Referring to fig. 1, a heat dissipation structure of a motor casing includes: the inner shell 100 is cylindrical, and the outer side wall of the inner shell is provided with wave-shaped raised stripes 200; the inner side wall of the outer shell 300 is provided with wave-shaped raised stripes 200, a heat dissipation cavity 400 is formed between the inner side wall of the outer shell 300 and the outer side wall of the inner shell 100, the outer side wall of the outer shell 300 is provided with an air inlet 310 and an air outlet 320, and both the air inlet 310 and the air outlet 320 are communicated with the heat dissipation cavity 400; and the fan device 500 is installed at the air outlet 320 of the shell 300.
When the motor works, heat generated in the motor is transferred to the inner shell 100, the heat is transferred to the heat dissipation cavity 400 through the inner shell 100, the fan device 500 is started, and the fan device 500 extracts and discharges the heat in the heat dissipation cavity 400 to the external environment in an air draft manner to realize heat dissipation; during air draft, cold air in the external environment enters the heat dissipation cavity 400 from the air inlet 310 at the same time, airflow is formed in the heat dissipation cavity 400, and the airflow brings away heat in the heat dissipation cavity 400; the raised stripes 200 on the outer side wall of the inner shell 100 increase the heat transfer area of the inner shell 100, and meanwhile, the raised stripes 200 on the inner side wall of the outer shell 300 are matched, so that airflow is disturbed in the heat dissipation cavity 400, heat is better discharged out of the heat dissipation cavity 400 along with the airflow, and the heat dissipation efficiency is effectively improved.
In some embodiments of the present invention, the inner casing 100 is provided with a vent hole (not shown), which communicates the inside of the inner casing 100 with the heat dissipation chamber 400; when the motor works, internal heat is transmitted through the inner shell 100 on one hand, and on the other hand, the internal heat can be directly discharged into the heat dissipation cavity 400 through the vent hole, so that the heat dissipation efficiency is further improved.
In some embodiments of the present invention, the blower device 500 includes a mounting base 510 and a blower body 520, one side of the mounting base 510 is rotatably connected to the air outlet 320 through a rotating shaft 530, and the opposite side of the mounting base is fixed to the housing 300 through a screw; when the fan device 500 is installed, the fan device can be directly installed on the housing 300 through the installation seat 510, so that the installation is convenient; when the blower body 520 needs to be repaired, the screws for connecting the mounting base 510 and the casing 300 can be loosened, then the mounting base 510 is opened around the rotating shaft 530, and then the blower body 520 is directly repaired.
