Abstract: The present invention proposes an onboard computer equipped with a stand-alone aeraulic cooling device. Its main benefit is that it improves the effectiveness of the aeraulic cooling of onboard computers, thanks to the provision of ducts (N1, N2, N3) routing a cool air stream (FA) to the hot spots of the electronic modules (E1, E2, E3, E4).

Abstract: The invention relates to an electronic device operating in difficult environments. The electronic device comprises at least one printed circuit board supporting heat-dissipating electronic components, a heat sink, a first side of which is in contact with electronic components on a first side of the printed circuit board, and a second side of which is designed to evacuate heat by convection, characterized in that it also comprises a cover delimiting a channel in which a coolant circulates to ensure convection, the cover being joined to the heat sink and the printed circuit board, and in that the channel prevents the coolant from coming into contact with the electronic components.
