Abstract

The invention discloses an impeller assembly, which comprises an impeller and at least one guide ring, the guide ring is provided with a guide surface, the other surface of the guide ring is an inner side surface, the guide ring is equipped with ribs, the guide ring is assembled in a gap arranged behind the rear edges of blades arranged on the circumference of the hub of the impeller to form the impeller assembly, and the ribs are located at an air outlet end of a wind guide groove arranged between two blades, according to this design, ribs, particularly the ribs with wing-shaped cross sections decrease air flow resistance, pressure of blown out air is increased, thereby the flow field is smoothed to save energy, and when the guide ring has more than one , the ribs are connected to support inner guide rings and outer guide rings, which obtains the practical efficiency of simplifying operation.

Description

Impeller sets

Technical field

The invention relates to a kind of combination type blade wheel group, it is provided with rib on the guide ring of impeller, can simplify operation to increase smooth and easy flow field of blast and tool connection guide ring.

Background technique

The impeller sets 200 of existing a kind of tool guide ring 25 cooperates referring to shown in Fig. 7,8,9, and the impeller sets 200 of this kind tool guide ring comprises:

At least one guide ring 25, it is arranged in the breach 24 of blade 21 trailing edge air opening ends, guide ring 25 is ring structurees, when having an above guide ring 25, be interior guide ring 25 near wheel hub, then be outer guide ring 25 away from wheel hub, guide ring 25 outer periphery tool guide faces 26, its another side is an inner side surface, and guide face 26 is a hypotenuse type or streamlined, and establishes the usefulness that flange 27 is thought the location in guide ring 25 air opening end inboards;

Impeller 20, tool one wheel hub 22, and be located on several pieces blades 21 of wheel hub 22 peripheries, 21 in blade 21 and blade are air guide channels 23, and breach 24 default at blade 21 trailing edges and guide ring 25 identical cross-sectional shapes and number.After again guide ring 25 is arranged at this breach 24, block wheel hub 22 root edges by flange 27 and do the location to form impeller sets 200.Though this kind impeller sets 200 blast are bigger, the air that its blade 21 is introduced blows out via air guide channel 23 and guide ring 25 squeezing actions again, get to treat heat-dissipating thing partly air can rebound back in the air guide channel 23 or easily be stranded between exhaust outlet.Please cooperate referring to shown in Figure 10, when being provided with for a plurality of guide rings 25, comparatively complicated and location is difficult for during the also more and scattered assembling of part.

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, and enhances productivity and be the important topic that industry desires to overcome solution.

Summary of the invention

Because the shortcoming of the impeller sets of existing tool guide ring, the technical problem to be solved in the present invention provides a kind of impeller sets, it utilizes and rib to be set on guide ring to increase the pressure of air-flow that impeller sets blows out and smooth and easy flow field with energy-conservation, the operation when simplification is provided with a plurality of guide ring.

For solving the problems of the technologies described above, the present invention proposes a kind of " impeller sets ", it comprises:

One impeller, and at least one guide ring combine, guide ring is a ring structure, its periphery outside tool guide face, another side is an inner side surface, guide face can be hypotenuse type or streamlined, inner side surface also can be hypotenuse type, streamlined or vertical-type, and the guide face at guide ring is established rib, the section of this rib can be the geometric modeling that airfoil, circle, rectangle, triangle or other tool connect supporting effect, when being more than one guide ring, be connected with rib between interior guide ring and outer guide ring, also can be simultaneously outside the guide face of guide ring be provided with wing leaf;

Impeller, tool one wheel hub, and be located on several pieces blades of wheel hub periphery, and establish and guide ring sectional shape and the same number of breach at this trailing edge.Guide ring is arranged in the default breach of trailing edge and forms impeller sets, and rib then is positioned at the air opening end of air guide channel between two blades.

The advantage of structural design has thus, guide ring and outer guide ring in rib connects, and can simplify the program of making and assembling, thus reach the purpose that saves time; Utilize rib to support, make assembling easy and quick in the outer guide ring locating blade breach; Reach the resistance that more can lower air-flow with the airfoil cross section when rib, and increase the pressure of blow out air and smooth and easy flow field with energy-conservation, so get to when air and to treat that heat-dissipating thing is difficult for rebound back in the air guide channel or between the delay exhaust outlet, the present invention truly has the practical effect that can improve radiating efficiency and simplification operation.
