Abstract
The invention concerns a current-rectifying arrangement for rotary electrical machines of the type comprising a support () for a plurality of positive diodes (), a support for a plurality of negative diodes, forming part of the rear bearing of the machine, and a device for cooling by the creation of a forced axial flow of a cooling fluid through the rectifying arrangement, the support for the positive diodes carrying radial cooling fins () on its front face oriented towards the axis of the machine; the positive diode support device () being produced in the form of at least one moulded piece ('), whose face oriented towards the aforementioned axis carries fine cooling fins (). The invention can be used in alternators for motor vehicles.
