Abstract
The utility model discloses a wind driven generator fairing. The wind driven generator fairing comprises a wind driven generator fairing body, wherein a tail end curve in a shape meeting an air dynamic flow formula is reserved on the edge of the tail part of the fairing body; the tail end curve is in smooth transition with the fairing body of a hub; and the minimum cross-sectional area of a clearance between the tail end curve and the hub is greater than or equal to the cross-sectional area of an open hole of an air cooling channel. The wind driven generator fairing has high air exhaust efficiency and a good radiating effect.
Description
Technical field
The utility model relates to a kind of wind-driven generator cowling.
Background technique
In the wind power generating set, some heater elements in wind power generating motor and the wheel hub can cause the wind-driven generator unit to produce very big heat when operation.The part heat distributes in order to incite somebody to action wherein, and present way is divided into 2 kinds usually: a kind of is to adopt the ventilation duct device that heat is discharged from the tower tube; Another kind is to open an aperture at the hub of wind power generator top, by the gap of this aperture and cowling and wheel hub, heat is discharged.The method for exhausting of a kind of mode in back can form eddy current at wheel hub and cowling gap location, hinders effective discharge of heat.
The model utility content
The purpose of this utility model is to provide a kind of exhaust efficiency height, the wind-driven generator cowling of good heat dissipation effect.
The purpose of this utility model is achieved through the following technical solutions: it comprises
Wind-driven generator cowling body, the tail edge of described cowling body is provided with the tail end curve of the mobile formula of shape aerodynamic, described tail end curve and wheel hub cowling body smooth transition, the minimum sectional area in gap is more than or equal to the sectional area in air-cooled access portal hole between tail end curve and the wheel hub.
Described tail end length of a curve L is preferably 10mm to 100mm; Specifically can determine according to the wheel hub installation dimension.
Described tail end curve can be curve or quadratic curve; Preferred multistage curve is as Vickers curve (i.e. six rank curves).
The utlity model has following advantage: owing to set up the tail end curve of the mobile formula of a strip aerodynamic at the tail edge of wind-driven generator cowling, not only simple in structure, and because this tail end curve and wheel hub cowling body smooth transition, hot-fluid can be along the outside water conservancy diversion of curve, can not make flowing gas stop the formation eddy current at wheel hub and cowling gap location, thereby the exhaust efficiency height, good heat dissipation effect.
Description of drawings
Fig. 1 is the utility model one embodiment's an increase fragment position schematic representation;
Fig. 2 is the sectional view at A-A embodiment illustrated in fig. 1 place;
Fig. 3 is the B place partial enlarged drawing of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Embodiment 1
With reference to accompanying drawing 1-3, present embodiment comprises
Wind-driven generator cowling body 1, the edge of described cowling body 1 afterbody is provided with tail end curve 4, tail end curve 4 is Integratively formed with cowling body 1, tail end curve 4 and wheel hub cowling body 1 smooth transition, the minimum sectional area in the gap 5 between tail end curve 4 and the wheel hub 2 equals the sectional area in air-cooled access portal hole 3; Described tail end curve 4 is a curve, and the length of tail end curve 4 is 80mm; The thickness of tail end curve 4 equates with the thickness of cowling body 1.
Owing to set up the mobile formula tail end curve 4 of a strip aerodynamic at the tail edge of cowling body 1, not only simple in structure, and because this tail end curve 4 and cowling body 1 smooth transition, hot air can not make collision formation eddy current between flowing gas and the ambient atmos along tail end curve 4 outside water conservancy diversion.
Embodiment 3
More than be three kinds of mode of executions of the present utility model, three preferred demonstration example.The scope that the utility model please be asked for protection has more than and is limited to described mode of execution.Can also be other multistage curve as the tail end curve, all and technological scheme present embodiment equivalence all belongs to protection domain of the present utility model.
