Abstract
A composite low-noise blade of fan comprises a hub and several long blades uniformly distributed on the edge. The invention is characterized in that: the end of around the long blades is connected to a base ring; the inner annular wall of the base ring between the long blades is arranged with at least one short blade toward the wind. The short blade synchronously rotating with the long blade can improve the wind inlet face of blade to feed wind uniformly everywhere and reduce the noise impacted with air.
Description
Technical field
What the present invention relates to is fan part, especially a kind of combined type fan flabellum with low noise.
Background technique
The flabellum of existing fan is made up of the isometric blade that wheel wheel and equi-spaced apart are arranged on the periphery of wheel wheel usually.The fan of this structure flabellum is housed, and during high speed rotating, noise is bigger.
Summary of the invention
Technical problem to be solved by this invention is to remedy the defective that prior art exists, and proposes a kind of combined type fan flabellum with low noise that reduces fan operation noise.
Technical problem of the present invention is solved by the following technical programs:
This combined type fan flabellum with low noise comprises: wheel wheel and equi-spaced apart are arranged on the linear leaf on its periphery, it is characterized in that: the sheet end around linear leaf is connected with and its all-in-one-piece basic ring; The basic ring internal ring wall at each linear leaf interval be provided with at least one facing the wind curved surface towards with the corresponding to short blade of linear leaf.
Described short blade lacks 1/3rd at least than linear leaf.
The design principle of combined type fan flabellum with low noise of the present invention is: utilize to be arranged on the peripheral short blade of rotation synchronously of linear leaf, improve the whole air intake surface of flabellum, make each point of flabellum all compare uniform air intake, it can reduce in the flabellum high speed rotating process to agitate with air and contacts formed noise.
The design design science of combined type fan flabellum with low noise of the present invention, rational in infrastructure, simple.This flabellum is compared with the conventional monolayers flabellum under same rotational speed and air quantity situation, and noise reduction is very obvious.Can save the air-guiding aisle of axial fan flabellum outside in addition in some cases.
The concrete structure of combined type fan flabellum with low noise of the present invention is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation of combined type fan flabellum with low noise.
Embodiment
Embodiment: can be clear that from Fig. 1 this is a kind of combined type fan flabellum with low noise that is applicable to that the computer CPU radiating fin is installed, it comprises: be arranged on the flabellum that the linear leaf 2 on its periphery constitutes by wheel wheel 1 and equi-spaced apart, by basic ring 31 and the equi-spaced apart flabellum circle 3 that six short blades 32 on the ring wall constitute that sets within it.Described six short blades 32 are distributed in basic ring 31 internal ring walls at each linear leaf 2 interval; The base circle 31 of described flabellum circle 3 is placed in linear leaf 2 peripheries and is fixedly connected to form one; Described linear leaf 2 is consistent with the curved surface that facings the wind of short blade 32.
Described short blade 32 is than linear leaf 2 short 1/3rd;
The described wheel 1 of taking turns is provided with the electric machine assembly assembly cavity.
Above content be in conjunction with a concrete preferred implementation to the detailed description that the present invention did, can not assert that structural design of the present invention is confined to these explanations.Engineers and technicians for technical field under this without departing from the inventive concept of the premise, can also make some changes and improvements, all should be considered as belonging to the scope of patent protection that the present invention is determined by claims of being submitted to.
Claims (3)
1, a kind of combined type fan flabellum with low noise comprises: wheel wheel and equi-spaced apart are arranged on the linear leaf on its periphery, it is characterized in that: the sheet end around linear leaf is connected with and its all-in-one-piece basic ring; The basic ring internal ring wall at each linear leaf interval be provided with at least one facing the wind curved surface towards with the corresponding to short blade of linear leaf.
