Disclosed is an improved rectifier assembly for use in a rotor of a dynamo electric machine which includes a tubular housing receiving a stack of plates sandwiching diode wafers between studs on certain of the plates and confined by annular ridges on others of the plates. The plates are provided with coolant passages with the coolant passages on adjacent plates being staggered to provide improved impingement cooling.

A rectifier assembly adapted to be mounted in a generator rotor for rotation therewith comprising: a generally tubular housing; a stack of relatively thin plates formed of thermally and electrically conductive material within said housing; at least one face of some of said plates including an axially directed annular ridge centrally of the face and defining a recess; at least another face of others some of said plates having a central, axially projecting stud aligned with a recess in the adjacent face of the adjacent plate; a diode wafer within each said recess; means for applying a compressive pressure to said stack to bring said plates, studs, and wafers into good thermal and electrical contact; electrical conductors extending through said stack and in electrical contact with predetermined ones of said elements and electrically isolated from predetermined others of said elements; and means for flowing a coolant through said housing including non-aligned apertures in said plates.
