Abstract
The invention relates to a cooling device for a printed circuit card and to its production process. It is constituted by a parallelepipedic copper frame, to one face of which is fixed the card. The frame is open on two opposite lateral faces orthogonal to the first face. Copper partitions, orthogonal to the first face, define passages through which the liquid or gaseous cooling fluid flows. Gaps can be made orthogonally to the first face for the passage of the fastening clips of the components. Application to printed circuit cards equipping airborne equipment.
