Integrated water cooling shell of motor

Abstract

The invention belongs to the technical field of motor shells, and relates to an integrated water cooling shell of a motor. A spiral heat dissipation water channel integrally formed with a cylinder is in a side wall of the motor shell formed by a lower end cover integrally formed at one end of the cylinder; a water inlet and a water outlet at the upper and lower ends of the spiral heat dissipation water channel pass through the side wall of the cylinder; a wiring box, a lifting lug and at least three reinforcing rib type protrusion ridges integrally formed with the cylinder are on the outer wall of the cylinder; the three reinforcing rib type protrusion ridges are arranged at intervals in the circumferential direction; the axes of the three reinforcing rib type protrusion ridges are in the vertical direction; the lower head face of the wiring box is aligned to the lower head face of the lower end cover; furthermore, a through hole passing through the cavity of the cylinder is arranged on the lower head face at the joint of the wiring box and the lower end cover; threaded blind holes are arranged on the upper and lower head faces of the motor shell at intervals in the circumferential direction; an axial hole passing through the axis of the cylinder is arranged on the lower end cover; and the motor shell is cast on a shaft sleeve, so that the shaft sleeve is located on the inner wall of the axial hole. The integrated motor shell is good in thermal conductivity and heat dispersion and low in fault rate and production cost and is applicable to motor shells of electric passenger automobiles.

Description

technical field [0001] The invention belongs to the technical field of motor casings, in particular to an integrated motor water-cooled casing. Background technique [0002] With the rapid development of electric vehicles, the number of motors used in automobiles has also increased. The motors of passenger electric vehicles generate a lot of heat due to their high power. Good heat dissipation has become the key to motors used in passenger electric vehicles. The current The cooling methods include fan cooling and spiral water channel or water jacket cooling. Most of the spiral water channels or water jackets are welded on the outer surface of the motor shell to connect the spiral water channel or water jacket. The disadvantages are complex production process, high production cost, and failure rate. High, poor cooling effect. Contents of the invention [0003] The purpose of the present invention is to provide an integrated motor water-cooled casing. [0004] The purpose o...
