Abstract:
1. A cooling device of an electronic apparatus that includes a plurality of members juxtaposed such that their surfaces confront each other, the surface of at least one of the members comprising a heat discharge surface from which heat is discharged, said cooling device comprising: a first air-cooling part equipped with a first opening provided confronting a first side surface of a unit that includes said plurality of members, said first side surface intersecting with a plane that contains said heat discharge surface, wherein a first air flow emitted from said first opening flows in a first direction toward a reference point set on said heat discharge surface; a second air-cooling part equipped with a second opening provided confronting a second side surface of said unit, said second side surface being adjacent to said first side surface and intersecting with a plane that contains said heat discharge surface, wherein a second air flow emitted from said second opening flows toward said reference point in a second direction that intersects with said first direction; a first duct that communicates with said first opening; and a second duct that communicates with said second opening, wherein, taking as a boundary a second line that passes through said reference point and that crosses at right angles with a first line that joins said reference point and a center of an opening width of said first opening in a sectional plane parallel to said heat discharge surface, a center in an opening width of said second opening in a sectional plane parallel to said heat discharge surface is located on a side opposite the side in which said first opening is provided, wherein said second duct is configured to extend along said second side surface, an end of said second duct including a wall part provided with a surface that is perpendicular to a direction of an advance of an air flow that flows through the second duct, and wherein said second opening is provided to adjoin said wall part of the end of said second duct.
