Abstract

The utility model relates to a centrifugal fan heat radiation module, which mainly comprises a centrifugal fan, which comprises a fan rotor and a fan stator group, wherein the fan rotor is provided with fan blades, and the fan stator group is provided with a shaft core, an upper cover and a frame; a heat sink assembled with the centrifugal fan via the frame of the fan stator assembly; the centrifugal fan is used for generating upward suction force when in operation to suck air quantity, heat radiated from the radiator is quickly discharged, and the heat is discharged to the periphery through the centrifugal fan, so that the air flow with heat is prevented from directly contacting other electronic components, and the heat dissipation effect of the whole heat dissipation module is improved.

Description

The centrifugal fan radiating module

Technical field

The utility model relates to a kind of centrifugal fan radiating module, particularly can promote the centrifugal fan radiating module of the heat radiation function of integral heat sink module.

Background technique

Under the running speed of electrical assembly is accelerated situation with the progress of miniature design, a large amount of heats that the electrical assembly running is produced have become irritating problem, this heat is if can't normally get rid of smoothly, will cause the running of electrical assembly to have some setbacks, even cause working as machine, influence task performance,, often on electrical assembly, add heat extraction assemblies such as a radiator or radiation fan to help the eliminating of heat for effectively getting rid of this heat.

See also Fig. 1 to Fig. 3, traditional radiating module mainly is made up of radiation fan 11 and radiator 12, wherein radiation fan 11 is an axial flow, radiation fan 11 is connected on the radiator 12, and this radiator 12 fitted be mounted on the electrical assembly 13, after radiation fan 11 energising runnings, the distinguished and admirable of this radiation fan 11 blown down to radiator 12 and electrical assembly 13, taking away the heat that is produced on the electrical assembly 13, and electrical assembly 13 conducts to the heat on the radiator 12; But, the radiation fan 11 of this axial flow will conduct to and blow under the heat on the radiator 12 and get rid of, in this case, this heat unavoidably can contact again to electrical assembly 13, and blow mode under this, opposite to the conduction orientation of low temperature with heat by high temperature, so promptly not enough to some extent for the efficient of heat removal.

Summary of the invention

Main purpose of the present utility model provides a kind of fan heat radiation module that can get rid of the heat that is produced when electrical assembly turns round fast.

Centrifugal fan radiating module of the present utility model comprises: a centrifugal fan, comprise a fan propeller and a fan stator group, and have flabellum and axis on this fan propeller, have a core, loam cake and framework on this fan stator group; One radiator has radiating fin, and organizes each other with centrifugal fan via the framework of fan stator group and to establish; The upwards suction that is produced when turning round by centrifugal fan, draw air quantity, get rid of the heat that is given off on the radiator fast, and this heat via centrifugal fan to around get rid of, to avoid having other electrical assembly of distinguished and admirable direct contact of heat, to promote the heat radiation function of integral heat sink module.

The utility model adopts centrifugal fan that heat extraction is upwards got rid of, comply with heat by the conduction orientation of high temperature to low temperature, so the heat that can get rid of on the electrical assembly fast to be produced and electrical assembly conduct to the heat on the radiator, too high with the heat energy of avoiding electrical assembly, cause electrical assembly overall operation usefulness to bring into play fully.

Above-mentioned purpose of the present utility model and structure thereof and functional characteristic will be illustrated according to preferred embodiment shown in the drawings.

Embodiment

The utility model provides a kind of centrifugal fan radiating module.Fig. 4 and Fig. 5 show first embodiment of the present utility model, and it mainly comprises a centrifugal fan 21 and a radiator 22; Wherein centrifugal fan 21 comprises a fan propeller 211 and a fan stator group 212, has flabellum 211a on this fan propeller 211, this flabellum 211a is generally L-shaped, have a core 212a, loam cake 212b and framework 212c on this fan stator group 212, the inboard near upper limb place of this framework 212c is provided with flange 212d, this framework 212c is arbitrary shape for being mounted on can process on the radiator 22, is example in the present embodiment with square.

Fan propeller 211 is articulated on the axle core 212a that is arranged in fan stator group 212, has radiating fin 221 on this radiator 22, and via the framework 212c of fan stator group 212 with centrifugal fan 21 connect each other establish after, this radiator 22 is installed fit on the electrical assembly 23 again.

Please consult Fig. 4 again, axially has a formed space of a height difference between the bottom 211b of the flabellum 211a of this fan propeller 211 and the axis 211c of fan propeller 211, when fan propeller 211 rotates, the characteristic that comparatively protrude at this 211b place, the nearly bottom of flabellum 211a that is the L type of formed viscous flow gas permeable under the axis 211c, and circulated, and reach the rising space that increases heat, promote the effect of heat radiation.

Distinguished and admirable schematic representation when Fig. 6 is the utility model running, the heat that is produced during these electrical assembly 23 runnings is via radiator 22 conduction, and get rid of heat with radiation mode via 221 of radiating fins, when centrifugal fan 21 energising runnings, the upwards suction that is produced during by fan propeller 211 runnings, draw air quantity, and by the characteristic of heat to the conduction of low temperature zone, to quicken to get rid of the heat that is given off on the radiator 22, and this heat is to getting rid of all around via centrifugal fan 21, so that distinguished and admirable can be not directly not the blowing on the electrical assembly arround the electrical assembly 23 that has a heat, to promote the heat radiation function of integral heat sink module.
