Description
Technical field
The utility model is related to a kind of engine cooling apparatus, especially a kind of silicon-oil fan.
Background technology
Automobile in the process of moving, especially heavy goods vehicle and engineering truck in the process of moving, due to environmental condition
Also changing with the hot situation of the variation of operating condition, engine.Therefore, it is necessary to adjust the intensity of cooling of engine at any time.Example
Such as, during the broiling summer, engine is in low speed, big working under load, and when the temperature of coolant liquid is very high, fan should high speed rotation
To increase cooling air quantity, enhance the heat-sinking capability of radiator；And in cold winter, when coolant temperature is relatively low, or in automobile
When powerful heading on of running at high speed blows air over radiator, fan, which works on, just becomes meaningless.Not only consume in vain
Engine power, but also generate prodigious noise.Its intensity of cooling is adjusted just at any time according to the hot situation of engine
Seem particularly significant.The device silicon oil filled fan clutch between blower pulley and cooling fan, both silicon-oil fan was to realize this
One of the method that kind is adjusted.
Silicon oil filled fan clutch, uses silicone oil as medium, and torque is transmitted using silicone oil shearing viscous force.The rotating speed of fan is to examine
What worry designed under conditions of when use condition is most severe, guarantee engine does not overheat, therefore, in the usual driving process of vehicle,
The rotating speed of fan should be controlled in proper range, noise could be reduced in this way, improve engine economy.For engine
The fan of driving controls its rotating speed usually using fan clutch.Toughness fluid is sealed inside clutch（Silicone oil）, by its shearing
Viscous force transmits torque.Bimetal leaf is housed before fan, with its induction by the air themperature of radiator, thus controls fan
Silicone oil amount in working chamber, only if necessary, could transmit torque makes fan rotate.
But silicon-oil fan can also send out very strong noise in the running, and, warp louder with the increase noise of rotating speed
Cross research shows that the blade of fan it is more long then noise is stronger under same rotational speed, contract if silicon-oil fan is with the raising of rotating speed
The size of vanelets then can further reduce noise content.
Utility model content
The utility model is directed to deficiency in the prior art, provides a kind of silicon oil filled fan clutch, is arranged in silicone oil wind
Fan flabellum can be unfolded under the influence of centrifugal force in silicon oil filled fan clutch low-speed running on fan clutch, to increase air inlet
Amount reinforces radiating efficiency, flabellum is shunk when silicon oil filled fan clutch runs at high speed, to reduce noise, solves previous silicone oil wind
Intake is few when fanning low-power, noise big problem when high power.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of silicon-oil fan

Electromagnet array.
In above-mentioned technical proposal, it is preferred that rounding off between the blade and the inserted sheet.
In above-mentioned technical proposal, it is preferred that rounding off at the top of the holding tank both ends.
The utility model is a kind of silicon oil filled fan clutch, and silicon oil filled fan clutch further includes the fan being disposed thereon,
Fan blade is divided into blade and lower blade, and blade and lower blade opposite can slide, both blade area and length of blade
It can become larger and become smaller.It is well known under equal rates, the length of blade is longer, area is bigger, then ventilation quantity is more, but blade
More longer, bigger noise at runtime is louder.Therefore the utility model is increased often in the operation of silicon oil filled fan clutch low speed
The size and area of a blade also obtain larger intake when silicon oil filled fan clutch low speed, ensures that engine carries out
Carry out low speed operation cooling, that silicon oil filled fan clutch can be allowed to stablize reduces the time of silicon oil filled fan clutch high-speed cruising.Such as
When fruit silicon oil filled fan clutch needs high-speed cruising, by the way that the electromagnet array in blade and lower blade and iron bar energy is arranged
It allows blade and lower blade to bounce back, reduces the size and area of blade so that noise content is reduced.Because in silicon oil filled fan clutch
The part of leaf blade size and area changes the variation that intake will not be allowed to generate matter when high-speed cruising, instead then noise level meeting
Drastically increase.The present apparatus is run under silicon oil filled fan clutch capable of being made to be in low power state for a long time in heat dissipation, even if in Gao Gong
Being run under rate also can significantly reduce fan noise, and the present apparatus is particularly suitable for the large-scale loading lorry with big-block engine
And large-scale engineering machinery equipment.
Compared with prior art, the utility model has the beneficial effects that：Fan is arranged on silicon oil filled fan clutch can be
Flabellum is unfolded under the influence of centrifugal force when silicon oil filled fan clutch low-speed running, to increase intake, reinforces radiating efficiency,
Flabellum is shunk when silicon oil filled fan clutch runs at high speed, to reduce noise, it is few to solve intake when previous silicon-oil fan low-power,
Noise big problem when high power.
