Abstract
PURPOSE: To excellently cool the inside of a switch box, by increasing the quantity of flowing air without enlarging an exhaust hole.
CONSTITUTION: A plate 16 with a number of small holes is formed in shapes, such as, triangle, semicircle, which become more distant in proportional to advance to a center portion of an exhaust hole 12 from one end of the exhaust hole and approach to the exhaust hole in proportional to second advance to the other end from the center portion. Consequently, the metallic plate 16 is tilted only by an inclined plane 18 as compared to the size of the exhaust hole 12 and heightened the exhaust area of air becomes large, and more air corresponding to only the portion can be exhausted, thus further cooling electric machinery and apparaturs, such as, three- phase buses 9, in a switch box 2.
