Description

Technical Field

[0001] The utility model relates to the field of automobiles, and more specifically, to an automobile engine compartment and a new energy vehicle. Background Art

[0002] One of the existing heat dissipation methods for the front engine compartment of an automobile is fan heat dissipation. The fan takes away the heat generated by heat-generating components such as the engine, battery, and motor through air flow. Especially for new energy vehicles, since a large number of electrical components, such as motors and inverters, are integrated in the front engine compartment of new energy vehicles, the spatial layout of the entire front engine compartment is very compact, resulting in the backflow of hot air in front of the condenser, affecting the normal operation of the condenser. Moreover, when the hot air flows back to the rear of the condenser, it will also cause a decrease in the heat dissipation efficiency of the radiator fan at the rear of the condenser. In addition, under extreme working conditions, the intake air volume in the front engine compartment of the vehicle is insufficient, and the insufficient intake air volume directly restricts the requirement for the normal intake air volume of the condenser, resulting in limited condenser function and inability to operate normally.

[0043] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0044] The engine compartment thermal management of new energy vehicles is crucial to ensure the efficient operation of the vehicles. Currently, one of the heat dissipation measures for the engine compartment is mainly to optimize the layout of the radiator and the cooling fan, increase the heat dissipation area and raise the wind speed to accelerate the discharge of the heat in the engine compartment. Although these measures have significantly improved the heat dissipation efficiency, the overall heat dissipation efficiency is still not high. Analyzing the reasons, firstly, a large number of electronic components are arranged in the engine compartment, resulting in a compact space layout. The hot air generated flows back in front of the condenser, affecting the heat dissipation efficiency. Secondly, the intake volume of cold air in the engine compartment is insufficient, causing the condenser to malfunction and further limiting the heat dissipation effect.

[0045] In view of this, please refer to Figures 1 to 9 , the engine compartment of a motor vehicle and the new energy vehicle provided in the embodiments of the present utility model can solve the above problems. At the same time, the engine compartment of a motor vehicle provided in the embodiments of the present utility model can be used for various motor vehicles, including fuel vehicles, new energy vehicles (electric vehicles, hybrid electric vehicles, fuel cell vehicles), etc. During use, only adaptive adjustments need to be made according to the layout of the motor vehicle. In this embodiment, a new energy vehicle is taken as an example for illustration, and it is not limited that the engine compartment of the motor vehicle is only applicable to new energy vehicles.

[0046] Refer to Figure 1 , the embodiments of the present utility model provide an engine compartment of a motor vehicle and a new energy vehicle, which will be described in detail hereinafter.

[0047] The engine compartment of the motor vehicle includes an engine compartment frame 5 and various devices / components / devices / parts arranged or connected inside or on the engine compartment frame 5. Some of these devices / components / devices / parts generate heat, and the heat exchanges with the air in the engine compartment frame 5 to form hot air. In this embodiment, a condenser 4 is arranged inside the engine compartment frame 5. Through the condenser 4, heat exchange is carried out on the hot air in the engine compartment frame 5 to achieve heat dissipation and temperature reduction of each device in the engine compartment frame 5. After heat exchange by the condenser 4, the temperature of the air on one side of the heat pipe of the condenser 4 will rise. However, in the natural state, the hot air on the heat pipe side of the condenser 4 will not all disperse outward, but a part of the hot air will flow back from the left and right sides of the condenser 4 to the rear of the condenser 4, thus affecting the condenser 4. Therefore, in this embodiment, air guiding plates 1 are arranged on the left and right sides of the condenser 4 to block the backflow of the hot air.

[0048] In addition, an engine compartment mudguard 2 is arranged on the engine compartment frame 5, and a ventilation channel 20 is arranged on the engine compartment mudguard 2. The ventilation channel 20 is communicated with the inside of the engine compartment frame 5, thus solving the problem of insufficient air intake in the engine compartment under extreme working conditions, and also solving the problem that the condenser 4 is limited in operation due to insufficient air intake.

[0049] Refer to Figure 2, the number of the air deflector 1 is two, including the independent left air deflector 10 and right air deflector 11. The left air deflector 10 and the right air deflector 11 are symmetrical to each other. Since the left air deflector 10 and the right air deflector 11 are symmetrical, the following description will take the left air deflector 10 as an example, and the structure and connection of the right air deflector 11 can refer to the left air deflector 10. It should be noted that, taking the perspective of a person standing on one side of the vehicle head looking towards the vehicle tail as the standard, the left and right sides at this time refer to the left hand side and the right hand side of the person respectively.

[0050] Reference Figures 3 to 5 , the left air deflector 10 includes a longitudinal baffle 101 and a transverse mounting plate 102. The longitudinal baffle 101 and the transverse mounting plate 102 are perpendicular to each other; the transverse mounting plate 102 is connected to the engine room frame 5, which plays a role in fixing the left air deflector 10. The longitudinal baffle 101 is used to block the hot air in front of the condenser 4 from flowing to the left and right sides of the condenser 4, avoiding the hot air from flowing back to the rear of the condenser 4. The front of the condenser 4 refers to the side close to the vehicle head bumper. A plurality of threaded holes are provided on the transverse mounting plate 102, and corresponding screw holes are also provided on the engine room frame 5. The transverse mounting plate 102 and the engine room frame 5 are connected together by bolts passing through the threaded holes and the screw holes.

[0051] Optionally, a clamping cavity 1021, a connection hole 1022 and a plug-in part 1023 are provided on the transverse mounting plate 102. Inside the engine room frame 5, there are a water tank bracket and a bumper mounting bracket. The water tank bracket is provided with a plug-in hole and mounting holes corresponding to the connection holes 1022 on the transverse mounting plate 102. The clamping cavity 1021 is clamped on the bumper mounting bracket, and the plug-in part 1023 is inserted into the plug-in hole on the water tank bracket. The connection hole 1022 and the mounting hole on the water tank bracket are connected by a connecting piece, so as to connect the transverse mounting plate 102 with the water tank bracket and the bumper mounting bracket into one body; among them, the bumper mounting bracket and the water tank bracket are respectively connected to the engine room frame 5. In this embodiment, the clamping cavity 1021 on the transverse mounting plate 102 is clamped on the bumper mounting bracket, and the role of the clamping cavity 1021 is positioning. The transverse mounting plate 102 and the bumper mounting bracket can be directly connected or only connected by clamping. The connection hole 1022 on the transverse mounting plate 102 is a threaded hole, and the matching connecting piece is a bolt or a screw. The bolt or the screw passes through the mounting hole and the connection hole 1022 to connect and fix the transverse mounting plate 102 and the water tank bracket.

[0052] Optionally, the left air deflector 10 can be directly integrally formed, or the longitudinal baffle 101 and the transverse mounting plate 102 can be made independently of each other, and then the longitudinal baffle 101 and the transverse mounting plate 102 are connected. When the longitudinal baffle 101 and the transverse mounting plate 102 are independently arranged, the longitudinal baffle 101 is connected to the transverse mounting plate 102. As an example, the longitudinal baffle 101 is adhesively connected to the transverse mounting plate 102. The longitudinal baffle 101 can be adhesively connected to the side of the transverse mounting plate 102 or to the front surface of the transverse mounting plate 102; there are also other connection methods between the longitudinal baffle 101 and the transverse mounting plate 102, such as screw connection, bolt connection, plug connection, etc., which will not be elaborated here. Whether the left air deflector 10 is integrally formed or the longitudinal baffle 101 and the transverse mounting plate 102 are independently made and then connected, its structure needs to be adapted to the specific layout of the automotive engine compartment in addition to meeting the requirements of this embodiment, and can be stably connected at the same time.

[0053] The structure of the right air deflector 11 refers to Figures 6 to 8 , since the right air deflector 11 is symmetrical to the left air deflector 10, it will not be elaborated here.

[0054] Of course, the air deflector 1 can be arranged in front of or behind the condenser 4. The difference is that the heat dissipation effect is different. For example, the air deflector 1 is connected to the left and right sides of the condenser 4 and close to the front side of the condenser 4. The hot air on the front side of the condenser 4 is directly blocked outside the condenser 4 by the air deflector 1, and the heat dissipation effect is the best at this time.

[0055] Although the air deflector 1 can prevent the hot air from flowing back and improve the heat dissipation efficiency of the condenser 4, in extreme working conditions, the problem of insufficient air intake in the engine compartment still affects the normal operation of the condenser 4. For this reason, a ventilation channel 20 is opened on the engine compartment mudguard 2, and the ventilation channel 20 communicates with the inside of the engine compartment frame 5.

[0056] The engine compartment mudguard 2 is used to block the outside sediment from entering the inside of the engine compartment frame 5. Therefore, the engine compartment mudguard 2 is arranged at the lower part of the engine compartment to protect each component inside the engine compartment frame 5. The engine compartment mudguard 2 is connected to the engine compartment frame 5. Specifically, threaded holes are opened on the engine compartment mudguard 2, and screw holes are provided on the engine compartment frame 5. The engine compartment mudguard 2 and the engine compartment frame 5 are connected together by bolts passing through the threaded holes and the screw holes.

[0057] Refer to Figure 9, the ventilation channel 20 is arranged on the side of the engine compartment fender 2 close to the vehicle head. Since the condenser 4 is generally arranged on the side close to the vehicle head, the ventilation channel 20 is located in front of and below the condenser 4. The cold air introduced from the ventilation channel 20 can disperse the hot air in front of the condenser 4, greatly improving the heat dissipation efficiency of the condenser 4. Since the sediment is mainly thrown onto the engine compartment fender 2 by the rotation of the wheels, the ventilation channel 20 is arranged in front of the vehicle head close to it, and the ventilation channel 20 does not affect the normal blocking function of the engine compartment fender 2.

[0058] Of course, in order to further prevent sediment from entering the interior of the engine compartment frame 5 through the ventilation channel 20, a filter screen is provided at the ventilation channel 20. The filter screen is used to filter out sediment and other debris. The filter screen can be arranged on the outside of the ventilation channel 20 or inside the ventilation channel 20. Arranging the filter screen on the outside of the ventilation channel 20 is beneficial for replacing the filter screen at any time. The filter screen is generally adhered to the ventilation channel 20, and the filter screen can be made of PVC material.

[0059] The setting form of the ventilation channel 20 is a through hole, and the shape of the through hole is a round hole, a square hole, an oval hole. Of course, the shape of the through hole can also be other shapes such as a rhombus or a petal shape.

[0060] The ventilation channel 20 on the engine compartment fender 2 solves the problem of insufficient air intake in the engine compartment under extreme working conditions, enabling the condenser 4 to always operate normally and dispersing the hot air in front of the condenser 4, improving the heat dissipation efficiency.

[0061] Generally, a cooling fan 3 is arranged in the vehicle engine compartment to accelerate the heat dissipation in the engine compartment through the cooling fan 3. The condenser 4 is generally arranged on the air outlet side of the cooling fan 3, and the air flow discharged by the cooling fan 3 takes the heat on the condenser 4 out of the engine compartment frame 5.

[0062] In summary, the vehicle engine compartment provided by the embodiment of the present invention arranges the engine compartment fender 2 on the engine compartment frame 5. The engine compartment fender 2 is provided with a ventilation channel 20, and the ventilation channel 20 is located in front of and below the condenser 4. The outside cold air is introduced into the engine compartment through the ventilation channel 20, thereby dispersing the hot air in front of the condenser 4, improving the heat dissipation efficiency of the condenser 4, and at the same time solving the problem that the function of the condenser 4 is limited due to insufficient air intake under extreme working conditions; in addition, air guiding plates 1 are arranged on both sides of the condenser 4 to block the hot air in front of the condenser 4 from flowing back, effectively reducing the temperature in front of the condenser 4.

[0063] The embodiment of the present invention also provides a new energy vehicle, including the above vehicle engine compartment. The bumper of the vehicle covers the outside of the air guiding plate 1 for protecting the air guiding plate 1.

[0064] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described above.
