[0002] The automobile radiator is an important component of the vehicle cooling system. Its main function is to help the engine maintain an optimal temperature range. At present, the cooling of the radiator is achieved by opening a hole in the bumper grille to connect the air outside the vehicle, and setting two air guides on both sides of the radiator. After the bumper is installed, the air guide will bend and rely on the rebound force to act as a seal. In this way, the air guide will smoothly guide the air into the radiator, cool the fluid in the radiator, reduce air resistance, and prevent the air flow between the grille and the radiator from forming turbulence. However, a gap is easily generated between the air guide and the bumper, which reduces the air tightness, deteriorates the air flow guidance, and worsens the heat dissipation effect.
[0003] Therefore, it is necessary to provide a new air deflector, heat dissipation structure and vehicle to solve the above technical problems. Utility Model Content

[0006] A connecting plate, the connecting plate being used to connect to the radiator;
[0007] The sealing plate includes a first connecting section and a second connecting section connected to each other, wherein one end of the first connecting section away from the second connecting section is connected to the connecting plate, and the second connecting section includes a contact surface for abutting against a bumper formed with a grid.
[0008] In one embodiment, there are multiple sealing plates, and the multiple sealing plates are staggered along the length direction of the connecting plate, and the directions of two adjacent second connecting sections are opposite.
[0009] In one embodiment, the length of the contact surface along a length direction perpendicular to the length of the connecting plate is 4.8 mm to 5.2 mm.
[0010] In one embodiment, the first connecting section is bent.

[0014] In one embodiment, the heat sink is provided with a first magnet, and the connecting plate is provided with a second magnet, and the first magnet and the second magnet attract each other.
[0015] In one embodiment, the radiator is formed with a first mounting hole, and the connecting plate is formed with a second mounting hole, the number of the first mounting holes is two, and the heat dissipation structure also includes two fasteners, one fastener is installed in one second mounting hole through one first mounting hole, and the other fastener is installed in another second mounting hole through another first mounting hole.
[0016] The utility model further provides a vehicle, comprising a bumper and the above-mentioned heat dissipation structure, wherein the bumper comprises a grid, and the contact surface abuts against the bumper.
[0017] In the above scheme, the air deflector includes a connecting plate and a sealing plate, the connecting plate is used to be connected to the radiator, the sealing plate includes a first connecting section and a second connecting section that are connected to each other, the end of the first connecting section away from the second connecting section is connected to the connecting plate, and the second connecting section includes a contact surface, which is used to abut against the bumper formed with a grid.

At this time, the sealing plate will abut against the bumper, and the elastic sealing plate will bend, that is, the first connecting plate will bend, and the contact surface of the second connecting section will be in surface contact with the bumper, thereby greatly increasing the contact surface between the bumper and the second connecting section. In the prior art, when air flows into the vehicle through the grille holes on the bumper to cool the radiator, the pressure on the air deflector increases when the vehicle is traveling at high speed. Since the air deflector is in point contact with the bumper, when the pressure is greater than the pressure on the outside of the air deflector, the air deflector will easily deform to both sides and lose contact with the bumper, and the sealing performance will be greatly reduced. In the present invention, a contact surface is provided on the second connecting section, so that the second connecting section and the bumper are changed from point contact to surface contact, thereby greatly increasing the friction between the second connecting section and the bumper.

[0028] The car radiator is an important part of the vehicle cooling system. Its main function is to help the engine maintain an optimal temperature range. At present, the cooling of the radiator is achieved by opening a hole in the bumper grille to connect the air outside the car, and setting two air guides on both sides of the radiator. After the bumper is installed, the air guide will bend and rely on the rebound force to play a sealing role. In this way, the air guide will smoothly guide the air into the radiator, cool the fluid in the radiator, reduce air resistance, and prevent the air flow between the grille and the radiator from forming turbulence. However, during user use, noise often occurs and the heat dissipation effect of the radiator is poor. , which has a very important impact on the user's use; the applicant has found through research that since the current air deflector and bumper are in point contact, the friction between the air deflector and the bumper is small. Therefore, when the vehicle is traveling at high speed, the pressure between the air deflector increases and is greater than the pressure on the outside of the air deflector. At the same time, the friction between the air deflector and the bumper is small, so the pressure will be greater than the friction, causing the air deflector to separate from the bumper. After the air deflector and the bumper are separated, it is easy to vibrate when driving, which will generate noise. In addition, due to the gap, the air tightness is reduced, the air flow guidance is worse, and the heat dissipation effect is worse. In order to ensure the effect of the air deflector and reduce noise, please refer to Figures 1 to 3The utility model proposes an air deflector 1, including a connecting plate 11 and a sealing plate 12, the connecting plate 11 is used to connect to the radiator 201, the sealing plate 12 includes a first connecting section 121 and a second connecting section 122 connected to each other, the first connecting section 121 is connected to the connecting plate 11 at one end away from the second connecting section 122, the second connecting section 122 includes a contact surface 122a, and the contact surface 122a is used to abut against the bumper 202 formed with a grid 202a. Specifically, the connecting plate 11 and the sealing plate 12 are connected, and then the air deflector 1 is installed on the radiator 201, and then the bumper 202 is installed. At this time, the sealing plate 12 will abut against the bumper 202, and the elastic sealing plate 12 will bend, that is, the first connecting plate 11 will bend, and the contact surface 122a of the second connecting section 122 will contact the bumper 202 surface, thereby greatly increasing the contact surface 122a between the bumper 202 and the second connecting section 122; in the prior art, when the airflow enters the vehicle through the grid 202a hole on the bumper 202 to cool the radiator 201, when the vehicle is traveling at high speed, The pressure on the air deflector 1 increases. Since the air deflector 1 is in point contact with the bumper 202, when the pressure is greater than the pressure on the outside of the air deflector 1, the air deflector 1 will easily deform to the sides, breaking away from the contact with the bumper 202, and the sealing performance will be greatly reduced. However, in the present invention, a contact surface 122a is provided on the second connecting section 122, so that the second connecting section 122 and the bumper 202 are in surface contact instead of point contact. This greatly increases the friction between the second connecting section 122 and the bumper 202, so that when the air deflector 1 is under pressure, it is not easy to separate from the bumper 202, thereby greatly improving the airtightness of the air deflector 1. The technical solution of the present invention improves the friction between the second connecting section 122 and the bumper 202 by changing the point contact between the second connecting section 122 and the bumper 202 to surface contact, so that when the air deflector 1 is under pressure, it is not easy to separate from the bumper 202, thereby improving the airtightness of the air deflector 1.
[0029] See also Figures 1 to 3 In one embodiment, multiple sealing plates 12 are provided, staggered along the length of the connecting plate 11, with adjacent second connecting segments 122 facing in opposite directions. Multiple sealing plates 12 are provided, staggered along the length of the connecting plate 11, so that adjacent first connecting segments 121 bend toward opposite sides. This simultaneously restricts the movement of the air deflector 1 in both directions, making it difficult for the air deflector 1 to move after installation, thereby preventing it from separating from the bumper 202.
[0030] In one embodiment, the length of the contact surface 122a along the length direction perpendicular to the connecting plate 11 is 4.8 mm to 5.2 mm. Specifically, by setting the length of the contact surface 122a along the length direction perpendicular to the connecting plate 11 to 4.8 mm to 5.2 mm, the maximum pressure on the air deflector 1 is ensured to be less than the friction between the contact surface 122a and the bumper 202. This ensures that the air deflector 1 does not separate from the bumper 202. At the same time, the contact surface 122a is prevented from being too large, which would increase the space occupied.
[0031] See also Figures 1 to 3 In one embodiment, the first connecting section 121 is bent. Specifically, the first connecting section 121 is bent so that the first connecting section 121 of the air deflector 1 is curved before installation. During installation, the first connecting section 121 of the air deflector 1 can be bent more smoothly. When the bumper 202 is manually installed, the first connecting section 121 is not squeezed and bent, thereby preventing the first connecting section 121 from being damaged or broken.
[0032] In one embodiment, the wind deflector 1 is a resin wind deflector 1. The resin wind deflector 1 is made of resin material, which is lighter than metal, making installation and maintenance easier. In addition, the resin has good chemical stability and is not easily corroded. The resin wind deflector 1 can be made into various shapes and sizes through molding or other manufacturing processes. The resin wind deflector 1 is lower in cost and requires less maintenance due to its durability and corrosion resistance.
[0033] See also Figures 1 to 3The present invention also provides a heat dissipation structure 200, including a radiator 201 and two of the above-mentioned air deflectors 1, the two air deflectors 1 being connected to both sides of the radiator 201, and the two air deflectors 1 being symmetrically arranged. Specifically, the two heat dissipation plates are connected to both sides of the radiator 201, so that the two sealing plates 12 are respectively in contact with the bumper 202, and the grid 202a is located between the two sealing plates 12. The elastic sealing plate 12 will bend, that is, the first connecting plate 11 will bend, and the contact surface 122a of the second connecting section 122 will be in surface contact with the bumper 202, thereby greatly increasing the contact surface 122a between the bumper 202 and the second connecting section 122, and changing the point contact between the second connecting section 122 and the bumper 202 to surface contact, thereby improving the heat dissipation performance. The friction between the second connecting section 122 and the bumper 202 is reduced. In this way, when the pressure inside the heat dissipation structure 200 is greater than the external pressure, the friction between the air guide plates 1 on both sides and the bumper 202 is greater than the pressure inside the heat dissipation structure 200. In this way, the air guide plates 1 on both sides will not be separated from the bumper 202, thereby improving the air tightness of the air guide plates 1; since the heat dissipation structure 200 includes all implementation methods of all the above-mentioned embodiments of the air guide plates 1, it at least has all the beneficial effects brought about by all the above-mentioned implementation methods, which will not be repeated here.
[0034] In fact, multiple sealing plates 12 in an air guide plate 1 can be spaced apart along the length direction of the connecting plate 11, so that the two air guide plates 1 are symmetrically arranged on the radiator 201. This can also limit the movement of the air guide plate 1 to both sides, improve it, and ensure that the air guide plate 1 does not separate from the bumper 202.
[0035] In one embodiment, the heat sink 201 is provided with a snap-fit groove, and the connecting plate 11 is provided with a snap-fit, which snap-fits into the snap-fit groove. Specifically, the snap-fit on the connecting plate 11 is snap-fitted into the snap-fit groove of the heat sink 201, thereby connecting the connecting plate 11 to the heat sink 201. When disassembly is required, the connecting plate 11 and the heat sink 201 can be disassembled by simply removing the snap-fit. This structure is simple and convenient to operate and is simple to manufacture.
[0036] In one embodiment, a first magnet is provided on the heat sink 201, and a second magnet is provided on the connecting plate 11. The first magnet and the second magnet attract each other. This structure can improve the connection strength between the heat sink 201 and the connecting plate 11 and also enable quick removal and installation of the heat sink 201 and the connecting plate 11.
[0037] In one embodiment, a first mounting hole is formed on the radiator 201, and a second mounting hole is formed on the connecting plate 11. The number of the first mounting holes is two. The heat dissipation structure 200 also includes two fasteners, one fastener is installed in a second mounting hole through a first mounting hole, and the other fastener is installed in another second mounting hole through another first mounting hole. When it is necessary to connect the air deflector 1 and the radiator 201, the locking member is installed in the second mounting hole of the air deflector 1 through the first mounting hole. In this way, the air deflector 1 and the radiator 201 are connected. This connection method greatly improves the connection strength and the air deflector 1 will not be separated from the radiator 201. When it is necessary to disassemble the air deflector 1 and the radiator 201, the locking member is removed from the second mounting hole. In this way, the air deflector 1 and the radiator 201 are disassembled. This connection method greatly improves the disassembly efficiency.
[0038] The present invention further provides a vehicle including a bumper and the above-described heat dissipation structure 200, wherein the bumper 202 includes a grid 202a, and the contact surface 122a abuts against the bumper 202. Since the vehicle includes all embodiments and implementations of the above-described heat dissipation structure 200, it has at least all the beneficial effects brought about by all the above-described implementations, which will not be detailed here.
[0039] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
