Description
[technical field]
This utility model relates to a kind of engine-cooling system assembly, particularly relates to the fan of a kind of silicon oil filled fan clutch.
[background technology]
Car engine cooling system includes water pump, fan, the clutch of driving fan, radiator and associated component.Coolant in engine water jacket is done the waste heat carried and is exchanged through second heat by radiator, and the heat forcing to be absorbed by hot parts under airflow function at cooling fan is dispersed in air, makes electromotor work under optimum working temperature.At present, drive the clutch of fan typically to use silicon oil filled fan clutch, with silicone oil as medium, utilize the full-bodied characteristic of silicone oil to transmit moment of torsion.Utilize the temperature of air after radiator, automatically controlled separation and the joint of fan clutch by temperature detector.When temperature is low, silicone oil does not flows, and fan clutch separates, and rotation speed of the fan slows down, substantially idle running.During temperature height, silicon oil viscosity makes fan clutch combine, and then fan rotates together with pump shaft, plays the effect of regulation engine temperature.Fan, when being in rotation status, can produce eddy current wind.What prior art wind was fanned is designed without evacuating eddy current wind, and eddy current wind, owing to can not immediately be evacuated away, can form sinuous flow in annular wheel hub, wheel hub is produced irregular impact；Simultaneously as sinuous flow can not exhale to surrounding so that the pressure of fan center is the highest, it is impossible to make more wind head-on enter, effectively cool down, reduce efficiency and the endurance impact strength of fan, also reduce physical life.
[summary of the invention]
The present invention for the problems referred to above of the prior art, it is provided that a kind of clutch fan, it is possible to increase the radiating effect of fan.
This technical scheme is:
A kind of clutch fan, including wheel hub and flabellum, described flabellum is connected by annular connecting portion with wheel hub, it is characterized in that, described flabellum comprises flabellum body and diversion section, one end of described diversion section is connected with one end of flabellum body, and the other end is connected with the inward flange of annular connecting portion, and described diversion section bends along the opposite direction of described flabellum body bending direction.When the fan is operating, the direction along diversion section is outwards dissipated by the eddy current that fan center produces, and reduces the sinuous flow in annular wheel hub, decreases the irregular impact producing wheel hub；Simultaneously as central vortex is effectively evacuated, outside air-flow enters the drag reduction of fan center, and the flowing of gas is more smooth, is also effectively improved cooling effectiveness.
Further, the contour line of above-mentioned diversion section is with the inward flange involute as basic circle of annular connecting portion.The contour line of involute can dissipate effectively by the mildest for the eddy current of fan center's generation.
Further, on the extended line of the centrage that one end of above-mentioned diversion section is positioned at described flabellum body.So can make that diversion section length is longer, arrangement is more orderly, the effect of divergent vortex flow is more preferable.
Further, above-mentioned flabellum is provided with strengthening segment, and described strengthening segment is arranged on the one side contrary with diversion section, and one end of described strengthening segment is connected with flabellum body, and the other end is connected with the inward flange of annular connecting portion.Arranging of strengthening segment can make flabellum body the most firm with the connection of annular connecting portion, the flabellum Mass Distribution on wheel hub two sides can also be made relatively uniform simultaneously.
Further, the contour line of above-mentioned strengthening segment is straightway.The strengthening segment mould of straightway is simple, cost ratio is relatively low, it is also possible to realize adding the effect being solidly connected with homogeneous quality.
Further, above-mentioned wheel hub is provided with hole, location.The assembling with clutch beneficially below that is provided with in hole, location positions.
Further, above-mentioned flabellum is formed in one.One-body molded processing is simple, it is only necessary to specific mould, it is not necessary to extra operation, practical.
This technical scheme has a following useful technique effect:
1) this utility model arranges the diversion section that the opposite direction of oriented flabellum body bending direction bends, be conducive to by fan running time, the eddy current wind that produces of fan center exhale, reduce the sinuous flow and the impact to wheel hub that thus brings formed in annular wheel hub；Meanwhile, eddy current wind is exported effectively, and the oncoming wind of fan center is easier to into, accelerates gas flowing, and the radiating efficiency of fan is higher, and the physical life of fan is higher；And the involute contour of diversion section and centrage start position design, it is possible to more effectively improve the water conservancy diversion effect to gas.
2) strengthening segment that this utility model another side is arranged, it is possible to strengthen firmness and the dynamic balancing of fan of flabellum, it is possible to improve radiating efficiency and the endurance impact strength of fan further.
3) this utility model is provided with hole, location, facilitates the fixed and positioned of fan.
4) flabellum of the present utility model is formed in one, it is not necessary to extra operation and parts, when efficiently solving fan running, the sinuous flow problem that produces of fan center.

Embodiment
A kind of clutch fan, as it is shown in figure 1, include wheel hub 1 and flabellum, described flabellum is connected by annular connecting portion 3 is fixing with wheel hub 1.Described flabellum comprises flabellum body 201 and diversion section 202, one end of diversion section 202 is connected with one end of flabellum body 201, the other end is connected with the inward flange of annular connecting portion 3, described diversion section 202 bends (as in Fig. 2, flabellum body 201 bends clockwise, diversion section 202 bends counterclockwise) along the opposite direction of described flabellum body 201 bending direction.When fan in the running, the direction along diversion section is outwards dissipated by the eddy current that fan center produces, and reduces the sinuous flow in annular wheel hub, decreases the irregular impact producing wheel hub；Simultaneously as central vortex is effectively evacuated, outside air-flow enters the drag reduction of fan center, and the flowing of gas is more smooth.The contour line of described diversion section 202 is with the inward flange involute as basic circle of annular connecting portion 3.On the extended line of the centrage that one end that described diversion section 202 is connected with the inward flange of annular connecting portion 3 is positioned at described flabellum body 201.Described flabellum is provided with strengthening segment 203, and described strengthening segment 203 is arranged on the one side contrary with diversion section 202, and one end of described strengthening segment 203 is connected with flabellum body 201, and the other end is connected with the inward flange of annular connecting portion 3.(contour line of 203 is straightway in described reinforcement.Described wheel hub 1 is provided with hole 101, location, location during convenient installation.Described flabellum is formed in one, it is not necessary to extra operation and part, it is possible to reduce cost.The clutch fan of the present embodiment is compared with the clutch fan not having diversion section, and under the same terms, radiating efficiency improves about 10%, and the life-span adds about 7%.
