PROBLEM TO BE SOLVED: To provide an enclosure unit housing rack which improves heat exhaust efficiency for a plurality of vertically stacked and housed enclosure units.SOLUTION: The enclosure unit housing rack comprises: a plurality of air duct bodies which are provided oppositely to each other on the backs of a plurality of enclosure units housed in a rack body for guiding hot exhaust air exhausted from the enclosure units to a deep space of the rack body; and air exhaust fins which are provided on rear end faces at a side opposite to openings of the air duct bodies opposing to the backs of the enclosure units for exhausting the hot exhaust air introduced into the air duct bodies towards portions which are different from each other in a width direction in the deep space of the rack body. Lengths of the air duct bodies in a depth direction are made short successively from a lower-stage side to an upper-stage side of the rack body, and a width between couples of the heat exhaust fins provided in the air duct bodies is made wider successively from the upper-stage side to the lower-stage side of the rack body. |
