[0029] In order to make the technical scheme and advantages in the embodiments of the present application clearer and more apparent, the exemplary embodiments of the present application are further described in detail below with reference to the drawings, obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments of the present application. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0030] The embodiment provides a capacitor box.
[0031] The capacitor 2, the first partition plate 3 and the second partition plate 4 are sequentially arranged from bottom to top in the box body 1, the heat dissipation fin 7 is arranged between the first partition plate 3 and the second partition plate 4, the rectifier bridge module 5 and the brake module 6 are arranged above the second partition plate 4, the second partition plate 4 is provided with a through hole, and the rectifier bridge module 5 and the brake module 6 are connected with the heat dissipation fin 7 through the through hole.
[0032] For example, referring to Figure 1 The first partition plate 3 and the second partition plate 4 are arranged on the inner wall of the box body 1, the first partition plate 3 and the second partition plate 4 are horizontally arranged, and the first partition plate 3 and the second partition plate 4 divide the internal space of the box body 1 into three regions: a bottom region, a middle region and a top region.
[0033] Eight capacitors 2 are arranged in the bottom region, and the capacitors 2 are usually heavy, so arranging the capacitors 2 in the bottom region can ensure the overall stability of the box body 1.
[0034] The middle region constitutes an air duct, the heat dissipation fin 7 is located in the middle region, the heat dissipation fin 7 is fixed on the second partition plate 4 by means of bolting or welding, and the heat dissipation fin 7 is spaced apart from the first partition plate 3 by a certain distance, so that the heat dissipation fin 7 can avoid transferring heat to the first partition plate 3, and further avoid transferring heat to the capacitors 2.
[0035] The rectifier bridge module 5 and the brake module 6 are located in the top region, meanwhile, the second partition plate 4 is provided with a through hole, the through hole is aligned with the rectifier bridge module 5 and the brake module 6, so that the rectifier bridge module 5 and the brake module 6 can directly contact the heat dissipation fin 7 through the through hole, that is, the rectifier bridge module 5 and the brake module 6 can be directly arranged on the heat dissipation fin 7, so as to accelerate the heat transfer efficiency. The planar area of the through hole is smaller than the planar area of the heat dissipation fin 7, so that the edge region of the heat dissipation fin 7 can be directly connected with the second partition plate 4.
[0036] Based on the above structure, the capacitor box provided by the embodiment integrates the rectifier bridge module 5 and the brake module 6 in the box body 1, and the rectifier bridge module 5 and the brake module 6 are located above the capacitors 2, so that the land occupation can be fully saved, external equipment can be reduced, the power density is high, and the use cost is reduced. The first partition plate 3 and the second partition plate 4 can constitute an air duct, the heat dissipation fin 7 can dissipate the heat generated by the rectifier bridge module 5 and the brake module 6 into the air duct, which is convenient for subsequent discharge, and can also avoid that the heat source (the rectifier bridge module 5 and the brake module 6) is too close to the capacitors 2.
[0037] On the basis of the above technical scheme, in the technical scheme provided by the embodiment, the sidewall of the box body 1 is provided with a fan 8, and the fan 8 is located between the first partition plate 3 and the second partition plate 4.
[0038] Further, the first air outlet 9 is arranged on the side wall of the box body 1 and located between the first partition plate 3 and the second partition plate 4.
[0039] For example, referring to Figure 1 The fan 8 is arranged on the left inner wall of the box body 1 and located in the air duct and faces the cooling fin 7. Correspondingly, the air inlet is arranged on the left side wall of the box body 1 and aligned with the fan 8. After the fan 8 is turned on, the cold air can be sucked into the box body 1 through the air inlet to cool the cooling fin 7.
[0040] Meanwhile, the plurality of first air outlets 9 are arranged on the right side wall of the box body 1 in a matrix manner and located in the air duct. In this way, the cold air sucked into the air duct by the fan 8 can be discharged from the first air outlets 9 after passing through the cooling fin 7, which is conducive to the rapid circulation of air and improves the cooling effect.
[0041] The left end of the first partition plate 3 is bent downward. On the one hand, it is matched with the Z-shaped distribution of the capacitor 2 to ensure the stability of the capacitor 2. On the other hand, the left end of the first partition plate 3 is bent downward to form a guide slope. The cold air entering the air duct through the fan 8 can be guided upward by the guide slope and concentrated at the cooling fin 7, thereby improving the cooling effect. Of course, in some other embodiments, the left end of the first partition plate 3 can be provided with an upwardly inclined guide slope to guide the wind direction so that the cold air is concentrated at the cooling fin 7.
[0042] In the technical scheme provided in this embodiment, the second air outlet 10 is arranged on the side wall of the box body 1 and located above the second partition plate 4.
[0043] For example, referring to Figure 1 The plurality of second air outlets 10 are arranged on the right side wall of the box body 1 in a matrix manner and located in the top region. In this way, the heat generated by the rectifier bridge module 5 and the brake module 6 can be directly discharged through the second air outlets 10, thereby improving the ventilation and cooling effect.
[0044] In the technical scheme provided in this embodiment, the capacitor 2 is electrically connected with the rectifier bridge module 5 and the brake module 6. The capacitor 2 can store electric energy and supply power to the rectifier bridge module 5 and the brake module 6 when needed.
[0045] The capacitor 2 can be electrically connected with the brake module 6 through the copper bar 11, and the capacitor 2 can be electrically connected with the rectifier bridge module 5 through the copper bar 11.
[0046] The first partition plate 3 and the second partition plate 4 are both provided with a gap slot for the copper bar 11 to pass through.
[0047] For example, referring to Figures 2-3The first partition 3 is provided with two position-allowing grooves, and the corresponding second partition 4 is also provided with two position-allowing grooves. In this way, the copper bar 11 can pass through the first partition 3 or the second partition 4 through the position-allowing grooves, so as to avoid the interference phenomenon between the copper bar 11 and the first partition 3 and the second partition 4, and to cause the capacitor 2 and the rectifier bridge module 5 or the brake module 6 to be unable to be connected smoothly.
