Abstract

The invention discloses a centrifugal wind wheel which comprises a wheel hub and a plurality of blades. The blades extend backwards from the wheel hub in a direction parallel to a rotating shaft of the centrifugal wind wheel; the blades are distributed in a parabolic radial manner; a rear end contour line of each blade comprises a first arc section extending outwards and backwards from the rotating shaft, thereby forming a wind collection area among the blades. A rear wind inlet and two front wind outlets are formed in a volute matched with the centrifugal wind wheel, wind inlet and wind outlet positions are changed, and wind outlet points are increased, so that the wind outlet efficiency is improved. Correspondingly, the wind collection area corresponding to the rear wind inlet is formed in the centrifugal wind wheel, so that more air flow can be collected and is discharged in a centrifugal direction by the action of the blades, and the wind outlet efficiency is ensured.

Description

technical field [0001] The invention relates to centrifugal wind wheel technology, in particular to a centrifugal wind wheel. Background technique [0002] In the past, the central axis of the air inlet and the central axis of the air outlet of the centrifugal fan were two vertical and non-intersecting spatial straight lines. Applications in specific environments such as the same direction as the air intake. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention needs to provide a centrifugal wind wheel. [0004] The centrifugal wind wheel of the embodiment of the present invention comprises: [0005] hub; and [0006] A plurality of blades extending backward from the hub along a direction parallel to the rotating shaft of the centrifugal wind rotor, the plurality of blades are arranged radially in a parabola, and the rear end contour line of each blade in...
