[0029] This invention provides an aluminum electrolytic capacitor resistant to ripple current, aiming to solve the problem that existing ripple current resistant aluminum electrolytic capacitors, because each aluminum electrolytic capacitor is an independent unit, can only dissipate heat on the surface of a single aluminum electrolytic capacitor when dealing with ripple current. There is a lack of a structure that can form multiple aluminum electrolytic capacitors into an aggregate structure for efficient heat dissipation. Therefore, it is impossible to dissipate heat from multiple individual units into an aggregate structure at the same time, which reduces the efficiency of the heat dissipation method for ripple current resistant aluminum electrolytic capacitors.

[0030] like Figures 1-6 As shown, an embodiment of this utility model provides an aluminum electrolytic capacitor resistant to ripple current, including a heat insulation structure 1 and a separation structure 2, wherein the separation structure 2 is snapped into the inner side of the heat insulation structure 1.

[0031] The heat insulation structure 1 includes a barrier chamber 11, a vacuum wall 12, a positioning frame cover 13, a limiting base 14, and a cooling fan 15. The vacuum wall 12 is fixedly connected to the surface of the barrier chamber 11, the positioning frame cover 13 is snapped into the top of the barrier chamber 11, the limiting base 14 is fixedly connected to the bottom of the barrier chamber 11, and the cooling fan 15 is fixedly connected to the inside of the limiting base 14.

[0032] In the technical solution of this utility model, by setting up a heat insulation structure 1 and a separation structure 2, the barrier chamber 11 can cooperate with the vacuum wall 12 to form a heat-insulating semi-sealed space, which can block external heat and internal heat. The positioning frame cover 13 can position the separation structure 2, and the limiting base 14 can limit the position of the cooling fan 15, so that the cooling fan 15 can draw cooling air to the separation structure 2 to cool the separation structure 2 and achieve the effect of resisting ripple current. The positioning component 21 can cooperate with the heat dissipation component 22. The positioning component 21 and the heat dissipation component 22 are connected to each other to form a ring-shaped mesh heat dissipation structure, which can efficiently dissipate heat. The dispersed capacitor structure can further dissipate heat to achieve the effect of resisting ripple current.

[0033] Please refer to the following: Figure 4 The separation structure 2 includes a positioning component 21 and a heat dissipation component 22. The positioning component 21 is snapped onto the inner side of the positioning frame cover 13, and the heat dissipation component 22 is snapped onto the surface of the positioning component 21. In this embodiment, by setting the separation structure 2, the positioning component 21 can cooperate with the heat dissipation component 22 to form a ring-shaped mesh heat dissipation structure through the interconnection of the positioning component 21 and the heat dissipation component 22, thereby efficiently dissipating heat itself. Furthermore, the dispersed capacitor structure can further dissipate heat itself to achieve the effect of resisting ripple current.

[0034] For further information, please continue to refer to [link / reference]. Figure 5 The positioning component 21 includes a cylindrical aluminum electrolytic capacitor body 211, a positioning frame 212, and a connecting groove 213.

In this embodiment, by setting the positioning component 21, the cylindrical aluminum electrolytic capacitor body 211 can cooperate with the positioning frame 212 and the connecting groove 213. The positioning frame 212 and the connecting groove 213 limit the heat dissipation component 22, allowing the cylindrical aluminum electrolytic capacitor body 211 and the heat dissipation component 22 to form an integral whole. When the heat dissipation component 22 dissipates heat, the heat at the cylindrical aluminum electrolytic capacitor body 211 can be dissipated together to achieve a high-efficiency heat dissipation effect.

[0035] Please continue to refer to this. Figure 6The heat dissipation assembly 22 includes a sheet aluminum electrolytic capacitor body 221, a connecting shell 222, and a heat dissipation fin ring 223.

In this embodiment, by setting the heat dissipation assembly 22, the sheet aluminum electrolytic capacitor body 221 can cooperate with the connecting shell 222 and the heat dissipation fin ring 223. By installing the sheet aluminum electrolytic capacitor body 221 in the connecting groove 213, the connecting shell 222 and the heat dissipation fin ring 223 can be interconnected to form a ring-shaped mesh structure, which can greatly improve the heat exchange efficiency and increase the ripple current withstand performance of the sheet aluminum electrolytic capacitor body 221.

[0036] Please refer to Figure 2 The bottom of the limiting base 14 is fitted with an intercepting net 16, and the top of the intercepting net 16 is close to the bottom of the cooling fan 15. In this embodiment, by setting the intercepting net 16, the cooling fan 15 can be protected. By intercepting impurities and objects in the air flowing through the intercepting net 16, the air delivery efficiency of the cooling fan 15 can be increased.

[0037] Additionally, please refer to Figure 2 Protective plates 17 are fixedly connected to both the top and bottom of the vacuum wall 12, and the surface of the protective plates 17 is curved. In this embodiment, by setting the protective plates 17, the top and bottom of the vacuum wall 12 can be protected. The curved surface design can effectively protect against external impacts from multiple angles, improving the safety of the edges of the vacuum wall 12 during use.

[0038] Next, please refer to Figure 5 A flow-guiding base 214 is fixedly connected to the bottom of the positioning frame 212, with the bottom of the flow-guiding base 214 close to the top of the cooling fan 15. In this embodiment, by setting the flow-guiding base 214, it can cooperate with the positioning frame 212 to guide the air delivered by the cooling fan 15 to the connecting shell 222 and the heat dissipation fin ring 223, which can further increase the heat exchange efficiency of the connecting shell 222 and the heat dissipation fin ring 223, thereby improving the ripple current resistance of the sheet aluminum electrolytic capacitor body 221 and the cylindrical aluminum electrolytic capacitor body 211.

[0039] Finally, please refer to Figure 5A positioning plate 215 is fixedly connected to the side of the positioning frame 212 near the connecting groove 213. The inner side of the positioning plate 215 engages with the side of the connecting shell 222 near the connecting groove 213.
