Abstract
The present invention relates to an electronic assembly (10) for a rotary electric machine (1) for a motor vehicle. Said electronic assembly is characterized by comprising: blocks (100, 200, 300) of electronic components, the blocks having different heat dissipation needs, the blocks being: a power block (100), a filter block (200), a control block (300), and a device (10′) for cooling said blocks (100, 200, 300); said cooling device (10′) comprising: a protective cover (400) suitable for covering the power, filter and control blocks (100, 200, 300), said protective cover comprising openings (401, 402, 403, 404) suitable for generating cooling air flows which differ according to the heat dissipation needs of each of the power (100), control (200) and filter (300) blocks; and cooling elements (101, 201) coupled with said protective cover (400).
