Description

Technical Field

[0001] This invention relates to the field of anti-deposition device technology, and in particular to a high-efficiency composite radiator. Background Technology

[0002] The radiator is a very important component in the internal combustion engine cooling system. It is a thin-walled component manufactured using a soft soldering process, and its function is to transfer the engine's heat to the surrounding atmosphere.

[0003] Existing radiators use removable filters at the front of thin-walled components to facilitate cleaning or prevent the accumulation of lint, leaves, and dead insects on the surface of the thin-walled components. However, the dense mesh structure added to the filter can affect the speed at which air enters the thin-walled components, reducing the stability of the radiator's heat dissipation. Furthermore, although the filter facilitates cleaning after lint, leaves, and dead insects accumulate on the filter screen, it still affects the heat dissipation efficiency of the radiator. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art where adding a filter device affects the stability of heat dissipation of the radiator and the heat dissipation stability is still reduced after the filter device is covered with debris. Therefore, this invention proposes a high-efficiency composite radiator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency composite radiator includes a thin-walled heat dissipation component and an overflow connection cover. The overflow connection cover is connected to the thin-walled heat dissipation component via a limiting component. An escaping and venting hole is provided on the periphery of the overflow connection cover. A rib-shaped guide plate is fixed to the inner wall of the overflow connection cover. The rib-shaped guide plate is triangular in shape. A rear pressure-reducing cover is fixed to one end of the overflow connection cover. A crossflow connecting cylinder is fixed to one end of the rear pressure-reducing cover. A front pressure-increasing and gas-collecting cover is sleeved on one end of the crossflow connecting cylinder. The outer side of the crossflow connecting cylinder is connected to the front pressure-increasing and gas-collecting cover via a traction component. A protruding connecting component is provided inside the rear pressure-reducing cover. A speed-following blade is fixed to the inner wall of the front pressure-increasing and gas-collecting cover. A woven traction wire is fixed to one end of the speed-following blade. One end of the woven traction wire is connected to the protruding connecting component, and the woven traction wire can form a multi-layered mesh structure through the speed-following blade and the protruding connecting component.

[0007] Preferably, the thin-walled heat dissipation assembly includes a heat dissipation grid frame, one end of the overflow connection cover is sleeved on the surface of the heat dissipation grid frame, finned heat dissipation fins are fixed inside the grid 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 pipe is fixed to the liquid inlet of the heat dissipation grid frame, and an air outlet pipe is fixed to the liquid outlet of the heat dissipation grid frame.

[0008] 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.

[0009] Preferably, the fixing component includes positioning plates fixed to both sides of the heat dissipation grid frame, and fixing bolts are inserted into the inner wall of the positioning plates.

[0010] Preferably, the limiting component includes a limiting ring fixed to the inner sidewall of the overflow connection cover, and one end of the limiting ring is tightly attached to the surface of the heat dissipation grid frame.

[0011] Preferably, the traction assembly includes a traction outer guide plate fixed to the outside of the rear decompression cover, a spring connecting rod fixed to one end of the traction outer guide plate, a connecting traction plate fixed to one end of the spring connecting rod, and one end of the connecting traction plate fixed to the surface of the front pressurization and air collection cover.

[0012] Preferably, the protruding connecting assembly includes a protruding connecting platform fixed to the inner wall of the rear pressure relief cover, and the surface of the protruding connecting platform is fixedly connected to the woven web traction wire.

[0013] Preferably, the rib guide plate is located at the front end of the fin heat sink, and the convex rib end of the rib guide plate is disposed away from the fin heat sink.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention utilizes a woven mesh traction wire configuration. The front-mounted pressurized air-collecting hood increases air collection volume through its large-diameter front end, thereby increasing the gas velocity inside the crossflow connecting cylinder. The speed-dependent paddle blades can change the rotation angle of the front-mounted pressurized air-collecting hood based on vehicle speed. This allows the woven mesh traction wire to be in a relaxed state at low vehicle speeds, where vehicle vibrations cause the traction wire to shake off surface debris, improving the stability of the device's heat dissipation. At high speeds, the traction wire is taut, reducing vibration and facilitating the filtration of debris. After air flows into the rear pressure-reducing hood, the increased airflow volume reduces the airflow velocity relative to the velocity inside the crossflow connecting cylinder. The airflow is guided by the rib guide plates, reducing turbulence and causing the gas to be blown obliquely towards the finned heat sink, preventing dust and debris from accumulating in the grooves of the finned heat sink and affecting the heat dissipation stability of the radiator.

[0016] 2. The present invention, through the setting of the spring connecting rod, can cooperate with the rear pressure relief cover and the front pressure boosting and air collection cover to change the tension of the woven traction wire according to the vehicle speed. At low speed, it actively disperses the attached objects, and at high speed, it actively filters the attached objects, preventing the high airflow velocity at high speed from causing the attached objects to fall onto the heat sink fins. According to the vehicle's travel speed, the attached objects affecting the air intake are cleaned up in time, ensuring the stability of the device's heat dissipation.

[0017] 3. The present invention uses the combination of rib corner guide plates and woven mesh traction wires to form a blockage in front of the finned heat sink. When rinsing the heat sink, it can effectively reduce the damage to the finned heat sink and avoid the finned heat sink being damaged by rinsing, which would reduce the air intake and cause turbulence, affecting the heat dissipation stability of the device and causing secondary damage to the finned heat sink due to turbulence.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Example, refer to Figures 1 to 7 A high-efficiency composite radiator includes a thin-walled heat dissipation component and an overflow connection cover 1. Further, 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 finned heat dissipation fin 10 is fixed inside the grid of the heat dissipation grid frame 9. A circulation component is provided on one side of the heat dissipation grid frame 9. Further, the circulation component includes a circulation pipe 11 fixed to the side of the heat dissipation grid frame 9. The circulation pipe 11 is connected to the heat dissipation grid frame 9.

[0030] A further advantage of the above is that the circulation pipe 11 is used to form a circulation channel within the heat dissipation grid frame 9. After the hot air in the engine flows into the intake manifold 12, it can flow out from the exhaust manifold 16 through the heat dissipation grid frame 9 and the circulation pipe 11.

[0031] The heat dissipation grid frame 9 is provided with a fixing component. Further, the fixing component includes a positioning plate 13 fixed to both sides of the heat dissipation grid frame 9, and a fixing bolt 14 is inserted into the inner wall of the positioning plate 13.

[0032] A further advantage of the above is that the fixing bolt 14 can fix the heat dissipation mesh frame 9 to the frame through the positioning plate 13, preventing the heat dissipation mesh frame 9 from shaking.

[0033] The liquid inlet of the heat dissipation grid frame 9 is fixed with an air inlet pipe 12, and the liquid outlet of the heat dissipation grid frame 9 is fixed with an air outlet pipe 16.

[0034] A further advantage of the above is that the finned heat sink 10 is used to conduct heat out from the heat dissipation grid frame 9 and dissipate it through the airflow drawn in by the front pressurized air intake shroud 6.

[0035] The overflow connection cover 1 is connected to the thin-walled heat dissipation assembly through a limiting component. Furthermore, the limiting component includes a limiting ring 15 fixed to the inner sidewall of the overflow connection cover 1, and one end of the limiting ring 15 is tightly attached to the surface of the heat dissipation grid frame 9.

[0036] A further advantage of the above 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.

[0037] An overflow connection cover 1 has an escaping hole 2 on its periphery. A rib guide plate 3 is fixed to the inner wall of the overflow connection cover 1. The rib guide plate 3 is located at the front end of the fin heat sink 10, and the convex rib end of the rib guide plate 3 is set away from the fin heat sink 10. The rib guide plate 3 is set in the shape of a triangular prism. A rear pressure relief cover 4 is fixed to one end of the overflow connection cover 1. A crossflow connecting cylinder 5 is fixed to one end of the rear pressure relief cover 4. A front pressure boosting and gas collection cover 6 is sleeved on one end of the crossflow connecting cylinder 5. The outside of the crossflow connecting cylinder 5 is connected to the front pressure boosting and gas collection cover 6 through a traction assembly. Further, the traction assembly includes a traction outer guide plate 17 fixed to the outside of the rear pressure relief cover 4. A spring connecting rod 18 is fixed to one end of the traction outer guide plate 17. A connecting traction plate 19 is fixed to one end of the spring connecting rod 18. One end of the connecting traction plate 19 is fixed to the surface of the front pressure boosting and gas collection cover 6.

[0038] The further advantages of the above are: after the gas is drawn into the front pressurization and gas collection hood 6, the front pressurization and gas collection hood 6 can be rotated according to the airflow speed by the speed-following paddle 7, changing the tension of the woven traction wire 8. The spring connecting rod 18 plays a role in adapting the front pressurization and gas collection hood 6 to the vehicle speed. The spring connecting rod 18 uses its own elasticity to adapt the rotation angle of the front pressurization and gas collection hood 6 to the vehicle speed. The rib corner guide plate 3 is triangular prism-shaped. After the gas flows out from the rear pressure reducing hood 4, it passes through the protruding rib at the front end of the rib corner guide plate 3, which can correct the turbulent airflow flowing through the front pressurization and gas collection hood 6 and the crossflow connecting cylinder 5, and at the same time, it can make... The gas is blown at a certain angle into the grooves at the connection between the finned heat sink 10 and the heat dissipation grid frame 9 to clean away debris and prevent the accumulation of debris and dust in the grooves. Due to the dense mesh structure formed by the woven traction wires 8, the gas forms turbulence after passing through. When it blows directly onto the finned heat sink 10, it causes damage to the finned heat sink 10 and affects the heat dissipation stability. The front pressurized gas collection hood 6 changes the airflow velocity by increasing the airflow intake, which causes the heat dissipation grid frame 9 to conduct heat to the overflow connecting hood 1, the rear pressure reducing hood 4, the crossflow connecting cylinder 5 and the front pressurized gas collection hood 6. When the airflow increases, the heat dissipation volume is accelerated, which improves the heat dissipation stability of the device. At the same time, the gas discharged through the escaping vent 2 can also accelerate the cooling of the heat dissipation device.

[0039] The rear pressure relief cover 4 has a protruding connecting assembly inside. Further, the protruding connecting assembly includes a protruding connecting platform 20 fixed to the inner wall of the rear pressure relief cover 4. The surface of the protruding connecting platform 20 is fixedly connected to the woven traction wire 8.

[0040] The further advantage of the above is that the raised connecting platform 20 serves to connect the weaving traction wire 8 and can cooperate with the speed-following paddle 7 to form a multi-layered cross-laid mesh structure of the weaving traction wire 8.

[0041] The inner wall of the front-mounted pressurized air intake cover 6 is fixed with a speed-following blade 7. One end of the speed-following blade 7 is fixed with a woven traction wire 8. One end of the woven traction wire 8 is connected to the protruding connecting component. The woven traction wire 8 can form a multi-layer mesh structure through the speed-following blade 7 and the protruding connecting component.

[0042] When the car is in use, the airflow blowing towards the heat dissipation mesh frame 9 varies depending on the vehicle speed. Therefore, during the car's operation, the gas entering the front supercharger shroud 6 can drive the front supercharger shroud 6 to rotate by blowing the follower blades 7. When the front supercharger shroud 6 rotates, the presence of the spring connecting rod 18 can constrain the rotation angle of the front supercharger shroud 6. That is, the rotation angle of the front supercharger shroud 6 is large when the vehicle speed is high, and small when the vehicle speed is low.

[0043] When the front-mounted pressurized air intake hood 6 rotates, the tension of the woven mesh traction wire 8 can be changed, i.e., it is relaxed at low speed and tightened at high speed. When it is relaxed, the woven mesh traction wire 8 vibrates a large amplitude and rubs against each other when it shakes. Therefore, the insect bodies and other debris attached to the woven mesh traction wire 8 can be shaken off to complete self-cleaning. When it is tightened, the vibration amplitude of the woven mesh traction wire 8 is smaller and is mainly affected by the airflow. The multi-layer structure formed when the woven mesh traction wire 8 is tightened is dense and stable and has strong filtration. Therefore, insect bodies, dried corpses and other debris are not easy to fall off.

[0044] Gas flows in from the front pressurized gas collection hood 6, passes through the woven traction wire 8, and the front port of the front pressurized gas collection hood 6 is large, resulting in an increased air intake. Therefore, the flow velocity increases when passing through the crossflow connecting cylinder 5. After flowing out from the rear pressure reducing hood 4, the gas flow rate increases, thus the flow velocity decreases. After the gas is blown to the rib corner guide plate 3, the rib corner guide plate 3 combs the turbulent flow and blows it towards the fin heat sink 10. Because the setting of the front pressurized gas collection hood 6 increases the air intake, the airflow increases relatively when the gas blows towards the fin heat sink 10, which can improve the heat dissipation efficiency. Gas that cannot be discharged in time can flow out through the escaping hole 2 on the side of the overflow connecting hood 1 to prevent gas accumulation at this point. Increased gas pressure affects the gas flow velocity and affects the heat dissipation stability of the device.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
