Water-cooled motor controller

A water-cooled motor controller, comprising:

• a controller housing;
• a capacitor within said controller housing;
• a water-cooled plate within said controller housing above said capacitor;
• and
• a power module stacked within said controller housing above said water-cooled plate,
• wherein said power module is fixedly connected to said water-cooled plate,
• wherein said water-cooled plate is comprised of a side facing said power module with a cooling medium flow channel and an opposite side facing away from said power module and being in contact with said capacitor through an insulating and thermally conductive material for heat exchange,
• wherein said water-cooled plate and said controller housing are fixedly connected to each other with a cooling medium passage provided therebetween so as to flow a cooling medium through said cooling medium passage in a heat exchange relationship with said water-cooled plate,
• wherein said cooling medium passage is provided with a sealing component on a contact interface between said controller housing and said water-cooled plate, and
• wherein said sealing component is an O-ring.
