They usually have many advantages such as strong acceleration ability, high-performance engines, streamlined bodies and lightweight design. Based on their own shape and the demand for racing attributes, high-performance models with low streamlined bodies usually have small front space and cannot use large radiators. In addition, compared with traditional models, high-performance models with low streamlined bodies only have openings on the front bumper, with small air intake area and poor radiator efficiency. The exhaust gas after the radiator is used is easy to form a vortex inside the vehicle, causing large wind resistance and wind noise, and high energy consumption. Utility Model Content

[0003] In view of this, the utility model aims to provide a vehicle front end heat dissipation structure to improve its heat dissipation effect and effectively reduce wind resistance and fuel consumption.

[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0005] A vehicle front end heat dissipation structure comprises an air inlet guide structure arranged between a radiator module and a front bumper, and an air outlet guide structure arranged between the radiator module and a front hood;

[0006] The air inlet guide structure is arranged corresponding to the air inlet on the front bumper, and forms an air inlet channel between the air inlet and the radiator module;

[0007] The air outlet guide structure is arranged corresponding to the air outlet arranged on the front cover, and an air outlet channel is formed between the radiator module and the air outlet.

[0008] Furthermore, the air inlet guide structure includes an air inlet guide cover arranged between the radiator module and the front bumper, and the air inlet channel is formed in the air inlet guide cover.

[0009] Furthermore, one end of the air inlet deflector is fixedly connected to the radiator module, the other end of the air inlet deflector is overlapped on the front bumper, and a first sealing structure is provided between the air inlet deflector and the front bumper.

[0010] Furthermore, the air outlet guide structure includes an air outlet guide cover arranged between the radiator module and the front cover, and the air outlet channel is formed in the air outlet guide cover.

[0011] Furthermore, one end of the air outlet deflector is fixedly connected to the radiator module, the other end of the air outlet deflector is overlapped on the front cover, and a second sealing structure is provided between the air outlet deflector and the front cover.

[0012] Further, the radiator module includes a radiator and a cooling fan connected to one side of the radiator; and / or,

[0013] Viewed from the left and right directions of the entire vehicle, the radiator module is arranged to be inclined forward from bottom to top.

[0014] Furthermore, the air inlet channel has a converging section with a gradually decreasing air inlet cross-section along the air inlet direction.

[0015] Furthermore, the air inlet channel and / or the air outlet channel has a streamlined structure; and / or,

[0016] At least one of the air inlet and the air outlet is provided with a grille.

[0017] Further, only one air inlet channel is formed in the air inlet guide structure; and / or,

[0018] Along the wind direction, the rear end of the air outlet channel branches into a plurality of air outlet branch channels, and the air outlets are a plurality of air outlets connected to the air outlet branch channels in a one-to-one correspondence.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] The vehicle front end heat dissipation structure described in the utility model can guide external airflow to flow through the radiator by arranging an air inlet guide structure between the radiator module and the front bumper, thereby improving the heat dissipation efficiency of the radiator; and an air outlet guide structure is arranged between the radiator module and the front hood, so that the exhaust gas used by the radiator module can be discharged out of the vehicle, which can effectively prevent the used exhaust gas from forming a vortex inside the vehicle, which is beneficial to reducing driving wind resistance, reducing fuel consumption, and improving the overall performance of the vehicle.

[0021] In addition, the air inlet guide structure includes an air inlet guide cover arranged between the radiator module and the front bumper, which has a simple structure and is easy to design and implement. One end of the air inlet guide cover is overlapped on the front bumper, and a first sealing structure is arranged between the air inlet guide cover and the front bumper, which can improve the airtightness of the air inlet channel, facilitate the airflow to fully flow to the radiator module, and further improve the heat dissipation effect of the radiator module.

[0022] Secondly, the air outlet guide structure includes an air outlet guide cover arranged between the radiator module and the front hood, which has a simple structure and is easy to design and implement.

[0023] In addition, from the left and right direction of the vehicle, the radiator module is tilted forward from bottom to top, which is conducive to reducing the space occupied by the front end heat dissipation structure of the vehicle as a whole. By providing a gathering section with a gradually smaller air inlet cross-section along the air inlet direction in the air inlet channel, it is conducive to allowing the external discrete and low-speed airflow to pass through the gathering section to gather and accelerate before reaching the radiator, which can improve the heat dissipation efficiency of the radiator.

[0024] The air inlet and / or air outlet are streamlined to reduce wind resistance and wind noise, and increase downforce at the front of the vehicle; and by providing a grille at at least one of the air inlet and the air outlet, foreign matter can be prevented from entering the air inlet or air outlet. By branching a plurality of outlet branches at the rear end of the outlet, the turbulent airflow after the radiator is used can be effectively divided, so that the exhaust gas is discharged out of the vehicle more quickly, thereby greatly reducing driving wind resistance and wind noise.

[0043] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0044] In the description of the present utility model, it should be noted that the directional words such as "up, down, left, right, front, and back" used in the present embodiment are defined based on the up-down direction, left-right direction, and front-back direction of the automobile. Among them, the up-down direction of the automobile is also the height direction of the automobile (Z direction), the front-back direction of the automobile is also the length direction of the automobile (X direction), and the left-right direction of the automobile is also the width direction of the automobile (Y direction). In addition, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0045] In addition, in the description of the present invention, unless otherwise clearly defined, the terms "installation", "connection", "connection", and "connector" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] In view of the prior art, high-performance vehicles with a low streamlined body are only provided with an opening on the front bumper 3, with a small air inlet area and low heat dissipation efficiency, which makes it difficult to meet the heat dissipation needs of the vehicle. At the same time, the exhaust gas after the radiator 101 is used is easy to form a vortex inside the vehicle, causing large wind resistance and wind noise, and high energy consumption. For this reason, this embodiment specifically proposes a new type of vehicle front end heat dissipation structure, which is suitable for high-performance vehicles with a low streamlined body. The vehicle front end heat dissipation structure includes an air inlet guide structure arranged between the radiator module 1 and the front bumper 3, and an air outlet guide structure arranged between the radiator module 1 and the front hood 4.

[0048] The air inlet guide structure corresponds to the air inlet on the front bumper 3, and forms an air inlet channel between the air inlet and the radiator module 1. The air outlet guide structure corresponds to the air outlet 401 on the front hood 4, and forms an air outlet channel between the radiator module 1 and the air outlet 401.

[0049] The vehicle front end heat dissipation structure of this embodiment can guide the external airflow to flow through the radiator 101 by setting an air inlet guide structure between the radiator module 1 and the front bumper 3, thereby improving the heat dissipation efficiency of the radiator 101. The air outlet guide structure is set between the radiator module 1 and the front hood 4, so that the waste gas after use by the radiator module 1 can be discharged from the vehicle, which can effectively prevent the used waste gas from forming a vortex inside the vehicle, reduce the windward area of ​​the vehicle, and help reduce driving wind resistance, reduce fuel consumption, and improve the overall performance of the vehicle.

[0050] Based on the above overall introduction, an exemplary structure of the vehicle front end heat dissipation structure of this embodiment is referred to as Figure 1 and Figure 2 As shown in, where, without affecting the full disclosure of this embodiment, Figure 1 and Figure 2 Only the approximate positional relationship between the front bumper 3 and the front hood 4 is shown in the figure, and the specific structure thereof can refer to the prior art. Figure 3 and Figure 4As shown in , the heat sink module 1 of this embodiment includes a heat sink 101 and a heat sink fan 102 connected to one side of the heat sink 101 .

[0051] The ventilation area of ​​the cooling fan 102 is larger than that of the radiator 101. Therefore, in order to achieve a better cooling effect, the air inlet guide structure and the air outlet guide structure of this embodiment are both connected to the cooling fan 102. In addition, based on the positional relationship between the front hood 4 and the front bumper 3, as a preferred embodiment, Figure 1 and Figure 2 As shown in , from the left and right direction of the vehicle, the radiator module 1 is arranged forward from bottom to top. Such arrangement is conducive to reducing the occupied space of the entire front end heat dissipation structure of the vehicle on the vehicle.

[0052] Furthermore, the present invention does not involve any improvement to the radiator module 1, therefore, the radiator 101 and the cooling fan 102, as well as the positional connection relationship between the two, can refer to the radiator module 1 commonly used in existing vehicles, and will not be described in detail here. Figure 5 , Figure 6 and Figure 2 As shown in the figure, the air inlet guide structure of this embodiment includes an air inlet guide cover 2 disposed between the radiator module 1 and the front bumper 3, and an air inlet channel is formed in the air inlet guide cover 2. By making the air inlet guide structure include the air inlet guide cover 2 disposed between the radiator module 1 and the front bumper 3, the structure is simple and easy to design and implement.

[0053] Among them, as a preferred embodiment, combined with Figure 5 and Figure 6 As shown in , only one air inlet channel is formed in the air inlet guide structure, so as to facilitate the external airflow to flow to the heat sink module 1 as quickly as possible, and also facilitate processing and manufacturing. It is understandable that in addition to forming only one air inlet channel in the air inlet guide structure, it is also feasible to form multiple air inlet channels in the air inlet guide structure.

[0054] In addition, as a further embodiment, one end of the air inlet deflector 2 is fixedly connected to the radiator module 1, and the other end of the air inlet deflector 2 is overlapped on the front bumper 3, and a first sealing structure is provided between the air inlet deflector 2 and the front bumper 3. Figure 1 and Figure 2 As shown in , in the front-to-rear direction of the vehicle, the front end of the air inlet deflector 2 is overlapped on the front bumper 3, and the rear end thereof is installed on the cooling fan 102. In addition, the first sealing structure can be a sealing strip sandwiched between the air inlet deflector 2 and the front bumper 3, and the sealing strip can be made of sponge.

[0055] In addition, during specific implementation, the rear end of the air inlet shroud 2 can be screwed to the cooling fan 102, and, in order to facilitate the connection between the air inlet shroud 2 and the cooling fan 102, an outer flange or a welding connection ear can be designed at the rear end of the air inlet shroud 2, so as to be screwed to the cooling fan 102 through the outer flange or the connection ear. Of course, in addition to screwing the rear end of the air inlet shroud 2 to the cooling fan 102, it can also be installed on the cooling fan 102 by other conventional methods such as snap-on.

[0056] In this embodiment, the cooling fan 102 is located behind the radiator 101. Figure 5 and Figure 6 As shown in FIG, a avoidance opening 201 is provided at the rear end of the air inlet deflector 2 and is arranged to penetrate along the left and right directions thereof, and the radiator 101 is inserted into the air inlet deflector 2 through the avoidance opening 201. Such a configuration is not only conducive to the connection between the air inlet deflector 2 and the cooling fan 102, but also enables the airflow in the air inlet channel to fully flow through the radiator 101, thereby improving the heat dissipation effect of the front heat dissipation structure of the vehicle.

[0057] Combination Figure 5 and Figure 6 As shown in , as a preferred embodiment, the air inlet channel has a streamlined structure, wherein the streamlined structure means that its edge is a smooth transition surface without large undulations and sharp edges and corners. When the streamlined structure moves relative to the airflow, the airflow on its surface can maintain a good laminar state, reduce the generation of turbulence and vortices, and thus significantly reduce wind resistance and friction resistance. In addition, there can be many types of streamlined structures, such as ellipsoidal, teardrop-shaped, etc.

[0058] As a further embodiment, the air inlet channel has a gathering section 2a with a gradually decreasing air inlet cross section along the air inlet direction. This arrangement is conducive to making the external discrete and low-speed airflow gather and accelerate through the air inlet guide cover 2 before reaching the radiator 101, which can improve the heat dissipation efficiency of the radiator 101. In addition, in order to prevent foreign matter from entering the air inlet duct, such as Figure 1 and Figure 2 As shown in FIG. 1 , a grille 6 is provided at the air inlet, which refers to a parallel, mesh grille bar barrier made of metal bars.

[0059] Combination Figures 7 to 9As shown in , as a preferred embodiment, the air outlet guide structure of this embodiment includes an air outlet guide cover 5 provided between the radiator module 1 and the front hood 4, and an air outlet channel is formed in the air outlet guide cover 5. And, as a further embodiment, similar to the above-mentioned air inlet duct, the air outlet channel also has a streamlined structure. The air outlet guide structure of this embodiment includes an air outlet guide cover 5, which has a simple structure and is easy to design and implement. If the air outlet channel is set to a streamlined structure, the air flow on its surface can maintain a good laminar state, reduce the generation of turbulence and vortices, and thus significantly reduce wind resistance and friction resistance.

[0060] Combination Figure 1 and Figure 2 As shown in , as a preferred embodiment, one end of the air outlet shroud 5 is fixedly connected to the radiator module 1, and the other end of the air outlet shroud 5 is overlapped on the front cover 4, and a second sealing structure is provided between the air outlet shroud 5 and the front cover 4. Figure 1 and Figure 2 As shown in , in the vertical direction of the vehicle, the upper end of the air outlet shroud 5 is overlapped on the front hood 4, and the lower end thereof is mounted on the cooling fan 102. In addition, the second sealing structure can be specifically a sealing strip sandwiched between the air outlet shroud 5 and the front hood 4, and the sealing strip can be specifically made of sponge.

[0061] In addition, during specific implementation, the lower end of the air outlet deflector 5 can be screwed to the cooling fan 102, and in order to facilitate the connection between the air inlet deflector 2 and the cooling fan 102, an outer flange or a connecting ear can be designed at the lower end of the air outlet deflector 5, so as to be screwed to the cooling fan 102 through the outer flange or the connecting ear. Of course, in addition to screwing the lower end of the air outlet deflector 5 to the cooling fan 102, it can also be installed on the cooling fan 102 by other conventional methods such as snap-on. Thus, by setting the first sealing structure and the second sealing structure, a sealed passage from air inlet to air outlet can be formed between the front bumper 3 and the front hood 4, which can not only help improve the heat dissipation efficiency of the radiator 101, but also effectively avoid the exhaust gas used by the radiator 101 from overflowing and forming a vortex inside the vehicle, thereby reducing wind resistance and reducing fuel consumption.

[0062] In this embodiment, as a further implementation method, along the wind direction, the rear end of the air outlet channel branches out multiple outlet branches 5a, and the exhaust port 401 is a plurality of outlet branches 5a that are connected to each outlet branch channel 5a one by one. By branching out multiple outlet branches 5a at the rear end of the air outlet channel, the turbulent airflow after the radiator 101 is used can be effectively divided, so that the exhaust gas is discharged out of the vehicle more quickly, thereby greatly reducing the driving wind resistance and wind noise. Figure 1 , Figure 7 and Fig. 9As shown in FIG. 1 , as a specific embodiment, in this embodiment, along the wind direction, the rear end of the air outlet channel branches into two air outlet branch channels 5 a.

[0063] And, combined with Figures 7 to 9 As shown in FIG. 1 , as a preferred embodiment, the air outlet guide cover 5 includes an integrally formed top plate 501, a bottom plate 502, a side plate 503 connected between the top plate 501 and the bottom plate 502, and a partition plate 504 disposed between the top plate 501 and the bottom plate 502. The partition plate 504 separates the air outlet channel into two air outlet branch channels 5a. In addition, in order to realize a streamlined structure of the air outlet channel, as shown in FIG. Figure 7 As shown in FIG. 5 , the partition 504 is in a “V” shape and includes two partition bodies connected in a smooth transition.

[0064] In addition, if Figure 8 As shown in the figure, the top plate 501 and the bottom plate 502 are arc-shaped with the middle part protruding into the air outlet guide cover to form a gathering part. As a result, the exhaust gas used by the radiator module 1 can be gathered in this part and then discharged through the exhaust port 401 at an accelerated speed. In addition, in order to prevent foreign matter from entering the exhaust port 401, as a further embodiment, a grille 6 not shown in the figure is provided at the exhaust port of the front hood 4.

[0065] Here, it should be mentioned that in addition to the two branch air outlet channels 5a branched out at the rear end of the air outlet channel as mentioned above, three, four or other numbers of branch air outlet channels 5a may be branched out at the rear end of the air outlet channel, and even no branch air outlet channels 5a may be branched out.

[0066] The front-end heat dissipation structure of the vehicle of this embodiment adopts the above structure, so that the airflow enters the vehicle from the air inlet, passes through the air inlet deflector 2, the radiator module 1 and the air outlet deflector 5, and then is discharged from the vehicle from the air outlet 401. The air inlet deflector 2 can not only gather and accelerate the external discrete and low-speed airflow to reach the radiator 101, thereby improving the heat dissipation efficiency of the radiator 101. Moreover, it can also prevent the exhaust gas after the radiator 101 is used from forming a vortex inside the vehicle, reducing the frontal area of ​​the vehicle, thereby reducing wind resistance, wind noise, fuel consumption, and improving the downforce at the front of the vehicle and the control stability of the vehicle.

[0067] In addition, the present embodiment also relates to a vehicle, in which the vehicle front end heat dissipation structure as described above is provided.

[0068] The vehicle of this embodiment, by providing the above-mentioned vehicle front end heat dissipation structure, can not only have a good heat dissipation effect, but also effectively increase the downforce at the front position of the vehicle, thereby improving the vehicle's handling stability.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
