Description

Technical Field

[0001] This invention relates to the field of energy storage box technology, specifically to a split-type spliced ​​large heat dissipation box with integrated passive air duct. Background Technology

[0002] Electrical equipment is installed inside the energy storage box. Among them, the passive air duct equipment box refers to a closed structure that relies on natural convection (chimney effect) or external airflow guidance, rather than internal active fan drive, to achieve heat dissipation. Its core design lies in optimizing the airflow path and increasing the heat dissipation surface area.

[0003] For example, a novel air-cooled radiator splicing air duct structure, with announcement number CN210519331U, belongs to the field of DC de-icing crystal thyristor valve groups in power systems; it includes an air-cooled radiator; a connecting pipe is detachably installed at the exhaust port at the rear of the air-cooled radiator; the other side of the connecting pipe is installed on the main air duct plate; the main air duct plate is a flat plate structure, and a ventilation hole is opened in the middle of the main air duct plate; the inner tube of the connecting pipe is connected to the ventilation hole.

[0004] Passive airflow energy storage enclosures, based on the physical properties of hot air rising and cold air sinking, typically employ a vertical airflow layout. Cold air enters from the bottom or lower side, flows past the heating elements, and hot air exits from the top. They usually require heat sinks to transfer internal heat to the enclosure's outer shell. Due to the passive airflow cooling system, the interior of the energy storage enclosure lacks active airflow scouring, leading to dust accumulation on the heat sinks, necessitating timely cleaning. Furthermore, with the air inlet at the bottom and the outlet at the top, the faster, outward-directed airflow at the outlet reduces dust accumulation. However, the reduced airflow velocity at the inlet, transitioning from kinetic to static flow or passing through filter media, makes it easier for dust to settle and adhere beneath the heat sinks. Existing heat sink cleaning structures are inconvenient for comprehensive cleaning of the heat sinks around the electrical equipment, and the cleaning effect cannot be easily adjusted based on the amount of dust, resulting in generally poor cleaning performance. This negatively impacts the passive cooling efficiency and the heat conduction of the heat sinks.

[0005] Therefore, a modular, large-scale heat dissipation enclosure with integrated passive airflow is proposed to address the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a modular, spliced ​​large heat dissipation box with integrated passive air duct, in order to solve the problems that it is inconvenient to clean the heat sinks around electrical equipment as a whole, and that the cleaning effect is not easy to adjust according to the amount of dust, resulting in a relatively poor cleaning effect.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a split-type splicing large heat dissipation box with integrated passive air duct, comprising two energy storage boxes, electrical equipment and a top cover fixedly installed on the top of the energy storage boxes, wherein a cover is fixedly installed on the top of the top cover; Also includes: The energy storage box has air inlets on the front and sides, and an air outlet on the top of the top cover. An auxiliary air guide assembly is installed inside the energy storage box, and splicing assemblies are installed on the sides of the energy storage box. Heat sinks are fixedly installed on the inner wall of the energy storage box. The auxiliary air guide assembly includes a drive unit and a cleaning unit. The drive unit is located on the top surface of the top cover and is used to drive the horizontal and vertical bars on the top cover to move. The horizontal bars move horizontally and the vertical bars move vertically. The movement of the horizontal and vertical bars is coordinated to drive the cleaning units around the outside of the electrical equipment to work synchronously. The cleaning unit is used to scrape and clean the heat sinks around the outside of the electrical equipment. The scraping force during cleaning can be adjusted to match the amount of dust on the outside of the heat sinks. By using the heat sinks that are evenly distributed around the outside of the electrical equipment, the space inside the energy storage box is divided into multiple small spaces, thereby assisting external gas to enter from the air inlet and then be discharged from the air outlet, and quickly carrying away the internal heat, thus achieving auxiliary passive air duct heat dissipation.

[0008] Both the air inlet and outlet are equipped with filters. Exhaust fans are symmetrically fixedly installed at the bottom of the top cover. An internal plate is fixedly connected to the end of the heat sink away from the electrical equipment. The drive unit includes two mounting boxes fixedly connected to the middle of the top of the top cover. A servo motor is fixedly installed inside the mounting box. A lead screw is fixedly connected to the output end of the servo motor through the mounting box. A threaded sleeve is threaded to the outside of the lead screw. The bottom of the threaded sleeve is fixedly connected to a crossbar.

[0009] By adopting the above technical solution, when cleaning the heat sink on the outside of electrical equipment, the horizontal and vertical bars can be driven to move synchronously, thereby cleaning the heat sink around the device simultaneously. At the same time, the scraper under the heat sink will gradually press against the heat sink, improving the cleaning effect of the dust under the heat sink and making it suitable for cleaning the larger amount of dust attached to the bottom.

[0010] A push rod is fixedly connected to the outer side of the screw sleeve, and a fixed vertical plate is fixedly connected to the top of the top cover. A guide rod is slidably connected horizontally and longitudinally inside the fixed vertical plate. A trapezoidal plate is fixedly connected to the side of the guide rod near the mounting box. The push rod abuts against the inclined surface of the trapezoidal plate. The trapezoidal plate is fixedly connected to the longitudinal bar. A sliding plate is fixedly connected to the end of the guide rod away from the trapezoidal plate. The longitudinal bar is slidably connected to the sliding plate. A spring is sleeved on the outer side of the guide rod. The two ends of the spring are fixedly connected to the fixed vertical plate and the sliding plate, respectively. Both the horizontal bar and the longitudinal bar are slidably connected to the energy storage box.

[0011] By adopting the above technical solution, the servo motor drives the lead screw to rotate, the lead screw rotation will drive the screw sleeve to move horizontally, the push rod pushes the inclined surface of the trapezoidal plate, thereby driving the trapezoidal plate and the guide rod to move, the guide rod drives the slide plate to move, the trapezoidal plate drives the longitudinal bar to move, and the slide plate stretches the spring, so that the horizontal bar and the longitudinal bar move synchronously.

[0012] The cleaning unit includes multiple connecting strips. The horizontal and vertical strips pass through the energy storage box and are fixedly connected to the connecting strips. Four connecting strips are symmetrically arranged and located around the outer perimeter of the electrical equipment. A U-shaped plate is fixedly connected to the bottom of each connecting strip. The number of U-shaped plates is the same as that of the heat sink, and the U-shaped plates are sleeved on the outside of the heat sink. Fixed scrapers are fixedly connected to the upper sides of both inner walls of the U-shaped plates, and sliding rods are slidably connected to the lower sides of both inner walls of the U-shaped plates.

[0013] By adopting the above technical solution, when the connecting strip moves, it will drive the U-shaped plate to move, and the U-shaped plate will then drive the fixed scraper and the adjusting scraper to move. The fixed scraper and the adjusting scraper will scrape away the dust on the outside of the heat sink.

[0014] One end of the slide rod is fixedly connected to an adjusting scraper, and the other end of the slide rod is fixedly connected to a contact plate. A second spring is sleeved on the outside of the slide rod. The two ends of the second spring are fixedly connected to the U-shaped plate and the contact plate, respectively. The contact plate is located on the outside of the U-shaped plate. A guide inclined plate is installed on the side of the contact plate away from the U-shaped plate. The guide inclined plate is fixedly connected to the inner plate, and the inclination directions of two adjacent guide inclined plates are opposite.

[0015] By adopting the above technical solution, the contact plate is guided by the guide plate, which will compress the spring and drive the slide rod to move. The slide rod drives the adjusting scraper to move, and the pressing force of the adjusting scraper against the lower part of the heat sink will gradually increase.

[0016] The splicing assembly includes a mounting plate fixedly connected to the side of the energy storage tank. A screw is rotatably connected inside the mounting plate, and a movable sleeve is threadedly connected to the outside of the screw. A bonding plate is fixedly connected to the outside of the movable sleeve, and the bonding plate is bonded to the energy storage tank.

[0017] By adopting the above technical solution, the bonding plate limits the movement of the sleeve, preventing it from rotating.

[0018] The side of the bonding plate away from the movable sleeve is fixedly connected to a sleeve and a rod. The sleeves on both sides correspond one-to-one with the rods, so that the sleeve on one side can be inserted into the rod on the other side. A locking rod is vertically slidably installed on the outside of the sleeve.

[0019] By adopting the above technical solution, rotating the screws on both sides causes the movable sleeves on both sides to move closer to each other. The movable sleeves drive the bonding plate to move, and the bonding plate then drives the sleeve and the insertion rod to move.

[0020] An end block is fixedly connected to the side of the clamping rod away from the sleeve. A spring three is sleeved on the outside of the clamping rod. The two ends of the spring three are fixedly connected to the sleeve and the end block, respectively. A slot is opened on the side of the insertion rod away from the bonding plate. An inclined surface is opened on the side of the clamping rod near the slot. The clamping rod is inserted and fixedly connected to the slot.

[0021] By adopting the above technical solution, the insertion rod on one side is inserted into the sleeve on the other side. The insertion rod presses the inclined surface, causing the locking rod and end block to slide outward. The end block stretches the spring three until the locking rod is aligned with the slot. The elastic force of the spring three drives the end block and locking rod to be locked into the slot, which facilitates the splicing and fixing of the two energy storage boxes.

[0022] The inner plate is fixedly installed to the energy storage box by bolts, and the heat sink is pressed against the outside of the electrical equipment.

[0023] By adopting the above technical solution, the inner plate is fixedly installed on the inner wall of the energy storage box.

[0024] Compared with the prior art, the beneficial effects of this invention are that, by setting an auxiliary air guiding component and utilizing the cooperation of components such as horizontal and vertical bars in the drive unit, when cleaning the heat sinks on the outside of electrical equipment, the horizontal and vertical bars can be driven to move synchronously, thereby cleaning the heat sinks around the perimeter simultaneously. Furthermore, by utilizing the cooperation of components such as the U-shaped plate and adjusting scraper in the cleaning unit, the heat sinks on the outer perimeter are cleaned as a whole simultaneously. Simultaneously, regarding the area below the heat sinks, when the U-shaped plate moves forward, the adjusting scraper on one side gradually presses against the heat sink; when it moves in the reverse direction, the scraper on the other side... The adjustable scraper gradually presses against the heat sink fins, improving the cleaning effect on the dust under the fins and accommodating larger amounts of dust. This prevents excessive friction that could hinder the scraper's normal movement. During cleaning, the exhaust fan at the bottom tilts upwards to draw air from the outlet, helping to guide the dust scraped from inside the energy storage tank upwards, facilitating the exhaust of dust-laden gas and improving the cleaning effect on the heat sink fins. After cleaning, efficient and quiet passive cooling of the internal equipment of the energy storage tank is achieved. The specific details are as follows: By incorporating auxiliary air-guiding components and installing filters inside both the air inlet and outlet, cold air enters through the inlet, flows through the electrical equipment, and hot air exits through the top outlet, achieving passive cooling of the electrical equipment inside the energy storage tank. The internal connecting plate and heat sink conduct heat to the electrical equipment, providing auxiliary cooling. Over time, dust accumulates on the outer surface of the heat sink, with more dust adhering to the lower part. At this point, two servo motors are activated. These motors drive a lead screw, which in turn moves a threaded sleeve horizontally. The sleeve moves a crossbar and a push rod, which in turn moves a connecting strip. The push rod pushes the inclined surface of the trapezoidal plate, causing the trapezoidal plate and guide rod to move. The guide rod moves a sliding plate, which in turn moves a longitudinal bar. The sliding plate stretches a spring, causing the longitudinal bar to move its connecting strip, thus achieving synchronous movement of the connecting strips around the perimeter. The connecting strips then move the U-shaped plate below them. The U-shaped plate moves the fixed scraper and the adjusting scraper, which scrape away the dust on the outside of the heat sink. The contact plate is guided by the guide plate, which compresses the spring and moves the slide rod. The slide rod moves the adjusting scraper, and the clamping force of the adjusting scraper on the lower part of the heat sink gradually increases. When the U-shaped plate moves forward, the adjusting scraper on one side gradually clamps the heat sink. When it moves in the opposite direction, the adjusting scraper on the other side gradually clamps the heat sink. This improves the cleaning effect of the dust on the lower part of the heat sink, is suitable for cleaning more dust attached to the lower part, and does not cause excessive clamping friction, which would hinder the normal cleaning movement of the adjusting scraper. During the cleaning process, the exhaust fan at the bottom tilts and draws air upward from the exhaust port, which helps to guide the dust that has been scraped out of the energy storage box upward, so that the dust-laden gas can be discharged outward and treated by the external dust removal device, thus improving the cleaning effect of the heat sink. By setting up splicing components, when two energy storage tanks are spliced ​​together, the two energy storage tanks are kept aligned. Then, the screws on both sides are rotated, which drives the moving sleeves on both sides to move closer to each other. The moving sleeves drive the bonding plate to move, and the bonding plate drives the sleeve and the insertion rod to move. The insertion rod on one side is inserted into the sleeve on the other side. The insertion rod presses the inclined surface, causing the locking rod and the end block to slide outward. The end block stretches the third spring until the locking rod is aligned with the slot. The elastic force of the third spring drives the end block and the locking rod to lock into the slot, which facilitates the splicing and fixing of the two energy storage tanks. This also facilitates the disassembly and transportation of the energy storage tanks. The top cover is fixed to the energy storage tank with bolts, and the inner plate is fixed to the inner wall of the energy storage tank with bolts, which facilitates the overall installation and use.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-3The present invention provides a technical solution: a split-type splicing large heat dissipation box with integrated passive air duct, including two energy storage boxes 1, electrical equipment 9 and a top cover 2 fixedly installed on the top of the energy storage box 1, and a cover 3 fixedly installed on the top of the top cover 2.

[0029] The energy storage box 1 has air inlets 4 on the front and sides, and air outlets 5 on the top of the top cover 2. An auxiliary air guide assembly 6 is installed inside the energy storage box 1, and heat sinks 11 are fixedly installed on the inner wall of the energy storage box 1.

[0030] By utilizing the heat sinks 11 evenly distributed around the outer perimeter of the electrical equipment 9, the internal space of the energy storage box 1 is divided into multiple small spaces, thereby assisting external gas to enter from the air inlet 4 and then be discharged from the air outlet 5, and quickly carrying away the internal heat, thus achieving auxiliary passive air duct heat dissipation.

[0031] The auxiliary air guide assembly 6 includes a drive unit and a cleaning unit. The drive unit is located on the top surface of the top cover 2 and is used to drive the horizontal bar 65 and the vertical bar 610 on the top cover 2 to move. The horizontal bar 65 moves horizontally and the vertical bar 610 moves vertically. The movement of the horizontal bar 65 and the vertical bar 610 is coordinated to drive the cleaning unit around the outside of the electrical equipment 9 to work synchronously.

[0032] Both the horizontal bar 65 and the vertical bar 610 are U-shaped, and the upper and lower parts are fixed by bolts. During subsequent disassembly, the top cover 2, the upper part of the horizontal bar 65 and the upper part of the vertical bar 610 are removed first, then the electrical equipment 9 is removed, and finally the two energy storage boxes 1 can be disassembled and separated.

[0033] The cleaning unit is used to scrape and clean the heat sinks 11 around the outside of the electrical equipment 9. The scraping force during cleaning can be adjusted according to the amount of dust on the outside of the heat sinks 11. By using the heat sinks 11 that are evenly distributed around the outside of the electrical equipment 9, the space inside the energy storage box 1 is divided into multiple small spaces, thereby assisting external gas to enter from the air inlet 4 and then be discharged from the air outlet 5, and quickly carrying away the internal heat, thus achieving auxiliary passive air duct heat dissipation.

[0034] Both the air inlet 4 and the air outlet 5 are equipped with filters. The bottom of the top cover 2 is symmetrically fixed with exhaust fans 8, which are small axial flow fans. The end of the heat sink 11 away from the electrical equipment 9 is fixedly connected to an inner plate 10. The inner plate 10 is made of thermally conductive material and can be an existing heat-conducting plate. Together with the heat sink 11, it guides the heat to the energy storage box 1 and dissipates it outward from the energy storage box 1.

[0035] The inner plate 10 is fixedly installed to the energy storage box 1 by bolts, and the heat sink 11 is pressed against the outside of the electrical equipment 9.

[0036] like Figure 1 and Figures 3-10 As shown, the drive unit includes two mounting boxes 61 fixedly connected to the middle of the top of the top cover 2. A servo motor 62 is fixedly installed inside the mounting box 61. The output end of the servo motor 62 passes through the mounting box 61 and is fixedly connected to a lead screw 63. A screw sleeve 64 is threadedly connected to the outside of the lead screw 63. The bottom of the screw sleeve 64 is fixedly connected to a crossbar 65.

[0037] A push rod 66 is fixedly connected to the outside of the screw sleeve 64, and a fixed vertical plate 67 is fixedly connected to the top of the top cover 2. A guide rod 68 is horizontally and longitudinally slidably connected inside the fixed vertical plate 67. A trapezoidal plate 69 is fixedly connected to the side of the guide rod 68 near the mounting box 61. The push rod 66 abuts against the inclined surface of the trapezoidal plate 69. The trapezoidal plate 69 is fixedly connected to the longitudinal bar 610. A sliding plate 611 is fixedly connected to the end of the guide rod 68 away from the trapezoidal plate 69. The longitudinal bar 610 is slidably connected to the sliding plate 611. A spring 612 is sleeved on the outside of the guide rod 68. The two ends of the spring 612 are fixedly connected to the fixed vertical plate 67 and the sliding plate 611, respectively. The horizontal bar 65 and the longitudinal bar 610 are both slidably connected to the energy storage box 1.

[0038] The cleaning unit includes multiple connecting strips 613, horizontal strips 65, and vertical strips 610, all of which pass through the energy storage box 1 and are fixedly connected to the connecting strips 613 respectively. There are four connecting strips 613 symmetrically arranged and located around the outer perimeter of the electrical equipment 9. A U-shaped plate 614 is fixedly connected to the bottom of the connecting strip 613. The number of U-shaped plates 614 is the same as that of the heat sink 11, and the U-shaped plates 614 are sleeved on the outside of the heat sink 11. Fixed scrapers 615 are fixedly connected to the upper sides of both sides of the inner wall of the U-shaped plate 614, and sliding rods 616 are slidably connected to the lower sides of both sides of the inner wall of the U-shaped plate 614.

[0039] One end of the slide rod 616 is fixedly connected to an adjusting scraper 617, and the other end of the slide rod 616 is fixedly connected to a contact plate 618. A second spring 619 is sleeved on the outside of the slide rod 616. The two ends of the second spring 619 are fixedly connected to the U-shaped plate 614 and the contact plate 618 respectively. The contact plate 618 is located on the outside of the U-shaped plate 614. A guide inclined plate 620 is installed on the side of the contact plate 618 away from the U-shaped plate 614. The guide inclined plate 620 is fixedly connected to the inner plate 10, and the inclination directions of two adjacent guide inclined plates 620 are opposite.

[0040] Example 1: As Figures 3-10 As shown, filters are installed inside both the air inlet 4 and the air outlet 5. Cold air enters from the air inlet 4, flows through the electrical equipment 9, and hot air is discharged from the top air outlet 5, thus achieving passive heat dissipation of the electrical equipment 9 inside the energy storage box 1. The inner plate 10 and the heat sink 11 conduct heat to the electrical equipment 9, playing an auxiliary role in heat dissipation. As the usage time increases, dust will adhere to the outside of the heat sink 11, and the amount of dust adhering to the lower part will be greater.

[0041] By activating two servo motors 62, the servo motors 62 drive the lead screw 63 to rotate. The rotation of the lead screw 63 causes the screw sleeve 64 to move horizontally. The screw sleeve 64 drives the horizontal bar 65 and the push rod 66 to move. The horizontal bar 65 causes the connecting bar 613 on it to slide. The push rod 66 pushes the inclined surface of the trapezoidal plate 69, thereby causing the trapezoidal plate 69 and the guide rod 68 to move. The guide rod 68 drives the slide plate 611 to move. The trapezoidal plate 69 drives the vertical bar 610 to move. The slide plate 611 stretches the spring 612. The vertical bar 610 drives the connecting bar 613 on it to move, thereby realizing the synchronous movement of the connecting bars 613 around the perimeter. The connecting bars 613 then drive the U-shaped plate 614 below them to move.

[0042] The U-shaped plate 614 drives the fixed scraper 615 and the adjusting scraper 617 to move. The fixed scraper 615 and the adjusting scraper 617 scrape away the dust on the outside of the heat sink 11. The contact plate 618 is guided by the guide plate 620, which will compress the second spring 619 and drive the slide rod 616 to move. The slide rod 616 drives the adjusting scraper 617 to move, and the pressing force of the adjusting scraper 617 on the lower part of the heat sink 11 will gradually increase.

[0043] When the U-shaped plate 614 moves forward, the adjusting scraper 617 on one side gradually presses against the heat sink 11. When it moves in the opposite direction, the adjusting scraper 617 on the other side gradually presses against the heat sink 11. This improves the cleaning effect on the dust under the heat sink 11, is suitable for cleaning a lot of dust attached to the bottom, and does not cause excessive friction to hinder the normal cleaning movement of the adjusting scraper 617. During the cleaning process, the exhaust fan 8 at the bottom of the cover 3 will tilt and draw air above the air outlet 5, thereby helping to scrape the dust inside the energy storage box 1 and guide it upward, so that the dust-laden gas can be discharged outward and treated by the external dust removal device (existing flue gas treatment device), thus improving the cleaning effect of the heat sink 11.

[0044] like Figure 1 and Figures 11-13 As shown, a splicing assembly 7 is provided on the side of the energy storage box 1. The splicing assembly 7 includes a mounting plate 71 fixedly connected to the side of the energy storage box 1. A screw 72 is rotatably connected inside the mounting plate 71. A movable sleeve 73 is threadedly connected to the outside of the screw 72. A bonding plate 74 is fixedly connected to the outside of the movable sleeve 73. The bonding plate 74 is bonded to the energy storage box 1.

[0045] A sleeve 75 and a rod 76 are fixedly connected to the side of the bonding plate 74 away from the movable sleeve 73. The sleeves 75 on both sides correspond one-to-one with the rods 76, so that one sleeve 75 can be inserted into the other rod 76. A locking rod 77 is vertically slidably installed on the outside of the sleeve 75.

[0046] An end block 78 is fixedly connected to the side of the clamping rod 77 away from the sleeve 75. A spring 79 is sleeved on the outside of the clamping rod 77. The two ends of the spring 79 are fixedly connected to the sleeve 75 and the end block 78, respectively. A slot 710 is opened on the side of the insertion rod 76 away from the bonding plate 74. An inclined surface 711 is opened on the side of the clamping rod 77 near the slot 710. The clamping rod 77 is inserted and fixedly connected to the slot 710.

[0047] Example 2: Figures 11-13 As shown, when the two energy storage boxes 1 are spliced ​​together, the two energy storage boxes 1 are kept aligned, and then the screws 72 on both sides are rotated to drive the moving sleeves 73 on both sides to move closer to each other. The moving sleeves 73 drive the bonding plate 74 to move, and the bonding plate 74 drives the sleeve 75 and the insertion rod 76 to move. The insertion rod 76 on one side is inserted into the sleeve 75 on the other side. The insertion rod 76 presses the inclined surface 711, causing the locking rod 77 and the end block 78 to slide outward. The end block 78 stretches the spring 79 until the locking rod 77 is aligned with the slot 710. The elastic force of the spring 79 drives the end block 78 and the locking rod 77 to be locked into the slot 710, which facilitates the splicing and fixing of the two energy storage boxes 1, and thus facilitates the disassembly and transportation of the energy storage boxes 1. The top cover 2 is fixedly installed to the energy storage box 1 by bolts, and the inner plate 10 is fixedly installed on the inner wall of the energy storage box 1 by bolts, which facilitates the overall installation and use.

[0048] Working principle: When using this device, firstly, as... Figures 1-13 As shown, cold air enters through the air inlet 4, flows through the electrical equipment 9, and hot air is discharged from the air outlet 5 at the top, achieving passive heat dissipation for the electrical equipment 9 inside the energy storage box 1. By activating two servo motors 62, the servo motors 62 drive the lead screw 63 to rotate. The rotation of the lead screw 63 causes the screw sleeve 64 to move horizontally. The screw sleeve 64 drives the horizontal bar 65 and the push rod 66 to move. The horizontal bar 65 causes the connecting strip 613 on it to slide. The push rod 66 pushes the inclined surface of the trapezoidal plate 69, thereby causing the trapezoidal plate 69 and the guide rod 68 to move. The guide rod 68 drives the sliding plate 611 to move. The trapezoidal plate 69 drives the vertical bar 610 to move. The sliding plate 611 stretches the spring 612, and the vertical bar 610 drives the connecting strip 613 on it to move. This allows the connecting strips 613 around the perimeter to move synchronously. The connecting strips 613 then drive the U-shaped plate 614 below them to move. The U-shaped plate 614 drives the fixed scraper 615 and the adjusting scraper 617 to move. The fixed scraper 615 and the adjusting scraper 617 scrape away the dust on the outside of the heat sink 11. The contact plate 618 is guided by the guide ramp 620. The pressing force of the adjusting scraper 617 against the lower part of the heat sink 11 will gradually increase. When the U-shaped plate 614 moves forward, the adjusting scraper 617 on one side will gradually press against the heat sink 11. When it moves in the opposite direction, the adjusting scraper 617 on the other side will gradually press against the heat sink 11, which improves the cleaning effect of the dust on the lower part of the heat sink 11 and is suitable for cleaning more dust attached to the lower part.
