Embodiment
The present invention provides a kind of side-blow heat radiator, and the particular design of its air intake vent can suppress the adverse current of air-out and increase the air output and the heat dissipation of air outlet.It can be used but be not limited to general centrifugal fan, side-blowing fan and side blown type heat radiation module.The present invention further application note sees also following
Embodiment.
The first embodiment of the present invention is a centrifugal fan or a side-blowing fan.
Consult Fig. 3 and Fig. 4, wherein Fig. 3 is the decomposing schematic representation of the first embodiment of the present invention; Fig. 4 is the schematic perspective view of the first embodiment of the present invention.Side-blowing fan of the present invention comprises a fan frame 100 and a blade structure 200.Wherein this blade structure 200 is to be formed in this fan groove 130 that frame 100 limited and to form the runner of an air-flow.This runner be meant gas by air intake vent to air outlet the path of process.The shape of this blade structure 200 and indefinite, this blade structure 200 is to be a centrifugal blade structure in this embodiment, comprises a wheel hub 210, a base plate 220 and a plurality of blade 230 that is formed on the base plate.The axial charge air flow that this blade 230 will be parallel to blade structure 200 be converted to along wheel hub 210 radially away from air-flow after discharge.
Still consult Fig. 3 and Fig. 4, this fan frame 100 also has an air intake vent 110 and an air outlet 120.Or say that this fan frame 100 is made of a pedestal 100a and a loam cake 100b, and this pedestal 100a has an air intake vent 110, and this pedestal I00a has an air outlet 120.It should be noted that the present invention is provided with a baffle plate 150 in the higher-pressure region of runner, and this higher-pressure region is the end that is positioned at runner.That is air intake vent 110 of the present invention is provided with a baffle plate (dotted line partly) 150 and makes air intake vent 110 be part circular with air outlet 120 place's adjoiners.
Because rule of thumb show, in the higher-pressure region of runner, that is in position near the air outlet place, air-flow regular meeting adverse current get back to air intake vent and with charge air flow mutual interference and reduced air output mutually.For this reason, the present invention stops that with this baffle plate 150 this counter-current flow is overflowed by air intake vent 110, increases air output to force more air-flow to be discharged by air outlet.Can learn that according to measurement the present invention has increased more than 20% at least compared to the air output of unidimensional known side-blowing fan (air intake vent is for circular).So can reach same air output by lower rotating speed, so promptly reduce noise.
Of the present invention high-effect for illustrating, compare with a side-blowing fan of the present invention and a known side-blowing fan, can descend the parameter of tabulation one.
Table one
| The present invention | Known | |
| Rotating speed (rpm) | 4000 | 4000 |
| Maximum stream flow (CMM) | 0.154 | 0.125 |
Can inference according to this table one, when known fan was wished to get same maximum stream flow Qmax, its rotating speed must be promoted to 4900rpm approximately.Therefore, the present invention can obtain a higher air output with lower rotating speed.
The second embodiment of the present invention is the side blown type heat radiation module that comprises the blade structure of naked fan for.See also Fig. 5, this figure is the decomposing schematic representation of the second embodiment of the present invention.This side blown type heat radiation module is to be provided with in abutting connection with a desire heat abstractor, and for example this side blown type heat radiation module is the side that is arranged at a central processing unit (not shown).As shown in the figure, the second embodiment of the present invention comprises a housing 100 and a blade structure 200.Wherein, this housing 100 has an air outlet 120 and a part is circular air intake vent 110, and this housing 100 optionally has a loam cake 100b, and the material of this housing 100 can be metal in this embodiment, for example aluminum or aluminum alloy etc.
Consult Fig. 5, the shape of this blade structure 200 and indefinite, for example an axial-flow type blade structure, centrifugal blade structure or a side blown type blade structure.This blade structure 200 is to be a centrifugal flabellum in this embodiment, and it comprises a wheel hub 210, a base plate 220 and a plurality of blade 230 that is formed on the base plate 220.Wherein this blade structure 200 is to be formed in this fan groove 130 that frame 100 limited and to form the runner of an air-flow.This runner is meant that gas is by the path of air intake vent 110 to 120 processes of air outlet.The axial charge air flow that this blade 230 will be parallel to blade structure 200 be converted to along wheel hub 210 radially away from air-flow after discharge.
Still consult Fig. 5, with first embodiment similarly be, second embodiment also is provided with a baffle plate 150 in the higher-pressure region of runner, and this higher-pressure region is the end that is positioned at runner.That is the adjoiner of air intake vent 110 of the present invention and air outlet 120 is provided with a baffle plate (dotted line partly) 150 and make air intake vent 110 parts for circular, this baffle plate 150 can stop that counter-current flow is overflowed by air intake vent 110, increases air output to force more air-flow to be discharged by air outlet 120.
Still consult Fig. 5, this side blown type heat radiation module has more a heat-conducting plate 500, it is to extend the platform of desiring heat abstractor in order to carrying for a sidewall by housing 100, for example the desire heat abstractor of central processing unit can form adjacency with the side blown type module that dispels the heat after placed on it, and this heat-conducting plate 500 can absorb the heat energy of desiring heat abstractor.In addition, the air outlet 110 of this side blown type heat radiation module more is provided with a plurality of radiating fins 160, and the material of this radiating fin 160 can be metal in this embodiment, for example aluminum or aluminum alloy etc.The heat-conducting plate 500 of this side blown type heat radiation module has more a heat pipe 170, and it is adjacent to desire heat abstractor (not shown) and is provided with, and extends to radiating fin 160 by heat-conducting plate 500.This heat pipe 170 is to guide to radiating fin 160 in order to the heat energy that will desire heat-conducting plate 500, so can nationality makes the heat energy dissipation of desiring heat abstractor by brushing of air-flow that blade structure 200 drove.
The above is preferred embodiment of the present invention only, is not in order to limit claim of the present invention; All other do not break away from the equivalence of being finished under the disclosed spirit and changes or modification, all should be included in the following claim.
