Detailed Description
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.
As shown in fig. 1-2, a motor casing comprises a body 1, wherein cylinders 14 are concentrically arranged in the body 1; the front end of the body 1 is provided with a plurality of first arc-shaped grooves 11 which are uniformly distributed at equal angles along the circumferential direction, and correspondingly, the front end of the body 1 is provided with the same number of second arc-shaped grooves 12 which are uniformly distributed at equal angles along the circumferential direction; the first arc-shaped grooves 11 and the second arc-shaped grooves 12 are distributed at intervals and are concentrically wound outside the cylinder body 14, the bottom of each first arc-shaped groove 11 is provided with an exhaust hole 13, each first arc-shaped groove 11 is also internally provided with an open slot 2, the inner end of each open slot 2 is hermetically fixed on the bottom surface of the corresponding first arc-shaped groove 11, the opening of each open slot 2 is hermetically fixed on the outer peripheral surface of the cylinder body 14, a heat dissipation channel 17 is formed between each open slot 2 and the cylinder body 14, and the opening at the front end of each exhaust hole 13 is communicated with the heat dissipation channel 17; a plurality of air inlet holes 16 are formed in the bottom surface of each second arc-shaped groove 12, correspondingly, a plurality of air inlet pipes 3 are arranged in each second arc-shaped groove 12, the number of the air inlet pipes 3 is the same as that of the air inlet holes 16, and the inner ends of the air inlet pipes 3 are respectively fixed at the front end openings of the air inlet holes 16 in a sealing mode.
