Abstract

The utility model relates to an improved efficient forced air cooling radiator which is composed of a casing, a radiator and a fan. The angle between a radiating fin at the air inlet of the radiator and a bottom plate is 45 degrees. According to the utility model, the wind resistance of the radiating fin is small; the radiating efficiency is improved; and wind noise is obviously improved.

Description

A kind of improved efficient forced air cooling radiator

Technical field

The utility model relates to the forced air cooling radiator in a kind of radiator field, particularly relates to a kind of improved efficient forced air cooling radiator.

Background technology

The simple heat radiation form that the high performance components that now needs is dispelled the heat generally uses has, and installs the radiator natural heat dissipation additional, or adopts two kinds of forms of forced air cooling heat radiation.Wherein, the natural heat dissipation form, as long as the efficiently radiates heat area that radiator has can meet the dissipation power that the components and parts needs dissipate, just can ensure the stable operation of components and parts.And the form of forced air cooling heat radiation is in the situation that the radiator natural heat dissipation, can not meet the quick heat radiating of components and parts dissipation power, just need to install the heat radiation of blower fan forced air cooling additional, this heat radiation form can dissipate the heat of radiator fast, improves radiating efficiency.But also there are the following problems for the heat radiation form of this forced air cooling, when blower fan directly blows the fin of radiator, if the distance of blower fan and fin is very near, fin perpendicular to wind direction can produce very large windage, the more windy resistance of fin is larger, directly affect radiating efficiency, noise also can increase simultaneously.As shown in Figure 1.

Because the defect that above-mentioned existing forced air cooling radiator exists, the design people, based on being engaged in this type of product design manufacturing abundant practical experience and professional knowledge for many years, improves existing forced air cooling radiator, and it is had practical value.

Summary of the invention

The purpose of this utility model is, overcome the defect that existing forced air cooling radiator exists, and provide a kind of a kind of improved efficient forced air cooling radiator of new structure, technical problem to be solved is to make its fin windage little, radiating efficiency improves, noise is little simultaneously, thereby more is suitable for practicality.

The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.A kind of improved efficient forced air cooling radiator according to the utility model proposes, be comprised of shell, radiator and blower fan.The fin at this radiator air intake place and the angle of base plate are 45 °.

The utility model compared with prior art has obvious advantage and beneficial effect.By technique scheme, the improved efficient forced air cooling radiator of the utility model, can reach suitable technological progress and practicality, and have the extensive value on industry, and it has following advantages at least:

1. the utility model, owing to fin is become 45 degree with the angle of base plate, makes its fin windage little, thereby has improved radiating efficiency.

2, the utility model is owing to becoming fin 45 degree with the angle of base plate, and wind is made an uproar and significantly improved.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, and for above and other purpose of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and the cooperation accompanying drawing, be described in detail as follows.

Embodiment

Be to reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, its embodiment, structure, feature and effect thereof to according to the utility model proposes, be described in detail as follows.

Shown in please refer to the drawing 2, a kind of improved efficient forced air cooling radiator of the utility model preferred embodiment, it mainly is comprised of shell 3, radiator 2 and blower fan 1, and the fin at the air intake place of described radiator 2 and the angle of base plate are 45 °.The wind that blows of blower fan can directly not blocked by fin like this, but along fin, continues forward.Radiator after improvement is under identical applied environment, and than the low 1-2 ℃ of not improved spreader surface temperature, and wind is made an uproar obvious improvement has also been arranged through actual test.

If change the angle of fin and base plate into 80 °, as shown in Figure 3, obviously do not improve through the test radiating effect, if change the angle of fin and base plate into 30 °, as shown in Figure 4, although on structure, lengthen air channel, reduced windage, but because the angle of fin and base plate is too little, the area of dissipation of whole radiator has also been reduced, affected on the contrary the radiating efficiency of system.In the situation that radiating condition is identical, the size of radiator efficiently radiates heat area directly affects the height of radiating efficiency, and the efficiently radiates heat area is more, and radiating efficiency is higher, otherwise less.Therefore, in the present embodiment, the angle of the fin at the air intake place of radiator 2 and base plate is 45 °, and best results can make its fin windage little, and radiating efficiency improves, and noise is little simultaneously.

the above, it is only preferred embodiment of the present utility model, not the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.

Claims (1)

1. an improved efficient forced air cooling radiator, be comprised of shell (3), radiator (2) and blower fan (1), it is characterized in that: the fin at the air intake place of described radiator (2) and the angle of base plate are 45 °.
