Abstract

PURPOSE: To blow a cooling air to a heating part effectively by a method wherein an introducing passage for the cooling air for the interior of an outer frame is thermally insulated from discharge air from a blower, and a suction fan is directly connected to an outer end of a rotary shaft of the blower.
CONSTITUTION: A scroll pipe 17 is provided so as to directly connect the air discharge port of a blower 12 with a discharge port at an outer plate of an outer frame 13, the passage 20 for introducing the cooling air for the interior from outside is provided to be thermally insulated from the pipe 17 and the discharged air, a suction fan 18 for cooling air is directly connected to the outer end of the rotary shaft of the blower 12, and an opening 19 in the outer frame 13 of a passage 20 is provided oppositely to the fan 18. Therefore, the air taken into the interior of the outer frame by the fan 18 can be effectively introduced without being affected by the hot discharged air, and the fan is fitted in the vicinity of the blower pulley 14 which is most easily heated to a high temperature, so that the cooling air can be efficiently introduced to a high temperature part.
