Patent attributes
A ventilation device (1) is proposed, in particular designed to ventilate a circuit board (2), preferably in or for a computer, wherein the ventilation device (1) is designed to produce a first cooling air stream (5) from a first fan (12) and to produce a second cooling air stream (7) from a second fan (13), wherein the first cooling air stream (5) and the second cooling air stream (7) flow through on different sides of an air stream boundary plane (L), preferably parallel to the air stream boundary plane (L), through a common ventilation plane (BL) perpendicular to the air stream boundary plane (L), wherein the directions of flow from the first fan (12) and the second fan (13) are crosswise to the air stream boundary plane (L), wherein the ventilation device (1) preferably is designed to be mountable such that the air stream boundary plane (L) coincides with a central plane of the circuit board.
