Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a side-mounted intercooler air duct system and a vehicle. Background Technology

[0002] An intercooler is a device used in a turbocharger system to reduce intake air temperature. A side-mounted intercooler refers to an intercooler layout where the intercooler is positioned laterally on either side of the traditional cooling module. As the primary heat exchanger, the airflow design of the side-mounted intercooler is crucial for its performance and the overall vehicle thermal management. In traditional gasoline-powered vehicles, the relatively large opening area of ​​the front grille effectively ensures sufficient airflow for the side-mounted intercooler. Range-extended vehicles, due to design considerations, have eliminated the opening above the front grille, making the lower part of the grille the primary opening area. This inevitably impacts the airflow to the side-mounted intercooler, particularly the upper area, with most airflow exiting directly to the lower part, thus affecting its cooling performance.

[0003] Therefore, improving the heat dissipation performance of the side-mounted intercooler in extended-range vehicles, where the area below the front grille is an opening, becomes a technical problem that needs to be solved. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a side-mounted intercooler air guide system and vehicle, which can help improve the heat dissipation performance of the side-mounted intercooler when the area below the front grille in a range-extended vehicle is an opening area.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a side-mounted intercooler air guide system, comprising: a front air guide shroud disposed at the front end of the side-mounted intercooler and having an air guide channel;

[0006] The air deflector, which can be driven to rotate and locked, is installed in the front air deflector shroud to guide the cooling air portion of the air deflector channel to the upper air intake area of ​​the side-mounted intercooler when it is within a set angle range.

[0007] Furthermore, the air guide plate closes the air guide channel when it is at a set angle position.

[0008] Furthermore, the upper part of the inner wall of the front air guide shroud is provided with a downwardly extending upper baffle, and the lower part of the inner wall of the front air guide shroud is provided with an upwardly extending lower baffle; when the air guide channel is in the closed state, the upper and lower ends of the air guide plate respectively abut against the upper baffle and the lower baffle.

[0009] Furthermore, the rotation axis of the air guide plate is arranged laterally along the front air guide shroud.

[0010] Furthermore, the rotation axis of the air guide plate is located at the middle position of the air guide channel in the vertical direction.

[0011] Furthermore, it also includes a drive motor with an output shaft locking function located outside the front air guide cover. The drive motor is connected to the air guide plate for driving the rotation of the air guide plate.

[0012] Furthermore, the front air guide shroud has a flared section in the middle of its front-rear direction that flares outward and upward.

[0013] Furthermore, it also includes a rear air guide shroud and a front wheel cover. The rear air guide shroud is sealed to the rear end face of the side-mounted intercooler and extends rearward to the front wheel cover. The front wheel cover is provided with an exhaust port opposite to the rear air guide shroud.

[0014] Furthermore, the exhaust vent is a grille vent, which is arranged at an angle from front to back and downward.

[0015] A vehicle including an airflow system for a side-mounted intercooler as described above.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The airflow system and vehicle for the side-mounted intercooler provided by this utility model can improve the heat dissipation performance of the side-mounted intercooler when the area below the front grille is used as an opening in a range-extended vehicle. Specifically, the front air hood with airflow channels effectively gathers airflow, while the air deflector guides some of the air from the front of the airflow channels to the upper air intake area of ​​the side-mounted intercooler. This effectively ensures the airflow volume at the top of the side-mounted intercooler, improves the uniformity of airflow, and to some extent reduces the problem of insufficient airflow at the top of the intercooler caused by the removal of the opening above the front grille. This, in turn, improves the heat dissipation performance of the side-mounted intercooler and makes it more suitable for use in range-extended vehicles where the area below the front grille is used as an opening.

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only for illustrating the basic concept of this utility model. Unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0024] Please see Figure 1-3 This embodiment discloses an airflow guiding system for a side-mounted intercooler, including: a front airflow guide shroud 2 disposed at the front end of the side-mounted intercooler 1 and having an airflow guiding channel 2a; and an airflow guide plate 3, which is rotatable and lockable within the front airflow guide shroud 2, used to guide a portion of the cooling air from the airflow guiding channel 2a to the upper air intake area of ​​the side-mounted intercooler 1 when within a set angle range. It is understood that the "front end" of the side-mounted intercooler 1 refers to the end near the front of the vehicle; the front end of the front airflow guide shroud 2 is positioned opposite the front grille 7 of the vehicle to receive the cooling air transmitted from the front grille. The airflow guide plate 3 is generally controlled to rotate by a motor. See also... Figure 1 , Figure 1 The dotted line indicates the position of the air guide plate 3 when it is in a certain tilted state. The cooling air coming from the front of the air guide channel 2a, under the guidance of the air guide plate 3, can guide a portion of the airflow to the upper air intake area of ​​the side-mounted intercooler 1, thereby increasing the airflow to the upper air intake area of ​​the side-mounted intercooler 1. Preferably, the air guide plate 3 is initially in a vertical position, which allows it to... Figure 1 The angle position is adjusted between 0 and 90 degrees counterclockwise from the perspective shown. In actual use, the air guide plate 3 starts in a vertical position, and then... Figure 1When rotated counterclockwise by 50-80 degrees from the perspective shown, the airflow guidance effect is good. Here, the front air guide shroud 2 has a cylindrical structure, and the interior of the front air guide shroud 2 forms an air guide channel 2a. The air guide system of the side-mounted intercooler provided above can help improve the heat dissipation performance of the side-mounted intercooler when the area below the front grille is used as an opening in the range-extended vehicle. Specifically, the front air guide shroud 2 with the air guide channel 2a can effectively gather airflow. At the same time, the air guide plate 3 can effectively guide the airflow in front of the air guide channel 2a to the upper air intake area of ​​the side-mounted intercooler 2, thereby effectively ensuring the air intake volume of the upper part of the side-mounted intercooler 1, improving the air intake uniformity of the side-mounted intercooler 1, and to a certain extent overcoming the problem of insufficient air intake volume in the upper part of the intercooler 1 caused by the removal of the opening above the front grille. This can improve the heat dissipation performance of the side-mounted intercooler 1 and better adapt to the use of the area below the front grille in the range-extended vehicle. Meanwhile, in this structural design, the overall air intake of the side-mounted intercooler 1 can be controlled by adjusting the tilt angle of the air guide plate 3, which can help to better adapt to different operating conditions of the car.

[0025] In this embodiment, the air guide plate 3 closes the air guide channel 2a when it is at a set angle position. Specifically, the air guide plate 3 closes the air guide channel 2a when it rotates to a vertical or near-vertical position. Here, "near-vertical position" means that a certain manufacturing deviation is allowed. This structural design can help improve the vehicle's overall thermal management performance. In low-temperature winter environments, the engine intake air can be kept warm by closing the air guide channel 2a. For range-extended vehicles, in pure electric mode, the vehicle's wind resistance can be reduced and the vehicle's range increased by closing the air guide channel 2a. At the same time, in this structural design, the air guide plate 3 has a simple arrangement and low manufacturing cost.

[0026] In this embodiment, the upper part of the inner wall of the front air guide shroud 2 is provided with a downwardly extending upper baffle 201, and the lower part of the inner wall of the front air guide shroud 2 is provided with an upwardly extending lower baffle 202; when the air guide channel 2a is in the closed state, the upper and lower ends of the air guide plate 3 respectively abut against the upper baffle 201 and the lower baffle 202. Specifically, the upper baffle 201 and the lower baffle 202 are integrally injection molded with the front air guide shroud 2. See Figure 1 When the air guide plate 3 is in a vertical position, the front end face of the upper part of the air guide plate 3 is in contact with the rear end face of the upper baffle 201, and the rear end face of the lower part of the air guide plate 3 is in contact with the front end face of the lower baffle 201. In this structural design, by setting the upper baffle 201 and the lower baffle 202, it is convenient to close the air guide channel 2a. At the same time, the structure is simple and has good reliability. Of course, it is understandable that the vertical length of the upper baffle 201 and the lower baffle 202 should not be too long during the design process to reduce the impact on the cross-sectional area of ​​the air guide channel 2a.

[0027] In this embodiment, the rotation axis of the air guide plate 3 is arranged laterally along the front air guide shroud 2. Here, the lateral direction of the front air guide shroud 2 corresponds to the width direction of the vehicle. By arranging the rotation axis of the air guide plate 3 laterally along the front air guide shroud 2, it is convenient to realize the rotation adjustment of the air guide plate 3, and the arrangement structure of the air guide plate 3 is simple.

[0028] In this embodiment, the rotation axis of the air guide plate 3 is located at the middle position of the air guide channel 2a in the vertical direction. By setting the rotation axis of the air guide plate 3 at the middle position of the air guide channel 2a in the vertical direction, after rotating the air guide plate 3, a portion of the cooling air can be guided from the upper surface of the air guide plate 3 to the upper air intake area of ​​the side-mounted intercooler 1, while another portion of the cooling air is blown from the lower part of the air guide plate 3 to the lower air intake area of ​​the side-mounted intercooler 1, which has a good effect on improving the heat dissipation performance of the side-mounted intercooler 1.

[0029] In this embodiment, a drive motor 4 with an output shaft locking function is also included, which is disposed outside the front air guide shroud 2. The drive motor 4 is connected to the air guide plate 3 for driving the rotation of the air guide plate 3. By using a drive motor 4 with an output shaft locking function, the position locking of the air guide plate 3 can be easily achieved. The structure is simple and the locking is reliable. Specifically, the drive motor 4 is a servo motor, which can precisely control the rotation angle of its output shaft, thereby controlling the tilt angle of the air guide plate 3. By arranging the drive motor 4 outside the front air guide shroud 2, the internal space of the front air guide shroud 2 is not occupied, which helps to ensure better air intake of the air guide channel 2a. More specifically, the drive motor 4 is fixedly installed on the outer wall of the front air guide shroud 2 on one side of the lateral direction. The output shaft of the drive motor 4 passes through the shell wall of the front air guide shroud 2 and is connected to the air guide plate 3 by means such as a spline connection. More specifically, the air guide plate 3 has a rotating shaft 301 arranged laterally along the front air guide shroud 2 in the middle of its own length direction. The output shaft of the drive motor 4 is connected to the rotating shaft 301. More specifically, the rotating shaft 301 and the air guide plate 3 are integrated into one structure. One end of the rotating shaft 301 is rotatably connected to the shell wall of the front air guide cover 2, and the other end of the rotating shaft 301 is connected to the output shaft of the drive motor 4 via a spline. By setting the rotating shaft 301, it is convenient to connect with the drive motor 4. The area of ​​the air guide plate 3 excluding the rotating shaft 301 can be designed to be relatively thinner, which facilitates lightweight design and saves material costs.

[0030] In this embodiment, the front air hood 2 has a flared section 203 that widens upwards and backwards in the middle of its front-rear direction. Here, "front-rear direction" corresponds to the length direction of the vehicle. Specifically, the front air hood 2 has a structure with a smaller front section and a larger rear section. The front and rear sections are transitioned through the flared section 203. The smaller front section better fits the opening area below the front grille, while the larger rear section can accommodate the windward shield of the side-mounted intercooler 1. More specifically, the longitudinal section of the flared section 203 is approximately trapezoidal, with "longitudinal" corresponding to the length direction of the vehicle. Both the front and rear sections of the front air hood 2 are rectangular cylindrical structures. This structural design results in a compact front air hood 2 with good airflow guidance. It facilitates better adaptation to situations where the lower area of ​​the vehicle's front grille is used as an opening area. More specifically, the rotating mounting point of the air guide plate 3 is located within the flared section 203 area. When the air guide plate 3 is tilted, the air guide plate 3 can form a better matching relationship with the flared section 203 that flares out to the rear and upward, and the air guide plate 3 can form an air guide channel that is arranged obliquely to the rear and upward between the upper wall of the flared section 203 and the air guide plate 3.

[0031] This embodiment also includes a rear air guide shroud 5 and a front wheel arch 6. The rear air guide shroud 5 is sealed to the rear end face of the side-mounted intercooler 1 and extends rearward to the front wheel arch 6. The front wheel arch 6 is provided with an exhaust port 601 opposite to the rear air guide shroud 5. Specifically, the sealing connection between the rear air guide shroud 5 and the side-mounted intercooler 1 is achieved by setting a sealing strip between them. By setting the rear air guide shroud 5 and guiding the air to the front wheel arch 6, and exhausting the air through the exhaust port 601 on the front wheel arch 6, the heat dissipation efficiency of the side-mounted intercooler 1 can be further improved. Specifically, the air is guided by the rear air guide shroud 5 and directly exhausted through the exhaust port 601 on the front wheel arch 6, resulting in low exhaust resistance and increased air intake, thereby further improving the heat dissipation performance of the side-mounted intercooler 1.

[0032] More specifically, in this embodiment, the front air guide shroud 2 is sealed and connected to the front end face of the side-mounted intercooler 1. Here, the sealing and connection between the front air guide shroud 2 and the side-mounted intercooler 1 is achieved by setting a sealing strip. It can be understood that the front air guide shroud 2 completely covers the windward side of the front end of the side-mounted intercooler 1. By sealing and connecting the front air guide shroud 2 and the side-mounted intercooler 1, the amount of airflow that can escape through the gap between the front air guide shroud 2 and the side-mounted intercooler 1 can be reduced, thereby further improving the air intake efficiency of the side-mounted intercooler 1 and improving its heat dissipation performance.

[0033] In this embodiment, the exhaust vent 601 is a grille vent, which is arranged at an angle from front to rear and downward. Using a grille vent arranged at an angle from front to rear and downward reduces the risk of external dust, mud, and water entering the rear air guide shroud 5, improving reliability; at the same time, it has good structural strength and durability.

[0034] This embodiment also discloses a vehicle including an airflow system for a side-mounted intercooler as described above. The side-mounted intercooler of this vehicle has good heat dissipation performance and is suitable for use as an opening area below the front grille.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
