Description

Technical Field

[0001] This utility model relates to a capacitor, specifically a stable heat dissipation type capacitor. Background Technology

[0002] Two conductors placed close together with a non-conductive insulating medium in between constitute a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor stores charge. Capacitors play an important role in circuits such as tuning, bypassing, coupling, and filtering.

[0003] Most large capacitors currently use metal casings for encapsulation to ensure protection of the main capacitor components. At the same time, they can utilize the excellent thermal conductivity of metal for passive heat dissipation. Some capacitors also have ventilation holes punched into the metal casing to achieve air convection between the inside and outside of the metal casing, thereby improving the effect of passive heat dissipation. However, relying on passive heat dissipation makes it difficult to guarantee the stability of capacitor heat dissipation. Although some large capacitors achieve active heat dissipation of the main capacitor components by installing cooling fans inside the metal casing, their top cover is often fixed to the metal casing with rivets, making it inconvenient to disassemble and repair when the cooling fan fails.

[0004] Therefore, we propose a capacitor with stable heat dissipation function. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 In this embodiment of the present invention, a stable heat dissipation capacitor includes a housing 1. Multiple fixing lugs 2 are fixedly connected to both outer walls of the housing 1. A top panel 3 is provided at the top opening of the housing 1. A capacitor body 4 is fixedly installed at the bottom of the top panel 3. Multiple terminal blocks 5 are fixedly passed through the top of the top panel 3, and the bottom ends of the terminal blocks 5 are electrically connected to the capacitor body 4. A grounding post is also fixedly passed through the top panel 3. An air inlet 6 and an air outlet 7 are fixedly passed through the two outer walls of the housing 1, respectively. The inner wall of the housing 1... A first frame 8 is fixedly installed at the corresponding position of the air inlet 6. A cooling fan 9 is inserted through the top opening of the first frame 8. A pressure block 15 is fixedly installed on both sides of the bottom of the upper panel 3, located on the capacitor body 4. The bottom end of one of the pressure blocks 15 abuts against the top end of the cooling fan 9. A positioning hole 16 is provided through the outer wall of the pressure block 15. A locking mechanism is provided inside the box 1. The locking mechanism is adapted to the positioning hole 16. A lever 18 is slidably inserted through the opening slot 17 on the outer wall of the box 1. The lever 18 is connected to the locking mechanism.

[0021] By adopting the above-mentioned solution, when the cooling fan 9 is turned on, the outside air can be quickly entered into the box 1 through the air inlet 6 and quickly discharged through the air outlet 7, so as to provide stable air cooling for the capacitor body 4. When the cooling fan 9 malfunctions, the locking mechanism can be operated by the toggle block 18 to disengage the locking mechanism from the opening slot 17, so that the upper panel 3 and the capacitor body 4 can be removed from the box 1. Then the cooling fan 9 can be pulled out from the first frame 8, which makes it convenient to replace the cooling fan 9. The operation is simple and convenient.

Positioning pins (not shown in the figure) are fixedly installed at the bottom of the upper panel 3 and at the corresponding positions of each insertion hole 25.

[0023] After placing the top panel 3 on the box body 1 and inserting the positioning pin into the corresponding socket 25, the top panel 3 and the box body 1 can be positioned in the horizontal direction, thereby improving the stability of the connection between the two.

[0024] Specific combination Figure 2 and Figure 3 In one embodiment of this utility model, the locking mechanism includes a slide bar 19 located inside the housing 1, and one end of the lever 18 located inside the housing 1 is fixedly connected to the slide bar 19.

A connecting strip 22 is fixedly connected to one side of each pressure block 15 on the outer wall of the slide bar 19, and a locking block 23 is fixedly connected to the corresponding position of the outer wall of the connecting strip 22 and the positioning hole 16.

[0025] By moving the slider 19 by operating the toggle block 18, the locking block 23 can be inserted into or disengaged from the corresponding positioning hole 16, thereby locking or unlocking the upper panel 3 and the box 1. The operation is simple and convenient.

A filter plate 11 is slidably inserted through the top opening of the second frame 10, and a filter hole 12 is provided through the outer wall of the filter plate 11.

[0029] By setting up the filter plate 11 and filter holes 12, the amount of dust and impurities entering the housing 1 from the air inlet 6 and air outlet 7 can be reduced, thereby extending the maintenance cycle of the capacitor. The second frame 10 facilitates the disassembly and assembly of the filter plate 11, making it convenient to clean or replace the filter plate 11.

[0030] Specific combination Figure 2In one embodiment of this utility model, a circuit board 13 is fixedly connected to the inner wall of the box 1 by screws. A temperature sensor 14 is electrically connected to the circuit board 13 by wires. The temperature sensor 14 is attached to the outer wall of the capacitor body 4 with heat-resistant tape.
