In order to solve the problem that the mixing ratio of air and gasoline is small, the utility model with the publication number of CN201671705U discloses a turbocharger, which comprises an impeller and blades which are twisted at a certain angle around the periphery of the impeller along the same direction, and the turbocharger is installed on an air inlet pipeline and close to a throttle end, so that air forms an air vortex before entering a cylinder, and the amount of air entering the cylinder is increased. However, the turbocharger of this structure cannot increase the amount of air taken into the cylinder significantly, and the improvement effect is not significant.

SUMMERY OF THE UTILITY MODEL

In order to further improve the amount of air entering the cylinder, according to an aspect of the present invention, a high efficiency vortex supercharging device is provided.

This high-efficient vortex supercharging device includes: a support bar; at least one guide vane which is arranged on the periphery of the support rod, extends along the direction departing from the support rod and is twisted at the same time; the first flow guide body is arranged at one end of the support rod and extends in the direction away from the opposite end of the support rod to form a cone; the second flow guiding body is arranged at the opposite end of the supporting rod and extends to the direction back to the first flow guiding body to form a conical shape. When using this high-efficient vortex supercharging device, install this high-efficient vortex supercharging device on the admission line, and be located between admission line and the air throttle, simultaneously, first baffle orientation admission line, second baffle orientation air throttle, when the engine is in the air intake stroke, piston in the engine is from the downward extremely motion of top dead center, the working volume of cylinder increases, the working volume's of cylinder atmospheric pressure reduces, atmospheric pressure in the environment is greater than the working volume's of cylinder atmospheric pressure this moment, air in the environment is in proper order through the admission line, the utility model discloses an after the high-efficient vortex supercharging device with the air throttle, finally get into in the working volume of cylinder. When the vortex supercharging device in the background art is adopted, because the top of the vortex supercharging device is hemispherical, gas flowing through the vortex supercharging device can form loose airflow at the hemispherical top, so that the vortex supercharging device in the background art has a poor effect of improving the speed of air flowing through the vortex supercharging device. When the high-efficiency vortex supercharging device of the utility model is adopted, when passing through the high-efficiency vortex supercharging device, the first flow guide body extends from the end part of the support rod to the direction deviating from the support rod to form a cone shape, when air flows into the high-efficiency vortex supercharging device from one side where the first flow guide body is positioned, the resistance of the cone-shaped first flow guide body to the flowing-in air is smaller, the air can be enabled to pass through quickly, the air is prevented from forming loose airflow at the top of the high-efficiency vortex supercharging device, the speed of the air flowing through the high-efficiency vortex supercharging device is increased, so that in the air inlet stroke at the same time, more air enters the working volume of the cylinder, namely more air mixed with gasoline in the cylinder, the gasoline is combusted more sufficiently, the power of the engine can be enhanced, the generation of carbon deposition in the cylinder can be reduced, and the accurate transmission of signals of the engine control unit is ensured, and pollutants in the exhausted tail gas can be reduced.

From this, when can avoiding this high-efficient vortex supercharging device to install the one end of admission line, hinder and install the filter at the admission line looks remote site, guarantee this high-efficient vortex supercharging device's suitability and commonality.

In some embodiments, the free end of the second flow conductor transitions smoothly. The free end of the second flow guiding body is in smooth transition, so that the second flow guiding body can be prevented from obstructing the connection of the high-efficiency vortex supercharging device and the throttle valve; on the other hand, the air flowing through the high-efficiency vortex booster device can be facilitated to flow into the throttle valve.

In some embodiments, the taper of the first current carriers and the second current carriers is between 10 ° and 80 °. The first flow guiding body and the second flow guiding body with the conicity of 10-80 degrees are adopted, on one hand, the conicity of the first flow guiding body and the conicity of the second flow guiding body are both larger than 10 degrees, so that the first flow guiding body and the second flow guiding body can be prevented from being broken easily due to collision because the shapes of the first flow guiding body and the second flow guiding body are too thin and long, and the service lives of the first flow guiding body and the second flow guiding body are prolonged; on the other hand, the conicity of the first flow guiding body and the conicity of the second flow guiding body are both smaller than 80 degrees, so that the problem that when the conicity of the first flow guiding body and the conicity of the second flow guiding body are larger than 80 degrees, the flow guiding effect is lost due to the fact that the surface of the cone is close to the plane, and the flow guiding effect of the first flow guiding body and the second flow guiding body is guaranteed.

In some embodiments, the high efficiency vortex booster further comprises an annular housing, which is sleeved outside the support bar and the guide vanes and connected with the guide vanes. Because the annular shell is arranged on the guide vane, when the high-efficiency vortex supercharging device is arranged on the air inlet pipeline, the annular shell can be adapted in the air inlet pipeline, so that the high-efficiency vortex supercharging device is conveniently connected with the air inlet pipeline through the annular shell; and owing to set up annular housing, increase this high-efficient vortex supercharging device and admission line's area of contact, avoid in the use, this high-efficient vortex supercharging device removes or rocks in the admission line.

In some embodiments, the annular housing is disposed coaxially with the support rod. Because the first guide body and the second guide body are formed by extending on the supporting rod, the guide vanes are arranged on the periphery of the supporting rod, when the annular shell and the supporting rod are coaxially arranged, air flowing through the high-efficiency vortex supercharging device uniformly flows into the area where the guide vanes are positioned after being subjected to the guide effect of the first guide body, and then uniformly flows into the air cylinder through the throttle valve under the guide effect of the second guide body, so that the uniformity and the stability of the air flowing into the air cylinder are ensured.

In some embodiments, the annular housing is provided with at least one through groove penetrating two ends of the annular housing, and the annular housing and the guide vanes are made of elastic high-temperature-resistant materials. Because the size specifications of the air inlet pipeline and the throttle valve of automobiles with different models are inconsistent, in order to improve the universality of the high-efficiency vortex supercharging device, at least one through groove which runs through the two ends of the annular shell is arranged on the annular shell, and the annular shell is prepared by adopting an elastic material, so that when the sizes of the air inlet pipeline and the throttle valve are slightly larger than the size of the annular shell, the annular shell can be pulled to deform and increase the width of the through groove, and at the moment, the outer diameter of the annular shell is increased, so that the annular shell can be matched with the air inlet pipeline and the throttle valve; when the sizes of the air inlet pipeline and the throttle valve are slightly smaller than the size of the annular shell, the annular shell can be extruded to deform and reduce the width of the through groove, and the outer diameter of the annular shell is reduced at the moment so that the annular shell can be matched with the air inlet pipeline and the throttle valve; meanwhile, the annular shell and the guide vanes are made of high-temperature-resistant materials, so that the annular shell and the guide vanes can be used in a high-temperature environment, and the phenomenon that the annular shell and the guide vanes deform in the high-temperature environment, the connection part of the annular shell and the air inlet pipeline is loosened, and the guide effect of the guide vanes is poor is avoided; preferably, the elastic high-temperature-resistant material can be a carbon fiber material, and the annular shell and the guide vanes made of the carbon fiber material can also ensure that the annular shell and the guide vanes have the advantages of light weight and high temperature resistance.

In some embodiments, the through slots are arranged such that the annular housing presents a closed circle in projection in the direction of its own axis. Therefore, even if the through groove is formed, the length of the outer wall of the annular shell contacting with the inner walls of the air inlet pipeline and the throttle valve in the circumferential direction can be ensured, and the annular shell is stably sleeved in the air inlet pipeline and the throttle valve.

In some embodiments, the through-slots are arranged in a ">" or "<" shape. Therefore, the end parts of the annular shells on the two sides of the through groove are respectively in the concave shape and the convex shape, and the convex end parts are embedded into the concave end parts, so that the two end parts of the annular shells are prevented from being staggered when the annular shells are sleeved in the air inlet pipeline and the throttle valve, and the roundness of the annular shells in the air inlet pipeline and the throttle valve is ensured.

In some embodiments, four guide vanes are uniformly distributed on the support rod, and a through groove is formed between every two adjacent guide vanes. Therefore, on one hand, the four guide vanes uniformly distributed on the support rod can keep the uniformity of the air flowing through the high-efficiency vortex supercharging device, and simultaneously increase the distortion degree of the air flowing through the high-efficiency vortex supercharging device, and further increase the flow rate of the air; on the other hand, all set up logical groove between per two adjacent guide vane, can reduce the deformation degree of difficulty of annular shell on the whole.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 to 6 schematically show a high-efficiency vortex supercharging device according to an embodiment of the present invention.

As shown in fig. 1, 3 and 4, the high-efficiency vortex supercharging device comprises a support rod 20, a first guide body 40, a second guide body 50 and at least one guide vane 30, wherein the support rod 20 is preferably configured to be cylindrical, the guide vane 30 is connected to the outer periphery of the support rod 20 by machining or fixing, and the guide vane 30 extends in a direction away from the support rod 20 and is twisted to form a spiral vane; the first flow guiding body 40 is formed by processing or fixedly connecting one end of the supporting rod 20, the first flow guiding body 40 is arranged in a conical shape, and the diameter of the end close to the supporting rod 20 is larger; similar to the formation of the first current carriers 40, the second current carriers 50 are formed by machining or fixedly coupling opposite ends of the support rod 20, and the second current carriers 50 are also formed in a conical shape and have a larger diameter near the end where the support rod 20 is located.

When air in the environment passes through the high-efficiency vortex supercharging device, because the first guide body 40 is conical, the air can rapidly pass through the first guide body 40, loose airflow can not be formed at the top of the first guide body 40 when the air flows through the first guide body, the speed of the air flowing through the high-efficiency vortex supercharging device is accelerated through the conical first guide body 40, so that more air enters the working volume of the cylinder in the air inlet process at the same time, namely more air mixed with gasoline in the cylinder, the gasoline is more sufficiently combusted, the power of the engine can be enhanced, the generation of carbon deposition in the cylinder can be reduced, the accuracy of signal transmission and receiving of electronic components in the engine is ensured, and pollutants in the exhausted tail gas can be reduced.

However, if the turbocharger of the prior art is adopted, as shown in fig. 13, since the first flow guiding body is configured as the hemispherical protrusion 100, when air flows through the hemispherical protrusion 100, the deflection of the air is large, which results in a low density of air around the supporting rod 20 below the hemispherical protrusion 100, and a loose air flow is formed at the top of the hemispherical protrusion 100, thereby reducing the air flow rate; moreover, since the air is deflected at a large angle when passing through the hemispherical protrusion 100, the air cannot smoothly flow into the air where the guide vane 30 is located, so that the air flow rate of the air passing through the turbocharger in the prior art cannot be well increased, the amount of air entering the working volume of the cylinder cannot be increased to a great extent, the improvement on the sufficient combustion of gasoline is not obvious enough, the power of the engine is not obviously enhanced, the carbon deposition in the cylinder is not obviously reduced, errors are easily caused in the signal transmission of the engine control unit, and the pollutants in the exhaust gas are not obviously reduced.

In order to clearly see the effect of improving the air flow rate of the high-efficiency vortex supercharging device and the prior art vortex supercharger of the present invention, the air flowing through the high-efficiency vortex supercharging device of the present invention and the prior art vortex supercharger with the same specification is simulated by the fluid analysis (FloXpress) tool of SolidWorks, the temperature of the test is set to 293.2K, the ambient pressure before flowing into the high-efficiency vortex supercharging device of the present invention and the prior art vortex supercharger is 101325Pa, the ambient pressure after flowing into the high-efficiency vortex supercharging device of the present invention and the prior art vortex supercharger is 100325Pa, the test result is shown in FIG. 12 and FIG. 14, the simulation shows that the flow rate of the air after flowing through the high-efficiency vortex supercharging device of the present invention and the prior art vortex supercharger is increased, the maximum speed of the air flowing through the high-efficiency vortex supercharging device of the present invention is 54.225m/s, the maximum speed of the air which is larger than the air flowing through the vortex supercharger in the prior art is 53.712m/s, and therefore, the high-efficiency vortex supercharging device can better increase the flow speed of the air.

Preferably, the length L1 of first current carrier 40 is less than 25 mm. From this, when can avoiding this high-efficient vortex supercharging device to install the one end of admission line, hinder and install the filter at the admission line looks remote site, guarantee this high-efficient vortex supercharging device's suitability and commonality. The length of the first current carriers 40 is ensured to be shorter than 25mm, and the first current carriers 40 are made as long as possible to ensure the current guiding effect.

Preferably, the length L2 of the guide vane 30 in the axial direction of the first guide body 40 is not less than 15mm to ensure sufficient flow guiding effect.

Preferably, second current carriers 50 have a length of 8mm to 12 mm. This is because, on the one hand, the second flow guiding body 50 needs to have a certain length so as to have a positioning effect during installation, and on the other hand, the length of the second flow guiding body 50 is not too long so as to avoid reducing the flow guiding effect.

Preferably, as shown in fig. 2, the diameter D1 of the support rod 20 is not less than 10mm, which ensures the strength of the support rod 20 and the flow guiding effect of the first flow guiding body 40 and the second flow guiding body 50.

The free end of the second guide body 50 is in smooth transition, so that the second guide body 50 can be prevented from obstructing the connection of the high-efficiency vortex supercharging device and the throttle valve; on the other hand, the air flowing through the high-efficiency vortex booster device can be facilitated to flow into the throttle valve. Specifically, the free end of the second flow guiding body 50 is smoothly transitioned as shown in fig. 6, and a fillet R is rounded at the end of the second flow guiding body 50, where the size range of the fillet R may be 0.2mm to 2mm, so as to ensure the flow guiding effect of the second flow guiding body 50.

Preferably, as shown in fig. 4-6, first current carriers 40 and second current carriers 50 taper at 10-80 degrees. The first flow guiding body 40 and the second flow guiding body 50 with the conicity of 10-80 degrees are adopted, so that the strength of the first flow guiding body 40 and the second flow guiding body 50 can be ensured on one hand, and the flow guiding effect of the first flow guiding body 40 and the second flow guiding body 50 can be ensured on the other hand.

Preferably, as shown in fig. 2, the diameter D2 enclosed by the guide vane 30 is adapted to the inner diameters of the intake duct and the throttle valve, so that the high-efficiency vortex supercharging device is sleeved in the intake duct and the throttle valve.

Fig. 7 to 11 schematically show a high-efficiency vortex supercharging device according to another embodiment of the present invention.

The difference from the aforementioned high-efficiency vortex supercharging device is that, as shown in fig. 7 to 11, the high-efficiency vortex supercharging device further includes an annular housing 60, the annular housing 60 is sleeved outside the support rod 20 and the guide vane 30 in a machining or fixed connection manner, and is fixedly connected with the guide vane 30, and a flow passage 70 for gas to flow through is defined by the annular housing 60, the support rod 20 and the guide vane 30. Due to the annular housing 60 arranged on the guide vane 30, the high-efficiency vortex supercharging device is convenient to be connected with the air inlet pipeline and the throttle valve through the annular housing 60, for example, a thread or a snap structure can be arranged on the annular housing 60 to realize the threaded connection or the snap connection of the annular housing 60 with the air inlet pipeline and the throttle valve.

Preferably, as shown in fig. 8, the annular housing 60 is coaxially disposed with the support rod 20. Because the first guide body 40 and the second guide body 50 are formed by extending on the support rod 20, and the guide vanes 30 are disposed at the periphery of the support rod 20, when the annular housing 60 is disposed coaxially with the support rod 20, the air flowing through the high-efficiency vortex supercharging device uniformly flows into the area where the guide vanes 30 are located after being guided by the first guide body 40, and then uniformly flows into the cylinder through the throttle valve under the guiding action of the second guide body 50, thereby ensuring uniformity and stability of the air flowing into the cylinder.

Because the sizes and specifications of the air inlet pipeline and the throttle valve of automobiles with different models are not consistent, in order to improve the universality of the high-efficiency vortex supercharging device, at least one through groove 61 which penetrates through the two ends of the annular shell 60 is arranged on the annular shell 60, when the sizes of the air inlet pipeline and the throttle valve are slightly larger than the size of the annular shell, the annular shell 60 can be pulled to deform, the width of the through groove 61 is increased, and at the moment, the outer diameter of the annular shell 60 is increased, so that the annular shell can be matched with the air inlet pipeline and the throttle valve; when the sizes of the air inlet pipeline and the throttle valve are slightly smaller than the size of the annular shell 60, the annular shell 60 can be extruded to deform, the width of the through groove 61 is reduced, and the outer diameter of the annular shell 60 is reduced to enable the annular shell to be matched with the air inlet pipeline and the throttle valve; moreover, the annular housing 60 and the guide vanes 30 are made of carbon fiber, so that the weight of the housing can be reduced, and the heat resistance of the housing can be improved.

Preferably, in order to make the high-efficiency vortex adding apparatus heat-resistant as a whole, the support rod 20, the first current carriers 40, and the second current carriers 50 are also made of a material having elasticity and high temperature resistance, such as carbon fiber.

Further, in order to ensure the length of the outer wall of the annular housing 60 contacting the inner walls of the air inlet duct and the throttle valve in the circumferential direction, and ensure that the annular housing 60 is stably sleeved in the air inlet duct and the throttle valve, the through groove 61 is configured to make the projection of the annular housing 60 in the axial direction of the annular housing 60 be a closed ring.

Specifically, as shown in fig. 7 to 11, the through groove 61 is not parallel to the axis of the first current carrier 40.

In one embodiment of the through groove 61 as shown in fig. 10 and 11, when the through groove 61 is a through groove and the annular housing 60 is not adapted to the inner diameters of the intake duct and the throttle valve, and the annular housing 60 is required to be deformed to be able to be mounted in the intake duct and the throttle valve, the annular housing 60 provided with the through groove is deformed such that the two ends of the through groove are misaligned, and it is difficult to ensure the roundness of the annular housing 60, as shown in fig. 11.

Preferably, the length of the through groove 61 in the circumferential direction of the annular housing 60 is not shorter than 20mm, so as to reduce the difficulty of deformation of the annular housing 60.

Another embodiment of the through groove 61 is shown in fig. 7 to 9, in which the through groove 61 is provided in a ">" or "<" shape. Therefore, the end parts of the annular shell 60 on the two sides of the through groove 61 are respectively in the concave shape and the convex shape, and the convex end part is embedded into the concave end part, so that when the annular shell 60 is sleeved in the air inlet pipeline and the throttle valve, the two end parts are prevented from being staggered, and the roundness of the annular shell 60 after deformation is ensured, thereby ensuring the roundness of the annular shell 60 sleeved in the air inlet pipeline and the throttle valve.

No matter the through grooves 61 of any one of the above structures are adopted, in order to ensure the flow guiding effect of the guide vanes 30, as shown in fig. 7 to 11, four guide vanes 30 are uniformly distributed on the support rod 20, and one through groove 61 is arranged between every two adjacent guide vanes 30. Therefore, on one hand, the four guide vanes 30 uniformly distributed on the support rod 20 can keep the uniformity of the air flowing through the high-efficiency vortex supercharging device, and simultaneously increase the distortion degree of the air flowing through the high-efficiency vortex supercharging device, and further increase the flow velocity of the air; on the other hand, the through groove 61 provided between two adjacent guide vanes 30 can reduce the difficulty of deformation of the annular housing 60.
