A device for the convective cooling of a drive-train component, e.g. a rare axle differential 1, of a motor vehicle comprises a thin walled shaped flow body 15 having a shell-type formation which provides a gap 17 for passage of air between a shell-type region (16, fig 3) of the flow body 15 and an underside of the rare axle differential 1. When the vehicle is moving, cold ambient air from underbody flow is guided into the gap 17 and consequently deflected by the flow body 15 to a hot region of the differential 1. Air flow enters the gap 17 substantially parallel to the underbody and issues from the gap 17 in a direction of the underbody. The flow body 15 may be fixed to a rare transmission housing part 2 by means of two lower screws 10 which also screws together housing parts 2 and 3.
