Abstract

1. Tier-type-forced draught ventilated rack (Fig. 5 and 6) for mounting printed circuit boards, which are insertable into the rack from the front, which are positioned upright in ventilable channels (17) and which are electrically interconnected via plug connectors at the rear and whose front plates (19) form a closed front, except for narrow slots, the forced-draught ventilation system consisting of supply and exhaust pipes (40', 41') arranged vertically along the sides of the rack, of divider plates (54) forming air seals between the various tiers, of air inlet and exit openings (56, 55) above and below the divider plates (54), respectively, for interconnecting the supply and exhaust pipes (40', 41'), respectively, with the tiers, and of ventilators (61) supplying fresh air to the supply pipes (40') whose ends are closed, characterized by the following features : a) The rack (Fig. 5) is assembled of independent, self-supporting stack-elements (11) which are stacked one above the other and positioned on a base (51) and which are rigidly connected to each other and to the base ; b) each stack-element (11) forms a unit, consisting of an inner frame (12), open towards the top and the bottom, subdivided air-tightly into an upper and a lower section of unequal size by a divider plate (54) the larger section being used for mounting the printed circuit boards (18), and consisting of three vertically arranged venting ducts (40, 41, 42) which surround the frame (12) being provided with inlet and outlet openings (55, 56), at the left-hand, at the right-hand and at the rear sides, and which, when stacking the stack-elements (11) join together to the supply and exhaust pipes (40', 41', 42').
