abstract
The utility model relates to a small sized supercharged axial flow fan, belonging to the technical field of small sized axial flow fan, which comprises a fan drum, a frame, a motor, and a plurality of rotating blades. The utility model aims at providing an axial flow fan with more compact size and stronger air draft used in an instrument, a device and a vehicle-mounted radar which need forced heat dissipation and ventilation. The utility model is characterized in that: the frame is positioned at the air inlet of the fan drum; the motor is connected on the frame; the rotating blades are arranged on the rotor of the motor, and a plurality of stationary blades are also arranged on the frame. The utility model has the advantages of formation of eddy flow in the fan drum when the motor driving the rotating blades, air entry of the fan drum through the stationary blades under the force of negative pressure, air pressure increase after continuous cutting and centrifugal compression, obvious improvement of the air volume and air speed, low power consumption, well application for all instruments, electromechanical equipments and vehicle-mounted radars, and enhancement of forced heat dissipation and ventilation effect.
Description
Technical field
The utility model relates to a kind of axial-flow blower, particularly a kind of small-sized supercharging type axial-flow blower.
Technical background
At present, common heat radiation or ventilation have 125FZY type, 145FZY type, 150FZY type, 200FZY type, 300FZY type etc. several with small-sized axial flow fan, these product air quantity are general, consume energy more, wind speed is lower, can not satisfy the needs of forced heat radiation or forced ventilation.
Technology contents
The purpose of this utility model is: the axial-flow blower that volume is less, wind-force is bigger that uses on a kind of various instruments that need forced heat radiation or forced ventilation, electromechanical equipment, the trailer-mounted radar is provided.
The utility model is achieved in that a kind of small-sized supercharging type axial-flow blower, comprise air duct, support, motor, rotor blade, support is positioned at the air duct intake grill, motor is connected on the support, rotor blade is arranged on the motor rotor, it is characterized in that: also be provided with static blade on the support, rotor blade and static blade all are arranged in the air duct.
Described rotor blade and static blade are the center of circle with the motor reel all, and it is evenly distributed to be circumference, and the plane that rotor blade and static blade are formed separately is parallel to each other.
Angle is greater than angle between the blade of static blade between the blade of described rotor blade.
Described rotor blade is a twisted shape, and static blade is crooked shape.
Described rotor blade is eight, and angle is 45 degree between blade; Static blade is nine, and angle is 40 degree between blade.
The utility model is owing to adopt the structural type that has static blade, when the motor drives rotor blade rotates, form eddy current between air duct, air enters air duct through static blade under the effect of negative pressure, and through constantly cutting and throw the process of pressure, blast increases, air quantity and wind speed are significantly improved, the power that consumes also can reduce, and can satisfy the demand of various instruments, electromechanical equipment, trailer-mounted radar well, has strengthened the effect of forced heat radiation and forced ventilation.

Embodiment
As shown in Figure 1, rotor blade 2 is arranged on the external rotor of motor 4, also is provided with static blade 3 on the support, and rotor blade and static blade all are arranged in the air duct 1.Rotor blade 2 is the center of circle with the motor reel all with static blade 3, and it is evenly distributed to be circumference.5 for installing attachment hole among the figure.
As can be seen from Figure 2, support 4c is positioned at the intake grill of air duct 1, and static blade 3 is arranged on the motor bed-plate 4c, and 4b is a motor stator among the figure, and rotor blade 2 is arranged on the motor external rotor 4a.Rotor blade 2 is parallel to each other with the plane that static blade 3 is formed separately.
As shown in Figure 3 and Figure 4, rotor blade 2 is a twisted shape, and rotor blade is eight, and angle is 45 degree between blade.
From Fig. 5 and Fig. 6 as can be seen, static blade 3 is crooked shape, and static blade is nine, and angle is 40 degree between blade.7 is motor power line among the figure.Certainly on the support radiation hole can also be set, be beneficial to the motor heat radiation.
During the actual use of the utility model, the external rotor of motor drives rotor blade and rotates, static blade on the support makes the air between air duct form eddy current effectively, under the effect of negative pressure, more a large amount of air enters air duct through static blade, and through constantly cutting and throw the process of pressure, blast increases, air quantity and wind speed are significantly improved, and the power of consumption also decreases.
