Abstract
A machine with a housing, wherein the housing has a body formed into a cylindrical structure extending along an axial direction. The housing includes a plurality of radiation ribs extending along the axial direction and disposed circumferentially outside the body. Further, the housing includes at least one pair of ventilation windows arranged to radially protrude outward from two ends of the body in the axial direction respectively, so as to dispose a part of the plurality of radiation ribs therebetween; and at least one ventilation duct arranged radially outside the radiation ribs along the axial direction and coupled to the at least one pair of ventilation windows, enabling an internal heat radiating airstream of the electric machine to flow through the ventilation duct. The radiation ribs also can be configured at the position where the ventilation duct is disposed.
