Water-cooled cooling system for drive motor for new energy vehicle

Abstract

The invention discloses a water-cooled cooling system for a drive motor for a new energy vehicle. The water-cooled cooling system comprises a motor housing, wherein the motor housing runs through a metal cylinder structure; a plurality of strip cooling water channels are arranged in a housing wall of the motor housing; the length direction of the strip cooling water channels is parallel to the axis direction of the motor housing; and the cooling water channels are uniformly distributed in a circumference array along the axis of the motor housing. The water-cooled cooling system is simple in structure; and especially cooling water continuously passes through a wall body of the whole motor housing after a circulating cooling water channel structure in the scheme is adopted, so that the circulating cooling water channel structure has the advantage that the cooling effect is significantly improved in comparison with a traditional passive fin cooling structure.

Description

technical field [0001] The invention belongs to the field of electric motors, and in particular relates to a water-cooled cooling system for a drive motor of a new energy vehicle. Background technique [0002] During the operation of the motor, the stator coil will release heat due to the thermal effect of the current. If it is not cooled in time, the internal resistance of the motor will increase, which will affect the performance of the motor and even burn out the motor. The motor shell is the main heat release part of the motor. The existing ones often adopt passive heat dissipation with cooling fins added, and the effect is often not ideal. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a water-cooled cooling system for a new energy vehicle drive motor with higher cooling efficiency. [0004] Technical solution: In order to achieve the above purpose, a water-cooled coo...
