The working efficiency of the radiating fan and the radiating efficiency of the radiator are improved effectively by the flow guiding function of the arc flow deflector.

Description

Apply to the radiation fan of radiator

Technical field

The utility model is a kind of radiation fan that applies to radiator, refers to a kind of heat sinking fan that can effectively promote fan work efficient especially.

Background technique

By getting rid of the hot radiating requirements of electrical assembly running institute generations height, at present such as many electronic products such as computer, servers, all can install radiator additional, guarantee the electronic product normal and stable operation by the heat dissipation of radiator at the side of chip processor.The kind kenel of radiator is various at present, for example: and frame type radiator, blast-type cooling device or casket type radiator ... wait various kenels, and be applied to different occasions respectively and different heat dissipations is provided.

Figure 4 shows that at present existing a kind of frame type radiator structure, this radiator is provided with one can be in conjunction with the conjunction base 50 that is posted by chip processor, side one at this conjunction base 50 links the middle empty boxes seat 51 that a flat kenel is arranged, the central position of empty boxes seat 51 is combined with a radiation fan 90 in this, and should cooperate these radiation fans 90 to offer an intake grill 52 by middle empty boxes seat 51, simultaneously respectively be provided with a copper radiating fin 54 in air channel 53 outlets that middle empty boxes seat 51 forms, but and be provided with the copper conductor 50 of a quick conductive between this radiating fin 54 and the conjunction base 50; So, radiation fan 90 can suck cool airs by

intake grill

52, and 53 blow through each radiating fin 54 heat is taken away through the air channel, reach the usefulness of quick heat radiating.

Wherein as shown in Figure 5, radiation fan 90 of the prior art is provided with a circular hub 91, this wheel hub 91 is provided with a rotating shaft (not shown in the figures) in order to be incorporated into the motor stator axis hole at shaft core position, and with the outside projection of kenel uniformly-spaced plural pieces flabellum 92 is arranged around this wheel hub 91.Though can having utilized flabellum 92 to produce, existing radiation fan 90 inhales the air-supply effect, it is less but at present to be 92 air quantity that can produce of flabellum of tiltedly establishing kenel merely, produce the phenomenon that refluxes simultaneously easily at intake grill 52 positions, not only limit air quantity efficient and heat dissipation that 90 of radiation fans can provide widely, and can produce tangible wind and cut noise and power consumption height, be studied improved necessity again so have.

The model utility content

Because every scarce fraud and restriction that the radiation fan of aforementioned conventional produces because of the fan blade structure designing institute, the utility model designer development and Design goes out a kind of heat sinking fan structure that applies to radiator.

Main purpose of the present utility model provides and a kind ofly can effectively promote working efficiency and reduce the radiation fan that wind is cut noise, it mainly is to stretch the guide plate that is provided with arc in each flabellum top side towards the sense of rotation one of radiation fan, guide functions by the arc guide plate, can improve air-supply efficient, the reduction wind of radiation fan and cut noise and reduce the consumption electric energy, significantly promote the practicability of radiation fan and the heat dissipation of radiator.

Based on aforementioned purpose, the technological means that the utility model used is to provide a kind of radiation fan that applies to radiator, this radiation fan is provided with a wheel hub, with the outside projection of kenel uniformly-spaced the plural pieces flabellum is arranged around this wheel hub, its main structure characteristics is: each flabellum, is stretched towards each one of sense of rotation of radiation fan and to be provided with a guide plate in abutting connection with an end of this wheel hub at position, stage casing, top side.

Preferable, the guide plate that the utility model is located at each flabellum is the arc lamellar body, and is the outstanding kenel that is higher than described wheel hub end face.

The utility model provides the radiation fan that applies to radiator, and the concrete effect enhancement that can obtain includes:

One, the outstanding arc guide plate of the utility model utilization can produce good air-guiding effect, significantly increases the suction air output that flabellum can produce, and improves the running usefulness of radiation fan.

Two, the guide functions that produced of the outstanding arc guide plate of the utility model utilization, can avoid radiation fan to produce the phenomenon that refluxes, the effective solution has radiation fan forms backflow easily between flabellum top side and intake grill problem now, and the working efficiency, the minimizing that significantly improve radiation fan consume the heat dissipation of electric energy and promotion radiator.

Three, the outstanding arc guide plate of the utility model utilization can reduce the wind of radiation fan and cut noise, promotes the practical usefulness of radiation fan.

Embodiment

Being can detail knowledge technical characteristics of the present utility model and practical effect, further with as the preferred embodiment shown in graphic, is described in detail as follows now:

As shown in Figure 1, 2, the utility model applies to the radiation fan of radiator, this radiation fan 10 is provided with a circular hub 11, this wheel hub 11 is provided with a rotating shaft at shaft core position, utilize this rotating shaft to be inserted into the stator axis hole of the set motor of radiator, by allowing motor can drive radiation fan 10 runnings, this radiation fan 10 has plural pieces flabellum 12 with the outside projection of kenel uniformly-spaced around wheel hub 10, more than be the essential structure kenel of general radiation fan, hold and do not give unnecessary details.

Shown in Fig. 1,3, the main structure characteristics of the utility model is: each flabellum 12 in the stage casing, top side in abutting connection with an end of this wheel hub 10, stretch towards each one of sense of rotation of wheel hub and to be provided with a guide plate 13, each guide plate 13 is for cooperating the curved arc shape lamellar body of flabellum 12 kenels, and each guide plate 13 is the outstanding kenel that is higher than wheel hub 11 end faces, each guide plate 13 can be set as an end high kenel outside interior the hanging down that the other end is increased gradually by abutment bosses 10 simultaneously.

When the utility model was assembled the casket type radiator that applies to shown in Fig. 2,3, this casket type radiator can cooperate guide plate 13 structures of radiation fan 10, was formed with the guide ramp 522 of the oblique reducing shape of awl at the intake grill 52 of middle empty boxes seat 51; So, when radiation fan 10 runnings, can utilize curved and outstanding guide plate 13 to come air-guiding, not only can significantly promote 12 suction air outputs that can produce of flabellum, and can fully solve existing radiation fan and between flabellum top side and intake grill, form the problem that refluxes easily, effectively reduce wind and cut noise and reduce the consumption electric energy, significantly promote the working efficiency of radiation fan and the heat dissipation of radiator.
