Abstract:
A capacitor that has the features of heat dissipation and energy conservation comprises a capacitor core, an aluminum shell surrounding the capacitor core, the aluminum shell is covered with rubber that completely covers the top of the capacitor core, then with the use of an extruding machine, the upper orifice of the aluminum shell is extruded and sealed up around the rubber completely; the outer surface of the aluminum is formed with an aluminum oxidized insulating layer after the aluminum shell is processed through an aluminum metal surface transformation treatment, since the aluminum shell is not covered with plastic film (or sleeve), heat dissipation is enhanced; in addition, since plastic film or sleeve is not used, no pollution is occurred, and hence more friendly to the environment; furthermore, since heat generation is low, energy is conserved.
