The invention claimed is: 1. Device with integrated electronic components, that comprises a board forming a support for the components, a cover mounted on the board to cover the components, and a separating partition which extends from the cover to the board substantially perpendicularly to the latter, the partition separating two distinct zones of the board in which electronic components are placed, cooling gas being able to be injected into one of the two distinct zones of the board called the “upstream zone”, and able to be discharged into the other of the two distinct zones of the board, called the “downstream zone”, wherein it comprises an overcover covering the cover and defining an internal space between the cover and the overcover in which are provided cooling gas division means delimiting two distinct secondary spaces in the internal space, an upstream secondary space into which cooling gas is able to be injected and a downstream secondary space into which cooling gas is able to be discharged so that cooling gas injected into the upstream zone of the board is directed toward the downstream secondary space of the internal space and that cooling gas injected into the upstream secondary space of the internal space is directed toward the downstream zone of the board. 2. Device according to claim 1, wherein the cooling gas division means comprise at least one pair of deflectors associated with at least one pair of orifices provided in the cover on either side of the separating partition, at least one deflector opening into the downstream secondary space and at least one deflector opening into the upstream secondary space. 3. Device according to claim 2, wherein the deflectors are distributed in a symmetrical manner relative to the separating partition. 4. Device according to claim 2, wherein the deflector comprises a beveled zone of increasing thickness with an edge that is substantially indistinguishable from the overcover and another edge substantially indistinguishable from the cover. 5. Device according to claim 4, wherein the edge substantially indistinguishable from the cover of the beveled zone of the deflector forms a leading edge for a deflector situated in the upstream secondary space and a trailing edge for a deflector situated in the downstream secondary space. 6. Device according to claim 4, wherein the edge substantially indistinguishable from the overcover of the beveled zone of the deflector forms a trailing edge for a deflector situated in the upstream secondary space and a leading edge for a deflector situated in the downstream secondary space. 7. Device according to claim 2, wherein each deflector comprises a substantially quadrangular central zone, and a triangular zone forming a pointed end, the height of each of the central zone and the triangular zone being equal to the distance between the cover and the overcover. 8. Device according to claim 2, wherein each deflector is made of a nonflammable material, for example of the polymer type. 9. Device according to claim 2, wherein each deflector is made of an electrically conductive material, for example of the metal type or of the filled or coated polymer type. 10. Method for cooling two distinct zones of a device with integrated electronic components that comprises a board forming a support for said components, a cover mounted on said board to cover said components, and a separating partition which extends from the cover to the board substantially perpendicularly to the latter, said partition separating the said two distinct zones of the board in which the said electronic components are placed, cooling gas being able to be injected into one of the two distinct zones of the board called the “upstream zone”, and able to be discharged into the other of the two distinct zones of the board, called the “downstream zone”, wherein it comprises a step of passing cooling gas via gas division means provided in an internal space between the cover and an overcover delimiting two distinct secondary spaces in the internal space, an upstream secondary space into which cooling gas is injected and a downstream secondary space into which cooling gas is discharged so that cooling gas injected into the upstream zone of the board is directed toward the downstream secondary space of the internal space and that cooling gas injected into the upstream secondary space of the internal space is directed toward the downstream zone of the board.
