Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
Example 1
The motor heat dissipation fan of the embodiment is shown in fig. 1-2, and includes a rotary table 1, an installation cylinder 9 is arranged in the middle of the rotary table 1, the installation cylinder 9 is connected with a rotating shaft of a motor, a plurality of groups of fixed fan blades 2 are arranged on the top end of the rotary table 1, a plurality of groups of movable fan blades 3 are rotatably connected to the bottom of the rotary table 1, a spring 5 is further connected between each group of movable fan blades 3 and the rotary table 1, and the other end of each movable fan blade 3 is folded towards the rotary table 1 through the spring 5.
Wherein, the turntable 1 is densely provided with a plurality of groups of air holes 4. The air holes 4 on the rotary table 1 are convenient for dissipating heat at the center of the motor, and the heat dissipation efficiency is improved.
Wherein, fixed flabellum 2 is the arc, and fixed flabellum 2 is the equal angle evenly distributed about the center pin of carousel 1, and the outside of fixed flabellum 2 all stands out in carousel 1.
Wherein, movable flabellum 3 is the arc, and movable flabellum 3 is the equal angle evenly distributed about the center pin of carousel 1, and movable flabellum 3 rotates the in-process and can expand, and the external diameter when movable flabellum 3 rotates is greater than fixed flabellum 2 pivoted external diameter. When the rotating disc 1 reaches a certain rotating speed, the centrifugal force received by the movable fan blades 3 is greater than the pulling force of the spring 5, the movable fan blades 3 start to be unfolded, and the outer diameter of the completely unfolded movable fan blades 3 is greater than that of the fixed fan blades 2.
Wherein, the bottom of the movable fan blade 3 is provided with a side fin 6. In the rotating process of the movable fan blade 3, the side fin plate is subjected to wind resistance, and the wind resistance and the centrifugal force assist the expansion of the movable fan blade 3 together.
Wherein, the bottom of carousel 1 is fixed with sleeve 7, and the inboard fixedly connected with of sleeve 7 has a set of helical blade 8. During the rotation of the turntable 1, the helical blades 8 form helical suction to accelerate heat dissipation.
According to different motor rotating speed ranges, the spring 5 without pulling force is selected, and the outer diameter of the movable fan blade 3 when the movable fan blade is completely unfolded also needs to be matched with the size of the shell of the motor.
During the use, be connected with the pivot of motor through the installation section of thick bamboo 9 on the fan carousel 1 that dispels the heat, the motor during operation, fixed flabellum 2 follows to rotate together and form the wind channel and dispel the heat.
