Abstract
The utility model provides a wing-shaped blade of a cooling tower fan, which is composed of a blade body and a connection shaft fixedly connected with the blade body, wherein the blade body forms a streamline wing shape. The cross section of a thicker windward side on one side forms an oval hollow structure; the other side is provided with a streamline curved plate. Both ends of the blade body are provided with closed boards. The utility model has the advantages of simple structure, low production cost and extrusion forming, and is used for cooling towers.
Description
Technical field
The utility model relates to the fan blade of doing clammy but usefulness, is meant a kind of blower fan of cooling tower airfoil blade especially.
Background technique
At present, the used for cooling tower fan blade generally adopts aluminum alloy, plastics or glass fibre reinforced plastics manufacturing, and blade body itself all adopts mould compacting or injecting type processing, to equipment, mould and manufacturing requirements height, cause cost higher.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, cost of production is low, can adopt a kind of blower fan of cooling tower airfoil blade of extrusion modling.
The purpose of this utility model is achieved in that a kind of blower fan of cooling tower airfoil blade, form with the coupling shaft of fixedlying connected by blade body with blade body, wherein: described blade body is the streamline wing blade, the sectional shape of windward side, thicker one side is avette hollow structure, another side is the curved plate of streamline shape, and the two ends of blade body are provided with shut.
After the utility model adopted said structure, blade body can adopt disposable extrusion modling, has simplified the production technology of blade, reduces production costs.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model;
Fig. 2 is a schematic cross-section of the present utility model.
Among the figure: 1-blade body, the avette hollow structure of 11-, 12-curved plate, 2-coupling shaft, 3-shut.
