Description

Combination type blade wheel

Technical field

The present invention relates to a kind of axial-flow blower structure.

Background technique

Existing impeller 4, cooperation is referring to shown in Figure 6, described kind of impeller 4 tools one hollow casing 41 described housing 41 inside center are established an axostylus axostyle 44, the periphery of described housing 41 is coaxial with described axostylus axostyle 44, the periphery ring of described housing 41 is established

several pieces blades

42,42 in described blade 42 and blade form air guide channel 45, in view of the above, lead into air guide channel 45 and blow out when existing impeller 4 rotation meetings are entered air by blade 42 leading edges guidings to trailing edge, so but the air guide channel 45 of this kind axial-flow blower 4 is wide outlet area 450 broads, cooperation is referring to shown in the radiator shutter of the novel letters patent book number ZL200320102753.0 of Fig. 7 China, though being provided with supercharging blade 47, the outlet end of air guide channel 45 can reduce outlet area 450 width, but owing to the blade 42 of impeller 4 is so that the outlet area 450 that is its air guide channel 45 of radial setting is understood toward blade 42 tail ends gradually wide, therefore also broad of the outlet area 450 of blade 42 tail ends, so the blade 42 blow out air air guide channel that rebounds back again takes place easily, and its blast is also relatively poor, the shortcoming that the flow field is also random.

Again, the electronic equipment arithmetic speed is more and more fast, and the heat that is produced is also many, how to increase heat dissipation, is the important topic that industry desires to overcome solution.

Summary of the invention

Because the shortcoming of existing impeller, the inventor thinks and innovation, and designs a kind of ring body that utilizes, the space of can smooth and easy flow field and providing the supercharging blade to be provided with, increase the supercharging lobe numbers of impeller, to improve the combination type blade wheel of radiating efficiency, this is the main purpose place of the present invention's design.

For achieving the above object, the technical solution used in the present invention comprises:

A kind of combination type blade wheel is characterized in that, comprising:

A main lobe has housing, several pieces blades, and wherein said housing is a hollow structure, and its outer periphery are equipped with described several pieces blades, form air guide channel between the adjacent blades of described several pieces blades, and described several pieces trailing edges are provided with breach;

A ring body group, has housing, ring body and several pieces interior supercharging blade and outer supercharging blade, wherein the housing of ring body group and ring body are hollow structures, and be the coaxial spaced setting, be connected with supercharging blade in several pieces between the housing of described ring body group and ring body, and establish supercharging blade outside several pieces at described ring body outer periphery ring, the housing of described main lobe docks with the housing of described ring body group, the breach of several pieces trailing edges of described main lobe is socketed on the ring body of described ring body group, interior supercharging blade and outer supercharging blade correspondence are arranged in the air guide channel of main lobe, thereby form combination, described ring body is positioned between the air guide channel posterior marginal zone of described main lobe, it is interior air guide channel and outer air guide channel that described ring body separates the air guide channel of described main lobe, interval corresponding one interior supercharging blade of air guide channel in each is described, the interval of each described outer air guide channel is to there being at least one outer supercharging blade.

So the advantage of structural design has, can smooth and easy flow field and the air that increases blast and suppress the to blow out air guide channel that rebounds back again, and be difficult for demoulding situation to overcome interference of components with combined type.
