Abstract:
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.
