Patent ID: 7019424

Claim:
Current rectifying equipment for rotary electrical machines having an axis and a rear bearing, of the type having a plurality of positive diodes supported by a first support in the form of a plate, a plurality of negative diodes supported by a second support in the form of a plate, carried by the rear bearing, a connecting device ( 9 ) for electrically interconnecting the positive and negative diodes, a cap which overlays said current rectifying equipment and means for generating a forced axial flow (F 1 ) of a coolant fluid flowing in the axial direction of the axis of the machine, the first support for the positive diodes carrying on its front face, which is oriented towards the axis of the machine, cooling fins which extend in said axial flow of the coolant fluid in the radial direction of the machine, wherein said current rectifying equipment includes means for the mixed cooling of the second support for the negative diodes by convection and conduction.
