A liquid cooled capacitor includes a disk comprised of a dielectric, e.g., ceramic, material. On both opposite surfaces of the disk are applied a respective electrode. For cooling each of the electrodes, there is a liquid cooling chamber above it. In one embodiment, there is a contact plate at the base of the liquid cooling chamber. The liquid cooling chamber can receive a circulating flow of liquid therein, and the cooling of the contact plate by the liquid will in turn cool the electrodes. Diametrically oppositely positioned liquid connections to the liquid chamber effect cooling liquid circulation. There is a cover spaced away from the contact plate of the cooling liquid chamber which encloses that chamber. The cooling liquid chamber has a peripheral side wall that extends up from the cooling plate to the spaced away cover. In an alternate embodiment, the liquid chamber includes a plurality of annular liquid coolant-carrying tubes. Diametrically oppositely positioned chambers receive the coolant and distribute same among the cooling tubes. In other embodiments, insulating material is applied around the external periphery of the capacitor and outside the disk, the peripheral walls of the cover plates above the electrodes and outside the periphery of the covers themselves.
