Description

Technical Field

[0001] This application relates to the field of motorcycle technology, and in particular to a high-efficiency heat dissipation component and a motorcycle. Background Technology

[0002] With the high-quality development of the motorcycle industry, large displacement and recreational features have become synonymous with leisure motorcycles, making them popular among consumers. However, the diverse driving conditions and increased displacement pose significant challenges to the design of the vehicle's cooling system. Insufficient airflow into the radiator can lead to excessively high coolant temperatures during engine operation, which can affect the engine's lifespan over time.

[0003] To ensure sufficient cooling airflow for motorcycles operating under harsh heat loads, current large-displacement motorcycles typically feature larger radiators or more powerful, larger diameter fans from the outset. However, they often neglect to control the airflow at the front of the radiator to effectively increase the airflow into the radiator core. This results in lower coolant temperature under normal operating conditions, affecting engine thermal efficiency and increasing costs. Furthermore, there is significant hot air backflow around the radiator, impacting the heat exchange efficiency of the cooling system.

[0004] Therefore, in view of the above-mentioned technical problems, how to increase the cooling air volume of the radiator and improve the hot air recirculation phenomenon of the radiator is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a high-efficiency heat dissipation component and motorcycle, which can increase the cooling air volume of the radiator, reduce the coolant temperature, improve the hot air recirculation phenomenon of the radiator, and enhance the heat exchange effect of the radiator.

[0006] To achieve the above objectives, this application provides a high-efficiency heat dissipation component, comprising:

[0007] A radiator is located between the front fender of a motorcycle and the engine cylinder. The radiator includes a heat dissipation core and water collection chambers located at both ends of the heat dissipation core. The upper and lower sides of the heat dissipation core are provided with an upper side plate and a lower side plate that are fixedly connected to the two water collection chambers.

[0008] Side guide vanes are located on both sides of the front end of the radiator. The two side guide vanes are respectively connected to the front end of the motorcycle's center fairing. The rear end of the side guide vanes extends to the water collection chamber. A filler is installed in the gap between the water collection chamber and the rear end of the side guide vanes.

[0009] The upper air deflector is located on the upper side of the front end of the radiator. The rear end of the upper air deflector extends toward the upper side plate, and the front end of the upper air deflector extends toward the front end of the motorcycle, forming an upper and lower air deflector pattern with the front fender.

[0010] Wherein, the lower side plate is disposed close to the front fender, and the two side deflectors, the upper deflector and the front fender enclose a "mouth"-shaped flow guiding channel.

[0011] Preferably, the upper deflector is mounted on the front shock absorber of the motorcycle through a mounting member. The upper deflector includes a first upper deflector and a second upper deflector mounted on the mounting member. The first upper deflector is located at the front end of the second upper deflector. The first upper deflector receives the air flow on the lower side of the headlight in front of the motorcycle head, and the second upper deflector is used to guide the air flow into the radiator core.

[0012] Preferably, the front end of the lower side plate extends towards the front fender, extends to protrude beyond the radiator core and is at least flush with the front end face of the water collecting chamber to receive the air flow in the flow guiding channel.

[0013] Preferably, the opposite sides of the two side deflectors are smooth surfaces, and the filling member is a flexible and compressible material.

[0014] Preferably, it further includes:

[0015] A fan, disposed on one side of the rear end of the radiator and located between the radiator and the engine cylinder. The fan blows air towards the lower part of the motorcycle chassis, and the other end of the rear side of the radiator blows air towards the engine cylinder side;

[0016] A heat insulation and flow guiding rubber sheet, the front end of which is disposed on the upper side plate, extends towards the engine cylinder side at the rear end, and covers the top of the engine cylinder along the head cover and the intake valve body of the engine bar.

[0017] Preferably, the extending side of the heat insulation and flow guiding rubber sheet is located between the engine cylinder and the air filter, and the end of the heat insulation and flow guiding rubber sheet faces the motorcycle chassis.

[0018] Preferably, the front end of the heat insulation and flow guiding rubber sheet extends beyond the radiator by 2 - 4 cm, and the left and right sides of the heat insulation and flow guiding rubber sheet are kept the same width as the radiator core.

[0020] Preferably, the fan includes a fan cover and fan blades. The fan cover is mounted on the rear end of the radiator and is fixedly connected to the radiator through a plurality of positioning points on the outer periphery of the fan cover.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 As shown, in this embodiment, a high-efficiency heat dissipation component is provided, including a radiator 1, a side guide plate 2, and an upper guide plate. The radiator 1 is a conventional radiator 1 found in existing motorcycles, and it is located between the front fender 8 and the engine cylinder 14 of the motorcycle. Please refer to... Figure 3, the radiator 1 includes a radiator core 9 and water collecting chambers 10 provided at both ends of the radiator core 9. The two water collecting chambers 10 are used to supply refrigerant to the radiator core 9 and recover the refrigerant after heat exchange. Upper side plates 11 and lower side plates 12 for fixedly connecting the two water collecting chambers 10 are provided on the upper and lower sides of the radiator core 9. The upper side plates 11, the lower side plates 12 and the water collecting chambers 10 form a stable fixed connection structure, and cooperate with the radiator core 9 to form a complete structure of the radiator 1.

[0041] The side deflectors 2 are located on both sides of the front end of the radiator 1. Please refer to Figure 1 and Figure 5 , the two side deflectors 2 are respectively connected to the front end of the middle fairing (not shown in the figure) of the motorcycle for transition. It can be understood that the two side deflectors 2 cooperate with the middle fairing to increase the wind-breaking effect and reduce the aerodynamic resistance. The rear end of the side deflector extends to the water collecting chamber 10, and there is a gap of 10 - 15 mm between the rear end of the side deflector and the water collecting chamber 10, and a filling member 3 is assembled at this gap.

[0042] The filling member 3 is a flexible and compressible material, such as heat-insulating sponge, etc. The filling member 3 is pasted on the water collecting chamber 10 to fill the assembly gap between the side deflector 2 and the water collecting chamber 10, which can avoid the vibration problem of the side deflector 2 during driving and provide a buffer zone between the side deflector 2 and the radiator 1. Under the action of the side deflector 2, the hot air reflux on both sides of the radiator 1 can be avoided, the wind-accumulating effect on both sides of the radiator 1 can be increased, and the air intake volume of the radiator 1 and the heat exchange efficiency of the cooling system can be improved.

[0043] The upper deflector is located on the upper side of the front end of the radiator 1. Please refer to Figure 1 and Figure 7 , the rear end of the upper deflector extends towards the upper side plate 11, and the front end of the upper deflector extends towards the front end of the motorcycle, so as to cooperate with the front fender 8 to form an upper and lower air guiding form, increase the upper and lower wind-accumulating effect of the radiator 1, and improve the air intake volume of the radiator 1.

[0044] On this basis, the lower side plate 12 of the radiator 1 can be arranged close to the front fender 8, so that the two side deflectors 2, the upper deflector and the front fender 8 enclose a "mouth"-shaped air guiding channel, which is beneficial to the convergence of the front cooling air flow into the radiator core 9 for heat exchange, avoid the problems of hot air reflux of the radiator 1 and insufficient cooling performance, ensure the working reliability of the engine, and reduce the use cost of the radiator 1. [[ID=二十一]] [[ID=二十二]]

[0045] [[ID=二十三]]In addition, to improve the smoothness of the air flow in the "mouth"-shaped air guiding channel, the opposite sides of the two side deflectors 2 can be set as smooth surfaces, and the inner wall surface of the upper deflector can be set as a smooth surface. [[ID=二十四]] [[ID=二十五]]

[0046] In summary, this application forms a "U"-shaped airflow channel in front of the radiator 1 by means of two side guide plates 2, an upper guide plate, and a front fender 8. This allows the cooling air brought by the motorcycle's speed to be fully injected into the radiator 1, improving the utilization rate of the cooling airflow, ensuring engine reliability, and extending engine life. At the same time, the two side guide plates 2 and the upper guide plate can also prevent severe hot air backflow around the radiator 1, improve the heat exchange efficiency of the cooling system, enhance the cooling capacity of the radiator 1, and reduce the cost of the radiator 1.

[0047] Since the upper air deflector is located on the upper front side of the radiator 1, which roughly corresponds to the position of the motorcycle's front shock absorber, it can be mounted on the motorcycle's front shock absorber using mounting piece 5. Please refer to [reference needed]. Figure 1 Mounting component 5 is installed on the front shock absorber of the motorcycle, thereby fixing the upper deflector in place. In addition, considering the issues of shock absorption and ease of installation, the upper deflector can be split into two parts, namely, the upper deflector includes a first upper deflector 6 and a second upper deflector 7. Both can be installed on mounting component 5 with bolts. The first upper deflector 6 is located at the front end of the second upper deflector 7. The first upper deflector 6 receives the airflow below the front headlight of the motorcycle, while the second upper deflector 7 is used to guide the airflow into the heat dissipation core 9. The two parts work together to guide the airflow inside the front of the motorcycle and reduce turbulence loss.

[0048] Additionally, since the lower side plate 12 is located close to the front fender 8, to prevent excessive airflow from escaping through the gap between them, the front end of the lower side plate 12 can extend towards the front fender 8, extending to protrude from the heat dissipation core 9 and at least flush with the front end face of the water collection chamber 10. Please refer to [reference needed]. Figure 4 The dotted line section of the lower middle side plate 12 helps to receive more cooling airflow from the front into the heat dissipation core 9, thereby increasing the air intake of the radiator 1.

[0049] There are generally two methods for controlling the high-temperature airflow at the rear of traditional motorcycle radiators: one is to design radiator vents directly on the side covers, and the other is to add a fan shroud for directional control. Both existing technologies primarily consider smooth airflow from the cooling system, but do not adequately address the motorcycle's thermal comfort. At idle or low-to-medium speeds, the high-temperature airflow from the sides of the radiator easily flows towards the rider's calves and feet, causing intense heat sensation. Therefore, this application can also modify the path of the high-temperature heat flow using the fan 4 and the heat-insulating guide rubber 18, thereby improving the rider's thermal comfort.

[0050] Specifically, the high-efficiency heat dissipation component of this application also includes a fan 4 and a heat-insulating and air-guiding rubber sheet 18, please refer to... Figure 8The fan 4 is located on one side of the rear end of the radiator 1, between the radiator 1 and the engine cylinder 14. The fan 4 exhausts air downwards towards the chassis of the motorcycle, while the other end of the rear side of the radiator 1 exhausts air towards the engine cylinder 14. The exhaust temperature of the radiator 1 can reach over 100℃. Designing the exhaust path of the fan 4 entirely downwards and placing it on the left or right side of the radiator 1 allows the other side of the radiator 1 to remain open, which helps to avoid the fan 4 obstructing the airflow from the radiator 1 and reduces the airflow resistance. Since part of the airflow from the radiator 1 is exhausted downwards by the fan 4, the high-temperature airflow is reduced from blowing onto the rear cover, electrical components, and the rider's legs and feet, reducing the risk of heat damage and improving riding comfort at idle or low to medium speeds.

[0051] The front end of the heat-insulating and flow-guiding rubber sheet 18 is located on the upper side plate 11. Please refer to... Figure 8 and Figure 9 The heat-insulating guide rubber 18 extends towards the engine cylinder 14 from its rear end and covers the top of the engine cylinder 14 along the engine block cover 15 and the intake valve body 16. Furthermore, the extended side of the heat-insulating guide rubber 18 is located between the engine cylinder 14 and the air filter 17, with its end facing the motorcycle chassis. The heat-insulating guide rubber 18 forcibly directs the high-temperature airflow downwards to be discharged from the chassis, while simultaneously reducing heat transfer from the high-displacement, high-heat engine to the air filter 17's intake pipe, thus preventing excessively high intake temperatures from the air filter 17 and affecting the overall vehicle performance.

[0052] Please refer to Figure 9 The front end of the heat-insulating and heat-conducting rubber strip 18 rests on the upper side plate 11 of the radiator 1, and the front end of the heat-insulating and heat-conducting rubber strip 18 extends 2-4 cm beyond the radiator 1. Figure 9 The dotted line on the left represents the portion of the heat-insulating guide rubber 18 that extends beyond the radiator 1, covering the engine cylinder 14's cover 15 and intake valve body 16, and extending to the rear of the cylinder block, covering most of the cylinder block. The left and right sides of the heat-insulating guide rubber 18 maintain the same width as the radiator core 9, ensuring that airflow can be fully discharged to the chassis along the defined path of the heat-insulating guide rubber 18. Of course, the arrangement of the heat-insulating guide rubber 18 includes, but is not limited to, the method given in this application, as long as it ensures that heat flow can be discharged from the channel between the engine cylinder 14 and the air filter 17 along a preset path and discharged to the chassis. No further restrictions are imposed here, and all fall within the protection scope of this application.

[0053] Please also refer to Figure 6 A support lug 13 is provided on the upper side plate 11, and the front end of the heat insulation and flow guiding rubber 18 is fixed by the support lug 13; please refer to Figure 9The middle or rear end of the heat insulation guide rubber 18 is pressed tightly against the intake valve body 16 through the air filter 17. The "one in front and one behind" fixing method prevents the heat insulation guide rubber 18 from moving due to vehicle vibration during vehicle use.

[0054] Furthermore, the above indicates that fan 4 can exhaust air downwards, meaning the heat is ultimately expelled from the motorcycle's chassis. For details, please refer to... Figure 10 and Figure 11 Fan 4 includes a fan shroud 19 and fan blades 20. The fan shroud 19 is installed at the rear of the heatsink 1. Please refer to [reference needed]. Figure 2 and Figure 10 The fan 4 is fixedly connected to the heat sink 1 through multiple positioning points on the outer periphery of the fan cover 19. The multiple positioning points can be fixed to the heat sink 1 in the form of bolt holes and bolts. The fixed connection with the fan cover 19 can be achieved by adding a fixing bracket on the water collection chamber 10.

[0055] The front end of the fan shroud 19 faces the heat sink 9, and the fan blades 20 can be embedded in the front end of the fan shroud 19. The rear end of the fan shroud 19 is a closed design to prevent heat from being discharged from the fan shroud 19 to the engine cylinder 14. An opening is provided on the lower side of the fan shroud 19. After the airflow exchanges heat with the radiator 1, the power of the rotating fan blades 20 drives the heat flow to be discharged through the opening of the fan shroud 19. The specific airflow path can be seen from [reference needed]. Figure 11 And eventually discharged into the chassis of the motorcycle.

[0056] This application utilizes the unique design of the fan 4, along with the heat-insulating and air-guiding rubber 18 above and behind the radiator 1, to prevent excessive hot airflow from the radiator 1 from blowing onto the rear cover, electrical components, and the rider's legs and feet, thereby reducing the risk of heat damage and improving the riding comfort of the motorcycle. At the same time, it can reduce the heat transfer from the high-displacement, high-heat engine to the air filter 17 intake pipe, preventing the air filter 17 intake temperature from becoming too high and affecting the overall power performance of the motorcycle.

[0057] This application also provides a motorcycle that includes the aforementioned high-efficiency heat dissipation components, as well as other necessary components that make up the motorcycle, which will not be described in detail here, but can be referred to in the prior art.

[0058] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0059] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
