形成してなるプリント板冷却キヤビネツト。 A small housing-shaped shelf that accommodates a group of printed boards on which a large number of semiconductor elements are mounted side by side at regular intervals and allows air intake and exhaust to flow freely on the top and bottom surfaces, and a shield that is diagonally partitioned in a front and rear diagonal manner between at least one pair of left and right side wall plates that face each other. In a cabinet in which intake and exhaust ducts with plates interposed are alternately attached to the cabinet frame and stacked in multiple stages, the intake and exhaust duct groups are turned upside down and the air intake and exhaust ducts in the shelf group are adjusted to match the flow of air conditioning in the installed room. A printed board cooling cabinet with a structure that allows intake and exhaust flow to be reversed.
