Description
Technical field
The present invention relates to technical field of industrial equipment, be specifically related to a kind of orientation cooling being applied to industrial equipment or electronic component
Low noise fan.
Background technology
The propagation of sound has distance limit, there is not harmful toxic matter, the feature such as will not accumulate, and sound source i.e. disappears and i.e. stops,
So sound pollution can cannot focus on as solid, water, atmospheric pollution.But noise can affect human central nervous
System, digestive system, visual organ, bring dyspepsia, vomiting, in early days audition the various diseases such as to become deaf, to life and work
There is also various interference.Noise reducing, the noise of mine ventilator, the noise etc. of server fan of such as space shuttle, this
A little noises are present in the middle of our daily life, and the impact of short time is the most inconspicuous, if but live in these noises for a long time,
Human body can be caused the multiple body and mind injuries such as insomnia, fatiguability, bradykinesia.
From aircraft equipment, engineering machinery, automobile to daily little medium-sized electronic equipment, radiator fan controls the ambient temperature set,
It it is the guarantee of each equipment normal operation.Along with the function set is gradually become strong, the radiating requirements of radiator fan is also improved constantly.
Meanwhile, the noise problem that it is brought the most gradually is subject to people's attention.The most in recent years, low noise has become one
Equipment purchase index.Design low noise fan and research radiator fan noise-reduction method have become the urgent needs of consumer and manufacturer.
Not only having met radiating requirements but also can guarantee that the relatively low radiator fan of work noise is the most more competitive, each producer is the most in succession by it
Emphasis as research and development.
But, the ventilation of China's many motors, how on motor, to use disc type (the most centrifugal) fan, noise is relatively large,
And it is difficult to the effective cooling to parts local location.
Summary of the invention
The purpose of the present invention is in order to overcome existing fan noise big and inefficient deficiency of lowering the temperature, it is provided that a kind of orient the low of cooling
Noise fan, it is while effectively reducing fan work noise, it is possible to realizes orientation air blast, thus reaches to improve cooling efficiency
Purpose, lay the foundation with performance for improving Industrial fan structure further.
To achieve these goals, the technical solution used in the present invention is:
A kind of low noise fan orienting cooling, including the fan frame (1) of employing integral spinning plektron chamber structure, fan frame (1)
Both sides the most uniformly offer some air inducing grooves (5) along its center, and the fluting direction of each air inducing groove (5) and this low noise
Sound fan rotation direction matches, the port of export of each air inducing groove (5) and the fan frame chamber (6) being opened in fan frame (1) center
It is connected;The side of fan frame (1) is provided with the drive bearing for connecting motor and gangbar, and its opposite side center connects
Ventilation duct (3), is air inducing runner (7) in this ventilation duct (3), the arrival end of air inducing runner (7) and fan frame chamber (6)
The port of export is connected;During use, the port of export of ventilation duct (3) is connected to target cooling-part (4).
The present invention is further improved by: ventilation duct (3) is fillet structure with the interface section (2) of fan frame (1) junction.
Compared with prior art, it is an advantage of the current invention that:
1) using fan frame flabellum integrative design, the flabellum that instead of conventional fan with fan frame unitary rotation rotates, and reduces rotation
During the local vibration that brings due to parts mass eccentricity;
2) fan surface all uses airflow design, is processed as seamlessly transitting by part interface simultaneously, reduces in rotation process
Air drag;
3) chamber design pattern is used to substitute traditional open by design pattern, it is possible to reduce the energy dissipation of flabellum air-supply, simultaneously
Air-flow can be sufficiently mixed in chamber, it is suppressed that the generation of air flow swirl, reduce owing to uneven air-flow is to fixing original paper
Effect and the rotational noise that produces;
4) use the design of pipeline air inducing, it is possible to realize orientation air-supply effect, improve local radiating efficiency, can eliminate simultaneously and blow
Wind face air-supply blind spot.

Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings
Seeing Fig. 1 to Fig. 4, a kind of low noise fan orienting cooling of the present invention, including using integral spinning plektron chamber structure
Fan frame 1, the center along fan frame 1 the most uniformly offers some air inducing grooves 5, to substitute conventional fan flabellum, and each draws
The fluting direction of wind groove 5 matches with this low noise fan rotation direction;The port of export of each air inducing groove 5 be opened in fan frame 1
The fan frame chamber 6 at center is connected;The side of fan frame 1 is provided with the drive bearing for connecting motor and gangbar, to connect
Motor realizes driven by power, and its opposite side center connects ventilation duct 3, is air inducing runner 7 in this ventilation duct 3, air inducing runner
The arrival end of 7 is connected with the port of export of fan frame chamber 6;During use, the port of export of ventilation duct 3 is connected to target cooling-part 4,
Can be according to target component size adjusting pipe outlet shape.
Further, the slotted eye size of each air inducing groove 5 adapts with fan delivery.Ventilation duct 3 and fan frame 1 junction
Interface section 2 is fillet structure, to reduce the air drag loss in rotation process, simultaneously works as the effect of shrink nozzle, favorably
In increasing air velocity, improve the cooling effectiveness to object component.
In order to the present invention is further appreciated that, now its work process is done an explanation.
During fan work, fan entirety is rotated with fixed-direction by driven by motor, and fan surrounding air is inside and outside fan
Under pressure differential effect, it is inhaled into fan frame chamber 6 by fan frame 1 both sides air inducing groove 5, with relative and fan frame 1 in fan frame cavity 6
Rotating contrary turning to and carry out circular motion, during by interface section 2, air-flow is risen by compression, flow velocity, along air inducing stream
Road 7 is sent to target cooling element 4 and is carried out Local cooling.
In fan frame chamber 6, air-flow mutually collides, it is to avoid the generation of flabellum tail whirlpool, reduces due to uneven and air-flow
The noise that effect brings;Relative to conventional fan, use flabellum fan frame integrative design, add fan intensity, prevent resonance
Generation, eliminate the vibrations noise produced during high-speed rotation owing to flabellum intensity is not enough;Various noises are in chamber
Portion produces, sound wave rotates in fan frame cavity with air-flow, collide, interact after, its energy can be greatly lowered, permissible
Effectively reduce the fan influence of noise for external environment condition.
