Abstract

PURPOSE: To make sufficient motor-driven cooling efficiency obtainable in such a way that a multitude of opening ports are arranged in a row along circular direction around the peripheral part of the front bulkhead of a boss on a fan, it is made to be a centrifugal radial blower structure which is formed by a cylindrical part, an annular plate part and a rib.
CONSTITUTION: When blowing, air on the front side of a boss 2a on a fan 2 is inhaled by air flow on the peripheral side of the boss 2a, the front side of the boss 2a comes to be negative pressure while the rear side comes to be positive pressure under continuous blowing draft. And, in concurrence of forcibly sending air in the interstice 4 between the boss 2a of the fan 2 and motor 1 into the front edge peripheral part of the boss 2a by a centrifugal radial blower structure formed by an opening port 2e, a cylindrical part 2f, an annular part 2g and a rib 2h which are multitudinously arranged in a row along circular direction around the peripheral part of the front bulkhead 2c of the boss 2a with getting air to flow from the rear side of the fan 2 through the opening port 5 into the interstice 4, air flow which is engendered in a large quantity as shown as arrow (A) cools off sufficiently the motor 1.
