Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1 to 4, in the present embodiment, a middle section of a cross-flow wind wheel with high energy efficiency and large air volume comprises a circular ring-shaped blade disc 1 and a plurality of blades 2 which are integrally formed, wherein each blade 2 is annularly arranged on the bottom surface of the circular ring-shaped blade disc 1, and the upper end of each blade 2 is connected with the bottom surface of the circular ring-shaped blade disc 1. The shape and the specification of each blade 2 are uniform.

In this embodiment, an annular inclined plane 11 that extends backward is formed on the periphery of the top surface of the annular blisk 1, the outer edge of the annular inclined plane 11 extends to the outer edge of the annular blisk 1 to make the outer edge of the annular inclined plane 11 coincide with the outer edge of the annular blisk 1, and the thickness of the outer edge of the annular inclined plane 11 at this time is smaller than that of the top surface of the annular blisk 1, so that the air duct space occupied by the annular blisk 1 is reduced, and the effective air outlet space of the cross-flow wind wheel and the air volume of the cross-flow wind wheel are improved.

Furthermore, the included angle between the top surface of the ring blade disc 1 and the annular inclined surface 11 is 10 degrees

In this embodiment, a plurality of embedded grooves 12 (the embedded groove 12 of this embodiment is partially located on the annular inclined plane 11) are disposed on the top surface of the annular disc, the shape and the specification of each embedded groove 12 are uniform, the bottom surface of each embedded groove 12 is an inclined plane extending obliquely from inside to outside, and the distance from the bottom surface of the embedded groove 12 to the bottom surface of the annular blisk 1 at this time is gradually reduced from inside to outside.

In this embodiment, the lower end of each blade 2 has an inclined end surface 21 extending obliquely from inside to outside, and the distance between the inclined end surface 21 and the bottom surface of the ring-shaped blade disc 1 gradually increases from inside to outside, and the shape of the embedded groove 12 is matched with the lower end of the blade 2, so that the lower end of the blade 2 is embedded and welded in the embedded groove 12 on the top surface of the ring-shaped blade disc 1 of another middle segment. Furthermore, the included angle between the inclined end surface 21 and the transverse section of any point thereof is equal (the included angle is preferably 5 °), and the lower end part of the blade 2 adopts an inclined design, so that the area of the lower end surface of the blade can be effectively increased, and the firmness of welding can be increased.
