Abstract
The utility model provides a dual-airflow guide type axial flow fan high in air draft and supply efficiency. The dual-airflow guide type axial flow fan comprises a motor, blades, an inner air barrel, guide edge sheets and rotation prevention guide edge strips, the guide edge sheets are arranged on the blades, the rotation prevention guide edge strips are arranged on the wall of the inner air barrel, and the blades are connected with the motor and mounted inside the inner air barrel. The guide edge sheets are added to the blades, the sides, with the guide edge sheets, of the blades are slightly inclined towards the center, and airflow is prevented from flowing in the radial direction under pushing of the guide edge sheets; the rotation prevention guide edge strips are added to the wall of the inner air barrel, the airflow in the barrel is prevented from rotating, meanwhile, the rotating airflow in the barrel is guided into forward axial flow, and therefore axial air supply efficiency is improved; radial flow division of air is limited, fan efficiency can be improved without changing a designed barrel-shaped cavity of an original fan, and the problems that due to the design of a special-shaped cavity, manufacturing difficulty is large, and mounting acting space is limited are solved.
Description
Technical field
The utility model relates to Fan Equipment field, relates in particular to a kind of dual stream guiding type axial-flow blower.
Background technique
Axial-flow blower is mainly used in metallurgy, chemical industry, light industry, the use of the place ventilations such as food or reinforcement heat radiation, be particularly useful for air conditioner outdoor machine, it is easy for installation, ventilation successful, when axial-flow blower operation, air-flow is from axially entering the impeller of blower fan, on barrel surface, flow along axial direction approx, impeller is when promotion air does axial flow, also make the skew of air radial rotary, while also can make the air in stirring have the trend of Radial Flow under the effect of centrifugal force and blade face thrust, due to the radially impact of shunting, what make axial fan pumps wind Efficiency Decreasing, also there is at present a kind of conical tube type blower fan, it can increase accordingly pumps wind efficiency, but with respect to cylindrical chamber, the making of special-shaped cavity is very complicated, and this special-shaped cavity blower fan technology is ripe not enough, when blower fan should not be made special shape tube formula as used times such as air-conditioning outer machine.
Summary of the invention
According to above technical problem, the utility model provides a kind of dual stream guiding type axial-flow blower that wind efficiency is high of pumping, comprise motor, fan blade, interior air duct, it is characterized in that: also comprise guiding rib sheet, hinder and revolve guiding rib, described fan blade is provided with guiding rib sheet, described interior air duct barrel is provided with resistance and revolves guiding rib, and described fan blade is connected with motor, and described fan blade is arranged on the inside of interior air duct.
Described guiding rib sheet has N, N >=1.
Described guiding rib sheet is one-sided to centroclinal setting according to air current flow direction.
It is edge strip shape that guiding rib is revolved in described resistance, according to the curved setting of flow rotation direction.
The beneficial effects of the utility model are: the utility model improves on original basis, on fan blade, increased guiding rib sheet, and the side that guiding rib sheet is set is a little to centroclinal, under the promotion of guiding rib sheet, stop air-flow Radial Flow, guiding rib sheet also has centripetal leading role in axial flow direction, balance the centrifugal trend of air-flow; On interior air duct barrel, increase resistance and revolved guiding rib, stoped the flow rotation in cylinder, the swirling eddy in cylinder has been directed to the axial flow of forward simultaneously, thereby improved axial-feeding-air efficiency; Limited the radially shunting of air, just can improve fan efficiency in the case of not needing to change the cylindrical chamber of original fan design, the design that has solved special-shaped cavity makes the problems such as manufacture difficulty is large, installation action space is limited.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Shown in Fig. 1, the utility model is further described:
As Fig. 1, guiding rib-5 are revolved in motor-1, fan blade-2, guiding rib sheet-3, interior air duct-4, resistance;
The utility model comprises motor 1, fan blade 2, guiding rib sheet 3, interior air duct 4, hinders and revolve guiding rib 5, on fan blade 2, be provided with guiding rib sheet 3, on interior air duct 4 barrels, be provided with resistance and revolve guiding rib 5, when installation, first fan blade 2 is connected with motor 1, then fan blade 2 is arranged on to the inside of interior air duct 4.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection domain of the present utility model.
