Abstract:
A cooling and sealing structure of a motor shell, the structure comprising a motor shell (1) and cooling water channels (3) disposed within the motor shell (1), wherein the cooling water channels (3) are distributed in S-shaped structures around the motor shell (1); end surfaces at two ends of the motor shell (1) are provided thereon with sealing structures used for sealing the cooling water channels (3); and an outer surface of the motor shell (1) is provided with a water inlet (4) and a water outlet (5) that are in communication with two ends of the cooling water channels (3).
