PURPOSE:To miniaturize the shape of a cubicle, and to obtain the excellent efficiency of cooling by improving the arrangement of the instrument. CONSTITUTION:Air holes 2-4 are formed to an upper section and a lower section of a side wall and a top wall of the cubicle 1. Cooling radiators 6a-6c to which rectifying elements 5a-5c are mounted are arranged in such a manner that radiation fins are each opposed, paired in the horizontal direction, faced one another at the same interval, and also stacked at every each row at the same interval in the vertical direction. The mounting plates 8a-8c of accessory circuits 7a-7c are inclined to an oblique upper section from the upper outside edges of each cooling radiator 6a-6c and attached, the upper end edges are opposed, and space sections 10a-10c having proper width are formed among the mutual upper end edges of pairs of the accessory circuit mounting plates 8a-8c. Air having a high temperature passing through the cooling radiators is guided by means of the accessory circuit mounting plates, and rises in the space sections. |
