Abstract

The utility model discloses an electrolytic capacitor with an exposed edge, which comprises an aluminum barrel, a shell, a core covering, a cover plate, an anode leading foot and a cathode leading foot. The cover plate is arranged at the bottom of the aluminum barrel. The shell is sleeved outside the aluminum barrel. The core covering is placed inside the aluminum barrel. The anode leading foot and the cathode leading foot are arranged at the position of the cover plate. The electrolytic capacitor with the exposed edge is characterized in that the top surface of the aluminum barrel is exposed outside the shell. The outer edge of the top of the aluminum barrel extends outwards to form an extending portion. The electrolytic capacitor with the exposed edge has simple structure, quicker heat dissipation speed and high heat dissipation efficiency.

Description

Reveal the limit electrolytic capacitor

Technical field

The utility model relates to and reveal the limit electrolytic capacitor, be specifically related to a kind of limit and expose outer electrolytic capacitor.

Background technology

Traditional electrolytic capacitor is by aluminum barrel, sheath body, core bag, cover plate, and positive leading foot, and negative leading foot constitutes, and the top of aluminum barrel is a flat-top.Electrolytic capacitor its assembling process in or work process in, all to produce heat, heat can directly make capacitor Peng expand, and what of heat can connect serviceability and the useful life that influence electric capacity, and the heat problem of solution capacitor also is the problem that capacitor industry need solve for a long time.

The utility model content

The utility model technical issues that need to address provide reveals the limit electrolytic capacitor, and this kind electrolytic capacitor top cooling surface area is big, rapid heat dissipation.

The utility model technical solution problem can be by taking following technical scheme:

Reveal the limit electrolytic capacitor, comprise aluminum barrel, sheath body, core bag, cover plate, and positive leading foot, negative leading foot, cover plate is located at the bottom of aluminum barrel, sheath body is placed in outside the aluminum barrel, and the core bag is positioned at aluminum barrel, and positive leading foot, negative leading foot are located at the cover plate place, it is characterized in that: the top surface of aluminum barrel exposes to outside the sheath body, the outward flange at the top of the aluminum barrel formation extension that stretches out.

The utility model technical solution problem can also further be taked following corrective measure:

Described extension is provided with aperture.

The utlity model has following technique effect:

The top surface that the utility model reveals limit electrolytic capacitor aluminum barrel exposes to outside the sheath body, the outward flange at the top of the aluminum barrel formation extension that stretches out, extension can increase the surface area at aluminum barrel top, it is contacted fully with outside air, compare with the surface at the top of the average aluminum barrel of prior art, increased the surface area at aluminum barrel top, big more surface area is distribute heat faster, simple in structure, distribute heat efficient height.

Description of drawings

Fig. 1 is that the utility model reveals limit electrolytic capacitor structural representation.

Embodiment

Below in conjunction with specific embodiment the utility model is specifically described.

Embodiment: as shown in Figure 1, reveal the limit electrolytic capacitor, by aluminum barrel 1, sheath body 2, core bag, cover plate, and positive leading foot 3, negative leading foot constitutes, cover plate is located at the bottom of aluminum barrel 1, sheath body 2 is placed in outside the aluminum barrel 1, and the core bag is positioned at aluminum barrel 1, and positive leading foot, negative leading foot are located at the cover plate place, the top surface of aluminum barrel 1 exposes to outside the sheath body 2, and the outward flange at the top of aluminum barrel 1 stretches out and forms extension 4.

Described extension 4 is provided with aperture 5.Aperture helps the end face that air enters aluminum barrel from the side, more helps heat radiation.

Extension can increase the surface area at aluminum barrel top, it is contacted fully with outside air, compare, increased the surface area at aluminum barrel top with the surface at the top of the average aluminum barrel of prior art, big more surface area is distribute heat faster, distribute heat efficient height.

The outward flange that the utility model reveals the top of the limit electrolytic capacitor aluminum barrel formation extension that stretches out, simple in structure, it is faster to dispel the heat, the radiating efficiency height.
