Abstract:
A coldplate for use with an inverter in an electric vehicle (EV) or a hybrid-electric vehicle (HEV). The inverter includes a direct current (DC) link capacitor comprising multiple film capacitors configured in a stack. The coldplate includes a first portion configured for attachment to at least one electronic component, the first portion having a perimeter and for dissipating heat generated by the electronic component. The coldplate includes a second portion oriented along the perimeter of the first portion and forming a conduit, the conduit having a chamber extending from the perimeter of the first portion and between two of the plurality of film capacitors of the DC link capacitor. The conduit has an inlet and an outlet to facilitate circulation of a coolant through the chamber of the conduit for dissipating heat generated by the DC link capacitor.
