Technical Field

[0001] The present invention relates to the technical field of intercoolers, and particularly to an engine air compression device. Background Art

[0002] As the power source of the vehicle as a whole, in order to improve the efficiency and output power of the engine, the production of existing vehicles is usually equipped with an air compression device, such as a turbocharger. However, when the supercharger increases the intake air, the density of the air will also decrease due to the increase in air temperature. For this reason, an intercooler is also required to perform a cooling process. However, the existing intercooler only simply adopts an air-cooled or liquid-cooled working mode, which cannot match the working requirements of the vehicle in different states, thus affecting the combustion effect inside the engine. Summary of the Invention

[0003] The technical problem to be solved by the present invention is, in view of the above-mentioned existing technical deficiencies, to provide an engine air compression device that can complete the switching of modes according to different states of the vehicle, ensure that stable intake air can be provided during operation, and improve the combustion efficiency.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is as follows: It includes an air inlet end and an air outlet end; the air inlet end and the air outlet end are arranged opposite to each other, and a water-cooling component and an air-cooling component are respectively provided therebetween. Both ends of the water-cooling component and the air-cooling component are communicated with the air inlet end and the air outlet end respectively, and an adjustment device for channel switching is provided inside the air inlet end.

[0005] Preferably, two groups of ventilation openings are respectively provided inside the air inlet end. Each ventilation opening is arranged at equal intervals in the height direction, and the height directions between the two groups of ventilation openings are arranged in a staggered manner.

[0007] Preferably, the water-cooling component includes a water-cooling channel and a box plate; both ends of a plurality of water-cooling channels and the box plate are fixedly connected to the air inlet end and the air outlet end respectively. The box plate wraps a plurality of water-cooling channels therein, and a plurality of water-cooling channels divide the interior of the box plate into a plurality of flow channels, and the adjacent two flow channels are in a communicating state. Two water inlet pipes are symmetrically provided on the left side of the box plate, and a water outlet pipe is provided in the middle of the right side.

[0008] Preferably, a penetration hole is provided on the box plate between the adjacent two water-cooling channels.

[0009] Preferably, a plurality of flow dividing plates are uniformly provided inside the penetration hole.

[0010] Preferably, the air-cooling component includes an air-cooling channel and heat dissipation fins; both ends of the plurality of air-cooling channels are fixedly connected to the air inlet end and the air outlet end respectively, and heat dissipation fins are installed above each air-cooling channel.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. When the vehicle is running at a low speed or idling, it can be switched to water cooling, and when driving at a high speed, it can be switched to air cooling to ensure that the temperature of the incoming compressed air is low, guarantee the combustion efficiency inside the engine, and during extreme movement, the combination of both can be adopted to cool the incoming air at the same time, reduce the working burden under a single channel, and improve stability;

[0016] 2. The coolant forms a continuous bending movement in the flow channel, and the coolant is provided simultaneously from above and below and discharged together from the middle, which can ensure the overall smoothness of the water flow and guarantee the flow rate;

[0017] 3. The design of the penetration holes facilitates the air to move backward after passing through the air-cooling component, ensures the smoothness of the air, and improves the cooling effect;

Detailed implementation manners

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0031] Detailed implementation manner one: In combination with Figures 1-9As shown in the figure, an engine air compression device includes: an air inlet end 1 and an air outlet end 2; the air inlet end 1 and the air outlet end 2 are arranged opposite to each other, and a water cooling component 3 and an air cooling component 4 are respectively provided therebetween. Both ends of the water cooling component 3 and the air cooling component 4 are communicated with the air inlet end 1 and the air outlet end 2 respectively. An adjusting device 5 for channel switching is provided inside the air inlet end 1. The air inlet end 1 is communicated with the air outlet of the turbocharger, and the air outlet end 2 is communicated with the engine. According to the driving state of the vehicle, the incoming high-temperature gas can be cooled by air or liquid, and in the case of extreme driving, simultaneous operation can be achieved, reducing the working burden of a single channel and greatly ensuring the combustion efficiency during the actual operation of the engine.

[0032] Preferred embodiment, in combination with Figure 4 As shown in the figure, two groups of ventilation openings 101 are respectively provided inside the air inlet end 1. Each group is composed of a plurality of ventilation openings 101 arranged in the height direction. Each ventilation opening 101 is arranged at equal intervals in the height direction, and the height direction between the two groups of ventilation openings 101 is arranged in a staggered manner, that is, the relative heights are different, so as to facilitate the adjusting device 5 to switch channels.

[0033] Preferred embodiment, in combination with Figure 3 As shown in the figure, the adjusting device 5 includes a telescopic member 501 and a switching plate 502; the telescopic member 501 adopts a small hydraulic cylinder or an electric push rod structure and is fixed above the air inlet end 1; an air inlet 503 adapted to the ventilation opening 101 is provided on the switching plate 502. The switching plate 502 is slidably connected to the air inlet end 1 and is connected to the telescopic member 501 above. When the right air inlet 503 is aligned with each air cooling channel 401, the air inlet 503 on the left completely blocks the air inlet of the water cooling channel 301. When switching is required, the telescopic member 501 pulls the switching plate 502 upward, then the gap between the right air inlet and the right ventilation opening gradually decreases, and the left side is gradually opened, so that the channel can be switched, and the situation where both are opened at the same time for a certain space can be satisfied.

[0034] Preferred embodiment, in combination with Figure 3 and Figure 6 As shown in the figure, the water cooling component 3 includes a water cooling channel 301 and a box plate 302; both ends of a plurality of water cooling channels 301 and the box plate 302 are fixedly connected to the air inlet end 1 and the air outlet end 2 respectively. The box plate 302 wraps a plurality of water cooling channels 301 therein, and a plurality of water cooling channels 301 divide the interior of the box plate 302 into a plurality of flow channels 303, and the upper and lower adjacent flow channels 303 are in a communicating state. Two water inlet pipes 304 are symmetrically provided on the left side of the box plate 302, and a water outlet pipe 305 is provided in the middle on the right side. The coolant is in a continuously bent movement mode in the flow channel 303 to keep the water path unobstructed. At the same time, in the form of simultaneous liquid inlet from above and below, continuous liquid supply can be maintained, avoiding the problem of subsequent water temperature rise caused by single-direction liquid supply and reducing the cooling effect.

[0035] Preferred embodiment, in combination with Figures 3-7 As shown, there are penetration holes 306 on the box plate 302 between two adjacent water cooling channels 301, occupying a part of the space of the flow channel 303, and leaving an outlet for the air flow of the air cooling component 4, ensuring the smoothness of the air flow.

[0036] Preferred embodiment, in combination with Figure 5 As shown, a plurality of flow dividing plates 307 are evenly arranged inside the penetration hole 306, which can divide and guide the passing air flow, making the discharged air flow more uniform.

[0037] Preferred embodiment, in combination with Figure 2 As shown, the air cooling component 4 includes an air cooling channel 401 and heat dissipation fins 402; both ends of a plurality of air cooling channels 401 are fixedly connected to the air inlet end 1 and the air outlet end 2 respectively, and heat dissipation fins 402 are integrally formed above each air cooling channel 401. By means of casting, welding, etc., the heat conduction efficiency can be effectively guaranteed. At the same time, the heat dissipation fins 402 adopt triangular extension pieces 404, which can effectively increase the contact area with the air flow and improve the heat dissipation efficiency.

[0038] After long-term use, dust and other sundries are likely to adhere to the surface of the extension piece 404, affecting heat dissipation. For this reason, the heat dissipation fins 402 are set in a detachable connection mode. Specifically, in combination with Figure 5 and Figure 8 As shown, the heat dissipation fins 402 include a bottom plate 403 and extension pieces 404; at both ends of the upper surface of the air cooling channel 401, a rectangular sliding groove is opened on the air inlet end 1 and the air outlet end 2 respectively. Both ends of the bottom plate 403 are slidably connected to the sliding grooves. At the same time, there is a pressing plate for fixing on the air inlet end 1 and the air outlet end 2 to achieve positioning, and a plurality of extension pieces 404 are fixedly connected to the bottom plate 403 together. The structure of the extension pieces 404 forms a triangular air duct, greatly increasing the contact area with the air flow.

[0039] Preferred embodiment, in combination with Figure 8 As shown, a liquid storage tank 405 is provided below the bottom plate 403. During installation, by pre-applying a heat conduction medium such as silicone grease in the liquid storage tank 405, after loading, the connection tightness between the bottom plate 403 and the air cooling channel 401 can be greatly improved, ensuring the heat conduction efficiency.

[0040] Preferred embodiment, in combination with Figure 9 As shown, a plurality of flow stabilizing channels 6 are provided inside both the water cooling channel 301 and the air cooling channel 401. The flow stabilizing channels 6 are trapezoidal structures, and air discharge holes 601 are sequentially arranged in the middle of the flow stabilizing channels 6, which can play a role in shunting the movement when high-temperature and high-pressure air flows through, and the design of the air discharge holes 601 has a certain communication and mixing effect, ensuring the stability of the air flow cooling effect.

[0041] Experimental Example: One traditional air-cooled intercooler and one water-cooled intercooler were selected, designated as Comparison 1 and Comparison 2 respectively, and this device was used as Comparison 3. Each intercooler was installed on a sedan equipped with a turbocharged engine, and corresponding data acquisition devices were arranged, such as intake temperature sensors, pressure sensors, fuel consumption meters, and engine output power measurement equipment. The test conditions were as follows: idle state (0 km / h); low-speed urban driving (30 km / h); high-speed driving (120 km / h); extreme high-temperature environment (ambient temperature 40°C, full-load operation), and the test indicators were as follows: intake temperature stability; change in engine output power; fuel consumption rate; energy consumption of the cooling system. After testing, the experimental results are as follows:

[0042]

[0043] It can be seen from the comparison that this device shows significant advantages in multiple aspects such as temperature control stability, improvement of engine output power, improvement of fuel economy, and optimization of cooling energy consumption. This not only improves the overall performance of the vehicle but also enhances its ability to adapt to different working conditions, with high practical value and market competitiveness. At the same time, the overall structure adopts a rectangular box design, which is roughly the same as the existing intercooler structure. Through simple adjustment, it can meet the installation requirements of most vehicles, with good general applicability. Moreover, within a limited space, through structural design, the overall use function is effectively improved to meet the air flow cooling under different working conditions, with strong adaptability.
