[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] Embodiment 1:

[0036] Refer to Figures 1-9, a self-cleaning fin radiator, including an outer cover 1, with slots 2 provided on both sides of the outer cover 1, which are the air inlet and the air outlet respectively. It further includes: an inner frame 3, fixedly connected inside the outer cover 1. Among them, a through slot 4 aligned with the slot 2 is provided on the side wall of the inner frame 3, and a rectangular slot 5 communicating with the through slot 4 is provided on the side wall of the inner frame 3; a fan 6 fixedly installed in the through slot 4, and the fan 6 is used to generate an air flow. Among them, multiple groups of inclined heat pipe assemblies are installed inside the outer cover 1, with an inclination angle of 45°, and the number of heat pipe assemblies is 4 to 16 groups. The preferred number in this application is 7 groups, and the heat pipe assemblies cross the rectangular slot 5, and the exhaust end of the fan 6 faces the heat pipe assemblies; a belt 7 sleeved on the outer wall of the inner frame 3. Among them, the belt 7 simultaneously blocks the through slots 4 and the rectangular slot 5 on both sides. A strip-shaped filter screen 8 for filtering dust is installed in a strip-shaped slot 9 on the outer wall of the belt 7, and a driving part for driving the belt 7 to slide along the inner frame 3 is provided on the inner frame 3.

[0037] Specifically, in use, the heat pipe assembly is used to transfer the heat-dissipating liquid. During the heat dissipation of the radiator, the fan 6 will suck air from the slot 2 on one side of the outer cover 1 and discharge it from the slot 2 on the other side of the outer cover 1. When the air flows through the heat pipe assembly, the efficient heat dissipation work of the heat pipe assembly will be completed. The belt 7 at the port of the slot 2 will filter out most of the dust in the air through the strip-shaped filter screen 8, so as to reduce the influence of dust on the heat pipe assembly, ensure the heat dissipation efficiency of the radiator, and can reduce the difficulty of cleaning dust from the radiator. The driving part will continuously convey the belt 7. When the belt 7 drives the strip-shaped filter screen 8 to move to the exhaust end of the fan 6, the air discharged from the slot 2 will blow back the strip-shaped filter screen 8, so that the dust filtered on the outer wall of the strip-shaped filter screen 8 can be blown off, and the automatic cleaning work of the strip-shaped filter screen 8 can be automatically realized, which is more convenient to use and maintains the filtering efficiency of the strip-shaped filter screen 8, indirectly improving the heat dissipation efficiency of the radiator.

[0038] Embodiment Two:

[0039] Refer to Figures 1-2 And Figures 4-6 , which is basically the same as Embodiment One. Furthermore, the specific implementation scheme of the heat pipe assembly is specifically disclosed.

[0040] The heat pipe assembly includes a U-shaped pipe 15 fixedly connected to both sides of the outer cover 1 and two connecting pipes 14. Rotating pipes 16 are rotatably connected between the two connecting pipes 14 and the two ends of the U-shaped pipe 15. Among them, the U-shaped pipe 15, the two connecting pipes 14, and the two rotating pipes 16 form a single-channel pipeline. The rotating pipe 16 passes through the rectangular groove 5. A plurality of annular fins 17 arranged at equal intervals are fixedly connected to the outer wall of the rotating pipe 16. The number of annular fins 17 is 12 - 30, and the preferred number in this application is 18. A driving source for driving the rotating pipe 16 to rotate is provided on the outer wall of the outer cover 1. The driving source includes a motor 20 fixedly installed on the outer wall of the outer cover 1. A driving gear 19 is fixedly installed on the output shaft of the motor 20. Among them, a transmission gear 18 is fixedly installed at the shaft end of each rotating pipe 16, and two adjacent transmission gears 18 are meshed and connected. The driving gear 19 is meshed and connected with one of the transmission gears 18.

[0041] Specifically, during use, the warm liquid is introduced into the rotating pipe 16 through one of the connecting pipes 14. After passing through the two rotating pipes 16 and one U-shaped pipe 15, the warm liquid is discharged from the other connecting pipe 14. When the liquid passes through the rotating pipe 16, heat dissipation can be completed through the annular fins 17. During heat dissipation, the motor 20 drives one of the transmission gears 18 to rotate through the driving gear 19. Since two adjacent transmission gears 18 are meshed with each other, all the transmission gears 18 will rotate synchronously and drive a plurality of rotating pipes 16 to rotate synchronously. The rotating pipes 16 will drive the annular fins 17 on the outer wall to rotate simultaneously. The rotating rotating pipes 16 and annular fins 17 can be in more comprehensive contact with the air, so that it can have a more efficient heat dissipation efficiency, and can also reduce the dust staying on the rotating pipes 16 and annular fins 17. At the same time, the liquid inside will also rotate and complete the transportation in the rotating pipe 16 under the rotation of the rotating pipe 16, enabling the liquid to transfer heat to the rotating pipe 16 more efficiently, indirectly improving the heat dissipation efficiency of the radiator. At the same time, scale is not easily generated on the inner wall of the rotating pipe 16. When large pieces of scale appear, they are also easy to fall off automatically.

[0042] The above-mentioned rotating pipe 16 and the annular fins 17 are integrally formed, and the materials of the rotating pipe 16 and the annular fins 17 are copper, which can effectively ensure the heat dissipation efficiency of the rotating pipe 16 and the annular fins 17.

[0043] Embodiment 3:

[0044] Referring to Figure 2 、 Figure 5 and Figure 6 , it is basically the same as Embodiment 2. Further, the specific implementation scheme of the driving part is specifically disclosed.

[0045] The driving part includes a rotating groove 21 arranged on the outer wall of the inner frame 3, and a rotating rod 22 is rotatably installed in the rotating groove 21, wherein a pulley 23 pressed against the inner wall of the belt 7 is fixedly installed on the outer wall of the rotating rod 22, and at least two groups of pulleys 23 are provided. The rotating rod 22 is connected to one of the rotating tubes 16 through a chain drive 24, and the chain drive 24 is mainly composed of two sprockets and a chain.

[0046] Specifically, when the rotating tube 16 rotates, the rotating tube 16 will drive the rotating rod 22 to rotate through the chain drive 24, the rotating rod 22 will drive the pulley 23 to rotate, and the pulley 23 will drive the belt 7 to continuously transport. When the belt 7 drives the strip filter 8 to move to the exhaust end of the fan 6, the air discharged from the slot 2 will back-blow the strip filter 8, so that the dust filtered by the outer wall of the strip filter 8 can be blown off, and the automatic cleaning work of the strip filter 8 can be automatically realized, which is more convenient to use and maintains the filtering efficiency of the strip filter 8, thereby indirectly improving the heat dissipation efficiency of the radiator.

[0047] Embodiment 4:

[0048] Reference Figure 4 and Figure 7 , which is basically the same as the third embodiment, and further, a specific implementation plan for cleaning the strip filter 8 is specifically added.

[0049] A cross beam 10 is fixedly connected in the above-mentioned strip groove 9, and a slide rod 11 is slidably inserted on the cross beam 10. The strip filter 8 is fixedly connected to one end of the slide rod 11, wherein the other end of the slide rod 11 is fixedly connected to a limit plate 12, and the limit plate 12 and the cross beam 10 are elastically connected by a spring 13. When the fan 6 blows toward the inner wall of the strip filter 8, the strip filter 8 slides in the direction away from the strip groove 9.

[0050] Specifically, when the strip filter 8 is located on the exhaust side of the fan 6, the airflow will cause the strip filter 8 to slide in the direction away from the strip groove 9, and the opening of the strip groove 9 will no longer be blocked by the strip filter 8, so that the dust falling from the rotating tube 16 and the annular fin 17 can be discharged through the strip groove 9, preventing dust from accumulating on the inner wall of the strip filter 8, thereby ensuring the filtering efficiency of the strip filter 8. Since the plurality of rotating tubes 16 are linearly and evenly spaced, when the strip filter 8 is aligned with the rotating tube 16, the rotating tube 16 will block the strip filter 8. , the strip filter 8 will be subjected to a smaller blowing. When the strip filter 8 is toward the gaps between the multiple rotating tubes 16, the airflow received by the strip filter 8 will increase. Therefore, when the strip filter 8 passes through the rotating tubes 16 in sequence, the strip filter 8 will be subjected to the blowing of fluctuating winds. When the blowing is strong, the strip filter 8 is completely separated from the strip groove 9. When the blowing is weak, the spring 13 will drive the strip filter 8 to move in the opposite direction and reset through the sliding rod 11. Therefore, the blowing of fluctuating winds will cause the strip filter 8 to shake back and forth, thereby significantly improving the cleaning effect of the strip filter 8.

[0051] Example 5:

[0052] Refer to Figure 3 、 Figure 5 、 Figure 8 and Figure 9 , which is basically the same as Example 4. Furthermore, a specific implementation scheme for actively cleaning the rotating pipe 16 and the annular fins 17 is specifically added.

[0053] A strip-shaped rod 33 is installed in the through groove 4. A plurality of groups of brushes 25 are fixedly arranged on the outer wall of the strip-shaped rod 33. The ends of the plurality of groups of brushes 25 are respectively attached to a plurality of annular fins 17, and the end shape of each group of brushes 25 is C-shaped.

[0054] Specifically, during the rotation of the rotating pipe 16 and the annular fins 17, the brush 25 can sweep away the dust on the rotating pipe 16 and the annular fins 17, so that dust is not easily accumulated on the outer walls of the rotating pipe 16 and the annular fins 17, ensuring the heat dissipation efficiency of the rotating pipe 16 and the annular fins 17.

[0055] A fixing plate 26 is fixedly connected to the inner wall of the through groove 4. A reciprocating part for driving the brush 25 to approach and move away from the annular fins 17 intermittently is arranged on the fixing plate 26. The reciprocating part includes a reciprocating plate 27 slidably connected to the inner wall of the through groove 4. An elastic member 28 is installed between the reciprocating plate 27 and the fixing plate 26. The strip-shaped rod 33 is fixedly connected to the reciprocating plate 27. Among them, a long shaft 29 is rotatably connected to the inner wall of the through groove 4. A cam 30 attached to the reciprocating plate 27 is fixedly installed on the outer wall of the long shaft 29. A driven gear 31 meshed with one of the transmission gears 18 is fixedly connected to the long shaft 29.

[0056] Specifically, the rotating transmission gear 18 will drive the long shaft 29 to rotate through the driven gear 31. The long shaft 29 will drive the cam 30 to rotate. When the convex part of the cam 30 faces the reciprocating plate 27, the reciprocating plate 27 will move towards the fixing plate 26 and compress the elastic member 28. When the convex part of the cam 30 does not face the reciprocating plate 27, the elastic force of the elastic member 28 will drive the reciprocating plate 27 to move reversely and reset. Therefore, the continuously rotating cam 30 will drive the reciprocating plate 27 to reciprocate. The reciprocating plate 27 will drive the strip-shaped rod 33 to reciprocate. The strip-shaped rod 33 will drive the brush 25 to approach and move away from the rotating pipe 16 intermittently, thereby significantly improving the effect of the brush 25 in cleaning the rotating pipe 16 and the annular fins 17.

[0057] The elastic member 28 is an elastic airbag. A cavity is provided in the strip-shaped rod 33 and is communicated with the elastic member 28. An air suction pipe 32 communicated with the elastic member 28 is fixedly connected to the elastic member 28. Among them, one-way valves are fixedly installed in both the air suction pipe 32 and the strip-shaped rod 33. Each brush 25 is a thin tube and is communicated with the cavity of the strip-shaped rod 33.

[0058] Specifically, when the elastic member 28 is squeezed, the elastic member 28 will blow air toward the brush 25 through the strip rod 33, and the brush 25 will blow air toward the rotating tube 16 and the annular fin 17 through the port, thereby further improving the cleaning effect and also improving the heat dissipation efficiency of the rotating tube 16 and the annular fin 17. When the elastic member 28 is elastically reset, air will be sucked in through the intake pipe 32.

[0059] When the radiator is in use, the warm liquid is passed through one of the connecting tubes 14 into the rotating tube 16. After passing through the two rotating tubes 16 and a U-shaped tube 15, the warm liquid is discharged from the other connecting tube 14. After the liquid passes through the rotating tube 16, it can complete the heat dissipation work through the completed annular fins 17. During the heat dissipation period, the fan 6 causes the slots 2 on one side of the outer cover 1 to absorb air, and after the air flows through the rotating tube 16, it is discharged from the slots 2 on the other side of the outer cover 1. After the air flows through the outer wall of the rotating tube 16, the air will take away part of the temperature on the rotating tube 16 and the annular fins 17, and the efficient heat dissipation work of the rotating tube 16 and the annular fins 17 has been completed.

[0060] During the heat dissipation of the radiator, the belt 7 on the slotted port 2 will filter out most of the dust in the air through the strip filter 8 to reduce the impact of dust on the rotating tube 16 and the annular fin 17, ensure the heat dissipation efficiency of the radiator, and reduce the difficulty of cleaning the dust from the radiator. The motor 20 will drive one of the transmission gears 18 to rotate through the driving gear 19. Since the two adjacent transmission gears 18 are meshed with each other, all the transmission gears 18 will rotate synchronously and drive multiple rotating tubes 16 to rotate synchronously. The rotating tube 16 will simultaneously drive the outer wall of the annular fin 17 to rotate synchronously. The shaped fins 17 rotate, and the rotating rotating tube 16 and the annular fins 17 can be in contact with the air more comprehensively, so that they can have a more efficient heat dissipation efficiency, and can also reduce the dust staying on the rotating tube 16 and the annular fins 17. At the same time, the internal liquid will also be transported by rotating in the rotating tube 16 under the rotation of the rotating tube 16, so that the liquid can transfer heat to the rotating tube 16 more efficiently, indirectly improving the heat dissipation efficiency of the radiator. At the same time, the inner wall of the rotating tube 16 is not easy to produce scale, and when large scale appears, it is easy to fall off automatically.

[0061] When the rotating tube 16 rotates, the rotating tube 16 will drive the rotating rod 22 to rotate through the chain drive 24, and the rotating rod 22 will drive the pulley 23 to rotate, and the pulley 23 will drive the belt 7 to continuously transport. When the belt 7 drives the strip filter 8 to move to the exhaust end of the fan 6, the air discharged from the slot 2 will back-blow the strip filter 8, so that the dust filtered by the outer wall of the strip filter 8 can be blown off, and the automatic cleaning work of the strip filter 8 can be automatically realized, which is more convenient to use and maintains the filtering efficiency of the strip filter 8, thereby indirectly improving the heat dissipation efficiency of the radiator.

[0062] When the strip-shaped filter screen 8 is located on the exhaust side of the fan 6, the airflow will cause the strip-shaped filter screen 8 to slide away from the strip-shaped groove 9, and the opening of the strip-shaped groove 9 will no longer be blocked by the strip-shaped filter screen 8. Then, the dust falling from the rotating pipe 16 and the annular fins 17 can be discharged through the strip-shaped groove 9, preventing dust from accumulating on the inner wall of the strip-shaped filter screen 8 and ensuring the filtering efficiency of the strip-shaped filter screen 8. Since the multiple rotating pipes 16 are linearly and equally spaced, when the strip-shaped filter screen 8 is aligned with the rotating pipe 16, the rotating pipe 16 will block the strip-shaped filter screen 8, and the strip-shaped filter screen 8 will receive less blowing air. When the strip-shaped filter screen 8 faces the gaps between the multiple rotating pipes 16, the airflow received by the strip-shaped filter screen 8 will increase. Therefore, when the strip-shaped filter screen 8 passes by the rotating pipe 16 in sequence, the strip-shaped filter screen 8 will be blown by the air flow that varies from large to small. When the blowing air is large, the strip-shaped filter screen 8 completely disengages from the strip-shaped groove 9. When the blowing air is small, the spring 13 will drive the strip-shaped filter screen 8 to move reversely and reset through the sliding rod 11. Therefore, the blowing air that varies from large to small will cause the strip-shaped filter screen 8 to vibrate reciprocally, which can significantly improve the cleaning effect on the strip-shaped filter screen 8.

[0063] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
