The liquid inlet pipe 3 is provided with two liquid inlets.

[0036] The heat exchanger 1 has several fins 2 fixedly connected at intervals inside. A first heat exchange tube 7 and a second heat exchange tube 8 are fixedly threaded through these fins 2. The middle sections of both the first heat exchange tube 7 and the second heat exchange tube 8 consist of multiple L-shaped structures connected end-to-end. This allows the first and second heat exchange tubes 7 and 8 to pass through the fins 2 multiple times via bends, enabling heat exchange between the fluid flowing within the tubes and the fins 2, thus achieving rapid cooling.

[0037] One end of the first heat exchange tube 7 is fixedly connected to the liquid inlet pipe 3, and one end of the second heat exchange tube 8 is fixedly connected to the liquid inlet pipe 3. The other ends of both the second heat exchange tube 8 and the first heat exchange tube 7 are fixedly connected to the liquid outlet pipe 4. This allows the fluid to enter the heat exchange box 1 through the first heat exchange tube 7 and the second heat exchange tube 8 respectively for cooling, and the cooled fluid is discharged together through the liquid outlet pipe 4.

[0038] A cooling fan (not shown in the figure) is installed below the heat exchange box 1. The cooling fan is an evaporative cooling product and is an existing product. The cooling fan blows air into the heat exchange box 1 to cool the fins 2.

[0039] Two liquid inlet openings on the liquid inlet pipe 3 are fixedly provided with buffer boxes 5, and each buffer box 5 is vertically and slidably provided with a filter plate 6 close to one end of the liquid inlet pipe 3. The filter plate 6 is used for filtering impurities in the fluid, so as to reduce the impurities entering the first heat exchange pipe 7 and the second heat exchange pipe 8 and affecting the heat exchange effect. The side surface of each filter plate 6 is rotatably connected with a scraper 9.

[0040] Each buffer box 5 is provided with a sliding groove, and the filter plate 6 is vertically and slidably arranged in the corresponding sliding groove. The side surface of each filter plate 6 is provided with a mounting groove, and a plurality of filter holes are uniformly arranged on the filter plate 6 at the mounting groove. The filter plate 6 is filtered through the mounting groove, and the filtered impurities are also located in the mounting groove.

[0041] One end of the scraper 9 is rotatably connected to the bottom of the mounting groove, and the end of the scraper 9 rotatably connected with the mounting groove is provided with a rectangular groove. The scraper 9 is rotated to scrape off the impurities on the mounting groove, so as to clean one side of the filter plate 6.

[0042] The bottom of the buffer box 5 is fixedly connected with a support seat 13, and a square rod 24 is movably and penetrates through the support seat 13. The vertical section of the square rod 24 is rectangular, and one end of the square rod 24 is movably and connected in the rectangular groove. One end of the square rod 24 is clamped in the rectangular groove, so as to position the scraper 9 and the filter plate 6 in the buffer box 5, and the square rod 24 can drive the scraper 9 to rotate by rotating.

[0043] The top surface of one end of the square rod 24 close to the scraper 9 is obliquely arranged, and the oblique surface of the square rod 24 gradually inclines upward from one end close to the scraper 9 to the other end.

[0044] The bottom of the buffer box 5 is fixedly connected with a mounting plate 28, and the top of the mounting plate 28 is rotatably connected with a rotating disc 14. The square rod 24 horizontally and penetrates through the rotating disc 14. When the square rod 24 rotates, the rotating disc 14 rotates on the mounting plate 28, so as to increase the stability of the square rod 24.

[0045] One end of the square rod 24 is fixedly connected with a rotating shaft 30, the rotating shaft 30 rotatably penetrates through the end surface of the buffer box 5, and one end of the rotating shaft 30 extending out of the buffer box 5 is fixedly connected with a limiting disc 15.

[0046] The square rod 24 is fixedly sleeved with a limiting plate 23. The square rod 24 is sleeved with a second spring 16 between the limiting plate 23 and the rotating disc 14. One end of the second spring 16 is fixedly connected to one side of the limiting plate 23, and the other end of the second spring 16 is fixedly connected to one side of the rotating disc 14. In the initial state, the second spring 16 pushes the limiting plate 23, so that one end of the square rod 24 is located in the rectangular groove.

[0047] The bottom of the buffer box 5 is detachably provided with a collecting box 26 located at the bottom of one side of the filter plate 6. The impurities scraped off from the filter plate 6 fall into the collecting box 26. The interior of the collecting box 26 is symmetrically and vertically slidably provided with two pressing plates 12 which are slidably fitted at one end close to each other.

[0048] The bottom surface of the buffer box 5 is provided with a discharge port, and the collecting box 26 is bolted at the discharge port. This facilitates the disassembly of the collecting box 26 and the cleaning of the impurities in the collecting box 26.

[0049] The two inner walls of the buffer box 5 are fixedly connected with positioning plates 27, and the bottoms of the two positioning plates 27 are fixedly connected with guide columns 10, and the bottoms of the two guide columns 10 extend into the collecting box 26. The horizontal section of the guide column 10 is rectangular, and the two pressing plates 12 are slidably sleeved on the two guide columns 10. The guide column 10 positions the up-and-down movement of the pressing plate 12.

[0050] The first spring 11 is provided with two, and the two first springs 11 are sleeved on the two guide columns 10. One end of the first spring 11 is fixedly connected to the bottom of the positioning plate 27, and the other end of the first spring 11 is fixedly connected to the top of the pressing plate 12. In the initial state, the first spring 11 pulls the pressing plate 12 upward, so that the pressing plate 12 is away from the collecting box 26, so that the impurities enter the collecting box 26 from below the pressing plate 12.

[0051] The interior of each buffer box 5 is provided with a driving assembly which drives the reciprocating rotation of the scraper 9 and drives the up-and-down movement of the two pressing plates 12 alternately.

[0052] The driving assembly comprises a motor 20 fixedly connected to one side of the buffer box 5. A worm 21 is rotatably connected in the interior of the buffer box 5, one end of the worm 21 rotatably penetrates through the side surface of the buffer box 5 and is fixedly connected to the output end of the motor 20. The motor 20 drives the rotation of the worm 21.

[0053] One end of the support seat 13 is rotatably connected with a worm wheel 22 which is engaged with the worm 21. The square rod 24 slidably penetrates through the worm wheel 22. The worm 21 drives the rotation of the worm wheel 22, and the worm wheel 22 drives the rotation of the square rod 24.

[0054] The interior of the buffer box 5 is symmetrically rotatably connected with two rotating rods 19. The square rod 24 is located between the two rotating rods 19 and is parallel to the rotating rods 19.

[0055] The bottom surface of the buffer box 5 is fixedly connected with a support plate 17 at the end of each rotating rod 19, and the end of the rotating rod 19 is rotatably connected to the corresponding support plate 17.

[0056] The other end of the support base 13 is rotationally connected with a first gear 25, and a square rod 24 is slidably arranged through the first gear 25. The square rod 24 drives the first gear 25 to rotate. The two rotating rods 19 are each fixedly connected with a second gear 18, and the first gear 25 is engaged with the two second gears 18. The first gear 25 drives the two second gears 18 to rotate, and the two second gears 18 rotate in the same direction.

[0057] The two rotating rods 19 are each fixedly connected with a push rod 29 close to one end of the filter plate 6, and the push rod 29 is perpendicular to the rotating rod 19. The push rod 29 corresponds to the pressing plate 12 one by one, and the push rod 29 is in abutting cooperation with the top surface of the pressing plate 12. When the rotating rod 19 drives the push rod 29 to rotate, the push rod 29 pushes the pressing plate 12 downward, so that the pressing plate 12 slides downward.

[0058] Working principle:

[0059] In use, the heat exchange box 1 is installed, and the cold fan is installed below the heat exchange box 1. The air outlet of the cold fan faces the fins 2.

[0060] The filter plate 6 is moved, and the bottom end of the filter plate 6 is inserted into the sliding groove of the buffer box 5, so that the scraper 9 is moved to the inside of the buffer box 5.

[0061] When the bottom end of the filter plate 6 moves to the end of the square rod 24 provided with the inclined surface, the filter plate 6 continues to move downward to press the inclined surface of the square rod 24. The square rod 24 moves away from the filter plate 6, and the square rod 24 slides on the worm gear 22, the first gear 25 and the rotating disc 14. The rotating shaft 30 slides to the outside of the buffer box 5. The square rod 24 drives the limiting plate 23 to move and compresses the second spring 16.

[0062] When the bottom surface of the filter plate 6 slides to the bottom end of the sliding groove, the end of the square rod 24 corresponds to the rectangular groove of the scraper 9. At this time, the second spring 16 pushes the limiting plate 23 to move, so that the end of the square rod 24 provided with the inclined surface moves into the rectangular groove. Thus, the scraper 9 is positioned in the buffer box 5, and the filter plate 6 is positioned in the sliding groove.

[0063] The fluid to be cooled is respectively introduced into the first heat exchange pipe 7 and the second heat exchange pipe 8 through the two buffer boxes 5.

[0064] The fluid in the first heat exchange pipe 7 and the second heat exchange pipe 8 flows in the pipe and exchanges heat with the fins 2, so as to achieve the purpose of rapid cooling. The cold fan is started, and the cold fan blows cold air to the fins 2 to cool the fins 2.

[0065] When the fluid enters the buffer box 5, it passes through the filter plate 6, and the filter plate 6 filters the impurities in the fluid. The impurities are filtered in the mounting groove on one side of the filter plate 6.

[0066] The fluid does not contain large particles, and the particles flow along with the fluid, so the particles do not accumulate on the worm 21, the worm wheel 22, the first gear 25, and the second gear 28, and do not affect the use of the device.

[0067] The motor 20 is started, the output end of the motor 20 rotates in the positive direction, drives the worm 21 to rotate. The worm 21 drives the worm wheel 22 to rotate, and the worm wheel 22 drives the square rod 24 to rotate. The square rod 24 drives the first gear 25 to rotate, and drives the limiting plate 23, the rotating disc 14, and the rotating shaft 30 to rotate, so that the rotating disc 14 rotates at the top end of the mounting plate 28.

[0068] The first gear 25 drives the second gear 18 to rotate, and the two second gears 18 rotate in the same direction. The second gear 18 drives the rotating rod 19 to rotate, so that the two push rods 29 rotate.

[0069] Since the two push rods 29 rotate in the same direction, one of the push rods 29 presses the pressing plate 12 downward, the pressing plate 12 slides on the corresponding guide column 10, and stretches the corresponding first spring 11. The other push rod 29 rotates away from the pressing plate 12.

[0070] The square rod 24 drives the scraper 9 to rotate in the first direction, so that the scraper 9 scrapes the impurities in one half of the installation groove. The pressing plate 12 at the scraped position is not pressed, so the impurities scraped by the scraper 9 fall from the lower side of the pressing plate 12 into the collecting box 26.

[0071] The output end of the motor 20 reverses, and the scraper 9 rotates in the second direction, and the two push rods 29 rotate.

[0072] The scraper 9 scrapes the impurities in the other half of the installation groove, and the pressing plate 12 at the scraped position is not pressed, so the impurities scraped by the scraper 9 fall from the lower side of the pressing plate 12 into the collecting box 26. The other pressing plate 12 is pressed, so that the other pressing plate 12 compacts the impurities in the collecting box 26, and avoids that the impurities are washed upward by the fluid during use.

[0073] During the process that the push rod 29 rotates away from the pressed pressing plate 12, the first spring 11 pulls the pressing plate 12 upward, so that the pressing plate 12 slides upward on the corresponding guide column 10. Until the first spring 11 returns to the initial state, so as to be pressed again.

[0074] When the scraper 9 scrapes the impurities in one half of the installation groove, the scraped impurities fall from the lower side of the corresponding pressing plate 12, and the other pressing plate 12 compacts the impurities in the collecting box 26 downward. Through the positive rotation and the reverse rotation of the motor 20, the scraping and the compacting work are synchronized and do not affect each other.

[0075] After a period of use, the collection box 26 is removed and the impurities are cleaned.

[0076] When it is necessary to remove the filter plate 6, the limit disc 15 is pulled away from the buffer box 5. The limit disc 15 drives the square bar 24 to move, so that one end of the square bar 24 is away from the rectangular slot on the scraper 9. The square bar 24 no longer limits the scraper 9 and the filter plate 6, and the filter plate 6 can be moved upward and out.

[0077] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to part of the technical features, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
