Abstract
The utility model relates to an eleven-blade open type cooling fan which comprises an annular hub and a plurality of blades evenly arranged on the periphery of the hub, wherein one side of each blade is convex and the other side of each blade is concave to form an arc shape, a flow deflector is arranged on the convex surface of each blade, and each flow deflector extends outwards gradually and is heightened gradually from one end of the part, connected with the hub correspondingly, of a corresponding blade to the other end of the part, connected with the hub correspondingly, of the corresponding blade. The eleven-blade open type cooling fan is capable of improving cooling efficiency effectively.
Description
Technical field
The utility model relates to the auto parts and components field, is specifically related to a kind of 11 leaf open type cooling fans.
Background technique
Traditional IC. engine cooling fan, usually adopt 11 leaf open types, ten a slice blades that it comprises the wheel hub of circular setting and evenly is arranged on the wheel hub periphery, it is the arcuation setting that projecting surface, opposite side are recessed surface that described blade all is a side, the mobility of its air and poor radiation, thereby reduced the radiating efficiency of internal-combustion engine, the consumed power of motor is increased, so that the working life of having reduced motor.
Summary of the invention
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of 11 leaf open type cooling fans of effective raising heat dispersion.
For achieving the above object, the utility model provides following technological scheme: a kind of 11 leaf open type cooling fans, the ten a slice blades that comprise the wheel hub of circular setting and evenly be arranged on the wheel hub periphery, it is the arcuation setting that projecting surface, opposite side are recessed surface that described blade all is a side, on the projecting surface of described blade, guide plate is set, and an end of described guide plate joint with wheel hub corresponding to blade is corresponding to blade and the outwards extension and increase highly gradually setting gradually of the other end of the joint of wheel hub.
By adopting technique scheme, make the part airflow diversion enter the fan center position, guide vane reduces the central gas stream disorder simultaneously, reduced fan noise, make internal combustion engine operation more steadily promote the absorption of fan center's heat, effectively improved air flow property and the heat dispersion of IC. engine cooling fan, thereby improved the radiating efficiency of internal-combustion engine, improve the consumed power of motor, and then extended the working life of motor.And the interpolation of guide plate design promotes fan blade intensity simultaneously, make its overall structure better rationally reliable, extend the fan work Life cycle, reduce the raw material energy consumption.
The utility model further arranges: the recessed surface of described blade is provided with near the wheel hub position connecting sheet be connected with wheel hub, and described connecting sheet parallels setting with the axial direction of wheel hub.
By adopting technique scheme, when having guaranteed blade strength, reduced overall weight, thereby further reduced the consumed power of motor.
The utility model further arranges: the inboard of described wheel hub is provided with to projecting inward land, described wheel hub correspondence is provided with stiffening rib with the inboard of the joint of blade, the axial section of the corresponding wheel hub of described stiffening rib arranges right-angled triangle, and two right angle sides of stiffening rib are connected with wheel hub and land respectively.
By adopting technique scheme, further, when having guaranteed blade strength, reduced overall weight, thereby further reduced the consumed power of motor.
Below in conjunction with accompanying drawing, the utility model is further described.
The accompanying drawing explanation
Fig. 1 is the utility model example structure figure mono-;
Fig. 2 is the utility model example structure figure bis-.
Embodiment
Referring to accompanying drawing 1 and accompanying drawing 2, the disclosed 11 leaf open type cooling fans of the utility model, the ten a slice blades 2 that comprise the wheel hub 1 of circular setting and evenly be arranged on wheel hub 1 periphery, it is the arcuation setting that projecting surface 201, opposite side are recessed surface 202 that described blade 2 all is a side, on the projecting surface 201 of described blade 2, guide plate 203 is set, and an end of described guide plate 203 joint with wheel hub 1 corresponding to blade 2 is corresponding to blade 2 and the outwards extension and increase highly gradually setting gradually of the other end of the joint of wheel hub 1.By adopting technique scheme, guide plate 203 makes the part airflow diversion enter the fan center position, guide plate 203 reduces the central gas stream disorder simultaneously, reduced fan noise, make internal combustion engine operation more steadily promote the absorption of fan center's heat, effectively improved air flow property and the heat dispersion of IC. engine cooling fan, thereby improved the radiating efficiency of internal-combustion engine, improve the consumed power of motor, and then extended the working life of motor.And the interpolation of guide plate 203 design promotes fan blade 2 intensity simultaneously, make its overall structure better rationally reliable, extend the fan work Life cycle, reduce the raw material energy consumption.
The utility model further arranges: the recessed surface 202 of described blade 2 is provided with near wheel hub 1 position, place the connecting sheet 204 be connected with wheel hub 1, and described connecting sheet 204 parallels setting with the axial direction of wheel hub 1.By adopting technique scheme, when having guaranteed blade 2 intensity, reduced overall weight, thereby further reduced the consumed power of motor.
The utility model further arranges: the inboard of described wheel hub 1 is provided with to projecting inward land 101, described wheel hub 1 correspondence is provided with stiffening rib 102 with the inboard of the joint of blade 2, the axial section of the corresponding wheel hub 1 of described stiffening rib 102 arranges right-angled triangle, and two right angle sides of stiffening rib 102 are connected with wheel hub 1 and land 101 respectively.By adopting technique scheme, further, when having guaranteed blade 2 intensity, reduced overall weight, thereby further reduced the consumed power of motor.
