Abstract
A support frame for a ventilation device for cooling a fluid passing through a cooling circuit of a motor vehicle is disclosed. The frame has an opening defining an opening perimeter configured to receive an impeller, and a central support positioned at the center of the opening and shaped to receive a motor actuating said impeller to generate a ventilation flow. The central support is attached, through said opening, to the frame by at least six holding arms, at least three of which are placed in a first plane or cone of revolution, and another three of which are being placed in a second plane or cone of revolution, different from the first. The first holding arms are each separated from any second holding arm at the opening perimeter by a space covering at least a distance corresponding to a chord of said first holding arms.
