Hexagonal volute

Abstract

The invention discloses a hexagonal volute. The hexagonal volute comprises a left side plate, a right side plate and a wrapping plate combined with the left side plate and the right side plate to forma volute, wherein a folding structure is arranged on the position, which is located at the air outlet side of the volute, of the wrapping plate; the folding structure on the wrapping plate is combined with the two side plates to form a hexagonal structure on the air outlet side; and the air outlet of the volute is formed by the hexagonal structure in a surrounding manner. According to the hexagonal volute disclosed by the invention, the folding treatment is carried out on the wrapping plate and the wrapping plate is combined with the two side plates to form a hexagon, so that compared with atraditional volute, the hexagonal volute has the advantage that the uniformity of the outlet air is obviously improved, the loss of the air volume is reduced and the air flow noise is reduced; and inthe meantime, the wrapping plate and the left and right side plates are connected in an insertion manner at oblique angles, the center line of the air outlet of the volute is basically coincident withthe center line of the volute and an external air pipe and equipment can be basically centered, so that the installation space is effectively reduced and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of centrifugal fan application equipment, in particular to a hexagonal volute. Background technique [0002] The outlet of the volute of the existing fan basically presents a quadrangular shape, that is, the air outlet composed of the volute cladding plate and the two side plates has a four-sided structure. Due to structural reasons, the uniformity of the air outlet is poor, the air volume loss is large, and the airflow noise is high. At the same time There is a large deviation between the center line of the air outlet and the horizontal center line of the volute, and the external air duct installed in the whole machine needs to be made eccentrically. [0003] In order to solve the above problems, this case was born. Contents of the invention [0004] (1) Solved technical problems [0005] The purpose of the present invention is to overcome the disadvantages of the prior art, and provide a hexagonal volu...
