Abstract
A cooling jacket, which is cylindrical and has an axial direction and a radial direction. The outer peripheral wall of the cooling jacket is partially recessed to form a channel allowing a cooling fluid to pass, wherein the channel comprises a plurality of straight sections and a plurality of inclined sections, the extending direction of the straight section is perpendicular to the axial direction, the inclined sections are connected to the straight sections to change the direction of the channel, and at least some straight sections connected to two ends of the inclined sections are used for circulating the cooling liquid in opposite directions.
Claims17
A cooling jacket comprising:
- a cylindrical body having an axial direction and a radial direction, an outer peripheral wall partially recessed to form a channel allowing a cooling fluid to pass therethrough, wherein the channel comprises a plurality of straight sections and a plurality of inclined sections, extending directions of the straight sections are perpendicular to the axial direction, the inclined sections extend along a cylindrical spiral and are connected to the straight sections to change a direction of the channel, and two of the straight sections connected to two ends of at least part of the inclined sections are used for circulating the cooling fluid in opposite directions, wherein the channel comprises at least two sub-channels connected in parallel on a circulating path between a start end and a stop end, and wherein the sub-channels have a first cross-sectional width in a first section and a second cross-sectional width in a second section, the first cross-sectional width being greater than the second cross-sectional width, and the first section of a first subchannel is axially adjacent and coextensive with the second section of the first subchannel in a circumferential direction in the two straight sections connected to two ends of at least part of the inclined sections configured for circulating the cooling fluid in opposite directions.
A motor, comprising a rotor and a stator, and a cooling jacket, the rotor and the stator being arranged on an inner periphery of the cooling jacket wherein the cooling jacket includes an outer peripheral wall partially recessed to form a channel allowing a cooling fluid to pass therethrough, the channel comprising:
- a plurality of straight sections and a plurality of inclined sections;
- the straight sections having extending directions perpendicular to an axial direction;
- the inclined sections extending along a cylindrical spiral and being connected to the straight sections to change a direction of the channel;
- and two of the straight sections connected to two ends of at least part of the inclined sections configured for circulating the cooling fluid in opposite directions, wherein the channel comprises at least two sub-channels connected in parallel on a circulating path between a start end and a stop end, and wherein the sub-channels have a first cross-sectional width in a first section and a second cross-sectional width in a second section, the first cross-sectional width being greater than the second cross-sectional width, and the first section of a first subchannel is axially adjacent and coextensive with the second section of the first subchannel in a circumferential direction in the two straight sections connected to two ends of at least part of the inclined sections configured for circulating the cooling fluid in opposite directions.
