Description

Technical Field

[0001] The present invention relates to the technical field of anti-deposition devices, and in particular to a high-efficiency composite radiator. Background Art

[0002] The radiator is a very important component in the cooling system of an internal combustion engine. It is a thin-walled component manufactured using a soft soldering process. Its function is to transfer the heat dissipated by the engine to the surrounding atmosphere.

[0003] Existing radiators install a detachable filter device at the front end of the thin-walled component to facilitate cleaning or prevent flocs, branches and leaves, and dead insects from accumulating on the surface of the thin-walled component of the radiator. However, after the dense mesh structure is installed on the filter device, it will affect the speed at which gas enters the thin-walled component to a certain extent, reducing the stability of the radiator's heat dissipation. Moreover, although the filter device is convenient for subsequent cleaning after flocs, branches and leaves, dead insects and other debris accumulate on the surface of the filter mesh, the impact on the heat dissipation efficiency of the heat dissipation device still exists. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art that the installation of a filter device affects the heat dissipation stability of the radiator and that the heat dissipation stability is still reduced after debris adheres to the surface of the filter device, and to propose a high-efficiency composite radiator.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: The fins of the heat dissipation device are connected to the heat dissipation device by a threaded connection, and the fins are connected to the heat dissipation device by a threaded connection. The fins are connected to the heat dissipation device by a threaded connection. The fins are connected to the heat dissipation device by a threaded connection.

[0006] Preferably, the thin-wall heat dissipation component includes a heat dissipation grid frame, one end of the overflow connection cover is sleeved on the surface of the heat dissipation grid frame, a wing heat sink is fixed inside the grille of the heat dissipation grid frame, a circulation component is provided on one side of the heat dissipation grid frame, a fixing component is provided on the heat dissipation grid frame, an air inlet drainage pipe is fixed to the liquid inlet of the heat dissipation grid frame, and an air outlet drainage pipe is fixed to the liquid outlet of the heat dissipation grid frame.

[0007] Preferably, the circulation component includes a circulation pipe fixed to the side of the heat dissipation grid frame, and the circulation pipe is connected to the heat dissipation grid frame.

[0008] Preferably, the fixing assembly includes positioning plates fixed to both sides of the heat dissipation grid frame, and fixing bolts are inserted into the inner walls of the positioning plates.

[0009] Preferably, the limiting assembly includes a limiting ring fixed to the inner side wall of the overflow connection cover, and one end of the limiting ring is tightly fitted to the surface of the heat dissipation grid frame.

[0010] Preferably, the traction assembly includes a traction outboard plate fixed to the outside of the rear decompression hood, one end of the traction outboard plate is fixed with a spring connecting rod, one end of the spring connecting rod is fixed with a connecting traction plate, and one end of the connecting traction plate is fixed to the surface of the front boost air collection hood.

[0011] Preferably, the raised connection assembly includes a raised connection platform fixed to the inner wall of the rear decompression cover, and the surface of the raised connection platform is fixedly connected to the mesh traction wire.

[0012] Preferably, the rib corner guide plate is located at the front end of the fin heat sink, and the convex rib end of the rib corner guide plate is arranged away from the fin heat sink.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets a mesh traction wire. The front-mounted supercharged air collecting hood increases the air collection volume through the large front-end diameter, thereby increasing the gas flow rate inside the cross-flow connecting tube. The speed-following paddle can change the rotation angle of the front-mounted supercharged air collecting hood under the influence of vehicle speed, so that the mesh traction wire is in a relaxed state when the car is at low speed. The vibration of the vehicle body drives the mesh traction wire to shake off the debris attached to the surface, thereby improving the heat dissipation stability of the device. When traveling at high speed, the mesh traction wire is in a taut state to reduce shaking, which is convenient for filtering debris. After the air flows into the rear decompression hood, the ventilation volume increases and the air flow rate becomes smaller than the flow rate in the cross-flow connecting tube. After the air flow is guided by the rib angle guide plate, the turbulence is reduced, so that the gas is tilted to blow toward the wing heat sink, avoiding the accumulation of dust and debris in the grooves of the wing heat sink, which affects the heat dissipation stability of the radiator.

[0014] 2. The present invention adopts the arrangement of a spring connecting rod, which can cooperate with the rear pressure-reducing cover and the front pressurized air collecting cover to change the tightening state of the mesh traction wire according to the vehicle speed. It actively disperses attachments at low speeds and actively filters attachments at high speeds to prevent attachments from falling onto the fin heat sink due to the high intake air velocity at high speeds. Attachments that affect the intake are promptly cleared according to the vehicle's travel speed, thereby ensuring the stability of the heat dissipation of the device.

[0015] 3. The present invention cooperates with the rib-angle guide plate and the mesh traction wire to form a barrier in front of the fin heat sink. When flushing the radiator, the damage to the fin heat sink can be effectively reduced, and the fin heat sink can be prevented from being damaged by flushing, thereby reducing the air intake volume to form turbulence, affecting the heat dissipation stability of the device, and causing secondary damage to the fin heat sink due to turbulence.

[0021] Example, see Figures 1 to 7 A high-efficiency composite radiator includes a thin-walled heat dissipation component and an overflow connection cover 1. Furthermore, the thin-walled heat dissipation component includes a heat dissipation grid frame 9, one end of the overflow connection cover 1 is sleeved on the surface of the heat dissipation grid frame 9, a fin heat dissipation fin 10 is fixed inside the grille of the heat dissipation grid frame 9, and a circulation component is provided on one side of the heat dissipation grid frame 9. Furthermore, the circulation component includes a circulation pipe 11 fixed to the side of the heat dissipation grid frame 9, and the circulation pipe 11 is connected to the heat dissipation grid frame 9; A further benefit of adopting the above method is that the circulation pipe 11 is used to form a circulation channel in the heat dissipation grid frame 9. After the hot air in the engine flows into the air intake pipe 12, it can flow out from the air outlet pipe 16 through the heat dissipation grid frame 9 and the circulation pipe 11.

[0022] The heat dissipation grid frame 9 is provided with a fixing assembly. Further, the fixing assembly includes a positioning plate 13 fixed to both sides of the heat dissipation grid frame 9. The inner wall of the positioning plate 13 is plugged with a fixing bolt 14. A further advantage of adopting the above method is that the fixing bolts 14 can fix the heat dissipation grid frame 9 on the vehicle frame through the positioning plate 13 to prevent the heat dissipation grid frame 9 from shaking.

[0023] The liquid inlet of the heat dissipation grid frame 9 is fixed with an air inlet drainage pipe 12, and the liquid outlet of the heat dissipation grid frame 9 is fixed with an air outlet drainage pipe 16; A further advantage of adopting the above method is that the fin heat sink 10 is used to conduct heat out of the heat dissipation grid frame 9 and dissipate heat through the airflow collected by the front boost air collection cover 6.

[0024] The overflow connection cover 1 is connected to the thin-wall heat dissipation component through a limiting component. Furthermore, the limiting component includes a limiting ring 15 fixed to the inner wall of the overflow connection cover 1, and one end of the limiting ring 15 is tightly fitted to the surface of the heat dissipation grid frame 9.

[0025] A further benefit of adopting the above method is that the limiting ring 15 is used to limit the depth of the overflow connection cover 1 inserted into the heat dissipation grid frame 9.

[0026] The overflow connection cover 1 is provided with a leakage hole 2 on the peripheral side, and the inner wall of the overflow connection cover 1 is fixed with a rib angle guide plate 3, which is located at the front end of the wing heat sink 10, and the convex rib end of the rib angle guide plate 3 is set away from the wing heat sink 10, and the rib angle guide plate 3 is set in a triangular prism shape. One end of the overflow connection cover 1 is fixed with a rear pressure reduction cover 4, and one end of the rear pressure reduction cover 4 is fixed with a cross-flow connecting tube 5, and one end of the cross-flow connecting tube 5 is sleeved with a front boost air collection cover 6. The outer side of the cross-flow connecting tube 5 is connected to the front boost air collection cover 6 through a traction assembly. Further, the traction assembly includes a traction outer plate 17 fixed to the outer side of the rear pressure reduction cover 4, and a spring connecting rod 18 is fixed to one end of the traction outer plate 17. A connecting traction plate 19 is fixed to one end of the spring connecting rod 18, and one end of the connecting traction plate 19 is fixed to the surface of the front boost air collection cover 6.

[0027] The further advantage of adopting the above method is that after the gas is collected into the front-stage boost air collecting hood 6, the front-stage boost air collecting hood 6 can be rotated according to the air flow rate by the speed-following blade 7 to change the tightness of the mesh traction wire 8. The spring connecting rod 18 plays the role of cooperating with the front-stage boost air collecting hood 6 to adapt to the vehicle speed. The spring connecting rod 18 adapts the rotation angle of the front-stage boost air collecting hood 6 to the vehicle speed through its own elasticity. The rib angle guide plate 3 is a triangular prism. After the gas flows out of the rear-stage decompression hood 4, it passes through the raised ribs at the front end of the rib angle guide plate 3, which can correct the turbulent airflow flowing through the front-stage boost air collecting hood 6 and the cross-flow connecting tube 5, and at the same time can make The gas is blown at a certain angle to the grooves where the wing heat sink 10 and the heat dissipation grid frame 9 are connected to clean up debris and avoid the accumulation of debris and dust in the grooves. Due to the dense mesh structure composed of the woven mesh traction wire 8, the gas forms turbulence after passing through, and blows directly to the wing heat sink 10, causing damage to the wing heat sink 10, affecting the heat dissipation stability. The front-mounted boost air hood 6 changes the airflow velocity by increasing the amount of airflow entering, prompting the heat dissipation grid frame 9 to conduct to the overflow connection hood 1, the rear pressure reducing hood 4, the cross-flow connection tube 5 and the front-mounted boost air hood 6 to accelerate the blowing of heat when the airflow increases, thereby improving the stability of the heat dissipation of the device. At the same time, the discharge of gas from the escape vent 2 can also accelerate the cooling of the heat dissipation device.

[0028] A raised connection assembly is provided inside the rear decompression hood 4. Further, the raised connection assembly includes a raised connection platform 20 fixed to the inner wall of the rear decompression hood 4. The surface of the raised connection platform 20 is fixedly connected to the mesh traction wire 8.

[0029] A further advantage of adopting the above method is that the raised connecting platform 20 has the effect of connecting the mesh traction wires 8 and can cooperate with the speed-following paddles 7 to form a multi-layer cross-arranged mesh structure of the mesh traction wires 8.

[0030] A speed-following paddle 7 is fixed to the inner wall of the front-mounted boost air collection hood 6, and a mesh traction wire 8 is fixed to one end of the speed-following paddle 7. One end of the mesh traction wire 8 is connected to the raised connecting component, and the mesh traction wire 8 can form a multi-layer mesh structure through the speed-following paddle 7 and the raised connecting component.

[0031] When the present invention is in use, the size of the airflow blowing toward the heat dissipation grid frame 9 varies with the speed of the vehicle. Therefore, during the vehicle's driving, the gas entering the front-stage supercharged air collecting cover 6 can drive the front-stage supercharged air collecting cover 6 to rotate by blowing the speed-following paddles 7. When the front-stage supercharged air collecting cover 6 rotates, the presence of the spring connecting rod 18 can constrain the rotation angle of the front-stage supercharged air collecting cover 6. That is, when the vehicle speed is fast, the rotation angle of the front-stage supercharged air collecting cover 6 is large, and conversely, when the vehicle speed is slow, the rotation angle is small. When the front-mounted pressurized air collecting hood 6 rotates, the tightness of the mesh traction wire 8 can be changed, that is, it is loose at low speed and tight at high speed. In the loose state, the mesh traction wire 8 has a large vibration amplitude, and the mesh traction wires 8 will rub against each other when shaking, so that the insect bodies and other debris attached to the mesh traction wire 8 can be shaken off to complete self-cleaning. In the tight state, the vibration amplitude of the mesh traction wire 8 is small, and it is mainly affected by the airflow. The multi-layer structure formed by the mesh traction wire 8 in the tight state is dense and stable, and has strong filtering performance, so the insect body and other debris are not easy to fall off; The gas flows in from the front-stage boost air collecting hood 6, passes through the woven mesh traction wire 8, and passes through the large front end of the front-stage boost air collecting hood 6, resulting in an increase in the air intake volume. Therefore, the flow rate increases when passing through the cross-flow connecting tube 5. After flowing out from the rear-stage decompression hood 4, the gas flux becomes larger, so the flow rate decreases. After the gas blows to the rib angle guide plate 3, the rib angle guide plate 3 combs the turbulence and blows it to the wing body heat sink 10. Because the setting of the front-stage boost air collecting hood 6 increases the air intake volume, the air flow increases relatively when the gas blows to the wing body heat sink 10, which can improve the heat dissipation efficiency. The gas that cannot be discharged in time can flow out through the escape vent 2 on the side of the overflow connecting hood 1 to prevent gas accumulation there. The increase in air pressure affects the gas flow rate and affects the heat dissipation stability of the device.

[0032] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
