SEGMENTED MOTOR COOLING JACKET

摘要

A cooling jacket for an electric motor includes a plurality of jacket portions that are attached to each other to surround a motor stator. Each jacket portion is an extruded component that includes an outer peripheral wall and an inner peripheral wall spaced inwardly from the outer peripheral wall to form a cooling space between the inner and the outer peripheral walls. A plurality of connecting walls extends between the inner and the outer peripheral walls. The connecting walls cooperate with each other to define a plurality of discrete cooling passages within the cooling space of each jacket portion. First and second end caps are mounted to the plurality of jacket portions to enclose the plurality of discrete cooling passages such that a continuous cooling loop is provided through the plurality of jacket portions and the first and second end caps.
