Abstract
The utility model discloses an engine cooling fan for a car in a high temperature region. The fan comprises an air protection cover (1) and a left fan (2) and a right fan (3) which are installed abreast in the air protection cover (1). Rotating directions of blades of the left fan (2) and the right fan (3) are opposite, the number of the blades of the left fan (2) is larger than that of the blades of the right fan (3), the diameter of the left fan (2) is larger than that of the right fan (3), and the blades of the left fan (2) are zigzag-shaped. Perturbation noise generated by uneven air flow is removed, and the air flow is utilized to the largest extent to improve the cooling effect and reduce vibration noise. Meanwhile, the contact area between the blades and the air flow is increased, driving force of the blades on the air flow is improved, and the air inlet quantity is further increased. The cooling effect of the cooling fan is remarkably improved under the premise that car load is not increased substantially. The cooling fan is especially applicable to engine cooling of the car in the high temperature region.
Description
Technical field
The utility model relates to motor car engine cooling technology field, relates in particular to a kind of fan for car engine cooling system.
Background technique
Motor, as the power of car, generally adopt water-cooling pattern to carry out cooling heat dissipation, and cooling fan is one of critical component of constituent, is the heat dissipation of water tank in constituent, and its performance directly affects the heat dispersion of car load.
Available engine cooling fan mostly is single blade, is placed between air-inlet grille and radiator, and blade is met windward slope.Along with the development of engine cooling technology, engender double-vane cooling fan, two blades side by side single direction rotation to strengthen cooling-down effect.But, limited by technical specifications, in the heat radiation requirement that still can not meet high temperature area car aspect air quantity and cooling-down effect.
Model utility content
The utility model improves for above-mentioned technical problem, intends providing a kind of applicable high temperature area cooling fan of engine that car is used, and not increasing considerably under the prerequisite of vehicle load, significantly promotes the cooling-down effect of cooling fan.
For this reason, the technological scheme that the utility model adopts is: a kind of high temperature area car cooling fan of engine, comprise wind shelling cover (1), be arranged on side by side left fan (2) and right fan (3) in wind shelling cover (1), the blade rotary opposite direction of described left fan (2) and right fan (3), key is: the blade quantity of described left fan (2) is more than the blade quantity of right fan (3), the diameter of left fan (2) is greater than the diameter of right fan (3), and the blade indention of left fan (2).
Be preferably, the blade quantity of described left fan (2) is 9, and the blade quantity of right fan (3) is 7, and the diameter of left fan (2) is 328 ± 5mm, and the diameter of right fan (3) is 309 ± 5mm.
Be provided with two screws (1a) in described wind shelling cover (1) top, be provided with two latches (1b) in wind shelling cover (1) below.Wind shelling cover top is bolted on upper header, and insert in the pin-and-hole of water tank lower header by latch below, thereby has realized the installation of cooling fan and fixed, and mounting structure is simple, mounting or dismounting are convenient.
Described left and right fan (2,3) is all with thermal baffle (4), and described thermal baffle (4) is placed in the drive motor rear of corresponding fan, plays isolation cabin distribute heat, extends the life-span of fan driving motor.
Beneficial effect is: the air-flow for car cooling fan installed position varies in size, take differentiation to design blade quantity, the fan diameter of left and right fan, to eliminate the noise that perturbs that air-flow inequality produced, maximally utilise air-flow to strengthen cooling-down effect, to reduce vibrating noise; Meanwhile, by the fan blade design toothing many blade quantity, diameter is large, to increase the area of contact of blade and air-flow, strengthen the Driving force of blade to air-flow, further improve air output.Not increasing considerably under the prerequisite of vehicle load, significantly promote the cooling-down effect of cooling fan, the motorcar engine that is particularly suitable for high temperature area is cooling.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
In conjunction with the high temperature area car cooling fan of engine shown in Fig. 1, Fig. 2, mainly by wind shelling cover 1, left fan 2,3, two drive motor of right fan, two transmission shaft compositions.Left fan 2 and right fan 3 are arranged in wind shelling cover 1 side by side, the blade rotary opposite direction of left fan 2 and right fan 3.Wind shelling cover 1 forms the installation frame of left fan 2, right fan 3, the corresponding drive motor of each fan and a transmission shaft, drive motor and corresponding fan blade are positioned on same transmission shaft, drive motor drives each self-corresponding fan blade to rotate by transmission shaft, the sense of rotation of two drive motor is contrary, the blades installation opposite direction of two fans, fan blade counterrotating, forms air-flow to reduce radiator shell temperature.The above is existing application in existing double-vane cooling fan, does not repeat them here.
The blade quantity of left fan 2 is more than the blade quantity of right fan 3, and the diameter of left fan 2 is greater than the diameter of right fan 3, and the blade indention of left fan 2.Left fan 2 and right fan 3 quantity are preferably odd number, to meet the design code of automobile fan.
Be preferably, the blade quantity of left fan 2 is 9, and the blade quantity of right fan 3 is 7, and the diameter of left fan 2 is 328 ± 5mm, and the diameter of right fan 3 is 309 ± 5mm.
Above wind shelling cover 1, be provided with two screw 1a, below wind shelling cover 1, be provided with two latch 1b.Wind shelling cover 1 is made up of PA66.
Left and right fan 2,3 is all with thermal baffle 4, and thermal baffle 4 is placed in the drive motor rear of corresponding fan.Thermal baffle 4 is made up of smooth exotic material, plays isolation cabin distribute heat.In Fig. 2, direction shown in arrow is airflow direction, determines front and back position with airflow direction.
