LIQUID-COOLED MOTOR FOR BSG AND MOTOR HOUSING AND COOLING STRUCTURE THEREOF

원문 (중국어)

The liquid-cooled motor for BSG includes a motor housing, which has a cooling structure. A cooling structure includes: an outer water jacket; an inner water jacket fitted into the outer water jacket; a first cooling water passage disposed on the inner water jacket; a second cooling water passage disposed on an inverter; a first transfer water passage and a second transfer water passage both disposed on the outer water jacket and a rear end cover. Cooling water enters into the first cooling water passage and the first transfer water passage synchronously from a transfer water inlet, and enters into the second cooling water passage through the first transfer water passage, thereby realizing simultaneous cooling and heat dissipation of a stator, a rotor and the inverter of the liquid-cooled motor for BSG, respectively.
