SYNCHRONOUS WIND WHEEL HAVING MULTIPLE ROWS OF TURBOFANS
Document Type and Number:
WIPO Patent Application WO/2022/100330
Kind Code:
A1
Abstract:
A synchronous wind wheel having multiple rows of turbofans, comprising at least two blade rings (1) which are sequentially and coaxially arranged from inside to outside. Each blade ring (1) comprises a plurality of fan blades (2) which are evenly distributed on the circumference, and the adjacent blade rings (1) are connected into a whole by means of a support (3). The synchronous wind wheel having multiple rows of turbofans is simple in structure; at least two blade rings (1) synchronously rotate and jointly suction air, the air pressure and the air volume are increased, the air collecting efficiency is high, and the whole synchronous wind wheel can be thinned, so that the size is smaller.
