Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] Such as figure 1 with figure 2 As shown, according to a specific embodiment of the present invention, a fan volute is provided. The fan volute includes a bottom plate 10 and side plates. The side panels are connected to the bottom panel 10 . An air channel is formed between the bottom plate 10 and the side plate, and the outlet of the air channel has a diffuser section 40 . The side plates include a first side plate 20 and a second side plate 30 corresponding to the diffuser section 40 . Wherein, the second side plate 20 forms an acute angle with the plane where the bottom plate 10 is located.

[0032] In this embodiment, the second side plate 30 in the diffuser section 40 is incl...

Abstract

The invention provides a fan, fan volute and an air conditioner. The fan volute comprises a bottom plate and side plates, wherein the side plates are connected to the bottom plate; an air flue is formed between the bottom plate and the side plates; the outlet of the air flue is provided with a pressure diffusing section; the side plates comprise the first side plate and the second side plate which correspond to the pressure diffusing section; and the second side plate and the bottom plate form an acute-angle included angle on the plane. The second side plate in the pressure diffusing section is inclined by certain angle, so that flowing space, in the fan volute, of a fluid is increased, and turbulence generated when gas enters the fan is reduced, and therefore, the purpose of reducing noises is realized.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a fan, a fan volute and an air conditioner. Background technique [0002] In the prior art, the aerodynamic noise of the fan is mainly composed of rotation noise and eddy current noise. The rotation noise of the fan is the noise generated by the pressure pulsation of the surrounding gas caused by the evenly distributed blades on the fan hitting the surrounding gas medium. However, the rotational noise contributes a large amount to the total value of fan noise, and reducing the rotational noise of fans has become an urgent task in the technical field of fans and air-conditioning equipment. Contents of the invention [0003] The main purpose of the present invention is to provide a fan, a fan volute and an air conditioner, so as to solve the problem in the prior art that the fluid flow space of the fan is small. [0004] In order to achieve the above object, ...
