OIL-FILLED ELECTRIC MACHINE

摘要

PURPOSE:To reduce the lowering of cooling effect by preventing the air which flows through a cooler from turning around to the suction side. CONSTITUTION:An air guide 18 is provided to the top of a soundproof wind tunnel 2 of a cooler. The air guide 18 is provided to all over the length of the group of coolers and a gap between the air guide 18 and a wall 12 should be as small as possible. By this air guide, the discharged air is prevented from turning around to a suction inlet so that the efficiency of the cooler is improved.
