Abstract

PURPOSE: To enhance dust collecting efficiency by a method wherein a position of a dust collecting port is set to a space from a cooling air inlet in a spiral air passage to a semicircle part and dust is collected by utilizing centrifugal force or the like due to a cyclone, to reduce pressure loss.
CONSTITUTION: Cooling air is directed to a top plate side from a bottom plate side in a spiral air passage 14 shown by an arrow X while whirled therein. In this case, dust or the like mixed in the cooling air at an initial period of whirling is flied into a dust collecting chamber 16 from a dust collecting port 15 directly under a cooling air inlet 13 by inertia force when the air is sucked or inertia due to gravity of dust or the like as shown by an arrow Y. The dust or the like not separated by the aforementioned inertia is revolved through the spiral air passage 14 to be directed to a top plate side and pushed to an inner wall side of an outer cylinder 4 by centrifugal force due to a cyclone during revolution and flied into the dust collecting chamber 16 from the dust collecting port 15. The accumulated dust 18 or the like is removed by detaching a part 20a of a side plate 20 to open the dust collecting chamber 16.
