Title:
AIR BLOWING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/158252
Kind Code:
A1
Abstract:
This air blowing device comprises a centrifugal first fan (14), a centrifugal second fan (20), and an air guide part (16). The first fan rotates about a first fan axial center (CL1) and thereby sucks in, from the axial direction of the first fan axial center, air that has flowed out from a heat exchanger (92, 92a, 92b) included in a vehicular air-conditioning device (90) which performs air conditioning inside a vehicle cabin. Further, the first fan blows out the sucked-in air radially outward. The second fan rotates about a second fan axial center (CL2) in the opposite direction from the first fan and thereby sucks in air from the axial direction of the second fan axial center, and blows out the sucked-in air radially outward. The air guide part forms an air guide passage (161). Air blown out from the first fan flows into said air guide passage as a swirling flow that swirls in the same direction as the first fan. The air guide passage guides the flowed-in swirling flow to the second fan while maintaining the swirling direction thereof.
