Abstract
Description
Technical Field
[0001] This utility model applies to the technical field of airflow guiding devices, and particularly relates to an airflow guiding device for a front heat sink. Background Technology
[0002] With the rapid development of new energy vehicles, the thermal management technology of pure electric buses faces multiple challenges under complex operating conditions, especially in mountainous suburban areas with bumpy roads and in coastal environments with high humidity and high salinity. Traditional heat dissipation and corrosion protection designs have significant limitations. Some models can only place the radiator assembly at the front of the vehicle, with the radiator assembly drawing air in from the front and expelling it from the rear, with the airflow direction directly towards the underside of the vehicle. In frequent braking scenarios in suburban areas, the performance degradation of the front wheel brake discs due to heat fade is a prominent issue.
[0003] Existing technologies largely rely on independent cooling devices (such as independent fans or liquid cooling systems), but these solutions suffer from high energy consumption and complex structures. In coastal and rainy areas, mud and water splashed by the front wheels easily adhere to the chassis frame and wheel arches, accumulating over time and accelerating corrosion of metal components. Traditional passive drainage designs (such as drain holes) cannot actively remove water mist, and residual salt further exacerbates corrosion. Mudguards can only block large particles of mud and water, failing to address the issue of water mist adhesion from the wheels. Anti-corrosion coatings are prone to aging and failure in long-term high-salt environments. After parking, the lack of active drying mechanisms for residual moisture in the chassis accelerates corrosion of metal components, and existing motor and electronic control cooling systems shut down immediately after vehicle stopping, resulting in unused residual heat. In high-humidity environments, residual moisture in the chassis cannot evaporate promptly, increasing the risk of corrosion. If a simple, partitioned radiator drainage device with simultaneous drainage could be designed for the front radiator, these problems could be solved. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a flow guiding device for a front radiator that has a simple structure, can guide the flow of the radiator in sections, and can realize synchronous drainage.
[0005] The technical solution adopted by this utility model is as follows: This utility model includes a main body of a flow guiding device, which includes an upper flow guiding cavity and a lower flow guiding cavity. The upper flow guiding cavity is disposed at the upper end of the lower flow guiding cavity. An installation transverse groove is provided between the air inlet end of the upper flow guiding cavity and the air inlet end of the lower flow guiding cavity. An upper flow guiding plate is provided in the installation transverse groove. The upper flow guiding plate is connected to the adjacent side of the air inlet end of the upper flow guiding cavity and the air inlet end of the lower flow guiding cavity, respectively. Upper air outlets are provided on both sides of the upper flow guiding cavity. A plurality of lower air outlets are provided on both sides of the air outlet end of the lower flow guiding cavity. The radiator cooperates with the plurality of upper air outlets and the plurality of lower air outlets through the air inlet ends of the upper and lower flow guiding cavities, respectively.
[0006] Furthermore, the bottom of the lower flow guide cavity is provided with a plurality of bottom air outlet slots, and the lower end face of the lower flow guide cavity is provided with a bottom flow guide cover, which cooperates with the plurality of bottom air outlet slots.

[0008] Furthermore, the lower guide plate is configured with a V-shaped deflection structure, and the main body parts on both sides of the lower guide plate are respectively matched with the corresponding lower air outlets.

[0012] Furthermore, a supporting rib is provided between the lower guide cavity and the upper guide cavity.
[0013] Furthermore, both ends of the upper guide plate are provided with connecting side plates, and the upper guide plate is connected to the air guide mounting holes on both sides of the air inlet end of the lower guide cavity through the connecting side plates.
[0014] The beneficial effects of this utility model are as follows: the airflow from the radiator is directed to the front brake disc through the airflow guiding structure, and the forced convection is used to reduce the temperature of the brake disc, reduce the risk of heat fade, avoid additional energy consumption, and improve the braking heat dissipation efficiency; in rainy weather, the airflow actively disperses the water mist splashed by the front wheels, reducing the deposition of mud and water on the chassis frame; after parking, the operation of the cooling system is extended, and the waste heat is used to dry the components with warm air, inhibiting salt spray corrosion and actively preventing dirt and corrosion; the waste heat from the motor and electronic control system is converted into usable resources for brake cooling and chassis drying, improving energy utilization efficiency and enabling the reuse of energy.

Detailed Implementation
[0016] like Figures 1 to 5As shown, in this embodiment, the present invention includes a main body 1 of a flow guiding device. The main body 1 of the flow guiding device includes an upper flow guiding cavity 2 and a lower flow guiding cavity 3. The upper flow guiding cavity 2 is disposed at the upper end of the lower flow guiding cavity 3. A mounting transverse groove 4 is provided between the air inlet end of the upper flow guiding cavity 2 and the air inlet end of the lower flow guiding cavity 3. An upper flow guiding plate 5 is provided in the mounting transverse groove 4. The upper flow guiding plate 5 is connected to the adjacent side of the air inlet end of the upper flow guiding cavity 2 and the air inlet end of the lower flow guiding cavity 3, respectively. Upper air outlets 6 are provided on both sides of the upper flow guiding cavity 2. A plurality of lower air outlets 7 are provided on both sides of the air outlet end of the lower flow guiding cavity 3. The radiator 8 cooperates with the plurality of upper air outlets 6 and the plurality of lower air outlets 7 through the air inlet ends of the upper flow guiding cavity 2 and the lower flow guiding cavity 3, respectively. Therefore, the mounting groove 4 is used to secure the upper guide cavity 2 and the lower guide cavity 3 to the vehicle chassis crossbeam. The airflow blown out by the radiator 8 is divided into sections by the upper guide plate 5 and blown into the upper guide cavity 2 and the lower guide cavity 3 to achieve the guiding effect. Then, the airflow is directed to the front frame of the front wheel arch and the brake disc and the rear frame of the front wheel arch through the upper air outlet 6 and the lower air outlet 7. When the vehicle is driving in rainy weather, the upper air outlet 6 mainly reduces the adhesion of mud and water to the front frame of the front wheel arch. When the vehicle is driving in non-rainy weather, its main function is to provide additional cooling for the brake discs. The lower air vent 7 mainly serves to reduce mud and water adhesion to the front wheel arch frame when the vehicle is driving in the rain. It also combines the adjustment of the working strategy of the motor and electronic control cooling system, such as through manual control or control by the vehicle controller combined with rain detection. After driving a certain distance in rainy or high humidity environments, the vehicle stops and the working time of the electronic water pump and cooling fan of the motor and electronic control cooling system is appropriately extended. This allows the residual heat of the motor and electronic control system to dry or blow dry the frame, front brake disc and related components at the front wheel arch, reducing the corrosion of steel components by rainwater and the damage of salt spray to the anti-corrosion coating on the steel surface.
[0017] like Figure 2 and Figure 3 As shown, in this embodiment, the lower airflow cavity 3 has several bottom air outlet slots 9 at its bottom, and a bottom airflow hood 10 is provided on the lower end face of the lower airflow cavity 3. The bottom airflow hood 10 cooperates with the several bottom air outlet slots 9. Therefore, the lower airflow cavity 3, in conjunction with the bottom airflow hood 10, can divert a portion of the airflow within the lower airflow cavity 3 to the front side of the vehicle frame fixing position, thereby achieving the diversion and flushing of accumulated rainwater or silt.
[0018] like Figure 3As shown, in this embodiment, a guide plate mounting port 11 is provided at the bottom of the air outlet of the lower guide cavity 3, and a lower guide plate 12 is provided at the guide plate mounting port 11. The lower guide plate 12 cooperates with two sets of lower air outlets 7. It can be seen that the lower guide plate 12 can compress the space at the front end of the lower guide cavity 3, so that the airflow can flow out more stably from the two sets of lower air outlets 7.
[0019] like Figure 3 and Figure 5 As shown, in this embodiment, the lower guide plate 12 is configured with a V-shaped deflection structure, and the main body portions on both sides of the lower guide plate 12 respectively cooperate with the corresponding lower air outlets 7. Therefore, the guide plates on both sides of the lower guide plate 12 correspond to the two sets of lower air outlets 7, so that the airflow entering the lower guide cavity 3 is stably diverted to the two sets of lower air outlets 7 through the lower guide plate 12.
[0020] like Figure 4 As shown, in this embodiment, upper drainage channels 13 are provided at the bottom of both sides of the upper drainage cavity 2. Therefore, the upper drainage channels 13 can drain the rainwater accumulated in the upper drainage cavity 2.
[0021] like Figure 4 As shown, in this embodiment, lower drainage channels 14 are provided at the bottom of both sides of the lower drainage cavity 3. Therefore, the lower drainage channels 14 can drain the rainwater accumulated in the lower drainage cavity 2.
[0022] like Figure 2 As shown, in this embodiment, a connecting plate 15 is provided at the lower end of the lower flow guide cavity 3. The connecting plate 15 is provided with a plurality of locking holes 16, which are connected to the external fixing frame through the mounting transverse groove 4. Therefore, the chassis crossbeam is connected and fixed to the plurality of locking holes 16 within the mounting transverse groove 4 by fastening components.
[0023] like Figure 2 As shown, in this embodiment, a supporting rib plate 17 is provided between the lower flow guide cavity 3 and the upper flow guide cavity 2. Therefore, the supporting rib plate 17 connects the rear sections of the upper and lower flow guide cavities together by welding, improving the structural strength of the upper and lower flow guide cavities and reducing low-frequency vibration and noise.
[0024] like Figure 3As shown, in this embodiment, both ends of the upper guide plate 5 are provided with connecting side plates 18. The upper guide plate 5 is connected to the air guide mounting holes 19 on both sides of the air inlet end of the lower guide cavity 3 through the connecting side plates 18. Therefore, the upper guide plate 5 is installed at the air inlet end of the upper guide cavity 2 through the connecting side plates 18. This is mainly to ensure that after the main body of the guide device is properly installed, the exhaust side of the cooling fan has a larger area aligned with the air inlet end of the upper guide cavity 2, thus providing a larger airflow into the upper guide cavity 2.
[0025] The working principle of this utility model is as follows: Before starting the equipment, the air guide device is connected and locked to the crossbeam of the car chassis through the mounting groove 4. Then, the air inlet of the air guide device is connected to the air outlet of the radiator 8. When the vehicle is running, the electronic water pump of the motor control cooling system and the cooling fan installed in the radiator work. The electronic water pump delivers the coolant, which has absorbed the heat of the motor control system, to the radiator. The cooling fan forces air to flow through the radiator. The heat in the coolant is exchanged with the air through the heat dissipation fins on the radiator and discharged into the air guide device assembly. The radiator 8 blows the airflow into the upper air guide cavity 2 and the lower air guide cavity 3. The airflow is directed to the front frame of the front wheel arch and the brake disc and the rear frame of the front wheel arch through the upper air outlet 6 and the lower air outlet 7. At the same time, the rainwater flowing in from the air inlet is quickly discharged through the drainage channel structure.
[0026] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
