Abstract
A serial radial fan modular set is used for increasing cold air volume with uniform air density and little noise. It consists of a first fan unit and a second fan unit combined together. The first fan unit is located at the inlet side and the second one located at the outlet. A side opening, at least, is arranged on the wall near the connecting portion of the frames of the both fan units to increase air volume.
Description
Technical field
The invention belongs to sink, particularly a kind of heat-dissipating fan series mould set.
Background technique
As shown in Figure 1 and Figure 2, the heat-dissipating fan series mould set of commonly using comprises first fan unit 10 and second fan unit 20, and its mutual tandem compound is to form intake grill and exhaust outlet.
First and second framework 100,200 of first and second fan unit 10,20 utilizes conjunction 11,21 closely first and second fan unit 10,20 to be combined into series mould set.So, second impeller 22 of first impeller of first fan unit 10 and second fan unit 20 can be in order to the synchronous drive air-flow, so that air-flow can be blowed to the exhaust outlet of air side apace by inlet air side intake grill under the driving of first and second impeller.
Though the heat-dissipating fan series mould set of commonly using can be in order to increase wind dispelling amount and air-flow velocity, still there is following shortcoming in it:
1, under first and second fan unit 10,20 runs well, cooling blast only can be sucked by the single intake grill of first fan unit 10 of inlet air side, so that total air output of radiation fan series mould set is restricted.
2, when first fan unit 10 or the running of second fan unit 20 were unusual, the blade rotational speed of first impeller 10 or second impeller 20 was crossed the low wind dispelling efficient that will reduce by second impeller 20 or first impeller 10, thereby influences integral heat sink efficient.
3, when first fan unit 10 or the running of second fan unit 20 are unusual, because the flow velocity difference at first impeller, 10 places and second impeller, 20 places, produce the current density uneven phenomenon, thereby the static pressure/flow speed characteristic (static pressure-flow rate characteristic, P-Q characteristic) that causes the heat-dissipating fan series mould set is low and produce a large amount of wind and cut noise.
Summary of the invention
The purpose of this invention is to provide a kind ofly increase total turnover air quantity, improve integral heat sink efficient, make current density evenly, reduce the heat-dissipating fan series mould set of wind cutting noise.
The present invention it comprise first fan unit and with the first fan unit series combination all-in-one-piece, second fan unit; First fan unit is positioned at the inlet air side, and is provided with first framework and is located in the first interior impeller of first framework; Second fan unit is positioned at the air side, and is provided with second framework and is located in the second interior impeller of second framework; First and second framework of first and second fan unit of series connection all-in-one-piece is provided with at least one crosswind mouth so as to relative increase air output and air output near the wall of junction plane.
Wherein:
Crosswind mouth system is located at first fan unit, first framework near on the wall of air side.
Crosswind mouth system is located at second fan unit, second framework near on the wall of inlet side.
Connect between first fan unit and second fan unit and be provided with the three fan unit of the 3rd framework and the 3rd impeller more than one; The 3rd framework wall is provided with the crosswind mouth.
The 3rd framework wall is provided with at least one crosswind mouth near the air side wall.
The 3rd framework wall is provided with at least one crosswind mouth near the inlet side wall.
The crosswind mouth is rectangular.
The crosswind mouth is rounded.
The crosswind mouth is an ovalize.
The inclination angle of ovalize crosswind mouth major axis becomes positive correlation with the first impeller blade tilt.
The inclination angle of ovalize crosswind mouth major axis becomes positive correlation with the second impeller blade tilt.
The first fan unit air side, the second fan unit inlet air side are provided with the flow-guiding stator blade so as to air-guiding and increase blast.
Since the present invention it comprise first fan unit and with the first fan unit series combination all-in-one-piece, second fan unit; First fan unit is positioned at the inlet air side, and is provided with first framework and is located in the first interior impeller of first framework; Second fan unit is positioned at the air side, and is provided with second framework and is located in the second interior impeller of second framework; First and second framework of first and second fan unit of series connection all-in-one-piece is provided with at least one crosswind mouth so as to relative increase air output and air output near the wall of junction plane.Crosswind mouth system can make the air-flow path of first and second fan unit inside be connected with the outside, and its mutual tandem compound is to form intake grill and exhaust outlet.Whereby, when first and second fan unit normally moved commentaries on classics, the crosswind mouth can increase air output and air output relatively.Unusual and when making the wind dispelling efficient of first impeller or second impeller low in the running of first fan unit or second fan unit, can replenish air output via the adjustment of crosswind mouth, the uneven zone of the current density of and temporary transient formation inconsistent with the wind dispelling amount of filling up first impeller and second impeller, thereby, can reduce the probability that produces noise relatively by the crosswind mouth; Thereby being had, the present invention increases the effect of air output, minimizing noise and lifting integral heat sink efficient.Not only increase total turnover air quantity, improve integral heat sink efficient, and make current density evenly, reduce the wind cutting noise, thereby reach purpose of the present invention.
