Abstract

The utility model discloses a heat radiating fan flabellum structure for motors. The surface of one side of the fan flabellum body is provided with a plurality of vertically standing flabellums. The fan flabellum body is encircled by the flabellums in spaced shapes among the flabellums. The center of the fan flabellum body is provided with a shaft ring outward connected with the disc surface of the fan flabellum. The flabellums form a 90 degrees vertical angle with the disc surface of the fan flabellum, so that wind resistance is relatively small and relatively strong wind volume can be generated. The shaft ring is sheathed on the periphery of the head end of the shaft center of the motor. A screw passes through a shim and the shaft ring and is locked on the circle center of the head end of the shaft center of the motor, so as to form a high speed flow guiding wind inducing force. The disc surface of the fan flabellum inclines an angle sideward and downward to serve as the function of guiding, so as to make wind passes through the flabellums and flows out along the slope of the disc surface of the fan flabellum.

Description

Motor heat radiation fan blade structure

Technical field

The utility model relates to a kind of motor heat radiation fan blade structure.

Background technology

No matter traditional type motor flabellum 1,2 is just to change or reverse (Figure 1 and Figure 2), all can influence air quantity, limited flabellum and arc shaped blade structural limitations only can one turn to blowing, if oppositely reverse then is obstructed and can't be used, basically the motor flabellum rotates and promptly can produce noise problem, level of noise can be up to 40d B, main cause is the flabellum and air outlet very so-called near producing (wind the is cut sound) friction of fan itself, and most of flabellum fixed form is to lock in the shortcoming that the axle center of motor side easily causes windage and sinuous flow with screw.

Summary of the invention

The purpose of this utility model provides a kind of motor heat radiation fan blade structure that windage produces big air quantity that reduces.

Above-mentioned purpose of the present utility model is to realize like this, a kind of motor heat radiation fan blade structure, it is characterized in that: this flabellum body one side surface is provided with the plural blade that stands vertically, be a trellis between this blade around this flabellum body, these flabellum body central authorities are provided with the axle collar and outwards are connected with the flabellum card, this blade is vertical 90 degree angles with the flabellum card, blade tip level of incline face one angle, and become a circular arc in the rear end, the aforementioned axis ring set is located at axle center of motor head end periphery, screw passes the locking of pad and the axle collar in the axle center of motor head end center of circle, this flabellum card to side direction declivity one angle as guiding function.

Wherein, this flabellum body extended blade is for erectting arc angle.

Wherein, this flabellum body is fixed with screw, and screw locks in axle center of motor central authorities and is a straight line.

The utility model is elaborated with instantiation below in conjunction with accompanying drawing.

Embodiment

As Fig. 3, Fig. 3-1, Fig. 3-2 and shown in Figure 4, the utility model provides a kind of motor heat radiation fan blade structure, these flabellum body 3 one side surfaces are provided with the plural blade 4 that stands vertically, be a trellis between this blade 4 around this flabellum body 3, and blade 4 tops 41 level of incline faces, one angle, and become a circular arc 42 to guide backward in the rear end in order to wind direction, the axle collar 5 that these flabellum body 3 central authorities are provided with outwards is connected with flabellum card 6, this blade 4 is vertical 90 degree angles with flabellum card 6, just make, counter-rotating all has identical blast, the aforementioned axle collar 5 becomes two planes 50 by preceding end mill, axle center of motor 7 head end peripheries are located at for circle shape 52 engage sleeves in 51 rear ends, with screw 8 pass 5 lockings of pad 9 and the axle collar in the axle center of motor 7 head end centers of circle to avoid skid, form a high speed water conservancy diversion air inducing strength, this flabellum card 6 according to level to declivity one angle as guiding function, wind is flowed out through this blade 4 along the inclined-plane 61 of flabellum card 6.

See also Fig. 5, the utility model provides a kind of motor heat radiation fan blade structure, this flabellum card 6 is to side direction declivity one angle, be subjected to the guiding on this inclined-plane 61, when this flabellum body 3 is just changeing or is oppositely reversing, all folk prescription is to casting aside backward via the axle collar 5 central authorities for wind, and wind is stopped promptly produce preferable identical blast energy.

Below the utility model and conventional art are compared:

Conventional art

1, forward or counter-rotating the time can't make the unidirectional output of wind.

2, produce so-called (wind is cut sound) friction and cause noise problem.

3, limited flabellum and arc shaped blade structural limitations only can one turn to blowing, if the reverse reverse nothing of then being obstructed Method is used.

4, screw locks in the axle center of motor side and easily causes windage and sinuous flow.

The utility model

1, just changeing or all can make the unidirectional output of wind when reversing.

2, can not produce (wind is cut sound).

3, screw will pass the locking of pad and the axle collar in the axle center of motor head end center of circle, no windage problem.

Claims

1, a kind of motor heat radiation fan blade structure, it is characterized in that: this flabellum body one side surface is provided with the plural blade that stands vertically, be a trellis between this blade around this flabellum body, these flabellum body central authorities are provided with the axle collar and outwards are connected with the flabellum card, this blade is vertical 90 degree angles with the flabellum card, blade tip level of incline face one angle, and become a circular arc in the rear end, the aforementioned axis ring set is located at axle center of motor head end periphery, screw passes the locking of pad and the axle collar in the axle center of motor head end center of circle, this flabellum card to side direction declivity one angle as guiding function.

2, motor heat radiation fan blade structure as claimed in claim 1, wherein this flabellum body extended blade is for erectting arc angle.
