Description
Technical Field
The utility model relates to a motor cooling technology field especially relates to a motor casing, motor and vehicle.
Background
Compared with a shell formed by an inner shell and an outer shell independently, the traditional motor shell formed by integral casting has the advantages of good sealing performance, high structural rigidity and the like, so that the motor shell is widely applied to driving motors of new energy automobiles.
The integrated casting shell is divided into a spiral water jacket and a square water jacket, and the spiral water jacket has less waterway turbulence and dead zone because the 180-degree waterway bend of the square water jacket is not formed, so that the integrated casting shell is applied on a large scale. However, in some high performance drive motor housing applications, such a unitary housing also exposes a drawback in that the area to be cooled is also larger due to the longer length of the high power motor itself. However, the internal cooling structure needs to be cast by a sand core, and the longer the cooling area is, the wider the sand core of the cooling structure is under the same spiral times. Too wide a sand core can lead to insufficient strength of the sand core and obvious increase of casting defect rate.
Therefore, in order to avoid casting defects, high performance motors are generally provided with increased screw turns or with a water jacket having a square-wave shape. However, no matter the number of screw threads is increased or the zigzag water jacket is selected, the cooling water path is longer than that of the traditional motor shell, the pressure drop of the water path is larger, and the requirement on the whole vehicle, especially the whole vehicle cooling water pump with a four-wheel drive structure, is too high. And the clip-shaped water jacket also bears the problems caused by waterway turbulence, dead zones and the like.
