CROSS-FLOW COOLING FAN DEVICE

Document Type and Number:

WIPO Patent Application WO/1987/003149

Kind Code:

A1

Abstract:

A cross-flow cooling fan device provided within electric appliances which requires cooling, such as an audio amplifier, a microcomputer, a word processor or a copier. In this device, a vane wheel (107) having air-blast slits around the periphery of a central hollow space of a cylindrical body thereof is supported rotatably at both ends thereof on support frames (109, 110) via wheel support shafts (111, 112). Either of a rotary unit consisting of the vane wheel (107) and its support shafts (111, 112), or a stationary unit consisting of the support frames (109, 110) is provided with a field magnet (121), and the other with an armature winding (124) opposing to the field magnet (121), to thereby form a vane wheel-driving unit. This makes it unnecessary to couple an additional motor to the axially-external side of the vane wheel, and enables the cooling fan device to be miniaturized to a great extent.
