Description

Technical Field

[0001] The present invention relates to the technical field of chip-type aluminum electrolytic capacitors, and in particular to a chip-type aluminum electrolytic capacitor for automotive electronics. Background Art

[0002] A capacitor is an electronic component whose main function is to store charge and electrical energy. When voltage is applied between the two plates of a capacitor, charge accumulates between the plates, forming an electric field, thereby storing electrical energy. As a key electronic component, chip aluminum electrolytic capacitors play an irreplaceable role in the field of automotive electronics. They use aluminum as the anode and form an oxide film on the anode surface as a medium through the electrolysis process. It is then combined with an electrolyte and a cathode, and finally packaged into a chip form for easy SMT (surface mount technology) installation on the circuit board.

[0003] In the patent with publication number CN214254141U, a chip-type aluminum electrolytic capacitor is disclosed, including a capacitor pack and a base. The interior of the capacitor pack includes electrolytic paper, negative electrode foil and positive electrode foil, and the capacitor pack is composed of layers of electrolytic paper, negative electrode foil and positive electrode foil. The surface of the capacitor pack is wrapped with tape, the bottom of the negative electrode foil is fixedly connected to the negative lead, the bottom of the positive electrode foil is fixedly connected to the positive lead, and the bottom ends of the positive lead and the negative lead are fixedly connected to the lead pins. The bottom of the capacitor pack is fixedly installed with a rubber plug, and the surface of the capacitor pack is installed with an aluminum shell, and the inner diameter of the aluminum shell is equal to the diameter of the rubber plug. During the use of this solution, the capacitor does not have the function of heat dissipation. Heat dissipation may be achieved by installing a heat sink or a fan near the capacitor to accelerate heat dissipation by increasing the heat dissipation area or forced convection. This method is inefficient and may not be able to fully dissipate the heat of the capacitor. When the capacitor overheats, its performance may be affected and the service life of the capacitor is shortened.

[0017] 2. The present invention starts the fan, which can blow air downward. The blown air will flow between the large heat sinks, thereby cooling the internal capacitor body, achieving the effect that the capacitor can dissipate heat from the capacitor body.

[0018] 3. The present invention uses a fan to cool the capacitor. Compared with the existing external cooling method, the fan cools the capacitor body alone, which is more targeted and achieves the excellent effect of the capacitor heat dissipation method.

[0019] 4. The present invention puts the frame on the tray, and the protrusions of the rounded plate can be stuck into the small holes of the tray.

The pulley assembly can drive the two threaded rods to rotate simultaneously, so that the circular hole plate slides up and down along the threaded rods. The circular hole plate can scrape off the dust attached to the large heat sink and the small heat sink, thereby ensuring the unobstructed flow of the large heat sink and the small heat sink, achieving the effect of the capacitor being able to clean the heat sink.

[0021] 6. The present invention can push the nail rod plate frame upward through the circular hole plate, and the cylindrical vertical plate can squeeze the bevel gear ring, causing the bevel gear ring to rotate in the clockwise direction, thereby driving the arc scraper to rotate. The arc scraper can scrape the dust on the surface of the fan, achieving the effect that the capacitor can prevent the fan from being blocked.

[0022] 7. The present invention drives the rotating ring to rotate through the threaded rod. The L-shaped rod at the bottom of the rotating ring can clean the dust on the top of the circular hole plate. The barbs of the thin short rod can hook the dust at the bottom of the circular hole plate, so that the dust at the bottom of the circular hole plate accumulates on the thin short rod, thereby ensuring the cleaning function of the circular hole plate and achieving the effect that the capacitor can ensure long-term cleaning function.

[0023] 8. The present invention accumulates dust by using the L-shaped rod at the bottom of the rotating ring and the thin short rod on the stand. It is only necessary to clean the rotating ring and the stand regularly, thereby achieving the effect of convenient cleaning of the capacitor.

[0024] 9. The present invention inserts the U-shaped plate into the bevel frame and inserts the double-headed plate into the U-shaped plate. The U-shaped plate can block the rounded plate and prevent the rounded plate from being pulled, thereby achieving the effect of making the capacitor components more stable.

DETAILED DESCRIPTION

[0041] 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.

[0042] Example 1

[0043] A chip type aluminum electrolytic capacitor used in automotive electronics, such as Figure 1-Figure 3 As shown, it includes a tray 1, a capacitor body 2, a large heat sink 8, a large plate frame 9 and a fan 10. The capacitor body 2 is installed on the tray 1, and the large plate frame 9 is placed on the capacitor body 2. The large plate frame 9 is used to support other components to facilitate overall disassembly. The fan 10 is installed in the large plate frame 9. A plurality of large heat sinks 8 are installed circumferentially at the bottom of the large plate frame 9. The wind blown out by the fan 10 circumferentially flows between the large heat sinks 8.

[0044] In order to prevent the capacitor body 2 from overheating, a large plate frame 9 is placed on the capacitor body 2. The large plate frame 9 can carry a fan 10 and a large heat sink 8, so that the fan 10 and the large heat sink 8 are placed in close proximity on the capacitor body 2. When the capacitor body 2 is working, the fan 10 is started. The fan 10 can blow air downward, and the blown air flows through the large heat sink 8, thereby cooling the internal capacitor body 2.

[0045] like Figure 3 and Figure 4As shown, it also includes a frame 3, a rounded corner plate 4, a round head rod 5, a first return spring 6, a stand 7 and a small heat sink 801. The frame 3 is detachably installed on the tray 1, and multiple rounded corner plates 4 are circumferentially slidably installed on the frame 3. Multiple small holes are opened on the tray 1, and multiple protrusions are provided on the side of the rounded corner plate 4 close to the tray 1. The protrusions of the rounded corner plate 4 fit into the small holes of the tray 1, so that the rounded corner plate 4 can be stuck into the tray 1. The frame 3 is circumferentially fixedly connected with multiple round head rods 5, and the rounded corner plate 4 slides in the round head rods 5. A first return spring 6 is sleeved on the round head rod 5, and the two ends of the first return spring 6 are respectively connected to the round head rod 5 and the rounded corner plate 4. The first return spring 6 is used to press the rounded corner plate 4. The frame 3 is fixedly connected with the stand 7, and multiple small heat sinks 801 are circumferentially installed on the top of the stand 7. The small heat sink 801 is fixedly connected to the large heat sink 8.

[0046] In order to make components such as the fan 10 and the large heat sink 8 more stable, before installation, the frame 3 is put on the tray 1, and the protrusions of the rounded plate 4 can be stuck in the small holes of the tray 1. Because the round head rod 5 is fixedly connected to the frame 3, the first return spring 6 can make the rounded plate 4 close to the frame 3, so that the frame 3 is firmly installed on the tray 1. The frame 3 is connected to the large heat sink 8 through the stand 7 and the small heat sink 801. When disassembly is required, pull the rounded plate 4 to disengage the protrusions of the rounded plate 4 from the small holes of the tray 1, and then the frame 3 can be disassembled. The frame 3 can be disassembled together with all other components except the tray 1 and the capacitor body 2.

[0047] like Figure 5-Figure 7 As shown, it also includes an arc upright plate 11, a circular hole plate 12, a threaded rod 13, a motor 14 and a pulley assembly 15. The arc upright plates 11 are fixedly connected to both sides of the frame 3, and the top of the arc upright plate 11 is fixedly connected to the large plate frame 9. The threaded rod 13 is rotatably installed in the arc upright plate 11, and the circular hole plate 12 is slidably connected between the two threaded rods 13. The circular hole plate 12 can slide along the large heat sink 8 and the small heat sink 801. The motor 14 is installed on the top of the large plate frame 9, and the pulley assembly 15 is connected between the top of the two threaded rods 13 and the output shaft of the motor 14. The motor 14 controls the rotation of the threaded rod 13 through the pulley assembly 15.

[0048] After the capacitor body 2 has been used for a long time, the large heat sink 8 and the small heat sink 801 will be adhered to dust, spider silk and other debris. The dust may cause blockage and affect the heat dissipation function. In order to clean the dust, the start motor 14 drives the pulley assembly 15 to operate. The pulley assembly 15 can drive the two threaded rods 13 to rotate at the same time, so that the circular hole plate 12 slides up and down along the threaded rod 13. The circular hole plate 12 can scrape off the dust attached to the large heat sink 8 and the small heat sink 801, thereby ensuring the smooth flow of the large heat sink 8 and the small heat sink 801.

[0049] Example 2

[0050] On the basis of Example 1, Figure 8 and Figure 9 As shown, it also includes a connecting ring 16, a helical tooth ring 17, an arc scraper 18, a vertical circular plate 19, a thin ring rod 1901, a nail rod plate frame 20, a cylindrical vertical plate 21 and a second return spring 22. The large plate frame 9 is rotatably connected to the connecting ring 16, the outer periphery of the connecting ring 16 is fixedly connected to the helical tooth ring 17, and the bottom of the connecting ring 16 is fixedly connected to the arc scraper 18. The arc scraper 18 can fit and scrape along the air inlet of the fan 10, and the bottom of the arc scraper 18 is fixedly connected to the air inlet of the fan 10. The top is fixedly connected to a vertical circular plate 19, and the outer periphery of the vertical circular plate 19 is fixedly connected to a circular ring rod 1901. Both sides of the large plate frame 9 are slidably connected to a nail rod plate frame 20, and a cylindrical vertical plate 21 is provided on the nail rod plate frame 20. The cylindrical vertical plate 21 is used to move the helical tooth circular ring 17. Both sides of the circular ring rod 1901 are sleeved with a second return spring 22, and the two ends of the second return spring 22 are respectively connected to the large plate frame 9 and the vertical circular plate 19. The second return spring 22 is used to reset the nail rod plate frame 20.

[0051] In order to prevent the fan 10 from being blocked after long-term use, after the orifice plate 12 moves to the top, the orifice plate 12 can push the nail rod plate frame 20 upward, and the cylindrical vertical plate 21 on the nail rod plate frame 20 can squeeze the bevel gear ring 17, causing the bevel gear ring 17 to rotate clockwise, and the bevel gear ring 17 can drive the arc scraper 18 to rotate through the connecting ring 16, and the arc scraper 18 can scrape the dust on the surface of the fan 10. The arc scraper 18 simultaneously drives the vertical circular plate 19 and the circular thin rod 1901 to rotate, so that the second return spring 22 is compressed. When the orifice plate 12 moves downward, the second return spring 22 is reset from the compressed state, thereby driving the component connected to the connecting ring 16 to reset. The bevel gear ring 17 can squeeze the cylindrical vertical plate 21 during the reset process, so that the cylindrical vertical plate 21 drives the nail rod plate frame 20 to move downward and reset.

[0052] like Figure 10-13 As shown, it also includes a thin short rod 23, a limit plate 24 and a rotating ring 25. A plurality of thin short rods 23 are evenly arranged on the stand 7. The thin short rods 23 are located in the gap between the small heat sinks 801. The thin short rods 23 are provided with barbs for hooking the dust at the bottom of the circular hole plate 12. Two limit plates 24 are fixedly connected on both sides of the top of the arc vertical plate 11. Two rotating rings 25, one large and one small, are rotatably connected between the two arc vertical plates 11. A plurality of L-shaped rods are evenly arranged at the bottom of the rotating ring 25. The L-shaped rods are used to hook the dust at the top of the circular hole plate 12. The rotating ring 25 is slidably connected to the limit plate 24. The rotating ring 25 is in contact with the threaded rod 13. The joint between the threaded rod 13 and the rotating ring 25 is prismatic, so that the threaded rod 13 can drive the rotating ring 25 to rotate.

[0053] After long-term use, the circular hole plate 12 will accumulate a lot of dust, spider silk and other debris. In order to ensure the cleaning function of the circular hole plate 12, it is also necessary to clean the circular hole plate 12. The threaded rod 13 can drive the rotating ring 25 to rotate when rotating. After the circular hole plate 12 moves to the top, the L-shaped rod at the bottom of the rotating ring 25 can clean the dust on the top of the circular hole plate 12. After the circular hole plate 12 moves to the bottom, the circular hole plate 12 will contact the thin short rod 23 on the stand 7. The barbs of the thin short rod 23 can hook the dust at the bottom of the circular hole plate 12, so that the dust at the bottom of the circular hole plate 12 accumulates on the thin short rod 23, thereby ensuring the cleaning function of the circular hole plate 12. When cleaning is needed, only the thin short rod 23 and the rotating ring 25 need to be cleaned.

[0054] like Figure 14 and Figure 15 As shown, it also includes a bevel frame 26, a U-shaped plate 27 and a double-headed plate 28. A bevel frame 26 is provided on the outer periphery of the top of the frame 3. The bevel frame 26 is provided with multiple grooves. The bevel frame 26 is slidably placed with multiple U-shaped plates 27 in a circumferential direction. The U-shaped plates 27 fit into the grooves of the bevel frame 26. The grooves of the bevel frame 26 can facilitate the U-shaped plates 27 to be inserted into the bevel frame 26. The U-shaped plates 27 are in contact with the rounded plates 4. Each rounded plate 4 is in contact with two U-shaped plates 27. The U-shaped plates 27 are used to limit the rounded plates 4. The U-shaped plates 27 are slidably placed with double-headed plates 28. The double-headed plates 28 are used to fix the U-shaped plates 27 on the bevel frame 26.

[0055] In order to make the frame 3 more firmly installed on the pallet 1, the U-shaped plate 27 is inserted into the groove of the bevel frame 26, and the double-headed plate 28 is inserted into the U-shaped plate 27. The U-shaped plate 27 can block the rounded corner plate 4 so that the rounded corner plate 4 cannot be pulled. When disassembly is required, just pull the double-headed plate 28, then remove the U-shaped plate 27, and then pull the rounded corner plate 4 for disassembly.
