Description
Technical field
The present invention relates to technical field of industrial equipment, be specifically related to a kind of low noise fan being applied to the orientation cooling of industry equipment or electronic component.
Background technique
The propagation of sound has distance limit, there is not harmful toxic matter, the feature such as can not to accumulate, and namely sound source disappears and namely stop, so noise pollution can cannot focus on as solid, water, pollution of atmosphere.But noise can affect human central nervous system, digestive system, the organs of vision, also there is various interference to live and work in the various disease such as bring indigestion, vomiting, early stage hearing to become deaf.Noise reducing, the noise of mine ventilator, the noise etc. of server fan of such as space shuttle, these noises are just present in the middle of our daily life, the impact of short time is also not obvious, if but live in these noises for a long time, insomnia can be caused to human body, fatiguability, the multiple body and mind injury such as slow in reacting.
From aircraft equipment, engineering machinery, automobile to daily little medium-sized electronic equipment, radiation fan controls the ambient temperature set, and is the guarantee that each equipment runs well.Along with the function set is gradually become strong, the radiating requirements of radiation fan is also improved constantly.Meanwhile, the noise problem that it brings also is subject to people's attention gradually.Especially in recent years, low noise has become an equipment purchase index.Design low noise fan and research radiation fan noise-reduction method have become the active demand of Consumer and MANUFACTURER.Not only meet radiating requirements but also can ensure that the radiation fan that operational noise is lower is commercially more competitive, each producer also it can be used as the emphasis of research and development in succession.
But the ventilation of the many motors of China, how to adopt disc type (namely centrifugal) fan on motor, noise is relatively large, and is difficult to realize the effective cooling to parts local location.
Summary of the invention
Object of the present invention is in order to overcome the large and inefficient deficiency of cooling of existing fan noise, provide a kind of low noise fan of orientation cooling, it is while effectively reducing fan work noise, directed air blast can be realized, thus reach the object improving cooling efficiency, lay the foundation for improving Industrial fan Structure and Properties further.
To achieve these goals, the technical solution used in the present invention is:
A kind of low noise fan of orientation cooling, comprise the fan frame (1) adopting integral spinning plektron chamber structure, the both sides of fan frame (1) evenly offer some air inducing grooves (5) in the circumferential along its center, and the fluting direction of each air inducing groove (5) and this low noise fan turns direction match, the outlet end of each air inducing groove (5) be opened in the fan frame chamber (6) fanning frame (1) center and be connected; The side of fan frame (1) is provided with drive bearing for connecting motor and linkage rod, its opposite side central position connects ventilation duct (3), be air inducing runner (7) in this ventilation duct (3), the entry end of air inducing runner (7) is connected with the outlet end of fan frame chamber (6); During use, the outlet end of ventilation duct (3) is connected to target cooling-part (4).
The present invention further improves and is: ventilation duct (3) is fillet structure with the interface section (2) of fan frame (1) joint.
Compared with prior art, the invention has the advantages that:
1) adopt fan frame flabellum integrative design, the flabellum that instead of conventional fan to fan frame unitary rotation rotates, and reduces in rotation process due to localized vibration that component mass eccentricity brings;
2) fan surface all adopts airflow design, is treated to by part interface simultaneously and seamlessly transits, reduce the resistance of air in rotation process;
3) chamber design pattern is adopted to substitute traditional open by design pattern, the energy dissipation of flabellum air-supply can be reduced, make air-flow can fully mix in chamber simultaneously, inhibit the generation of air flow swirl, reduce the rotational noise because uneven air-flow produces the effect of fixing original paper;
4) adopt the design of pipeline air inducing, directed air-supply effect can be realized, improve local radiating efficiency, blowing face air-supply blind spot can be eliminated simultaneously.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated
See Fig. 1 to Fig. 4, the low noise fan of a kind of orientation cooling of the present invention, comprise the fan frame 1 adopting integral spinning plektron chamber structure, center along fan frame 1 evenly offers some air inducing grooves 5 in the circumferential, with alternative conventional fan flabellum, and the fluting direction of each air inducing groove 5 and this low noise fan turns direction match; The outlet end of each air inducing groove 5 be opened in the fan frame chamber 6 fanning frame 1 center and be connected; The side of fan frame 1 is provided with drive bearing for connecting motor and linkage rod, electric drive is realized to connect motor, its opposite side central position connects ventilation duct 3, is air inducing runner 7 in this ventilation duct 3, and the entry end of air inducing runner 7 is connected with the outlet end of fan frame chamber 6; During use, the outlet end of ventilation duct 3 is connected to target cooling-part 4, can according to target component size adjusting pipe outlet shape.
Further, the slotted eye size of each air inducing groove 5 and fan delivery adapt.Ventilation duct 3 is fillet structure with the interface section 2 of fan frame 1 joint, to reduce the air drag loss in rotation process, plays the effect of shrink nozzle simultaneously, and being conducive to increases airspeed, improves the cooling effectiveness to object component.
In order to understand further the present invention, now an explanation is done to its working procedure.
In fan work process, fan entirety is rotated with fixed-direction by driven by motor, fan surrounding atmosphere is under the effect of fan external and internal pressure difference, fan frame chamber 6 is inhaled into by fan frame 1 both sides air inducing groove 5, to carry out circular movement relative to rotating contrary turning to fan frame 1 in fan frame cavity 6, during by interface section 2, air-flow is compressed effect, flow velocity rises, and is sent to target cooling element 4 carry out Local cooling along air inducing runner 7.
In fan frame chamber 6, air-flow collides mutually, avoids the generation of flabellum tail whirlpool, reduces due to the uneven noise brought with airflow function; Relative to conventional fan, adopt flabellum fan frame integrative design, add fan intensity, prevent the generation of resonating, eliminate the vibrations noise produced in high speed rotating process due to flabellum strength deficiency; Various noise produces in chamber interior, and sound wave is with after air-flow rotation in fan frame cavity, collision, interaction, and its energy can significantly reduce, and effectively can reduce the influence of noise of fan for external environment condition.
