Description
Technical field
The utility model relates to a kind of partial structurtes of centrifugal fan, refers to especially a kind of innovation structure design of combined type centrifugal fan wheel.
Background technique
Radiation fan generally is divided into axial fan and centrifugal cutter (or being called cross flow fan) according to the difference of its diversion space form, and the utility model is inquired into improvement for described centrifugal cutter structure especially.
Existing centrifugal cutter structural design, have and adopt metal material to consist of, also have and adopt plastic material to consist of, for structural volume centrifugal cutter product of certain scale, no matter it adopts plastic material or metal material manufacturing, for the structural strength of finished product, not having difficulty exists, but along with present various electronics, the lightening development trend of computer product, so that the casing volume of product all significantly reduces many than traditional product, it is narrower that its inner space becomes relatively, more limited, but the situation that so causes the containing space of radiation fan significantly to be compressed equally.
Moreover, the centrifugal cutter structure is in case after must implementing lightening design, certainly will begin to face technical difficulty and bottleneck on its structural design, how can take into account its better structural strength and precision again reaching under the condition of lightening specification, unaffected to guarantee its run stability, real still is that relevant industry continues the important topic that thinking breaks through.If with the centrifugal cutter structure that plastic material is made, the thinness that the blade of its impeller can reach is unsatisfactory, and the structural strength behind its thickness thin type and water conservancy diversion dynamics are with undesirable; And if the centrifugal cutter structure made from metal material, though the blade position of its impeller can reach the thin type requirement, its peripheral ends position often has strength deficiency and problem and the scarce frauds such as unstable, that noise is excessive are buffeted in on-stream appearance; Moreover more there are the problems such as difficult forming, manufacture cost height in the trickle or special position of form to the centrifugal cutter made from metal material at some.
Therefore, for the existing problem of above-mentioned existing centrifugal cutter structure, how to develop a kind of innovation structure that has more desirable practicability, must make great efforts again to research and develop target and the direction of breakthrough for relevant dealer in fact.
In view of this, the creator this in manufacturing development and the design experiences of being engaged in for many years Related product, for above-mentioned target, in detail after design and the scrupulous assessment, eventually this creation of a true tool practicability.
