Description

Technical Field

[0001] The present disclosure relates to the field of heat dissipation technology, and in particular to an intercooler air guide assembly and a vehicle. Background Art

[0002] The intercooler is an important part of the turbocharger system, used to reduce the turbocharger intake temperature. The performance of the intercooler affects the performance of the turbocharger, and further affects the power and economy of the vehicle.

[0003] Common intercoolers include water-cooled and air-cooled. Water-cooled intercoolers are complex in structure and difficult to maintain. Air-cooled intercoolers are simple in structure and easy to maintain. Air-cooled intercoolers use the air blowing in the direction of the car when it is moving forward for cooling, but the cooling effect will be reduced when the car is parked or driving at low speed.

[0004] The intercooler is usually located at the front of the car, with the rest of the car behind it. Under some low-speed conditions, the airflow near the intercooler changes and may cause backflow, which will reduce the performance of the intercooler. Utility Model Content

[0005] Based on this, it is necessary to provide an intercooler air guide assembly and a vehicle to solve the problem of air flow backflow at the intercooler.

[0006] The disclosed embodiment provides an intercooler air guide assembly, which includes: an underbody guard plate; an intercooler located on the upper side of the underbody guard plate; a wheel cover connected to the underbody guard plate, the wheel cover being located on the rear side of the intercooler, and the wheel cover being provided with an opening corresponding to the intercooler; and an outlet air guide device located between the intercooler and the wheel cover, the outlet air guide device being connected to the air outlet of the intercooler and the opening of the wheel cover, the shape of the rear end of the outlet air guide device matching the shape of the front end of the wheel cover, and the shape of the front end of the outlet air guide device matching the shape of the rear end of the intercooler.

[0007] By setting an opening in the wheel cover and connecting the intercooler to the opening by using an outlet air guide device, the air outlet gas of the intercooler can be effectively transferred to the wheel cover, and by setting a matching relationship of the outlet air guide device, air leakage at the outlet air guide device is prevented. The intercooler air guide assembly provided in the embodiment of the present disclosure has good heat dissipation performance and avoids air flow backflow at the intercooler.

[0008] In some embodiments, the outlet air guide device includes a plurality of air guide ribs, and each of the plurality of air guide ribs is configured to gradually tilt downward in a direction from front to rear.

[0009] Such a setting ensures that the airflow in the front flows backwards, and is also beneficial for blocking the gas above to prevent backflow, which is beneficial for protecting the intercooler and improving the working performance of the intercooler.

[0010] In some embodiments, the wheel cover has an inner side and a side along the left-right direction; and the wind guide ribs are configured to gradually tilt downward in a direction from the side to the inner side.

[0011] With such an arrangement, the air guide ribs can guide the airflow obliquely downward, which is beneficial for directing the airflow to the side of the wheel arch.

[0012] In some embodiments, projections of two adjacent wind guiding ribs in a vertical plane in the front-to-back direction overlap.

[0013] Such a configuration is conducive to improving the flow guiding effect and the backflow prevention effect. Multiple air guiding ribs cooperate to protect the intercooler and ensure the heat exchange performance of the intercooler. In addition, multiple inclined air guiding ribs with overlapping projections can be arranged densely and are conducive to strengthening the structural strength of the outlet air guiding device.

[0014] In some embodiments, the outlet air guide device further includes an outer frame and reinforcing ribs, a plurality of air guide ribs are arranged in the outer frame, the reinforcing ribs and the air guide ribs are cross-arranged, and the reinforcing ribs are fixed to the outer frame and to the air guide ribs.

[0015] Such an arrangement can improve the structural stability of the outlet air guide device and ensure the normal operation of the air guide ribs during airflow changes.

[0016] In some embodiments, the outlet air guide device is riveted to the wheel housing, and the outlet air guide device is fixed to the bottom guard plate through the wheel housing.

[0017] With such arrangement, the outlet air guide device and the wheel cover are connected and then assembled to the bottom guard plate, which is easy to assemble and can ensure the connection strength; it is beneficial to ensure the coordination between the outlet air guide device and the wheel cover and can also avoid affecting the bottom guard plate.

[0018] In some embodiments, the intercooler air guide assembly also includes an inlet air guide device, which is located at the front side of the intercooler. The inlet air guide device includes an air induced draft hood and an air inlet hood. The air induced draft hood is connected to the inlet of the air inlet hood, and the air inlet hood is connected to the intercooler.

[0019] Such an arrangement can flexibly configure the inlet air guide device according to installation requirements and air intake requirements to ensure the air intake effect.

[0020] Exemplarily, the inlet of the air inlet hood is smaller than the outlet of the air inlet hood, and the inlet of the air inlet hood corresponds to the lower part of the outlet of the air inlet hood.

[0021] Such arrangement is convenient for installation and can provide sufficient air intake.

[0022] Exemplarily, the inlet of the induced draft hood is larger than the outlet of the induced draft hood.

[0023] Such arrangement can ensure sufficient air intake. In addition, the inlet air guide device forms an air flow channel similar to a trumpet shape, which can make the air flow smoothly enter the intercooler.

[0024] In some embodiments, the inlet air guide device is connected to the intercooler by bolts, and the inlet air guide device is fixed to the bottom guard plate through the intercooler; the inlet air guide device and the intercooler are matched by a sponge seal.

[0025] With such arrangement, the inlet air guide device is assembled with the intercooler and then assembled as a whole, and is located on the bottom guard plate, which is easy to assemble, ensuring the sealing performance and air intake effect, and avoiding affecting the bottom guard plate.

[0026] In some embodiments, the outlet air guide device is spaced apart from the side edge of the wheel arch.

[0027] Such an arrangement ensures that the outlet air guide device is installed reliably and is in good docking condition.

[0028] Exemplarily, the side edge of the bottom guard plate has an arc shape, and the air hood is configured to be arranged in an arc shape relative to the side edge of the bottom guard plate, and the inlet of the air hood is configured to open toward the front side and toward the side.

[0029] Such arrangement can effectively utilize the installation space and provide a larger air intake. In addition, the outlet air guide device has enough space to ensure smooth air discharge.

[0030] The disclosed embodiment also provides a car, which includes the aforementioned intercooler air guide assembly.

[0031] The automobile of the disclosed embodiment has good driving performance and can adapt to different working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] refer to Figure 1 , Figure 1 The intercooler air guide assembly of the embodiment of the present disclosure is shown. In an exemplary embodiment, the intercooler air guide assembly 100 includes an underbody guard plate 1, an intercooler 2, a wheel housing 3, and an outlet air guide device 4.

[0050] Combination Figure 3 and Figure 4 As shown, in some embodiments, the bottom guard plate 1 may be a whole body that runs through the left and right sides, and it may be an integrated structure. The intercooler air guide assembly 100 may include two wheel covers 3, namely a first wheel cover 310 and a second wheel cover 320. Figure 1 As shown, with the positive direction of the X-axis being the direction from the back to the front, the first wheel cover 310 can be called the left wheel cover, and the second wheel cover 320 can be called the right wheel cover. The wheel cover 3 is connected to the bottom guard plate 1, and the wheel cover 3 can be generally located at the rear upper part of the bottom guard plate 1, and the bottom guard plate 1 can be generally located at the front lower part of the wheel cover 3.

[0051] The intercooler 2 is located on the upper side of the bottom guard plate 1. The intercooler 2 may be connected to the bottom guard plate 1. In other embodiments, the intercooler 2 is connected to other components and then attached to or floats on the upper side of the bottom guard plate 1. Exemplarily, the intercooler air guide assembly 100 may include two intercoolers 2, namely a first intercooler 210 and a second intercooler 220. The intercooler air guide assembly 100 may include at least one intercooler 2, for example, other numbers of intercoolers 2. The wheel cover 3 is located on the rear side of the intercooler 2, and exemplarily, the first wheel cover 310 is located on the rear side of the first intercooler 210, and the second wheel cover 320 is located on the rear side of the second intercooler 220.

[0052] refer to Figure 2 In some comparative examples, there is a gap between the intercooler 2 and the wheel cover 3, especially when it comes to the layout of the intercooler 2 external pipeline, it is inconvenient to adjust the position of the intercooler 2; and the wheel cover 3 often has an arc shape, and its front end is not necessarily a flat structure, and the rear end of the intercooler 2 does not match the wheel cover 3. At high speeds, the airflow can pass through the intercooler 2 from front to back and take away a certain amount of heat. At low speeds, it is difficult for the airflow to blow through the intercooler 2, such as Figure 2As shown, the gas behind the intercooler 2, for example, the airflow on the rear upper side, may also flow back. The backflowing gas will affect the heat dissipation of the intercooler 2 and reduce the efficiency of the intercooler 2. In other comparative examples, an inlet air guide device 5 is provided on the front side of the intercooler 2, but the inlet air guide device 5 in this comparative example mainly enhances the air intake capacity of the intercooler 2.

[0053] The intercooler air guide assembly 100 provided in the embodiment of the present disclosure includes an outlet air guide device 4, and the outlet air guide device 4 is located between the intercooler 2 and the wheel cover 3. Exemplarily, the intercooler air guide assembly 100 includes two outlet air guide devices 4, namely a first outlet air guide device 410 and a second outlet air guide device 420, wherein the first outlet air guide device 410 is located between the first intercooler 210 and the first wheel cover 310, and the second outlet air guide device 420 is located between the second intercooler 220 and the second wheel cover 320.

[0054] Exemplarily, the wheel housing 3 is provided with an opening 301 corresponding to the intercooler 2. The outlet air guide device 4 is connected to the air outlet of the intercooler 2 and the opening 301 of the wheel housing 3, and can transfer the airflow at the intercooler 2 to the opening 301 and then discharge it backwards.

[0055] refer to Figure 5 and Figure 6 , the front end of the outlet air guide device 4 may be referred to as the first front end 401, and the rear end of the outlet air guide device 4 may be referred to as the first rear end 402. For example, the front end of the wheel cover 3 may be referred to as the second front end 303; the rear end of the intercooler 2 may be referred to as the second rear end.

[0056] The outlet air guide device 4 is matched and docked with the intercooler 2, or the shape of the first front end 401 is matched with the shape of the second rear end, and the first front end 401 is docked with the second rear end, which can effectively utilize the installation space and avoid air leakage. Figure 1 As shown, when the ventilation passage of the intercooler 2 is roughly rectangular, the first front end 401 can be roughly rectangular, and the first front end 401 can just cover or be slightly larger than the second rear end. When the second rear end has a convex structure, the first front end 401 can have a corresponding concave structure.

[0057] The shape of the rear end of the outlet air guide device 4 matches the shape of the front end of the wheel cover 3, or in other words, the shape of the first rear end 402 matches the shape of the second front end 303. Figure 1 As shown, based on the cross-section parallel to the XY plane, the cross-section of the second front end 303 is roughly arc-shaped, and the first rear end 402 also has a corresponding arc shape; based on the cross-section parallel to the XZ plane, the cross-section of the second front end 303 is relatively flat, but can also have a certain curvature, and the first rear end 402 is still a corresponding arc shape.

[0058] Combination Figure 4As shown, by setting an opening 301 in the wheel housing 3 and connecting the intercooler 2 to the opening 301 by using the outlet air guide device 4, the outlet gas of the intercooler 2 can be effectively transferred to the wheel housing 3, and by setting the matching relationship of the outlet air guide device 4, air leakage at the outlet air guide device 4 is prevented. The intercooler air guide assembly 100 provided in the embodiment of the present disclosure has good heat dissipation performance and avoids air flow backflow at the intercooler 2.

[0059] like Figure 5 and Figure 6 As shown, in some embodiments, the outlet air guide device 4 includes a plurality of air guide ribs 41, the cross section of the outlet air guide device 4 intersects the X-axis direction, and the plurality of air guide ribs 41 can be arranged substantially along the Z-axis direction, and the Z-axis direction can be the up-down direction. In other embodiments, the plurality of air guide ribs 41 can also be arranged in an array on the YZ plane.

[0060] Each of the plurality of air guiding ribs 41 is configured to be gradually inclined downward from the front to the rear. The air guiding rib 41 may be in the form of a thin sheet, such as Figure 5 As shown, the lower side surface 411 is lower as it moves backward along the X-axis direction. Figure 6 As shown, the upper side surface 412 is higher the closer to the front part along the X-axis direction. Each air guide rib 41 ensures that the airflow in front of it flows backward, and is also helpful to block the air above to prevent backflow, which is beneficial to protect the intercooler 2 and improve the working performance of the intercooler 2.

[0061] Combination Figure 1 As shown, among the multiple wheel covers 3 of the intercooler air guide assembly 100, along the positive direction of the X-axis, the first wheel cover 310 is the left wheel cover, more specifically, the left front wheel cover, and the second wheel cover 320 is the right wheel cover, such as the right front wheel cover. The wheel cover 3 has an inner side and a side along the left and right directions. For the first wheel cover 310, its left side along the Y-axis direction is the side side, and the right side is the inner side; for the second wheel cover 320, the right side is the side side, and the left side is the inner side. In some embodiments, the air guide rib 41 is configured to gradually tilt downward in the direction from the side side to the inner side, and the air guide rib 41 can guide the airflow obliquely downward, which is conducive to guiding the airflow to the side side of the wheel cover 3.

[0062] The air guide ribs 41 in the first outlet air guide device 410 and the air guide ribs 41 in the second outlet air guide device 420 can be symmetrically arranged. Exemplarily, the first wheel cover 310 and the second wheel cover 320 are roughly symmetrical in shape, and the openings 301 of the two can be symmetrical or designed separately. The first intercooler 210 and the second intercooler 220 can be structurally symmetrical or designed separately. The first outlet air guide device 410 and the second outlet air guide device 420 can be structurally symmetrical or designed separately.

[0063] The plurality of air guide ribs 41 may be substantially parallel or may have an angle deviation. Exemplarily, based on a cross section parallel to the XZ plane, the inclination angle of the section of the air guide rib 41 relative to the X-axis direction may be 30° to 60°, for example, 45°. Exemplarily, based on a cross section parallel to the YZ plane, the section of the air guide rib 41 may have a certain arc, and the inclination angle of the tangent at each position of the section relative to the Y-axis direction may be 10° to 45°, for example, 30°.

[0064] In some embodiments, in the projection plane parallel to the YZ plane, that is, in the vertical plane in the X-axis direction or the front-to-back direction, two adjacent air guide ribs 41 overlap in the projection along the front-to-back direction, which is beneficial to improving the air guide effect and the anti-backflow effect. Multiple air guide ribs 41 cooperate to protect the intercooler 2 and ensure the heat exchange performance of the intercooler 2. Exemplarily, multiple air guide ribs 41 cover the entire air guide channel along the X-axis direction, and the airflow in front of the air guide ribs 41 can be guided downward. In addition, the hot airflow in the front also tends to be squeezed downward; the airflow in the rear is more easily blocked, and backflow can be effectively prevented even under low-speed conditions.

[0065] In some embodiments, the outlet air guide device 4 further includes an outer frame 42, and the outer frame 42 is used to form a first front end 401 and a first rear end 402. The outer frame 42 can define an air guide channel, and a plurality of air guide ribs 41 are disposed in the outer frame 42, and the plurality of air guide ribs 41 can cover the outer frame 42.

[0066] Exemplarily, the outlet air guide device 4 further includes a reinforcing rib 43. The reinforcing rib 43 is cross-arranged with the air guide ribs 41, and the reinforcing rib 43 is fixed to the outer frame 42 and to the air guide ribs 41, which can improve the structural stability of the outlet air guide device 4 and ensure the normal operation of the air guide ribs 41 during the airflow change.

[0067] In some embodiments, the outlet air guide device 4 is riveted to the wheel housing 3, and the outlet air guide device 4 is fixed to the bottom guard plate 1 through the wheel housing 3. After the outlet air guide device 4 and the wheel housing 3 are connected, they are assembled together to the bottom guard plate 1. The intercooler air guide assembly 100 is easy to assemble and can ensure the connection strength; it is beneficial to ensure the matching relationship between the outlet air guide device 4 and the wheel housing 3, and can also avoid affecting the bottom guard plate 1.

[0068] For example, the outer frame 42 can be used to achieve riveting. The outlet air guide device 4 can be close to the wheel cover 3, or partially penetrate the opening 301. The outer frame 42 includes flanges and notches to match other components, and the flange of the first front end 401 can be connected to the intercooler 2. The outlet air guide device 4 can be an integrated structure, and the connection strength of the air guide ribs 41 and the reinforcing ribs 43 is easy to ensure.

[0069] Combination Figure 7 and Figure 8As shown, in some embodiments, the intercooler air guide assembly 100 further includes an inlet air guide device 5, which is located at the front side of the intercooler 2. The intercooler air guide assembly 100 may include two inlet air guide devices 5, namely a first inlet air guide device 510 and a second inlet air guide device 520. The first inlet air guide device 510 is located at the front side of the first intercooler 210, and the second inlet air guide device 520 is located at the front side of the second intercooler 220. The first inlet air guide device 510 and the second inlet air guide device 520 may be symmetrically arranged or designed separately.

[0070] The inlet air guide device 5 includes an air inlet cover 52 and an air inlet cover 51, which can be assembled together. The inlet of the air inlet cover 51 can be called a first inlet 511, and the outlet can be called a first outlet 512. The inlet of the air inlet cover 52 can be called a second inlet 521, and the outlet can be called a second outlet 522.

[0071] The air inlet cover 51 is connected to the intercooler 2, and specifically, the first outlet 512 is connected to the air inlet 201 of the intercooler 2. Figure 1 As shown, the shape of the rear end of the air inlet cover 51 can match the shape of the third front end 204 of the intercooler 2, for example, both are rectangular. The air inlet 201 is opened at the third front end 204. The first outlet 512 is opened at the rear end of the air inlet cover 51.

[0072] The first inlet 511 of the air inlet cover 51 is smaller than the first outlet 512 of the air inlet cover 51, and the first inlet 511 corresponds to the lower part of the first outlet 512 along the Z-axis direction. The upper part of the air inlet cover 51 can be tilted.

[0073] The air hood 52 is connected to the first inlet 511, and the second outlet 522 of the air hood 52 is connected to the first inlet 511. The second outlet 522 can be larger or smaller than the first inlet 511, or the two can cooperate to realize the airflow channel. The second inlet 521 of the air hood 52 is larger than the second outlet 522 of the air hood 52. The inlet air guide device 5 forms an airflow channel similar to a trumpet shape, which can make the airflow smoothly enter the intercooler 2.

[0074] The inlet air guide device 5 is sealed with the intercooler 2, for example, by a sponge to ensure sealing performance and air intake effect.

[0075] In some embodiments, the inlet air guide device 5 is connected to the intercooler 2 by bolts, and the inlet air guide device 5 can be assembled with the intercooler 2, for example, fixed to the bottom guard plate 1 through the intercooler 2. The inlet air guide device 5 is assembled with the intercooler 2 and then assembled to the bottom guard plate 1, which is easy to assemble and avoids affecting the bottom guard plate 1.

[0076] The wheel cover 3 can be connected to the bottom guard plate 1 by bolts. The front edge of the wheel cover 3 can be overlapped on the bottom guard plate 1.

[0077] Combination Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the outlet air guide device 4 is spaced apart from the side edge of the wheel cover 3, and the side edge is called the first side edge 302. The opening 301 is spaced apart from the first side edge 302, and the outlet air guide device 4 has enough space to ensure smooth air flow.

[0078] The side edge of the bottom guard plate 1 can be referred to as the second side edge 101, and the second side edge 101 has an arc shape. The air ducting cover 52 is configured as follows: relative to the second side edge 101 of the bottom guard plate 1, the second inlet 521 is configured to be opened toward the front side and toward the side. The inlet air guide device 5 can effectively utilize the installation space and provide a larger air intake volume. The intercooler air guide assembly 100 has a compact structure, and the intercooler 2 has good heat dissipation performance.

[0079] refer to Fig. 9 The embodiment of the present disclosure also provides a car 1000, which includes the aforementioned intercooler air guide assembly 100. The car 1000 has good driving performance and can adapt to different working conditions.

[0080] Combination Figure 1 As shown, the intercooler 2 has a first interface 202 and a second interface 203, the first interface 202 is connected to the second interface 203, and is thermally coupled to the air inlet 201. The automobile 1000 also includes a turbocharger 200, and the first interface 202 of the intercooler 2 is connected to the turbocharger 200. The automobile 1000 also includes an engine 300, and the engine 300 is connected to the second interface 203 of the intercooler 2. The gas compressed by the turbocharger 200 is cooled by the intercooler 2 and can be input into the engine 300. The intercooler 2 has good cooling performance, which ensures the working performance of the engine 300.

[0081] The engine 300 can be used to drive the wheels 400 , which are located in the wheel housing 3 .
