INDUCTOR COOLING SYSTEMS AND METHODS
Inductor cooling systems and methods are disclosed. A vehicle may include a transmission case including a coolant inlet and an inductor assembly having a flange extending around a periphery thereof. A thermally conductive cover having a sealing surface may form a seal with the flange. A cavity may be defined between the cover and the inductor assembly and configured to receive coolant from the coolant inlet. A thermal interface material (TIM) may be in contact with a surface of the cover and a surface of the transmission case. The TIM may be a solid or a paste-like substance. If the TIM is solid, it may be in a state of compression between a bottom surface of the cover and the surface of the transmission case. The TIM may transfer heat from coolant in the cavity to the transmission case while the coolant is not being circulated.
