ELECTRONIC ASSEMBLY FOR A ROTARY ELECTRIC MACHINE FOR A MOTOR VEHICLE

摘要

An electronic assembly for a rotary electric machine for a motor vehicle is disclosed. The electronic assembly includes electronic component blocks having different thermal dissipation needs, the blocks including a power block and a control block. The assembly also includes a device for cooling the blocks and having a protective cover suitable for covering the power and control blocks. The protective cover includes a first set of openings configured to be positioned opposite a first cooling element coupled to the power block, and opposite the control block, the first cooling element being a first dissipator provided with a base plate, the base plate protruding with respect to the power block to create a first radial flow of cooling air (F1) for the power block and a second radial flow of cooling air (F2) for the control block.
