Patent ID: 8450891

Claim:
A current rectifying device for rectifying the current of a polyphase rotary electrical machine provided with an axial axis of symmetry (X-X) and comprising a bearing ( 50 ) having a bottom ( 56 ) transverse-oriented in relation to the axial axis of symmetry (X-X) of the machine, the bottom ( 56 ) provided with through-openings ( 51 ) for a coolant and bearing the current rectifying device; the current rectifying device comprising at least one AC-DC rectifier module ( 100 ) including a holder ( 10 , 16 ) bearing current rectifying members ( 93 , 94 ) having the same phase of the machine; the holder ( 10 , 16 ) of the AC-DC rectifier module ( 100 ) including a heat sink ( 16 ) with vanes ( 18 ) at least partially covering one of the openings ( 51 ) of the bearing ( 50 ); the heat sink ( 16 ) including a base ( 19 ) and the vanes integral with the base ( 19 ); the holder ( 10 , 16 ) including an electrically-conductive plate ( 10 ) carrying the current rectifying members ( 93 , 94 ) and separate from the heat sink ( 18 ); the electrically-conductive plate ( 10 ) being integral with the base ( 19 ) of the heat sink ( 16 ); the electrically-conductive plate ( 10 ) of the AC-DC rectifier module ( 100 ) being integrated with the heat sink ( 16 ) by latching with the aid of an electrically-insulating plate ( 400 ) resting on an external face of the plate ( 10 ) of the module ( 100 ) and having at least one deployable hooked fastener ( 401 ) such that a hook of the fastener ( 401 ) engaging an outer edge ( 280 ) of an aperture ( 180 ) delimited by two consecutive vanes ( 18 ) of the heat sink ( 16 ).
