Device with integrated electronic components equipped with a partition for separating ventilated areas

Device (1) with integrated electronic components (2) which comprises unecarte (3) forming a support for said components (2), a cover (4) mounted surladite card (3) to cover said components (2) and a partition (30) dividing that extends from the cap (4) to the card (3) sensiblementperpendiculairement thereto, said partition (30) separating two zonesdistinctes (A, B) of the card (3), characterized in that it comprises an overcover (32) covering the cover (4) and defining an internal space between the cover (4) and the overcover (32) in which there are provided cooling Degaz distribution means (36) defining two side gaps ( 38, 40) separate the internal space (34), an upstream secondary space (38) danslequel the cooling gas is adapted to be injected and a downstream espacesecondaire (40) wherein the cooling gas is adapted to so êtreévacué such that cooling gas injected into the zoneamont (B) of the card (3) is directed toward the downstream secondary space (40) del'espace internal (34) and that cooling gas injected into the upstream espacesecondaire ( 38) of the internal space (34) is directed toward the downstream zone (A) of the card (3).
