Embodiment 1

[0017] Example 1: see figure 1 , figure 2 , the blade of a fan that uses low-speed wind energy to generate power has a wing body y. In the cross-section of the wing body y, for the convenience of description, the outer contour of the wing body is divided into 10 points, of which 1, 5, 6, and 9 are four points It is the joint point where the streamlined convex curve and the streamlined concave curve are connected. The points 1, 2, 3, 4, and 5 are smoothly connected by the streamlined convex curve to form the wing head a and the wing back b. The shape of the outer contour curve of the wing head a It is streamlined, and its wing back b is a convex streamlined curve; points 6, 7, 8, and 9 are smoothly connected by streamlined convex curves in turn to form a wing tail d, and its wing tail d is also streamlined; points 4, 5, and 6 The wing back b and the wing tail d are smoothly connected by a convex streamlined curve and a concave streamlined curve, so that the wing tail is raise...

Embodiment 2

[0018] Embodiment 2: A wind turbine blade that utilizes low-speed wind energy to generate power has a wing body y, and the wing body y is C-shaped. All the other structures are with embodiment 1.

Abstract

A fan panel utilizing low speed wind to generate power is features as setting cross section of panel body to be forms of using streamline as outline curve of panel head, using projected streamline curve as panel back and using streamline as panel tail; connecting panel head, panel back, panel tail and panel stomach in streamline curve to form closed streamline curve for utilizing low speed wind energy effectively.

Description

Technical field: [0001] The invention relates to a blade of a fan, in particular to a blade of a vertical fan. Background technique: [0002] The design of fan blade airfoil is to establish a physical calculation model on the basis of fluid mechanics. Since the fluid mechanics formula is very complicated and there is no analytical solution, it must be completed with the help of a computer. At present, the calculation model for designing fan airfoils generally adopts the calculation model for designing aircraft airfoils. Since the movement of fan blades relative to the wind is rotational motion, while the movement of aircraft wings relative to the wind is linear motion during flight, the aircraft wing The calculation model cannot design a fan airfoil that fully meets the actual requirements, especially in the case of a vertical fan, the fan blades must experience reverse wind flow during the rotation process, so the designed fan airfoil and the fan blade that meet the actual ...
