Description

Technical Field

[0001] This utility model relates to the field of automotive engine cooling, specifically to an automotive cooling module airflow structure and an automotive. Background Technology

[0002] To prevent hot air from flowing back into the engine compartment during idling or low-speed operation and to improve the cooling module's heat dissipation, a common solution is to add air guide plates around the cooling module. These plates block hot air from flowing back into the engine compartment and passing through the cooling module, thus preventing the hot air from affecting its heat dissipation.

[0003] However, when a car is traveling at high speed, the engine output power is extremely high, resulting in very high temperatures inside the engine compartment. The air deflectors surrounding the cooling module prevent ambient air from entering, and this high-temperature environment not only hinders heat dissipation for the engine compartment components but also accelerates component aging and shortens their lifespan. Utility Model Content

[0004] The purpose of this invention is to provide an air guide structure for an automotive cooling module and an automotive vehicle, which can effectively prevent hot air from flowing back into the engine compartment in idle or low-speed modes, and can introduce some outside air in medium-speed and high-speed modes to reduce the temperature inside the engine compartment.

[0005] The embodiments of this utility model are implemented as follows:

[0006] In a first aspect, an embodiment of this application provides an air guide structure for an automotive cooling module, installed in the heat dissipation area on the side of the cooling module in the engine compartment of an automotive vehicle and at the position of the air intake grille at the front of the vehicle; the air guide structure includes an air guide plate, the air guide plate includes a plate body and an air intake port, the air intake port is connected to the plate body, the air intake port is located on one side of the air intake grille, the plate body is also disposed opposite to the heat dissipation area, the plate body has an air vent, the inner side of the air vent is provided with a louver structure, the louver structure includes blades that can swing relative to the corresponding air vent to open;

[0007] When the vehicle is in idle or low speed mode, the pressure of the air entering through the air intake grille and the air guide plate is less than or equal to the weight of the blades, and the blades are attached to the corresponding air guide openings; when the vehicle is in medium or high speed mode, the pressure of the air entering through the air intake grille and the air guide openings is greater than the weight of the blades, and the air opens the blades after passing through the air intake port to enter the heat dissipation area.

[0008] In some embodiments, each of the protective plate bodies has an air intake channel communicating with the corresponding air intake port, and when the blades are in the open state, the air intake channel is communicating with the heat dissipation area.

[0009] In some embodiments, the surface area of ​​each blade is smaller than the area of ​​the corresponding air vent, and a sealing ring of a set width is provided on the side of the blade; when the vehicle is in idle or low speed mode, the blade is located inside the corresponding air vent, and the outer side of the corresponding sealing ring is sealed to the inner wall of the air vent.

[0010] In some embodiments, a pivot shaft extends through the top of each blade, and the two ends of the pivot shaft are rotatably connected to the two sides of the top of the corresponding air guide.

[0011] In some embodiments, a limiting block is also provided on the side wall at one end of the rotating shaft. When the blade swings at a set angle away from the air guide during the opening process, the limiting block contacts the baffle on the main body of the protective plate.

[0012] In some implementations, the set angle is 90°.

[0013] In some embodiments, each of the air inlets is provided with a dustproof grille, the orientation of which is consistent with the opening direction of the corresponding blade.

[0014] In some embodiments, each of the protective plate bodies is provided with multiple air vents and the louver structure on the same side relative to the cooling module; when the vehicle is in medium or high speed mode, the blades on the same protective plate body open in the same direction.

[0015] In some embodiments, the air guide and the blade have rectangular cross-sections along their plate direction, the length and width dimensions of the air guide are 38.5 mm and 25.5 mm, respectively, the length and width dimensions of the blade are 38 mm and 25 mm, respectively, and the width dimension of each of the damping pads is 0.7 mm.

[0016] Secondly, an embodiment of the present application provides an automobile, including an engine compartment and an air intake grille. A cooling module is provided in the engine compartment, and the air intake grille is located at the front of the automobile. The air intake grille communicates with the engine compartment and is used to supply air to the cooling module when the automobile is in medium-speed or high-speed mode. The automobile also includes an air guide structure as described above, which is installed at the locations of the cooling module and the air intake grille.

[0017] The beneficial effects of this utility model embodiment are as follows: In conjunction with the above embodiments, when the vehicle is idling or driving at low speed, the engine generates less heat, and the cooling module cools the engine compartment by drawing in external air. Because the louvered structure's blades are located on the inner side of the protective plate body, these blades are in close contact with the corresponding air vents, preventing heat from being drawn into the cooling module and effectively avoiding heat backflow.

[0018] When the car is traveling at medium or high speed, the outside air is divided into two paths. One path of air enters the cooling module through the middle area of ​​the air intake grille, while the other path of air enters the air intake port and the main body of the guard plate through both sides of the air intake grille. The pressure of the outside air on the blades is greater than the weight of the blades, thus opening the corresponding air vents. The second path of air then enters the heat dissipation area, thereby cooling the functional components in the heat dissipation area. This makes full use of the air entering through the air intake grille and effectively meets the needs of rapid heat dissipation of various functional components inside the engine compartment when the car is traveling at medium or high speed.

[0031] The engine compartment of a car typically houses a cooling module (such as an air cooler). On either side of this module are corresponding heat dissipation areas, which contain various functional components. The car's front grille connects to the engine compartment and, during medium or high-speed driving, draws air into the cooling module and heat dissipation areas. This means the first stream of air cools the engine compartment through the cooling module, and the second stream cools the functional components within the heat dissipation areas. When the car is idling or driving at low speeds, the engine generates less heat, and the cooling module draws in outside air to cool the engine compartment. To prevent heat from flowing back into the engine compartment, air deflectors are usually installed on either side of the cooling module. These deflectors separate the cooling module from the heat-generating areas of the engine compartment, preventing heat from being drawn into the cooling module and reducing its cooling efficiency. However, when the car is traveling at medium or high speeds, air enters the cooling module through the middle area of ​​the air intake grille, while air entering through the sides of the air intake grille is blocked by the air deflectors and cannot enter the cooling module, resulting in a waste of this air and failing to meet the demand for rapid engine cooling when the car is traveling at medium or high speeds.

[0032] First Embodiment

[0033] refer to Figures 1 to 4 This application discloses an airflow guide structure for an automotive cooling module, installed on the side of the cooling module in the engine compartment of an automobile, at the location of the heat dissipation area and the front air intake grille of the automobile. The heat dissipation area refers to the area corresponding to both sides of the cooling module, and functional components are arranged inside this heat dissipation area. The airflow guide structure includes an airflow guide plate, which includes a plate body 1 and an air intake port 2. The air intake port 2 is connected to the corresponding plate body 1 and is located on one side of the air intake grille. The plate body 1 is located on one side of the cooling module. The plate body 1 is also positioned opposite to the heat dissipation area and has an air vent 3. A louver structure 4 is provided on the inner side of the air vent 3, and the louver structure 4 includes blades 41 that can swing relative to the corresponding air vent 3 to open. When the car is idling or in low-speed mode, the pressure of the air entering through the air intake grille and air deflector is less than or equal to the weight of the blade 41, and the blade 41 is attached to the corresponding air deflector 3; when the car is in medium-speed or high-speed mode, the pressure of the air entering through the air intake grille and air deflector is greater than the weight of the blade 41, and the air opens the blade 41 through the air intake port 2 to enter the heat dissipation area.

[0034] In the above embodiments, when the car is idling or driving at low speed, the engine generates less heat, and the cooling module cools the engine compartment by drawing in external air. Since the blades 41 of the louver structure 4 are located on the inner side of the guard plate body 1, the pressure of the air entering through the air intake grille and air guide plate is less than or equal to the weight of the blades 41. At this time, the blades 41 are in close contact with the corresponding air guide 3, and the heat inside the engine compartment will not be drawn into the cooling module, effectively preventing heat backflow.

[0035] In some embodiments, two air guide plates are provided, which are respectively arranged on the heat dissipation areas on both sides of the cooling module, so as to achieve sufficient heat dissipation of functional components in the heat dissipation area.

[0036] When the car is traveling at medium or high speed, the outside air is divided into two paths. One path of air enters the cooling module through the middle area of ​​the air intake grille, and the cooling module dissipates heat from the engine compartment. The other path of air enters the air intake port 2 and the guard plate body 1 through the two sides of the air intake grille. The pressure of the air entering through the air intake grille and the air guide is greater than the weight of the blades 41, thereby opening the corresponding air guide 3. The second path of air enters the heat dissipation area, thereby dissipating heat from the functional components in the heat dissipation area. This makes full use of the air entering through the air intake grille and better meets the need for rapid cooling of the engine when the car is traveling at medium or high speed.

[0037] In the automotive cooling module air guide structure of this application embodiment, each guard plate body 1 has an air intake channel connected to the corresponding air intake port 2. When the blades are in the open state, the air intake channel is connected to the heat dissipation area.

[0038] In conjunction with the above embodiments, each skid plate body 1 has an "L"-shaped cross-section. During installation, the skid plate body 1 is sealed and fastened within the installation area of ​​the engine compartment, thus forming an air intake channel with that area. Each air intake port is flared, with the larger opening located on one side of the air intake grille. When the vehicle is traveling at medium or high speeds, a second stream of air enters the cooling area through the air intake port, air intake channel, and air vent, thereby improving the cooling efficiency of the cooling module.

[0039] In the air guide structure of the automotive cooling module of this application embodiment, the surface area of ​​each blade 41 is smaller than the area of ​​the corresponding air guide port, and a sealing ring of a set width is provided on the side of the blade 41; when the car is in idle or low speed mode, the blade 41 is located inside the corresponding air guide port 3, and the outer side of the corresponding sealing ring is sealed to the inner side wall of the air guide port 3.

[0040] In conjunction with the above embodiments, the area of ​​each blade 41 is smaller than the area of ​​the corresponding air vent 3, allowing the blade 41 to be completely placed within the air vent 3. Simultaneously, sealing rings are provided on the sides of the blade 41 (bottom and left and right side sides). The width of the sealing rings is slightly larger than the gap between each side of the blade 41 and the corresponding inner wall of the air vent 3. Due to the elasticity of the sealing rings, when the blade 41 is in the closed state (i.e., the car is idling or driving at low speed), the blade 41 can completely seal the corresponding air vent 3, preventing heat from the engine compartment from flowing back to the cooling module and avoiding a reduction in the cooling module's heat dissipation efficiency. Furthermore, the sealing rings can buffer the impact force when the blade 41 closes, extending the service life of the blade 41. The sealing rings are made of elastic materials such as rubber, which can absorb the vibration noise generated when the blade 41 is closed, improving NVH (Noise, Vibration, Harshness) performance and enhancing the user experience.

[0041] In the automotive cooling module air guide structure of this application embodiment, each blade 41 has a rotating shaft passing through its top, and the two ends of the rotating shaft are rotatably connected to the two sides of the top of the corresponding air guide 3.

[0042] In conjunction with the above embodiments, the blade 41 and the corresponding air vent 3 are rotatably connected by a rotating shaft. The rotating shaft is located at the top of the blade 41 and the air vent 3. When the car slows down from medium or high speed to low speed or idling speed, the blade 41 can swing downward by its own weight, thereby automatically closing the air vent 3.

[0043] In the air guide structure of the automotive cooling module of this application embodiment, a limit block is also provided on the side wall of one end of the rotating shaft. The entire rotating shaft is L-shaped. When the blade swings away from the air inlet at a set angle (such as 90°), the limit block contacts the baffle on the air guide plate, thereby restricting the blade 41 from continuing to rotate. The limit block not only strengthens the structural strength of the air guide plate, but also limits the maximum swing angle of the blade 41, preventing the blade 41 from swinging too much and failing to automatically reset.

[0044] The air guide structure of the automotive cooling module in this embodiment of the application has a set angle of 90°.

[0045] In the air guide structure of the automotive cooling module of this application embodiment, each air guide 3 is provided with a dustproof grille 42, and the orientation of the dustproof grille 42 is consistent with the opening direction of the corresponding blade 41.

[0046] In conjunction with the above embodiments, the dust grille 42 can prevent sand, blades and other debris from the external ambient air from entering the engine compartment through the air vent 3, thus keeping the interior of the engine compartment clean.

[0047] In the automotive cooling module air guide structure of this application embodiment, each guard plate body 1 is provided with multiple air guide ports 3 and louver structures 4 on the same side relative to the cooling module; when the car is in medium speed or high speed mode, the blades 41 located on the same guard plate body 1 open in the same direction.

[0048] In conjunction with the above embodiments, each windshield body 1 can have multiple air vents 3 and louver structures 4. The number of air vents 3 and louver structures 4 matches the engine displacement of the vehicle. For large-displacement vehicles (such as vehicles with a displacement of 2.0t), two or more air vents 3 and louver structures 4 can be set on each windshield body 1 to meet the greater heat dissipation requirements of the engine. For small-displacement vehicles (such as vehicles with a displacement of 1.0t), one air vent 3 and louver structure 4 can be set on each windshield body to meet the smaller heat dissipation requirements of the engine.

[0049] In this embodiment of the automotive cooling module air guide structure, the air guide 3 and the blades 41 have rectangular cross-sections along their plate direction. The length and width dimensions of the air guide 3 are 38.5mm and 25.5mm, respectively. The length and width dimensions of the blades 3 are 38mm and 25mm, respectively. The width dimension of each damping pad is 0.7mm.

[0050] Second Embodiment

[0051] This application also provides a car. Since the implementation principle of the car in this embodiment is the same as or similar to the air guide structure of the car cooling module in the above embodiments, the specific implementation of the car in this application can refer to the air guide structure of the car cooling module in any of the above embodiments, and the repeated parts will not be described again.

[0052] This application provides an embodiment of an automobile, including an engine compartment and an air intake grille. A cooling module is provided in the engine compartment, and the air intake grille is located at the front of the automobile. The air intake grille is connected to the engine compartment and is used to supply air to the cooling module when the automobile is in medium or high speed mode. The automobile also includes the air guide structure in any of the above embodiments, which is installed in the heat dissipation area corresponding to the cooling module and at the location of the air intake grille.
