Description

Technical Field

[0001] This utility model relates to the field of finned tube radiators, specifically a finned tube radiator for hydrogen fuel cell vehicles. Background Technology

[0002] Finned tube radiators are devices that improve heat exchange efficiency by increasing the heat dissipation surface area. They are widely used in heating, cooling, and industrial equipment heat dissipation. Finned tube radiators for hydrogen fuel cell vehicles are thermal management components specifically designed for hydrogen fuel cell vehicles. Their core function is to efficiently dissipate excess heat in the thermal management system, ensuring that key components such as fuel cells, motors, and batteries operate at suitable temperatures.

[0003] In existing technologies, during the operation of existing hydrogen fuel cell vehicles, the internal coolant needs to dissipate heat through finned tube radiators after heat exchange to prevent the engine from overheating. However, over long-term use, dust will adhere to the surface of the base tubes. Existing finned tube radiators are not easy to clean the dust on the base tubes, which reduces the heat dissipation efficiency. At the same time, due to the limited space in hydrogen fuel cell vehicles, existing finned tube radiators are not easy to extend the flow distance of the coolant in a small space, which further reduces the heat dissipation efficiency. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of inconvenience in cleaning dust from the base tube and inconvenience in extending the flow distance of coolant in a small space, this utility model proposes a finned tube radiator for hydrogen fuel cell vehicles.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A finned tube radiator for hydrogen energy vehicles according to this utility model includes a frame plate, connecting blocks are fixedly connected to both sides of the frame plate, a cleaning component is rotatably connected to the top of the connecting blocks, a connecting pipe is connected through the surface of the frame plate, and an A connecting flange is fixedly connected to one end of the connecting pipe. The surface of the A connecting flange is connected to a base tube component in a ring array thread. The cleaning assembly includes a gear rotatably connected to the top of a connecting block, a rack belt meshing with the surface of the gear, a transmission rod fixedly connected to the top of the gear, a splined connection at the top of the transmission rod to the output end of a servo motor, a threaded rod fixedly connected to the bottom of the gear, a threaded cylinder threadedly connected to the surface of the threaded rod, a connecting plate fixedly connected to one side of the threaded cylinder, and bristles fixedly connected to one side of the connecting plate. The base pipe assembly includes connecting bolts arranged in a ring array and threadedly connected to the surface of the A connecting flange. The surface of the connecting bolts is threadedly connected to the B connecting flange. One end of the B connecting flange overlaps the A connecting flange, and the other end of the B connecting flange is fixedly connected to a spiral base pipe.

[0006] Preferably, a support block is fixedly connected to the top of the frame plate, and a top plate is fixedly connected to the top of the support block.

[0007] Preferably, a motor box is fixedly connected to the top of the top plate, and a servo motor is fixedly connected to the inner surface of the motor box.

[0008] Preferably, a gear is rotatably connected to the bottom edge of the top plate, and the top plate is connected through the surface of the transmission rod.

[0009] Preferably, a limiting plate is fixedly connected to the edges on both sides of the frame plate, and a toothed strip is overlapped on the top of the limiting plate.

[0010] Preferably, a support plate is fixedly connected to the bottom of the frame plate, and a threaded rod is rotatably connected to the top of the support plate.

[0011] The advantages of this utility model are: 1. This utility model, through the structural design of the cleaning component, allows the servo motor to be connected to the power supply during the use of the finned heat sink. This causes the transmission rod to drive one of the gears to rotate, and through the rack and pinion belt drive, all gears rotate synchronously, thereby causing the threaded rod to rotate synchronously. The thread of the threaded rod pushes the threaded cylinder to rise and fall, and drives the connecting plate to move. Then, the brush bristles on the side of the connecting plate clean the surface of the spiral base tube, enabling the finned tube heat sink to clean the dust on the base tube and improve the heat dissipation efficiency. 2. Through the structural design of the base tube assembly, before using the finned radiator, the A connecting flange and the B connecting flange are connected and then the connecting bolts are screwed in to complete the connection of the spiral base tube. When the coolant flows into the spiral base tube after heat exchange, the spiral direction of the spiral base tube extends the flow time of the coolant in the base tube, thereby enabling the finned tube radiator to extend the flow distance of the coolant in a smaller space and further improve the heat dissipation efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1-4 As shown, a finned tube radiator for hydrogen fuel cell vehicles includes a frame plate 1, connecting blocks 2 are fixedly connected to both sides of the frame plate 1, a cleaning component 3 is rotatably connected to the top of the connecting blocks 2, a connecting pipe 4 is connected through the surface of the frame plate 1, an A connecting flange 5 is fixedly connected to one end of the connecting pipe 4, and a base tube component 6 is connected to the surface of the A connecting flange 5 in a ring array threaded manner. The cleaning component 3 includes a gear 301 rotatably connected to the top of the connecting block 2. A rack belt 302 is meshed with the surface of the gear 301. A transmission rod 303 is fixedly connected to the top of the gear 301. The top of the transmission rod 303 is splinedly connected to the output end of the servo motor 304. A threaded rod 305 is fixedly connected to the bottom of the gear 301. A threaded cylinder 306 is threadedly connected to the surface of the threaded rod 305. A connecting plate 307 is fixedly connected to one side of the threaded cylinder 306. Brush bristles 308 are fixedly connected to one side of the connecting plate 307. During operation, the servo motor 304 is connected to the power supply and powered on, causing the transmission rod 303 to drive one of the gears 301 to rotate. This is then transmitted through the rack and pinion belt 302, causing all gears 301 to rotate synchronously. This, in turn, causes the threaded rod 305 to rotate synchronously. The thread of the threaded rod 305 pushes the threaded cylinder 306 up and down, moving the connecting plate 307. The brush bristles 308 on the side of the connecting plate 307 clean the surface of the spiral base tube 603, cleaning the dust on the base tube and improving heat dissipation efficiency. The base tube assembly 6 allows the A connecting flange 5 to be connected to the B connecting flange 602 before using the finned heatsink, and then the connecting bolts 601 are screwed in to complete the connection of the spiral base tube 603. When the coolant flows into the spiral base tube 603 after heat exchange, the spiral direction of the spiral base tube 603 extends the flow time of the coolant within the base tube, allowing the finned heatsink to extend the coolant flow distance in a smaller space, further improving heat dissipation efficiency.

[0017] Furthermore, a support block 7 is fixedly connected to the top of the frame plate 1, and a top plate 8 is fixedly connected to the top of the support block 7; During operation, the top plate 8 can be supported on the gear 301 by the support block 7. The top plate 8 not only prevents dust from falling on the gear 301 and rack belt 302, but also provides a support surface for the motor box 9.

[0018] Furthermore, a motor box 9 is fixedly connected to the top of the top plate 8, and a servo motor 304 is fixedly connected to the inner surface of the motor box 9. During operation, the motor box 9 can protect the servo motor 304 and fix the servo motor 304 in a vertical position.

[0019] Furthermore, a gear 301 is rotatably connected to the bottom edge of the top plate 8, and the top plate 8 is connected through the surface of the transmission rod 303; During operation, the rotational connection between the top plate 8 and the gear 301 further improves the stability of the gear 301's rotation.

[0020] Furthermore, a limiting plate 10 is fixedly connected to the edges on both sides of the frame plate 1, and a toothed strip 302 is overlapped on the top of the limiting plate 10. During operation, the limiting plate 10 provides support for the bottom of the rack belt 302, preventing the rack belt 302 from falling off due to gravity during operation.

[0021] Furthermore, a support plate 11 is fixedly connected to the bottom of the frame plate 1, and a threaded rod 305 is rotatably connected to the top of the support plate 11. During operation, the entire finned tube radiator is fixed by setting up the support plate 11 and fixing the support plate 11.

[0022] Working principle: When using the finned heat sink, the servo motor 304 is connected to the power supply and powered on, causing the transmission rod 303 to drive one of the gears 301 to rotate. Through the rack and pinion belt 302, all gears 301 rotate synchronously, thereby causing the threaded rod 305 to rotate synchronously. The thread of the threaded rod 305 pushes the threaded cylinder 306 to rise and fall, and drives the connecting plate 307 to move. Then, the brush bristles 308 on the side of the connecting plate 307 clean the surface of the spiral base tube 603. Before using the finned heat sink, the A connecting flange 5 and the B connecting flange 602 are connected and the connecting bolts 601 are screwed in to complete the connection of the spiral base tube 603. When the coolant flows into the spiral base tube 603 after heat exchange, the spiral direction of the spiral base tube 603 prolongs the flow time of the coolant in the base tube, thereby improving the cooling efficiency of the coolant.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
