The frame has a reception area for receiving plug-in cards or circuit boards and a forced ventilation for the reception area. The forced ventilation is provided by a blower arrangement, as well as an air distributor and air collector, by which a vertical cooling air flow through the gaps of the plug-in cards is produced. The air distributor and air collector are juxtaposed in the depth of the frame and separated from one another by a cooling baffle passing diagonally from top to bottom. The outlet-side opening of the distirbutor is located in the frame cover. When several frames are stacked, this opening cooperates with an inlet arranged in the bottom of the frame for the reception area of the frame place at the top.

A ventilated storage assembly for electric circuit boards comprising at least two stacked like frames (10, 100) including a lower frame (10) and an upper frame (100), each frame comprising a base (14), a top (30), a front (15), a back (23) and sides, the base of the upper frame (100) being supported
A ventilated storage assembly for electric circuit boards comprising at least two stacked like frames (10, 100) including a lower frame (10) and an upper frame (100), each frame comprising a base (14), a top (30), a front (15), a back (23) and sides, the base of the upper frame (100) being supported on the top (30) of the lower frame, each frame including a front reception area (13, 13′) at the front of the respective frame for vertically disposed circuit boards, each front reception area extending upwardly from the base of the respective frame, a first air inlet (16, 16′) in the base of each frame communicating with the respective front reception area (13, 13′), an air opening (18) at the top of each front reception area aligned with the respective first air inlet, an air space (25) between the top of each front reception area and the top of the respective frame, a baffle (27) in each air space dividing the space into front (28) and rear (29) air passages, a second air inlet (26) in the front of each frame communicating with the respective front air passage (28), a first air outlet (34) from said front air passage (28) formed in the top of each frame in alignment with the respective first air inlet (16, 16′), a rear reception area (35) in each frame behind the respective front reception area and communicating with the respective rear air passage (29), each rear reception area extending from the top of the respective frame to a level below the top of the respective front reception area, a second air outlet in the back of each frame communicating with the respective rear reception area, and a fan (36, 36′) associated with each second outlet for causing air to flow through the respective frame, the fan (36) of the lower frame being effective for causing air to flow through the first air inlet (16) of the lower frame, the front reception area (13) of the lower frame, the rear air passage (29) of the lower frame, the rear reception area (35) of the lower frame and the second air outlet of the lower frame, and the fan (36′) of the upper frame being effective for causing air to flow through the second air inlet (26) of the lower frame, the front air passage (28) of the lower frame and the first air outlet (34) of the lower frame and hence through the first air inlet (16′) of the upper frame, the front reception area (13′) of the upper frame, the rear air passage of the upper frame, the rear reception area of the upper frame and the second air outlet of the upper frame.
