Coldplate for Use with an Inverter in an Electric Vehicle (EV) or a Hybrid-Electric Vehicle (HEV)

A heat sink for use with an inverter in an electric vehicle (EV) or a hybrid-electric vehicle (HEV), the inverter including a direct current (DC) link capacitor comprising a plurality of film capacitors configured in a stack to form a substantially polygonal prism, the heat sink comprising:

• a first portion configured for attachment to a printed circuit board (PCB) having at least one electronic component attached thereto, the first portion having a perimeter and for dissipating heat generated by the at least one electronic component;
• and
• a second portion oriented along the perimeter of the first portion and forming a conduit, the conduit having a plurality of chambers extending from the perimeter of the first portion and between two of the plurality of film capacitors of the DC link capacitor, the conduit having an inlet and an outlet to facilitate circulation of a coolant through the plurality of chambers of the conduit for dissipating heat generated by the DC link capacitor.
