Description

Split type sound leaf radiation fan

Technical field

The utility model relates to a kind of split type sound leaf radiation fan, the fan of the design that particularly a kind of sound leaf is split type.

Background technique

General existing axial fan has the axial fan (being the movable vane fan) of single-stage movable vane form and the axial fan (being integral type sound blade fan) of sound leaf two-stage one, provides fluid mobile propelling force by fan sound leaf around the rotation of fan shaft.

Described movable vane fan is owing to be subjected to the restriction of fluid mechanics principle, its flow outlet direction must with the fan axis tilt, so that become the outside diffusion of divergence form mobile when flowing out by exporting, thereby cause fluid to concentrate, airflow direction and radiating fin direction are inconsistent, cause resistance to increase, and flow through the air quantity reduction of radiating fin, radiating effect is not good, and noise increases.

Described integral type sound blade fan is improved at the shortcoming of movable vane fan, add the static blade of one-level in the movable vane back, movable vane and stator blade are shared a fan hollow framework, the air-flow that stator blade can export movable vane divergent shape carries out rectification, make the wind concentration of fan outlet, airflow direction flows to be approximate parallel fan axial direction, and consistent with the radiating fin direction, improves the air quantity and the noise of the radiating fin of flowing through.

Yet described integral type sound blade fan still has many problems on reality is used, because it is the integral type design, can only be at the work down of specific a kind of environment, as will be applied to other environment the time, the actual operating state and the environment that are described fan are not inconsistent, and cause the working condition of fan to worsen, and efficient reduces, flow reduces, and noise increases.Moreover because integral type design, a part instrumentality is not had at described stator blade position and movable vane position, and promptly both must both all change a damage time wherein have no to replace and follow transsexual facility, cause manufacture cost to increase, and it are required not to be inconsistent the user.

After the improvement technology is arranged, fan forced inducer device as No. the 488497th, TaiWan, China patent gazette Announcement Number, and the assembled fan and the employed fan frame structure thereof of No. the 523652nd, TaiWan, China patent gazette Announcement Number, described two cases have all disclosed a common technology, be that described stator blade position and movable vane position are split type, can organize combination more by this and change, not only promote air quantity and blast and can be according to the difference of working environment, and matched combined adapts to described working environment.

Yet above-mentioned technology also has its problem to exist in the use, because split type design, so that widen spacing between movable vane and stator blade, and fluid is when flowing toward stator blade behind the movable vane, because distance widens, so that cause fluid dynamic energy to reduce, moreover split type combination between stator blade and movable vane, both have the gap by mutual combinating face, make segment fluid flow not flow through stator blade as yet promptly from the gap overflow, make stream detract, and then influence the lifting capacity of blast.

So because above-mentioned every shortcoming, the inventor of this case exhausts its intelligence then, to be engaged in described industry experience for many years, concentrate on studies and innovated improvement, successfully the split type sound leaf of this part radiation fan case is finished in research and development finally, is the novel of tool effect enhancement in fact.

Summary of the invention

The purpose of this utility model is to provide a kind of split type sound leaf radiation fan, and movable vane and stator blade are to be indivedual monomers, and described stator blade is to extend to reduce distance between movable vane and stator blade toward the movable vane direction, has the characteristic of saving the space.

In order to achieve the above object, this is novel to provide a kind of split type sound leaf radiation fan, and it comprises that one has the fan of a fan frame, and described fan frame both sides form an import, an outlet, one bearing seat is to be located at close outlet side place in the described fan frame, and a movable vane is rotatable being hubbed on the bearing seat; At least one stator blade fan device, it is the outlet port that is mounted on described fan frame, its tool one hollow framework, in described hollow framework, be provided with a wheel hub, and be provided with a plurality of stator blades between described wheel hub and hollow framework inwall, the wherein arbitrary axial protrusion in the past described fan frame both sides of described stator blade, and extend in the outlet side of above-mentioned fan frame.

The advantage that the utlity model has:

1, the utility model is because stator blade protrudes framework, that is the thickness of framework can be done thinlyyer compared to general prior art, and stator blade is again with in the inlet side that extends into described fan, not only increase the pressure of fluid, and the correction of fluid process stator blade can be similar to the direction that parallels to the axis and flow, make the total thickness of fan and stator blade fan device become thinner simultaneously compared to prior art, reach by stopper and prevent the fluid over-flow impairment, have more the fluid flow that reservation flows into from inlet, and then promote flow.

2, movable vane and stator blade are to be indivedual monomers, and described stator blade is to extend to reduce distance between movable vane and stator blade toward the movable vane direction, have the characteristic of saving the space.

Characteristic on above-mentioned purpose of the present utility model and structure thereof and the function will be illustrated according to appended graphic preferred embodiment.
