Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a front bumper cooling fin type ventilation device. Background Technology

[0002] As an important component of the front end of the car body, the traditional functions of the front bumper are to provide buffer protection in low-speed collisions and to serve as a key aesthetic element in the overall vehicle design. With the development of the automotive industry, the power performance and driving speed of vehicles are constantly improving, which puts forward higher requirements for the vehicle's heat dissipation efficiency and high-speed driving stability.

[0003] To meet heat dissipation requirements, existing front bumpers feature air intake grilles to guide cool external air into the engine compartment and cool the engine radiator. However, this airflow guidance method is rather crude, lacking refined management after the air enters. In particular, for the braking system, which also generates a lot of heat, the existing front bumper structure lacks dedicated, efficient directional cooling channels. Under continuous braking and high-load driving conditions, this leads to overheating and performance degradation of the braking system, affecting driving safety.

[0004] Meanwhile, in terms of aerodynamics, although some front bumpers are designed with a lower spoiler curve structure, these designs fail to be systematically integrated with the overall airflow field of the front of the car. It is difficult to effectively manage the airflow flowing above and below the front of the car to generate sufficient downforce. When the vehicle is traveling at high speed, the front of the car will experience an unstable floating sensation due to lift, which affects the precision and safety of handling. Existing technical solutions are unable to integrate and coordinate efficient multi-area heat dissipation, aerodynamic stabilization, and basic protection functions into a structural design.

[0005] Therefore, this utility model proposes a front bumper cooling fin type ventilation device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology, such as the single airflow guiding structure of the front bumper of automobiles, which makes it difficult to achieve directional and efficient heat dissipation of the engine compartment and braking system, and the poor stability at high speed due to insufficient aerodynamic design, this utility model aims to provide a front bumper heat dissipation fin type ventilation device with improved structure that can effectively solve the above problems.

[0007] This utility model provides a front bumper cooling fin type ventilation device, including: a front bumper body, on which a large-sized air intake hole and a fog light hole are opened; and a left air intake hole, a right air intake hole, a lower turbulence curve, an upper turbulence curve, a license plate mounting plate, a large protective grille, multiple small protective grilles and multiple cooling fins are further provided on the front bumper body.

[0008] The lower spoiler curve and the upper air intake curve are integrally formed at the bottom and top of the front bumper body, respectively, and the left air intake and the right air intake are opened on both sides of the top of the large-sized air intake.

[0009] Furthermore, the license plate mounting plate is fixed to the upper side of the large-sized air intake, the large protective grille is embedded and fixed inside the large-sized air intake, the multiple small protective grilles are respectively embedded and fixed inside the left air intake and the right air intake, and the multiple heat dissipation fins are disposed inside the left air intake and the right air intake, and are located downstream of the small protective grilles in the airflow direction, and are combined through the specific spatial positional relationship of the above components.

[0010] Preferably, the front bumper cooling fin type ventilation device further includes a cooling fin, which is an integrally formed or fixed to the outer surface of the front bumper body.

[0011] Preferably, both the large protective grille and the plurality of small protective grilles are mesh structures, used to provide physical protection for internal components while allowing ventilation.

[0012] Preferably, the lower spoiler curve is a lip structure extending forward and downward along the bottom end of the front bumper body.

[0013] Preferably, the upper drainage curve is a curved surface structure that curves upwards along the rear end of the top surface of the front bumper body.

[0014] Preferably, the second heat dissipation fin is a set of guide plates that are inclined along a preset airflow direction.

[0015] More preferably, the deflector is tilted towards the area where the vehicle's braking system is located, in order to achieve directional cooling.

[0016] Preferably, the second heat dissipation fin is made of an elastic material with cushioning properties.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem in the prior art that the front bumper can only utilize airflow in a single way and cannot simultaneously provide efficient directional cooling for the engine compartment and braking system by integrating a large-sized air intake hole and independent left and right air vents on the front bumper body, and by coordinating the installation of protective grille plates and heat dissipation fins for precise airflow guidance inside each air intake. This achieves the technical effect of synergistically improving the overall vehicle cooling efficiency and providing forced air cooling for the braking system to ensure the stability of braking performance.

[0019] 2. This utility model solves the problem in the prior art where the front bumper only considers aesthetics and ignores aerodynamic effects, resulting in insufficient downforce and poor stability at high speeds, by integrating an upper airflow curve and a lower airflow curve at the top and bottom of the front bumper body. It achieves the technical effect of effectively improving high-speed driving stability and handling safety by optimizing the airflow field at the front of the vehicle to generate significant downforce.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0027] Example:

[0028] Please refer to Figure 1 , Figure 2 and Figure 4As shown, the front bumper cooling fin type ventilation device includes a front bumper body 1 as the basic frame. The front bumper body 1 has a large-sized air intake 31 located on the lower side, a left air intake 32 located on the left side of the top of the large-sized air intake 31, a right air intake 33 located on the right side of the top of the large-sized air intake 31, and fog light holes 44 symmetrically opened on the left and right sides of the large-sized air intake 31. The bottom end of the front bumper body 1 is integrally formed with a lower spoiler curve 34, and the top end of the front bumper body 1 is integrally formed with an upper air intake curve 35. The front bumper cooling fin type ventilation device also includes a large-sized air intake fixed by bolts or snap-fit. The license plate mounting plate 45 on the upper side of the hole 31, and the heat dissipation fins 1 and 2 integrally formed or fixed to the outer surface of the front bumper body 1, the interior of the front bumper heat dissipation fin ventilation device is provided with a large protective grille 41, multiple small protective grilles 42 and multiple heat dissipation fins 2 43. The large protective grille 41 is embedded and fixed inside the large-sized air intake hole 31, the multiple small protective grilles 42 are respectively embedded and fixed inside the left air intake hole 32 and the right air intake hole 33, and the multiple heat dissipation fins 2 43 are set inside the left air intake hole 32 and the right air intake hole 33, and are located downstream of the multiple small protective grilles 42 in the airflow direction.

[0029] Please refer to Figure 3 and Figure 4 The protection mechanism 4 includes a large protective grille 41, multiple small protective grilles 42, and multiple cooling fins 43. Both the large protective grille 41 and the multiple small protective grilles 42 have a mesh structure. The large protective grille 41 is fixed to the inner wall of the large-sized air intake 31 by snap-fit ​​or hot-melt welding. The multiple small protective grilles 42 are fixed to the inner walls of the left air intake 32 and the right air intake 33 respectively in the same way, to block sand and gravel while allowing airflow. The multiple cooling fins 43 form a group of guide plates inclined along a preset airflow direction, with the inclined direction of the guide plates facing the area where the vehicle's braking system is located. The multiple cooling fins 43 are made of springs with buffering properties. Made of a heat-reducing material and fixedly installed inside the left air intake 32 and right air intake 33, located downstream of the small protective grille 42 in the airflow direction, the lower turbulence curve 34, which is part of the guiding mechanism 3, is a lip structure extending forward and downward along the bottom end of the front bumper body 1, and the upper turbulence curve 35 is a curved structure that curves upward along the rear end of the top surface of the front bumper body 1. The heat dissipation fin 12 is a sheet structure that is integrally formed or fixed to the outer surface of the front bumper body 1. Through this overall structure that combines the air intake, air intake, built-in grille and heat dissipation fins, and external turbulence and turbulence curves, it is ensured that the airflow can be efficiently captured, filtered, and precisely guided to the designated heat dissipation area.

[0030] As a preferred embodiment, in order to further enhance the visual performance style of the vehicle body and optimize its aerodynamic characteristics, the heat dissipation fin 2 is specifically a sheet-like structure integrally formed or bonded to the outer surfaces of the left and right sides of the front bumper body 1. The surface of the heat dissipation fin 2 may be provided with airflow guiding texture. The lower spoiler curve 34 is specifically a lip structure that is horizontally set along the entire bottom end of the front bumper body 1 and extends smoothly forward and downward. The end of the lip structure may be slightly rolled up to form a more stable airflow separation. The upper airflow guiding curve 35 is specifically a curved surface structure that smoothly curves upward along the rear end of the top surface of the front bumper body 1. The design of the curved surface structure can smoothly connect with the airflow flowing through the engine hood. The combination of the lower spoiler curve 34 and the upper airflow guiding curve 35 can jointly optimize the airflow speed and pressure distribution flowing through the upper and lower surfaces of the front of the vehicle, thereby generating stable downforce at the front of the vehicle.

[0031] As another preferred embodiment, in order to achieve reliable protection and precise heat dissipation guidance, both the large protective grille 41 and the multiple small protective grilles 42 can adopt a honeycomb or parallel grille strip mesh structure with high strength and high porosity. This structure can effectively block larger particles of sand or other road debris while ensuring maximum ventilation efficiency. The second heat dissipation fin 43 is specifically a set of guide plates that are inclined along a preset airflow direction. The inclination angle and direction of the guide plates are precisely designed through fluid dynamics simulation, so that the guided airflow outlet is directly facing the area where the vehicle's braking system is located, directly blowing on the brake calipers and brake discs to achieve forced air cooling of the braking components. Furthermore, in order to provide a buffering effect and protect the internal structure in low-speed collisions, the second heat dissipation fin 43 is preferably made of an elastic material with buffering properties, such as high-toughness reinforced polypropylene or wear-resistant thermoplastic polyurethane.

[0032] Working principle:

[0033] When the vehicle is in motion, especially at high speeds, the various components of the front bumper's finned ventilation system work together to actively manage and efficiently utilize the oncoming airflow. The process mainly involves two aspects: heat dissipation and cooling, and aerodynamic stabilization. Regarding heat dissipation, when a high-speed airflow directly impacts the front bumper body 1, the large central air intake 31 captures a large amount of air. Before entering, the air first flows through a large protective grille 41 embedded and fixed inside the large air intake 31. The mesh structure of the large protective grille 41 effectively intercepts flying debris, insects, and other road debris, forming the first physical barrier for the engine radiator and air conditioning condenser inside the vehicle, ensuring the incoming cooling air is clean and preventing the radiator fins from becoming clogged or damaged. The filtered clean airflow then enters the engine compartment, where it undergoes forced convection heat exchange with the radiator, efficiently removing heat and ensuring the normal operating temperature of the powertrain. Simultaneously, the airflow... The left air intake 32 and right air intake 33, located on both sides of the top of the large air intake 31, open up independent airflow channels specifically for cooling the braking system. When the airflow enters these two air intakes, it is first filtered and protected by multiple small protective grilles 42 embedded and fixed inside the air intakes. Then, the airflow directly impacts multiple cooling fins 43 located downstream of the airflow. These multiple cooling fins 43 act as a set of guide plates tilted along the preset airflow direction. The specific tilt angle and sheet structure regulate the potentially turbulent airflow and accelerate it towards a precise target area, namely the area directly opposite the vehicle's braking system. This forms a concentrated, high-velocity cooling air column that directly blows onto the brake calipers and brake discs, which generate a lot of heat, achieving point-to-point forced air cooling. This design greatly improves the cooling efficiency of the braking system, effectively suppresses the heat fade phenomenon caused by continuous or high-intensity braking, and ensures driving safety.

[0034] In terms of aerodynamic stability, the external contour design of the front bumper body 1 plays a crucial role. The lower spoiler curve 34 at the bottom, with its lip structure extending forward and downward, forces the airflow path towards the underside of the car to become longer and accelerate. According to Bernoulli's principle, the increased air velocity leads to a significant decrease in air pressure at the bottom of the front of the car, forming a stable negative pressure zone. Correspondingly, the upper airflow curve 35 at the top of the front bumper body 1, with its curved structure curving upward along the rear end of the top surface of the front bumper body 1, smoothly guides the airflow to the surface of the hood, maintaining a relatively stable air velocity and higher air pressure above the front of the car. The heat dissipation fins 2 on the outer surface of the front bumper body 1 also contribute to the aerodynamic stability. The lateral airflow is further optimized to improve overall aerodynamics. Ultimately, the pressure difference between the high-pressure area above the front of the car and the low-pressure area below acts on the front bumper's finned ventilation system, generating a powerful net force that presses the front of the car vertically towards the ground—the downforce. This downforce increases significantly with vehicle speed, effectively improving the adhesion between the front tires and the ground, i.e., grip. This makes the vehicle more stable and less prone to drifting when driving in a straight line at high speeds, and provides better tracking and handling limits when cornering at high speeds. The integrated design of the fog light holes 44 and the license plate mounting plate 45 ensures the functional integrity of the front bumper as a body component while achieving the above performance.
