Abstract
The utility model relates to an enhanced radiation fan. A fan body forms an axial flow fan and a centrifugal fan, forming an enhanced radiation fan structure by assembly. The utility model mainly makes use of the axial flow fan of a motor hub to absorb air force, the hub is extended with blade cambered surfaces equally outward, large airflow is supplied to a lower centrifugal fan, and the upper end part of the motor hub is provided with a closed circumference. An air-receiving fan carries out the airflow by a centrifugal form to generate the maximum air force to improve the radiation efficiency.
Description
The utility model is relevant for fan, especially about a kind of potent type radiation fan.
Because general radiator fan design, system constitutes with flat cartridge type attitude, outside tube, form flabellum, now because of the restriction of die sinking delivery, so the flabellum of general fan also can't be listed in same axis with flabellum, make two flabellums isolate an intersegmental distance, with regard to mechanics, traditional radiation fan causes the air output of diffusing leaf to improve because of two design problems of structure, and then coefficient of heat transfer can't be promoted always, and following shortcoming is often felt in the design of integral body after the person uses after testing:
First: because traditional fan blade upper end be the plane, so the suction air volume that produced of flabellum rotation can be because no boot media, and the air quantity that makes fan that the upper end air-flow is brought into is quite limited, supplies the wind-force of flabellum release quite little.
Second: since between flabellum and the flabellum apart from quite big, cause air quantity and can't concentrate and take out of, air quantity presents diffusion, so the air quantity of sending is quite not enough, can't reach radiating effect.
Therefore, this creator because present fan in structural design, ubiquity has above-mentioned problem and shortcoming, studied thinking, so develop the utility model it " potent type radiation fan ", uncommon design by the utility model substantially improves the shortcoming of commonly using fan, and the phase is reached following purpose.
The purpose of this utility model is to provide a kind of potent type radiation fan, and it overcomes the limited shortcoming of traditional heat-dissipating body fan suction air volume, it is concentrated take out of, improves radiating effect.
The purpose of this utility model is achieved in that a kind of potent type radiation fan, comprises fan main body, motor, rotating shaft, it is characterized in that described fan main body is divided into the axial fan of upper end and the centrifugal cutter of lower end; This axial fan is outwards divided equally in wheel hub and has been extended the flabellum that several are cambered surface, and each flabellum outside links the motor shell that forms a closed perimeter; The quantity that this centrifugal cutter is provided with flabellum is 2 times of this axial fan flabellum, and the flabellum that is arranged on the axial fan is connected mutually with the pairing flabellum that is arranged on the centrifugal cutter separately.
Above-mentioned potent type radiation fan, it is characterized in that: the wheel hub of described axial fan is that bottom end is arranged with the boss block structure that slotted eye, central authorities are provided with axis hole, and the wheel hub of described centrifugal cutter is that the upper-end surface is provided with the tube structure that the abaculus chimeric with above-mentioned slotted eye, central authorities are provided with axis hole.
The utlity model has following advantage:
1. the axial fan with leading role is adopted in fan main body upper end, and it is big therefore to suck air quantity.
2. the air-flow of importing is concentrated and is sent with centrifugal form, and air quantity can not spread, and has improved air quantity and radiating effect.
3. fan main body is a decomposing type, just to make.
Below lift preferred embodiment now and cooperate graphic being described in detail as follows:
Fig. 1 is the three-dimensional exploded view of the utility model fan main body.
Fig. 2 is the assembled sectional view of the utility model.
Fig. 3 is the airflow analysis figure () of the utility model.
Fig. 4 is the airflow analysis figure (two) of the utility model.
At first, see also illustrated in figures 1 and 2ly, the fan main body of the utility model system is divided into axial fan 1 and 2 liang of parts of centrifugal cutter.Wherein the wheel hub 10 of the axial fan 1 of upper end is the boss block structure, outwards divide equally in wheel hub 10 and to have extended some flabellums 11 that are cambered surface, each flabellum 11 outside links the motor hub 12 that forms a closed perimeter, wheel hub 10 bottom ends are arranged with slotted eye 13, make itself and lower end centrifugal cutter 2 embedding groups, and its central authorities are axis hole 14, wear for rotating shaft 3.The wheel hub 23 of the centrifugal cutter 2 of fan main body lower end is provided with the tube structure of abaculus 21 for the top, has extended some flabellums 20 in outer rim is identical.Flabellum 20 quantity have more one times than the flabellum 11 of upper shaft flow fan 1, and order is and interts the flabellum 20 of position is flabellum 11 corresponding linkings with upper shaft flow fan 1; Cylindrical shell central authorities are axis hole 22, are connected and fixed the fan main body that axial fan 1 and centrifugal cutter 2 constitute the utility model for rotating shaft 3 wears.Outside fan main body, impose coil 4 and motor hub 12 formation motors again; With rotating shaft 3 fan main body is fixedly arranged on the radiator 5, the radiating efficiency and the air quantity of the best is provided.
Please consult Fig. 3 and Fig. 4 again, when flabellum was become to reach rotary driving, the upper end air-flow was rotated suction and axial fan 1 flabellum 11 cambered surfaces of the motor hub 12 of closed perimeter is arranged along the upper end, is directed into centrifugal cutter 2 fully.Owing to the configuration of fan main body system with the upper end partly another flabellum 20 of flabellum 11 and lower end part be and intert same axis arranged side by side and make two parts overlapping, the air-flow of order importing can concentrate on this zone, concentrate again and send with centrifugal form, the unlikely diffusion of air quantity, and then reach the purpose that improves air quantity and radiating efficiency.
In sum, the utility model it " potent type radiation fan " can provide the fan structure of a tool radiating effect, and its effect is very remarkable.
