[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In order to solve existing technical problems such as Figure 1-Figure 7 As shown, the following preferred technical solutions are provided:

[0029] A dual-fan cooperative air-cooled radiator, comprising an air-cooled radiator outer frame mechanism 1, one side of the air-cooled radiator outer frame mechanism 1 is screwed with an air-cooled drive mechanism 2, the upper end of the air-cooled radiator outer frame mechanism 1 is inserted with a marine diesel engine fixing mechanism 4, one side of the air-cooled radiator outer frame mechanism 1 is connected with a combined heat dissipation mechanism 3, the air-cooled radiator outer frame mechanism 1 comprises a frame member 11, the lower end of the frame member 11 is fixedly provided with a bottom plate frame 12, one side of the frame member 11 is fixedly provided with an air outlet frame 14, the air-cooled drive mechanism 2 is screwed with an air-cooled drive mechanism 2, the upper end of the air-cooled radiator outer frame mechanism 1 is inserted with a marine diesel engine fixing mechanism 4, one side of the air-cooled radiator outer frame mechanism 1 is connected with a combined heat dissipation mechanism 3, the air-cooled radiator outer frame mechanism 1 comprises a frame member 11, the lower end of the frame member 11 is fixedly provided with a bottom plate frame 12, and one side of the frame member 11 is fixedly provided with an air outlet frame 14. The driving mechanism 2 includes a pump frame 21 connected to one side of the frame member 11, a side net 121 is provided at the side end of the bottom plate frame 12, a bottom groove 122 is provided at the upper end of one side of the bottom plate frame 12, the pump frame 21 is connected to the bottom groove 122, and the marine diesel engine fixing mechanism 4 is arranged between the pump frame 21 and the combined heat dissipation mechanism 3. The combined heat dissipation mechanism 3 includes a built-in fan 31 side by side with the pump frame 21, and a heat dissipation fin 32 is connected to one side of the built-in fan 31, and a plurality of groups of water-cooling tubes 33 are arranged side by side in the heat dissipation fin 32.

[0030] The side nets 121 are arranged on both sides for preliminary filtering of air, and the side nets 121 are arranged at the lower end. Because the cold air sinks, the air-cooling radiator can absorb the cold air as much as possible to achieve cooling and heat dissipation under the drive of the air-cooling driving mechanism 2. The diesel engine is fixed inside the marine diesel engine fixing mechanism 4. The air-cooling driving mechanism 2 and the combined heat dissipation mechanism 3 are arranged on both sides of the diesel engine to achieve targeted heat dissipation of the marine diesel engine. The built-in fan 31 rotates under the wind drive of the air-cooling driving mechanism 2 to complete heat dissipation for the heat dissipation fins 32. The water-cooling pipe 33 is externally connected to a water pump to realize cooling water circulation. This air-cooling radiator provides a fixed position for the diesel engine and adopts an external single motor to achieve single drive, which reduces the heat source while fully ensuring the heat dissipation effect. The correspondence between the bottom plate frame 12 and the air outlet frame 14 adapts to the normal law that cold air sinks and hot air rises, thereby achieving efficient heat dissipation.

[0031] The bottom plate frame 12 is fixedly arranged at the lower end of the frame member 11. The fixing direction of the side nets 121 on both sides of the bottom plate frame 12 is perpendicular to the fixing direction of the air outlet frame 14 on one side of the frame member 11. The opening of the air outlet frame 14 is obliquely opened upward. The air inlet and air outlet ranges of the side nets 121 and the air outlet frame 14 do not overlap, which can effectively prevent hot air from continuously entering. The oblique upward opening of the air outlet frame 14 allows the air to be discharged upward.

[0032] The air-cooled radiator outer frame mechanism 1 further includes a top plate 13 fixedly arranged at the upper end of the frame member 11 . The top plate 13 is arranged at the upper end to provide a connection foundation for the marine diesel engine fixing mechanism 4 .

[0033] The lower end of the pump frame 21 is connected to an air inlet 211, and one side of the pump frame 21 is connected to a drive motor 22. The air inlet 211 and the bottom groove 122 are matched and connected to each other. The pump frame 21 is connected to one side of the frame member 11 to achieve air-cooled drive.

[0034] The output end of the pump frame 21 is connected to the pump blade 23. The pump frame 21 is a hollow structure. The pump frame 21 drives the pump blade 23 to rotate to drive the air-cooled air. The pump frame 21 is hollow to align with the diesel engine and the combined heat dissipation mechanism 3 fixed side by side.

[0035] The built-in fan 31 is a passive fan. The blades built into the built-in fan 31 rotate naturally under the drive of the air flow of the air-cooling drive mechanism 2. It has no active power, but can disturb the surrounding air flow so that the hot air is in full contact with the heat dissipation fins 32.

[0036] The heat dissipation fins 32 are provided with multiple groups connected in parallel. The heat dissipation fins 32 are arranged side by side with the built-in fan 31. The airflow driven by the built-in fan 31 can blow vertically and evenly through the heat dissipation fins 32 arranged in parallel, reducing the airflow circumference or dispersion loss. The gaps between the heat dissipation fins 32 are fully filled with airflow, and each heat dissipation fin 32 can directly contact the cold air, accelerating the transfer of heat from the fins to the air. At the same time, the parallel connected fins are arranged neatly, the airflow path is smooth when passing through, and the wind resistance is small.

[0037] Four groups of water-cooling pipes 33 are arranged side by side. A support member 34 is provided at the lower end of the water-cooling pipe 33. The support member 34 is connected to the bottom of the frame member 11. The support member 34 is used to fix the water-cooling pipe 33. The four groups of water-cooling pipes 33 are arranged side by side and are externally connected to the same water pump and water inlet main pipe. The water-cooling pipes 33 flow through the heat dissipation area in parallel. The water flow velocity and temperature of each water pipe have very small differences, and can evenly cover the heat dissipation surface.

[0038] The marine diesel engine fixing mechanism 4 includes a square frame 41 inserted into the top plate 13. A cover plate 42 is fixedly provided on the upper end of the square frame 41. The square frame 41 is used to fix the diesel engine. The cover plate 42 is fitted with the top plate 13 to achieve sealing.

[0039] The cover plate 42 is provided with a diesel groove 421 aligned with the injection port of the diesel engine, and an exhaust groove 422 aligned with the exhaust gas discharge of the diesel engine. The diesel groove 421 and the exhaust groove 422 reserve external space for the diesel engine.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
