PROBLEM TO BE SOLVED: To provide an exhaust fan support structure of a semiconductor power converter in which an exhaust fan body can be extracted in a horizontal direction without providing a maintenance space over an exhaust part.SOLUTION: A centrifugal exhaust fan 18 is supported in an opening part formed on a housing upper part of a semiconductor power converter through a mounting plate 11. The centrifugal exhaust fan comprises an exhaust fan body 15 with a fan mounting plate fixed to an upper part thereof, and an inlet nozzle 13 whose tip is inserted into a suction opening of the exhaust fan body. On top of the mounting plate is formed a surrounding part 12 comprising a pair of guide support side plates for guiding a pair of mutually facing guide parts of the fan mounting plate of the exhaust fan body in the horizontal direction, and a pair of side plates at least one of which is detachable, and on bottom is supported in a vertically movable manner an inlet nozzle mounting plate 14 for fixedly supporting the inlet nozzle 13. |
