Description

Technical Field

[0001] This utility model belongs to the field of motorcycle thermal management technology, specifically relating to an arc-shaped radiator for motorcycles. Background Technology

[0002] Traditional sportbike radiators are mostly flat or in-line structures, which have the following problems:

[0003] 1. Limited heat dissipation efficiency: The surface area of ​​the flat heat sink is limited, resulting in low airflow utilization during high-speed riding, which can easily lead to engine overheating;

[0004] 2. Handling conflict: The large lateral dimension of the inline radiator encroaches on the front wheel steering space, limits the maximum steering angle, and increases the minimum turning radius;

[0005] 3. Insufficient passability: The radiator protrudes from the bottom, reducing the vehicle's ground clearance and making it prone to scraping when traversing rough roads.

[0006] Existing technologies lack solutions that balance heat dissipation performance and motion control, and there is an urgent need for an innovative structural design. Utility Model Content

[0007] The purpose of this utility model is to provide an arc-shaped radiator for motorcycles, which increases the heat dissipation area through the arc-shaped curved surface structure and optimizes the aerodynamic layout to improve steering performance and passability. It is an innovative design of cooling system for sport motorcycles.

[0008] The specific technical solution adopted by this utility model is as follows:

[0009] A motorcycle arc-shaped radiator includes a C-shaped continuous arc-shaped body, uniformly distributed heat sinks and cooling fans, with multiple heat sinks and cooling fans fixedly arranged on the front side of the arc-shaped body, and multiple mounting brackets fixedly arranged on the outer side of the arc-shaped body.

[0010] Furthermore, the bottom of the arc-shaped main body has an upward-curving structure, and the upward-curving angle of the bottom of the arc-shaped main body is 10° to 20°, with a ground clearance of ≥180mm.

[0011] Furthermore, the radius of curvature of the arc-shaped main body is R = 150~300mm.

[0012] Furthermore, the arc-shaped main body, heat sink, and mounting bracket are all made of 6061-T6 aluminum alloy, with an overall weight of ≤2.5kg.

[0013] The technical effects achieved by this utility model are as follows:

[0014] 1. Heat dissipation performance: At a wind speed of 80km / h, the heat dissipation power reaches 4.2kW, which is 40% higher than the traditional design;

[0015] 2. Handling: The minimum turning radius is reduced by 18%, significantly improving steering agility;

[0016] 3. Lightweight and durable: Weighing only 2.3kg, it passed the 720h salt spray test without corrosion.

[0017] This invention, through its arc-shaped curved surface structure, aerodynamic guidance, and upturned bottom design, achieves a first-ever synergistic optimization of heat dissipation performance and handling in the field of sportbikes. It solves the pain points of traditional radiators, such as low thermal efficiency, limited steering, and poor passability, and is particularly suitable for track racing and complex road conditions.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-2 As shown, a curved radiator for motorcycles includes a C-shaped continuous curved body 1, uniformly distributed heat sink 2, and a cooling fan 4. The heat sink 2 is uniformly distributed along the curved surface, increasing the total heat dissipation area by 35% to 50% compared to a flat radiator. The curved airflow design guides high-speed airflow to the gaps between the heat sink 2, increasing the airflow speed by 20% and improving the heat dissipation efficiency by 30%. Multiple heat sinks 2 and cooling fans 4 are fixedly installed on the front side of the curved body 1. Multiple mounting brackets 3 are fixedly installed on the outer side of the curved body 1, and the radiator is fixed to the frame by the multiple mounting brackets 3 during installation.

[0024] The bottom of the arc-shaped main body 1 has an upward-curving structure, and the upward angle of the bottom of the arc-shaped main body 1 is 10°~20°. The ground clearance is ≥180mm, which makes the vehicle passability meet the requirements of off-road tracks. The radiator narrows inward on both sides, reducing the width by 15% to avoid interference with the front wheel steering mechanism. The maximum steering angle is increased by 8°, and the minimum turning radius is reduced to 2.8m.

[0025] The radius of curvature of the arc-shaped main body 1 is R = 150~300mm, which matches the streamline of the front fairing.

[0026] The arc-shaped main body 1, heat sink 2, and mounting bracket 3 are all made of 6061-T6 aluminum alloy, with an overall weight of ≤2.5kg, a 10% reduction in overall weight. They are made of 6061-T6 aluminum alloy and vacuum brazing process, with a strength of ≥300MPa.

[0027] Example 1:

[0028] Structural manufacturing:

[0029] 1. Use a CNC bending machine to bend the aluminum alloy substrate into a C-shaped arc body 1 with a radius of curvature R = 200mm;

[0030] 2. Fix the heat sink 2 by laser welding, with a spacing of 2.5mm between the sinks and a height of 30mm, for a total of 120 sinks;

[0031] 3. The bottom is tilted upwards at an angle of 15°, and the ground clearance is set at 180mm.

[0032] Example 2:

[0033] Installation and compatibility:

[0034] 1. The radiator is fixed to the front of the vehicle frame by a bracket, with a distance of ≥10mm between it and the inner wall of the fairing to ensure unobstructed airflow.

[0035] 2. The cooling pipes are arranged along the inner side of the arc to reduce bending resistance.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
