Document Type and Number:
WIPO Patent Application WO/2019/085570
Kind Code:
A1
Abstract:
Provided is an air pipe, comprising a first pipe (110) and a second pipe (120) which communicate with each other and are non-collinear. Air passes through the first pipe (110) and the second pipe (120) in sequence; and since the connecting position of the first pipe (110) and the second pipe (120) is of a certain angle, in order to prevent the phenomenon of swirls, and same causing energy loss, and a pressure difference between air coming out of the first and second pipes, a flow guide plate (140) is arranged at the communicating position of the second pipe (120) and the first pipe (110) for removing, by means of the flow guide plate (140), the swirls and turbulent flow caused by the angle when the air flows from the first pipe (110) to the second pipe (120), so that the air transmission efficiency is improved. Provided is a fan system, comprising a centrifugal ventilator and the air pipe. The fan system is high in working efficiency and low in energy loss.
