The utility model relates to a novel high -pressure safety explosion -proof film -coated
capacitor shell, its characterized in that: the shell includes
aluminium base layer, film layer, the shell inside is provided with the cavity for accommodating
nucleon, the cavity one end is provided with the opening, the
aluminium base layer outer
peripheral surface covers film layer, film layer and
aluminium base layer outer
peripheral surface are combined integrally and form the shell. Through adopting a kind of to melt
liquid state coating hot-pressing formation in aluminium base layer obtains novel high -pressure safety explosion -proof film -coated shell, solves the technical
bottleneck of the existing
solid-state film pasting process, can obviously improve the peel strength between film layer and aluminium base layer, solves the problem that film layer appears to fall off or bulge on the surface of aluminium shell in
processing or high temperature environment, reduces process yield. It can be applied to the high -
voltage aluminium
electrolytic capacitor of
voltage greater than 400V, is applicable to AI
server, electric automobile, photovoltaic
energy storage, communication equipment,
artificial intelligence and other national strategic emerging industries have extensive market demand.
