Abstract

PURPOSE: To reverse the wind direction each in the inner and outer circumferential parts by providing the inner and the outer circumferential part where the fan blade is twisted in an opposite direction with a partition cutting in between.
CONSTITUTION: Axial-flow fan 1 is provided in a plural number with blade 2 for the inner circumferential part and blade 3 for the outer circumferential part separated by a partition. The blade 2 for the inner circumferential part and the blade 3 for the outer circumferential part are twisted in an opposite direction. The axial-flow fan 1 is provided in the inner circumferential conductor pipe 5 and the outer circumferential conductor pipe 6 with the inner circumferentinal part 2 and the outer circumferential part 3 opposed to each other. If the wind blows, for instance, in an arrow direction A at the side of inner circumferetinal part 2, it blows in an arrow direction B at the side of outer circumferential part 3. Under this constitution, it is possible to suck and discharge air concurrently with the use of a single axial-flow fan. Consequently, a large air suction/discharge volume can be obtained contrary to the fan device volume.
