Abstract
A cooling system includes a housing. A bottom of the housing has an installation position for installing a stator iron core. The cooling system further includes: an oil inlet cavity and an oil return cavity, an oil inlet and an oil outlet provided on an outer wall of the housing, an oil spraying hole and an oil return hole provided on an inner wall of the housing, and a plurality of oil diverting grooves provided at the bottom of the housing. The oil diverting grooves penetrate through the installation position. A stator component includes a stator iron core and the cooling system. An axial magnetic field motor includes the stator component.
Claims20
A cooling system, comprising a housing, wherein a bottom of the housing has an installation position for installing a stator iron core;
- the cooling system further comprises:
- an oil inlet cavity and an oil return cavity, which are provided in the housing;
- an oil inlet and an oil outlet, which are provided on an outer wall of the housing, wherein the oil inlet is communicated with the oil inlet cavity, and the oil outlet is communicated with the oil return cavity;
- an oil spraying hole and an oil return hole, which are provided on an inner wall of the housing, wherein the oil spraying hole is communicated with the oil inlet cavity, and the oil return hole is communicated with the oil return cavity;
- and
- a plurality of oil diverting grooves provided at the bottom of the housing, wherein the oil diverting grooves penetrate through the installation position.
A stator component comprising a housing, a stator iron core, a coil, a pole shoe, and a stator cover plate, wherein the stator iron core, the coil and the pole shoe are provided in a space defined by the housing and the stator cover plate;
- the coil is provided in an open slot of the stator iron core, wherein the pole shoe is fixed on the stator cover plate, and when the stator cover plate is butted with the housing, the pole shoe can be arranged at a notch of the open slot;
- an outer ring of the stator iron core and the housing define a first cooling space, and an inner ring of the stator iron core and the housing define a second cooling space communicating with the first cooling space;
- a housing wall of the housing is provided with an oil inlet cavity and an oil return cavity, and an outer wall of the housing is provided with an oil inlet and an oil outlet;
- wherein the oil inlet is communicated with the oil inlet cavity, and the oil outlet is communicated with the oil return cavity;
- an inner wall of the housing is provided with an oil spraying hole and an oil return hole, and the first cooling space and the oil inlet cavity are communicated with each other through the oil spraying hole, and the first cooling space and the oil return cavity are communicated with each other through the oil return hole.
