    摘要: The present invention concerns a protective cover (400) designed to cover power, filtering and control modules of an electronic assembly for a rotating electric machine for a motor vehicle. Said protective cover (400) is characterised in that it comprises: - openings (401, 402, 403, 404) designed to generate different cooling air streams (F1, F2, F3, F4) for heat dissipation requirements of each of the power, control and filtering modules; - the openings of the protective cover (400) being distributed into: a first set of openings (401) designed to be positioned facing the fins of a first heat sink coupled to the power module; a second set of openings (402) designed to be positioned facing the control module; the two sets of openings (401, 402) being separated by a barrier wall (405) so as to create a first radial cooling air stream (F1) for said power module and a second radial cooling air stream (F2) for said control module; and a third set of openings (403) designed to be positioned facing the fins of a second heat sink coupled to condensers of the filtering module so as to create a third radial cooling air stream (F3) for said filtering module.
