A kind of heat-resisting electrolytic capacitor

Technical field

A kind of the utility model electrolytic capacitor field, and in particular to heat-resisting electrolytic capacitor.

Background technology

Raising with industrial manufacturing level and the popularization in household electrical appliance, the use scope of electrolytic capacitor is also increasingly Extensively.But existing capacitor still has in some defects, such as capacitor that insulation effect is poor between the circuit block of the two poles of the earth, hold Easy puncture short, triggers explosive spalling, or even burning；And due to when capacitor case material is aluminium material, easily being produced during shock Change shape, destroys capacitor element, is also easily caused capacitor short-circuit, triggers explosive spalling, or even burning.In addition, by using warm Electrolyte in the influence of the conditions such as degree, aluminium electrolutic capacitor can evaporate during capacitor life-span, electrically belong to so as to change it Property after, be greatly reduced serviceable bife, thus it is more and more urgent to solve electrolysis capacitor high temperature resistant performance.

The content of the invention

In order to effectively control the temperature of electrolytic capacitor, safety in utilization is reduced, the utility model proposes a kind of structure Simple heat-resisting electrolytic capacitor.

The utility model proposes a kind of heat-resisting electrolytic capacitor, including housing, heat dissipating layer, anode layers of foil, negative electrode layers of foil, Electrolyte layers, sealing-plug and electrode pin, the anode layers of foil, negative electrode layers of foil, electrolyte layers composition curling core body, the anode foils Layer, negative electrode layers of foil difference external electrode pin, the heat dissipating layer is located between housing and curling core body, and crimps the core of core body Portion, the sealing-plug is located between housing and heat dissipating layer.

Further, above-mentioned anode layers of foil, electrolyte layers, negative electrode layers of foil be multilayer be spaced successively stack volume composition curling core Body, increase effectively the contact area of paillon foil, greatly improve the heat dispersion of electrolytic capacitor, meanwhile, above-mentioned curling core body Core filling radiating material, make heat dispersion more preferable.

A kind of heat-resisting electrolytic capacitor that the utility model is provided, it is simple in construction, on the basis of original electrolytic capacitor, The core heat dissipating layer of curling core body, and combination anode layers of foil, negative electrode layers of foil, the mode of electrolyte layers multiple-layer stacked combination are additionally arranged, The heat produced during effective transmission capacitor use, reached preferable radiating effect, universal with homologous series product 125 DEG C of high temperature resistant degree compare, and its heat resisting temperature has reached 145 DEG C, remain in that suitable performance, thus with higher Advantage.

Embodiment

In order that the structure design that the utility model is realized, technical characteristic and using effect are easy to understand, tie below Conjunction is specifically illustrating, and the utility model is expanded on further.

As shown in figure 1, a kind of heat-resisting electrolytic capacitor, including including housing (1), heat dissipating layer (2), anode layers of foil (3), the moon Pole layers of foil (4), electrolyte layers (5), sealing-plug (7) and electrode pin (6), the anode layers of foil (3), negative electrode layers of foil (4), electrolyte layers (5) composition curling core body, the anode layers of foil (3), negative electrode layers of foil (4) difference external electrode pin (6), the heat dissipating layer (2) Between housing (1) and curling core body, and the core of core body is crimped, the sealing-plug (7) is located at housing (1) and heat dissipating layer (2) between.

Further, above-mentioned anode layers of foil (3), electrolyte layers (5), negative electrode layers of foil (4) are that multilayer is spaced stacks volume group successively Into curling core body, the contact area of paillon foil increase effectively.

The utility model designs heat-resisting electrolytic capacitor compared with improved products, simple in construction, occupies little space, and dissipates More preferably, heat resisting temperature reaches 145 DEG C to thermal effect, not only ensure that the service life of electrolytic capacitor, also reduces electrochemical capacitor The failure of device and security risk.
