Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, a single-phase motor temperature protection apparatus 100 includes: motor body 10, controller and metal can 20. The metal case 20 is used to house a controller. The motor body 10 includes a metal motor case 30. The metal case 20 is fixed to the metal motor case 30. The controller is disposed in the metal case 20. The controller is provided with a radiating fin. The heat sink is attached to the inner wall surface of the metal case 20. The single-phase motor temperature protection apparatus 100 further includes: a wind-collecting cover 40 and a centrifugal fan 50. The centrifugal fan 50 is used to cool the motor body 10. The wind collecting cover 40 is fixed to an end of the metal motor case 30 away from the motor shaft. The centrifugal fan 50 is disposed in the air collecting cover 40. Specifically, the wind collecting cover 40 is formed in a horn shape. The outer wall surface of the metal motor case 30 is provided with a plurality of heat dissipating rib groups 31. Each heat dissipation rib group 31 includes a plurality of heat dissipation ribs 311. The heat dissipation ribs 311 are formed to protrude outward from the outer wall surface of the metal motor case 30. A ventilation gap 312 is formed between two adjacent heat dissipation ribs 311. The metal case 20 is fixed to the top end of the heat dissipation rib 311 of one heat dissipation rib group 31 and connected to the heat dissipation rib 311. The centrifugal fan 50 forces the airflow into the cowl 40 to move along the ventilation gap 312.
The outer wall surface of the metal case 20 is connected to the heat dissipating rib group 31, and the heat dissipating fins are attached to the inner wall surface of the metal case 20, so that the heat of the heat dissipating fins is transferred to the inner wall surface of the metal case 20. When the centrifugal fan 50 pushes the airflow into the wind collecting cover 40, the airflow is blown along the ventilation gap 312 toward the metal box 20, so as to improve the heat dissipation effect of the metal box 20.
As a specific embodiment, one end of the motor body 10 extends into the wind collecting cover 40. Specifically, a chamfer structure is provided at an end of the motor body 10 extending into the wind collecting cover 40.
As a specific embodiment, the number of the centrifugal fans 50 is the same as that of the heat dissipating rib groups 31. The number of the heat dissipating rib groups 31 is 4. The 4 heat dissipation rib groups 31 are uniformly distributed around the motor body 10. The number of centrifugal fans 50 is 4. The 4 centrifugal fans 50 are evenly distributed around the motor body 10. Specifically, the axes of the 4 centrifugal fans 50 are parallel to each other.
As a specific embodiment, the axial direction of the centrifugal fan 50 is parallel to the longitudinal direction of the heat dissipating ribs 311.
As an alternative embodiment, the number of centrifugal fans is 1; the axis of the centrifugal fan is coincided with the axis of the motor body. I.e. one larger centrifugal fan is used instead of a plurality of smaller centrifugal fans.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
