Description

Technical Field

[0001] This utility model relates to the field of all-terrain vehicle technology, and in particular to a radiator system for an all-terrain vehicle and an all-terrain vehicle. Background Technology

[0002] With the rapid development of the all-terrain vehicle industry, large displacement and entertainment have become synonymous with the industry and are loved by consumers. However, the multi-scenario driving conditions and displacement upgrades of all-terrain vehicles bring huge challenges to the design of the vehicle cooling system.

[0003] However, the radiator is a key component of the cooling system. The radiator dissipates engine heat through heat exchange between the coolant and the air. To ensure efficient and reliable cooling systems when operating under harsh conditions with high heat loads, all-terrain vehicles typically use larger radiators or more powerful fans to guarantee sufficient airflow into the radiator core. The placement of the radiator on an all-terrain vehicle is influenced by factors such as the overall vehicle shape, rider visibility, and steering interference. Usually, the radiator is tilted above the front of the vehicle. This tilted placement reduces the radiator's frontal area and causes severe hot air backflow around the radiator, affecting the heat exchange efficiency of the cooling system. This can easily lead to a decrease in the radiator's heat dissipation efficiency, increasing the risk of coolant overheating and boiling, engine overheating and cylinder scoring, and poor engine lubrication, thus shortening the product's lifespan.

[0004] Therefore, there is a need for an all-terrain vehicle radiator system and an all-terrain vehicle that can concentrate more air in front of the radiator and flow into the radiator core, ensuring that the hot air from the radiator outlet is smoothly guided to the external environment, preventing the hot air from flowing back into the radiator, further improving the heat exchange efficiency of the cooling system, ensuring the reliability of the engine, reducing the operating cost of the radiator, and reducing production costs. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a radiator system for an all-terrain vehicle and an all-terrain vehicle, which can allow more air to be gathered in front of the radiator and flow into the radiator core, ensuring that the hot air from the radiator outlet is smoothly guided to the external environment, preventing the hot air from the radiator from flowing back, further improving the heat exchange efficiency of the cooling system, ensuring the reliability of the engine, reducing the cost of using the radiator, and reducing production costs.

[0006] This utility model provides a radiator system for an all-terrain vehicle, including a radiator and an air outlet guide plate disposed facing the radiator's air outlet surface. The air outlet guide plate is used to guide the air discharged from the radiator's air outlet surface along the lateral direction of the all-terrain vehicle. The air outlet guide plate can reduce airflow turbulence, guide airflow, ensure that the hot air generated at the radiator's air outlet surface can be effectively discharged, avoid the formation of airflow eddies, enable rapid exchange between the radiator's air outlet and the outside air, ensure that the hot air can be discharged smoothly, reduce air outlet resistance, achieve the purpose of preventing hot air backflow, and improve the heat exchange efficiency of the cooling system.

[0007] Furthermore, the air outlet guide plate is composed of a front section and a rear section. The front section of the air outlet guide plate is inclined downwards from back to front, and the rear section of the air outlet guide plate gradually decreases from the middle to both sides to form an inclined part. This effectively prevents the hot air from the heat sink outlet surface from flowing to the electrical components, reducing the risk of heat damage to the electrical components. On the other hand, it reduces the air outlet resistance, allowing the airflow from the heat sink to flow smoothly to the external environment, thereby further playing a guiding role.

[0008] Furthermore, the radiator is provided with baffles I on both sides of the air intake surface to prevent the exhaust air from entering the air intake surface; the baffle I includes a vertical surface and a baffle surface formed by the flange of the vertical surface, and the baffle surface extends laterally to the radiator; this prevents hot air from flowing from the air intake surface of the radiator into the air intake surface of the radiator through the gap in the vehicle, further reducing hot air recirculation, and at the same time reducing the ambient temperature of the air on the air intake surface of the radiator.

[0009] Furthermore, it also includes an air outlet grille, which is set on both sides of the radiator and corresponds to the air outlet surface. Each air outlet grille is provided with a baffle plate II at the top. The baffle plate II extends towards the air inlet surface of the radiator and partially overlaps with the baffle plate I. This reduces the structural gap between the air inlet surface and the air outlet surface of the radiator 2 on both sides, preventing hot air from the air outlet surface of the radiator from flowing back to the air inlet surface of the radiator through the gap. At the same time, this overlapping design allows the baffle plate I and the baffle plate II to partially overlap in space, shortening the overall installation length, improving space utilization, and achieving the best backflow prevention effect.

[0010] Furthermore, it also includes an air intake assembly corresponding to the radiator's windward side. The air intake assembly includes a front air intake grille and an upper air intake grille. The front air intake grille is located on the front side of the radiator's windward side and directs the incoming air towards the radiator. The upper air intake grille is located at the upper part of the radiator's windward side, tilted from back to front and downward, and also directs the incoming air towards the radiator. The upper air intake grille is angled to the front air intake grille, allowing more air gathered in front of the all-terrain vehicle to enter the air intake assembly, increasing the radiator's air intake volume, thereby increasing the radiator's windward area and ensuring the radiator's air intake volume.

[0011] Furthermore, the upper air intake grille features multiple grille guide vanes symmetrically arranged on both sides. The structure and arrangement of these grille guide vanes guide the air in front of the radiator and introduce it into the radiator's air intake surface. The symmetrical arrangement of the grille guide vanes integrates with the overall vehicle design, enhancing the vehicle's aesthetics and showcasing its individuality. A well-designed angle for the grille guide vanes reduces wind resistance during driving, improving the stability and fuel economy of the all-terrain vehicle. While guiding airflow, it also blocks larger particles from entering the system, providing protection and ensuring smooth engine operation and efficiency.

[0012] Furthermore, the left and right ends of the upper air intake grille are bent downwards to form wind deflectors, and the shape of the front end is consistent with the shape of the front air intake grille to form a connection. The wind deflectors prevent the airflow entering the front of the radiator from leaking. The wind deflectors can guide the airflow and reduce turbulence. At the same time, they match the shape of the front air intake grille to form a continuous airflow guide surface. Through the consistent connection of geometric shapes, the air resistance during driving is reduced and the structural strength of the air intake assembly is improved.

[0013] Furthermore, the height of the front air grille is 40%-50% of the height of the space occupied by the radiator; while ensuring the air intake of the radiator, it prevents foreign objects such as stones and flying insects from hitting the radiator and other components, reducing the risk of mechanical damage.

[0014] This utility model also provides an all-terrain vehicle, which is equipped with the radiator system of the all-terrain vehicle described above; it reduces the air intake temperature of the radiator air intake surface, effectively improves the heat exchange efficiency of the cooling system, ensures the working reliability of the engine, reduces the use cost of the radiator, and reduces production cost.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a radiator system for an all-terrain vehicle and an all-terrain vehicle. By setting an air outlet guide plate on the radiator's air outlet surface, the airflow from the radiator is controlled, preventing hot air from flowing directly onto electrical components, reducing the risk of thermal damage to these components, and reducing airflow resistance. This guides the hot air passing through the radiator's air outlet surface to the external environment, achieving the purpose of preventing hot air backflow. An air intake component is set on the radiator's windward side, which expands the effective air intake area of ​​the radiator during driving, increasing the air intake volume, and preventing foreign objects from entering and damaging the radiator, thus affecting heat exchange efficiency. Wind baffles I and II set on both sides of the radiator's lateral sides effectively block the airflow at the air inlet and outlet surfaces, further optimizing hot air backflow, reducing the air inlet temperature at the radiator's air inlet surface, effectively improving the heat exchange efficiency of the cooling system, ensuring engine reliability, reducing radiator operating costs, and reducing production costs.

[0023] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0024] This embodiment discloses a radiator system for an all-terrain vehicle, including a radiator 2 and an air outlet guide plate 4 disposed facing the air outlet surface of the radiator 2. The air outlet guide plate 4 is used to guide the air discharged from the air outlet surface of the radiator 2 along the lateral direction of the all-terrain vehicle 1. As shown in the figure, the radiator 2 is disposed above the front of the all-terrain vehicle 1 from rear to front and downward. The heat insulation plate 13 is disposed on the lower side behind the radiator 2 and connected to the radiator 2. The instrument assembly 14 is disposed behind the heat insulation plate 13. There is a space between the instrument assembly 14 and the heat insulation plate 13 for the installation of the air intake and exhaust assembly 15 and the water tank 16. This is an existing connection structure and will not be described in detail here. A fan 11 is installed on the air outlet of the radiator 2. The fan 11 enhances the heat dissipation effect of the radiator 2 by accelerating airflow. During driving, air enters from the air inlet of the radiator 2, undergoes heat exchange in the radiator 2, and is discharged from the air outlet of the radiator 2. This will not be described in detail here. The air outlet guide plate 4 is installed on the cargo frame 12 and the heat insulation plate 13 and is located on the lower side of the radiator 2. The front side of the air outlet guide plate 4 utilizes the existing front mounting lug on the cargo frame 12 and has an opening structure designed on the mounting lug. A rubber ring 45 is installed on the opening structure of the mounting lug, and a round hole is provided inside the rubber ring 45. Connecting columns extending forward are respectively provided on the left and right sides in front of the air outlet guide plate 4. Installation can be achieved by inserting the connecting post into the round hole of the rubber ring 45. The rear side of the air outlet guide plate 4 can be connected to the heat insulation plate 13 by bolts or positioning posts. The lower part of the air outlet guide plate 4 is snapped into the carrying frame 12, which can achieve quick installation of the air outlet guide plate 4. It will not be described in detail here. The setting of the air outlet guide plate 4 can reduce airflow turbulence, guide airflow, and ensure that the hot air generated by the air outlet surface of the radiator 2 can be effectively discharged, avoiding the formation of vortices in the airflow, enabling the air outlet of the radiator 2 to exchange quickly with the outside air, ensuring that the hot air can be discharged smoothly, reducing the resistance of the air outlet, achieving the purpose of preventing hot air backflow, and improving the heat exchange efficiency of the cooling system.

[0025] In this embodiment, the air outlet guide plate 4 is composed of a front section 41 and a rear section 43. The front section 41 is inclined from back to front and downward, and the rear section of the air outlet guide plate 4 gradually decreases from the middle to both sides to form an inclined part. When the all-terrain vehicle 1 is driving in a mud scene, the engine is in a low-speed, high-torque driving state most of the time. At this time, the cooling of the coolant mainly relies on the rotation of the fan 11 to remove heat. Therefore, in order to ensure that the fan 11 performs well, the front section 41 of the guide plate and the fan 11 should maintain a sufficient gap, thereby reducing the air outlet resistance of the radiator 2 to a large extent. When the front section 41 of the air guide plate is inclined from back to front and downward, the heat generated by the rotation of the fan 11 can be maximized by the inclined setting of the front section 41 of the air guide plate, so that the air outlet air guide plate 4 and the fan 11 can be effectively discharged along the arrangement structure of the front section 41 of the air guide plate. The left and right sides of the front section 41 of the air guide plate are respectively provided with clearance holes 44 to facilitate the setting of the inlet pipe 21 and the outlet pipe 22 of the heat sink 2. The front side of the rear section 43 of the air deflector is provided with two inclined surfaces 42. The two inclined surfaces 42 gradually decrease from the middle to both sides and are inclined downward. They are used to connect the front section 41 and the rear section 43 of the air deflector to form the transition section of the air outlet air deflector 4. They mainly undertake the task of airflow integration and diversion. Through the design of a specific arc, the pressure distribution of the airflow is balanced, and the continuity of the flow direction is optimized. The airflow can be guided to flow along a predetermined path. The rear section 43 of the air deflector gradually decreases from the middle to both sides to form an inclined setting and an inclined part. This inclined setting can effectively guide the airflow. By making the rear section 43 of the air deflector gradually decrease from the middle to both sides, a smooth airflow transition zone is created to ensure that the hot air from the air outlet of the radiator 2 is smoothly guided to the external environment. Due to structural limitations, all-terrain vehicles 1 often have a series of electrical components arranged below the air outlet of the radiator 2, making the structure compact. However, this arrangement can easily cause hot air from the radiator 2 to blow onto the electrical components, increasing the risk of heat damage to the components. The air outlet deflector 4 effectively prevents hot air from the air outlet of the radiator 2 from flowing onto the electrical components, reducing the risk of heat damage to the components. On the other hand, it reduces the air outlet resistance, allowing the airflow from the radiator 2 to flow smoothly to the external environment, thereby further playing a guiding role.

[0026] In this embodiment, the radiator 2 is provided with baffle plates I3 on ​​both sides of the air inlet surface to prevent the exhaust air from entering the air inlet surface; the baffle plate I3 includes a vertical surface and a baffle surface formed by the flange of the vertical surface, and the baffle surface extends laterally to the radiator 2; the baffle plates I3 are arranged on the left and right sides of the air inlet surface of the radiator 2. This arrangement can reduce the gap between the air inlet surface and the exhaust surface of the radiator 2. When the all-terrain vehicle 1 is driving, it prevents the hot airflow from the exhaust surface of the radiator 2 from flowing into the air inlet surface of the radiator 2 through the gap in the vehicle, further reducing the hot air recirculation, and at the same time reducing the ambient temperature of the air at the air inlet surface of the radiator 2.

[0027] In this embodiment, an air vent grille is also included. The air vent grille is disposed on both sides of the radiator 2 and corresponds to the air vent surface. A baffle plate II is disposed on the upper part of the air vent grille. The baffle plate II extends towards the air inlet surface of the radiator 2 and partially overlaps with the baffle plate I3. The lower part of the air vent grille is provided with air outlets corresponding to the air vent guide plate 4. As shown in the figure, two air vent plates are disposed at the lower part of the air vent grille. The two air vent plates are inclined downwards from back to front and spaced apart. This arrangement facilitates the exhaust of air directed by the air vent guide plate 4 outside the vehicle. In this embodiment, the air vent grille includes a left air vent grille 5 and a right air vent grille 6. The left air vent grille 5 and the right air vent grille 6 are respectively disposed on the left and right sides of the air vent guide plate 4 and connected to the load-bearing frame 12. The wind baffle II includes a left wind baffle 51 and a right wind baffle 61. The left wind baffle 51 is positioned above the air outlet of the left air outlet grille 5, and the right wind baffle 61 is positioned above the air outlet of the right air outlet grille 6. This allows the wind baffle II to extend towards the air inlet surface of the radiator 2 and partially overlap with the wind baffle surface of the wind baffle I3. The partially overlapping area always covers both sides of the air inlet and outlet surfaces of the radiator 2 in the horizontal direction, thereby reducing the structural gaps between the air inlet and outlet surfaces of the radiator 2. This prevents hot air from the outlet surface of the radiator 2 from flowing back to the air inlet surface of the radiator 2 through the gaps. At the same time, this overlapping design allows the wind baffle I3 and the wind baffle II to partially overlap in space, shortening the overall installation length, improving space utilization, and achieving the best anti-backflow effect.

[0028] In this embodiment, an air intake assembly is also included, corresponding to the windward side of the radiator 2. The air intake assembly includes a front air intake grille 10 and an upper air intake grille 9. The front air intake grille 10 is located on the front side of the windward side of the radiator 2 and directs the air intake towards the radiator 2. The upper air intake grille 9 is located at the upper part of the windward side of the radiator 2, tilted from back to front and downward, and directs the air intake towards the radiator 2. As shown in the figure, the front air intake grille 10 is tilted from back to front and downward at an angle to the upper air intake grille 9. The front air intake grille 10 is vertically located at the front end of the radiator 2. The angle refers to the front air intake grille 10 being at an angle to the upper air intake grille 9. The plane where the upper air intake grille 9 is installed forms an angle with the plane where the upper air intake grille 9 is installed. The angle between the upper air intake grille 9 and the front air intake grille 10 allows more air gathered in front of the all-terrain vehicle 1 to enter the air intake component, increasing the air intake volume of the radiator 2, thereby increasing the frontal area of ​​the radiator 2 and ensuring the air intake volume of the radiator 2. A protective cover 17 is provided above the upper air intake grille 9. The air intake port of the air intake component is located on the lower side of the protective cover 17 for air intake or exhaust. When necessary, it is also convenient to remove the protective cover 17 to replenish the coolant of the radiator 2. This will not be described in detail here.

[0029] 6. In this embodiment, multiple grille guide vanes 91 are symmetrically arranged on both sides of the upper air intake grille 9. The structure and arrangement of the grille guide vanes 91 allow air in front of the external radiator 2 to be guided and introduced into the air intake surface of the radiator 2. The symmetrical arrangement of the grille guide vanes 91 can be integrated with the overall vehicle design, enhancing the overall aesthetics of the vehicle and highlighting its individuality. In this embodiment, the angle formed between the grille guide vanes 91 and the horizontal plane is 25°-35°. This angle range helps to balance airflow guidance efficiency and wind resistance control. A smaller angle may lead to increased airflow separation, while an excessively large angle will increase the frontal windward area. Both may disrupt the stability of the flow field and increase drag. By reasonably setting the angle of the grille guide vanes 91, wind resistance can be reduced during driving, improving the stability and fuel economy of the all-terrain vehicle 1. While guiding airflow, it can also block larger particles from entering the system and provide protection, ensuring smooth engine operation and working efficiency.

[0030] In this embodiment, the left and right ends of the upper air intake grille 9 are bent downward to form wind deflectors 92, and the shape of the front end is consistent with the shape of the front air intake grille 10 to form a connection. The wind deflectors 92 extending downward in an arc shape at the left and right ends are integrally formed with the upper air intake grille 9, which reduces the number of parts of the all-terrain vehicle 1 while ensuring structural strength. The setting of the wind deflectors 92 avoids the leakage of airflow entering the front of the radiator 2, which would reduce the air volume. The upper air intake grille 9 can be connected by snap-fit ​​or bolts, for example, which will not be described in detail here. The wind deflectors 92 formed by bending downward at the left and right ends can guide the airflow and reduce the generation of turbulence. At the same time, they match the shape of the front air intake grille 10 to form a continuous airflow guide surface. Through the consistent connection of geometric shapes, the air resistance during driving is reduced and the structural strength of the air intake assembly is improved.

[0031] In this embodiment, the height of the front air grille 10 is 40%-50% of the height of the space occupied by the radiator 2. As an important cover at the front of the all-terrain vehicle 1, the front air grille 10 needs to have a certain impact resistance. The 40%-50% opening ratio ensures air intake efficiency while maintaining the mechanical strength of the air intake grille and surrounding support structure. The air intake grille corresponding to this ratio range matches the layout of the radiator 2 in this embodiment, which facilitates the daily cleaning and maintenance of the radiator 2 without excessively affecting the installation space of other components. If the vertical height of the front air grille 10 is greater than 50% of the horizontal height of the radiator 2, for example, excessively affecting the setting of the upper air intake grille 9, thereby reducing the air intake of the radiator 2, it is easy to generate vortices in the area in front of the radiator 2, which will disrupt the stability of the airflow. If the vertical height of the front air grille 10 is less than 40% of the horizontal height of the radiator 2, it is easy to cause uneven airflow distribution in the local area in front of the radiator 2, so that the efficiency, energy economy and styling engineering of the radiator 2 cannot achieve a balance, which is in line with the mechanical heat dissipation principle. In this embodiment, the preferred height of the front air grille 10 is 45% of the horizontal height of the radiator 2, so that the effective opening area of ​​the front air grille 10 occupies 20%-30% of the air intake surface area of ​​the radiator 2 core. This effectively ensures that the airflow on the air intake surface of the radiator 2 is evenly covered, ensuring that the airflow of the radiator 2 is uniform while preventing foreign objects such as stones and flying insects from hitting the radiator 2 and other components, thus reducing the risk of mechanical damage.

[0032] This utility model also provides an all-terrain vehicle 1, on which a radiator 2 assembly as described above is installed. An air outlet guide plate 4 is provided on the air outlet surface of the radiator 2 to control the airflow from the radiator 2, preventing hot air from flowing towards other electrical components, reducing the risk of heat damage to these components, and reducing airflow resistance. This directs the hot air from the radiator 2 outlet surface towards the external environment, preventing hot air backflow. An air intake assembly is provided on the windward side of the radiator 2, which expands the air intake area and increases the airflow volume during driving, preventing foreign objects from entering and damaging the radiator 2, thus affecting heat exchange efficiency. The baffle plates I3I and I3II arranged on both sides of the radiator 2 in the horizontal direction effectively block the air inlet and outlet surfaces of the radiator 2, thereby blocking the airflow, further optimizing the hot air recirculation phenomenon, reducing the air inlet temperature of the radiator 2, effectively improving the heat exchange efficiency of the cooling system, ensuring the reliability of the engine, reducing the operating cost of the radiator 2, and reducing production costs.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
