Document Type and Number:
WIPO Patent Application WO/2020/143153
Kind Code:
A1
Abstract:
Provided are a cross-flow wind wheel and an air conditioner, wherein the cross-flow wind wheel comprises a blade (10), in the cross section of the blade (10), the intersection points of the wing-shaped center line of the blade (10) and the outer side end and the inner side end of the blade (10) are defined as an outer side end point A and an inner side end point B, the connecting line of the outer side end point A and the inner side end point B is defined as the chord length L; the blade (10) has the maximum thickness and it is limited by a connecting line of two points DE of the blade (10); the tangent line of the point D of the blade (10) is vertical to the DE connecting line; the vertical connecting line of the D point of the blade (10) and the AB connecting line is defined as a DC connecting line, satisfying: 58% ≤AC / AB <61%. By optimizing the wing-shaped structure of the blade and improving the position distribution and change of the maximum thickness of the blade, the airflow flowing resistance can be effectively reduced, airflow separation is delayed, further the air volume loss, power and noise are reduced.
