Abstract
The utility model discloses a big fan flabellum of wing based on it is streamlined, including the flabellum body, the front portion of flabellum body is equipped with the flabellum leading edge, the rear portion of flabellum body is equipped with the flabellum trailing edge, this internally is equipped with a plurality of strengthening ribs the flabellum, and the strengthening rib is transversely arranged in proper order and is had a perfect understanding the flabellum body along the axis, the flabellum trailing edge is the form that has a downwarp. The utility model discloses based on streamlined design, it has at the fan in operation that the amount of wind is big, light in weight, intensity is high, rigidity is good, corrosion -resistant, the easy clean characteristic of maintaining.
Description
Technical field
The utility model relates to a kind of flabellum, and particularly one is based on fairshaped wing big fan flabellum.
Background technique
The aeration-cooling equipment mainly all kinds of air-conditioning of current application, various medium and small fan, and adopt central air-conditioner in slightly large place, or adopt many medium and small fan for cooling.But in the spaces such as tall and big, broad, closed factory building, the effect of this ventilation just exists a lot of not enough.Particularly spring and autumn, temperature, usually between 20 ~ 34 DEG C, is opened and does not turn on the aircondition and will be entangled with very much.And air-conditioning temperature-reducing instantaneity is poor, energy consumption is also large.Because conventional fan flabellum is little, thus rotating speed generally needs very large, but the scope that wind covers is still very limited, and the wind that high speed fan produces directly to blow human body sensory very uncomfortable, Long-Time Service can bring a lot of health problem.There is a lot of deficiencies in existing ventilation, cooling system designing technique.
Model utility content
The purpose of this utility model is to provide that a kind of air quantity is large, lightweight, intensity is high, good rigidity, maintenance corrosion-resistant, easy to clean based on fairshaped wing big fan flabellum.
The utility model is for solving the problems of the technologies described above, provide a kind of based on fairshaped wing big fan flabellum, comprise flabellum body, the front portion of described flabellum body is provided with flabellum leading edge, the rear portion of described flabellum body is provided with flabellum trailing edge, be provided with some stiffening ribs in described flabellum body, stiffening rib is laterally arranged in flabellum body successively, and stiffening rib is connected with the internal surface of flabellum body and along the through flabellum body of axis; Flabellum trailing edge is in the shape that has a downwarp.
Further, the quantity of described stiffening rib is three.
Further, described some stiffening ribs in being arranged in parallel, slightly by leading edge.
Further, the surface of described flabellum body is provided with fluorine oxide carbon-coating.
The utility model achieves following technique effect: can produce larger air quantity in slow-revving situation, has the functions such as nature three-dimensional gentle breeze, dehumidifying, dehumidifying, cooling, reduction energy consumption; Effective weight reduction, makes whole plug-in unit reliably be connected with flabellum; Cryogenic treatment is forged, the process of surface oxidising fluorocarbon baking varnish, wing blade flabellum, and flabellum laterally designs exclusive three stiffening ribs successively, along the through flabellum of axis, effectively prevents the bending of flabellum to be out of shape; Flabellum leading edge both proof strengths, avoid again increasing unnecessary weight, reduce resistance simultaneously as far as possible; Flabellum trailing edge becomes to have a downwarp by streamlined principle design, can form exclusive field of wind-force after running, reach coverage area large, ventilate, good effect of lowering the temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model based on fairshaped wing big fan flabellum.
Embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, below in conjunction with the drawings and the specific embodiments, the utility model being described in further detail.
As shown in Figure 1, a kind of based on fairshaped wing big fan flabellum, comprise flabellum body, the front portion of described flabellum body is provided with flabellum leading edge 1, the rear portion of described flabellum body is provided with flabellum trailing edge 3, be provided with some stiffening ribs 2 in described flabellum body, stiffening rib 2 is laterally arranged successively, and stiffening rib 2 is connected with the internal surface of flabellum body and along the through flabellum body of axis; Flabellum trailing edge 3 is in the shape that has a downwarp; The quantity of stiffening rib 2 is three, and some stiffening ribs 2 are in being arranged in parallel, and the surface of described flabellum body is provided with fluorine oxide carbon-coating.
The utility model wing big fan flabellum, this flabellum adopts aviation magnalium, and cryogenic treatment is forged, the process of surface oxidising fluorocarbon baking varnish, wing blade flabellum; Long 3.5 meters, wide 24 centimetres, high 2.4 centimetres of flabellum, establishes three exclusive stiffening ribs, effectively prevents the bending of flabellum to be out of shape in this flabellum; Fan running can make space form the airflow field of motion and circulation, produces the effect that nature gentle breeze plays personnel's cooling; When this flabellum is connected with outer clip-type connector assembly, with fastening screw along short transverse through connecting, to increase resistance to flexure, thoroughly prevent various unexpected generation; This flabellum is connected with the chassis be fixed on motor shaft by outer clip-type plug connector, chassis has 5 and rises as high as the banks, and radially respectively opens 2 holes, for connecting with outer clip-type plug connector; Described outer clip-type plug connector adopts the high strength alloy Steel material that fatigue resistance is strong, is designed to exclusive outer clip-type casting, milling part, whole plug-in unit and flabellum is combined as a whole, makes overall uniform force; This flabellum hood is the nonmetallic material seal closure installed in flabellum outer end, when power plant drive flabellum running, air can form turbulent flow at the end of streamlined flabellum, and after hood has been installed, eliminate this part energy loss, reduce the noise therefore produced, stablize fan running, make the flowing of air more meet fluid mechanics principle, and bring certain benefit.
The utility model wing big fan flabellum, apply aerodynamics airflow design technology: the rule that flabellum flows according to fluid, be designed to unique sectional shape, contribute under very little rotating speed, form super area coverage solid, even, natural gentle breeze, improve the comfort level of personnel.Have employed Intensity Design technology, new material technology, electric spraying technology, forging manufacturing technique etc.Make flabellum meet the requirement of fan overall design, achieve the low and air quantity of rotation speed of the fan large, fan blade size is large, intensity is high, and weight is relatively light, and good rigidity, low, corrosion-resistant, the easy to clean maintenance of energy consumption effect.Meet place to ventilate, lower the temperature, and the needs of staff's comfort level, be of value to and increase work efficiency.
