The same or similar reference numerals in the drawings of the embodiments of the present invention correspond to the same or similar components; in the description of the present invention, it should be understood that if there is an orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. based on the orientation or positional relationship shown in the drawings, it is only for convenience of describing the present invention and simplifying the description, but it is not intended to indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and are not to be construed as limiting the present patent, and the specific meaning of the terms may be understood by those skilled in the art according to specific circumstances.
The first embodiment is as follows:
the present embodiment is described below with reference to fig. 1 and 2, and the present invention relates to a motor, and more specifically to a centrifugal fan structure of a mixed flow ventilation motor, which includes a bearing assembly 1 and a cooler 4; 4 bottoms of 1 top fixed connection coolers of bearing assembly, prevent when having traditional cooling function that the torrent from getting into near bearing assembly 1 and heat bearing assembly 1, when can guaranteeing that motor cooling ventilation effect does not receive any influence, prevent that 1 high temperature of bearing assembly is too high, and then reduce the type test unqualified and the various trouble of bearing high temperature that the bearing high temperature arouses.
The second embodiment is as follows:
the present embodiment will be described with reference to fig. 1 and 2, and the present embodiment further describes the first embodiment, in which the top of the wind deflector 3 is fixedly connected to the inside of the bearing assembly 1.
The third concrete implementation mode:
the present embodiment is described below with reference to fig. 1 and 2, and the present embodiment further describes the first embodiment, in which the bearing assembly 1 is fixedly connected to the bottom of the centrifugal fan 2; the centrifugal fan 2 is located on the wind shield 3 side.
The fourth concrete implementation mode:
the present embodiment will be described with reference to fig. 1 and 2, and the present embodiment will be described with reference to the first embodiment, in which one end of the cylinder 5 is fixedly connected to the outside of the centrifugal fan 2.
The fifth concrete implementation mode:
the present embodiment will be described with reference to fig. 1 and 2, and the present embodiment will be further described with reference to the first embodiment, in which the other end of the cylinder 5 is fixedly connected to the inside of the bearing assembly 1.
The sixth specific implementation mode:
the present embodiment is described below with reference to fig. 1 and 2, and the present embodiment further describes the first embodiment, the top of the cylinder 5 is fixedly connected to the top of the small fan 6, and the centrifugal fan 2 is added with the cylinder 5 and the small fan 6 to prevent the turbulent flow part from entering the vicinity of the bearing assembly 1, improve the temperature of the hot air end bearing, improve the quality of the motor, and further reduce various faults of unqualified type test and high temperature of the bearing caused by overhigh temperature of the bearing.
