Yielding and poor balance problem, and when IC. engine cooling fan work, its central gas stream will appear disorder and generate
Noise causes internal combustion engine operation unstable so that the mobility and poor radiation of air, to reduce the heat dissipation effect of internal combustion engine
Rate makes the consumption power of internal combustion engine increase, so that influencing the service life of internal combustion engine.
Invention content
In view of background technology, the technical problem to be solved by the present invention is to provide a kind of balance effects
The IC. engine cooling fan that fruit is good, cooling effect is good.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that realize：This kind of internal combustion engine
Cooling fan includes circular hub and several blades, and the root of the blade and the outer circumference surface of wheel hub connect, and the leaf
Piece is along the circumferential direction evenly distributed, and the end of the blade is connect with cyclic annular outer ring body, the blade tilted set, and the leaf
The root of piece is higher than end, it is characterised in that the upper surface of the blade is equipped with auxiliary guide vane, the auxiliary water conservancy diversion leaf
The end face of piece and blade is vertically arranged, and the auxiliary guide vane is along the circumferential direction evenly distributed.
Water conservancy diversion through-hole is offered on the end face of the wheel hub, the water conservancy diversion through-hole is along the circumferential direction uniformly arranged.
The end face of the wheel hub has quincunx gas channel, and the gas channel is mutually staggered with water conservancy diversion through-hole and set
It sets.
The auxiliary guide vane is in arcuation, and the auxiliary guide vane is arranged in the root of blade.
Reinforcing rib is provided on the lower face of the wheel hub, the reinforcing rib is along the circumferential direction evenly distributed.
The utility model has added auxiliary guide vane on blade, and fraction is made to be further separated into fan center position,
Auxiliary guide vane reduces central gas stream disorder simultaneously, keeps internal combustion engine operation more stable, promotes the absorption of fan center's heat, adds
Fast heat dissipation, extends the service life of internal combustion engine；And the auxiliary guide vane be arcuation and be arranged the root of blade not only
With better water conservancy diversion effect, moreover it is possible to so that the stress intensity of root of blade is strengthened, and the utility model is under wheel hub
End face is also provided with reinforcing rib, improves the intensity of fan, avoids deforming；The setting of gas channel on the wheel hub improves wind
Ventilation quantity is fanned, helps to ensure that the circulation of fan center's cooling air-flow, improves cooling effect, and with the work for reducing noise
With.
Description of the drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the rearview of the utility model.
Specific implementation mode
The operation principle of the utility model and its related details are further described below in conjunction with the accompanying drawings.With reference to attached drawing, this kind
IC. engine cooling fan includes circular hub 4 and ten a piece of blades 1；Referring to Fig.1, the blade is arcuation in width direction,
The upper surface of the blade 1 raises up, and the lower face of the blade 1 is then recessed, and the root of the blade 1 is outer with wheel hub 4
Periphery connects, and ten a piece of blades are along the circumferential direction evenly distributed, and the end of the blade 1 is connect with cyclic annular outer ring body 7, institute
It states blade 1 to be obliquely installed, and the root of the blade 1 is higher than end, the outer ring body 7 makes blade that can reduce in rotary course
Air turbulence reduces the noise that blade tip generates, reaches muting function, and the setting of outer ring body 7 improves blade and revolving
The degree of balance during turning keeps internal combustion engine operation more quiet steady.Reinforcing rib 8, institute are provided on the lower face of the wheel hub 4
State that reinforcing rib 8 is along the circumferential direction evenly distributed, the setting of the reinforcing rib 8 improves the intensity of wheel hub 4 and fan, and fan is avoided to become
Shape；Water conservancy diversion through-hole 6 is offered on the end face of the wheel hub 4, the water conservancy diversion through-hole 6 is along the circumferential direction uniformly arranged, the wheel hub 4
End face there is quincunx gas channel 5, and the gas channel 5 and water conservancy diversion through-hole mutually stagger setting, because of the end face of wheel hub
Quincunx gas channel is opened up, water conservancy diversion through-hole 6 is then located just between petal, and reinforcing rib 8 is then arranged in wheel hub end face
Remainder, the setting of the gas channel 5 improves the mobility of air-flow, improves the ventilation quantity of fan, contribute to wind
The circulation of fan center cooling air-flow, improves the utilization rate of cooling effect and fuel oil, while also having the function of noise reduction.The blade
1 upper surface is equipped with auxiliary guide vane 2, and the auxiliary guide vane 2 is consistent with the quantity of blade 1, the auxiliary water conservancy diversion
Blade 2 is in arcuation, and along the circumferential direction evenly distributed, forms the shape of Hot Wheels, the auxiliary guide vane 2 makes fraction
It is further separated into fan center position, auxiliary guide vane 2 reduces central gas stream disorder, keep internal combustion engine operation more stable, promotees simultaneously
