Abstract
Official abstract text for this publication.
An electrified vehicle according to an exemplary aspect of the present disclosure includes, among other things, an electric machine electrically coupled to a battery pack through an inverter. Further, the inverter includes a capacitor with an internal cooling channel. A method is also disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A capacitor for an inverter of an electrified vehicle, comprising: an internal cooling channel having a width dimension and a height dimension, wherein the exterior of the capacitor includes a front face, a rear face, first and second sides, a top, and a bottom, the internal cooling channel includes a plurality of segments, and each segment is parallel to an adjacent one of the front face, rear face, first side, and second side and spaced-apart from the respective adjacent one of the front face, rear face, first side, and second side by an amount substantially equal to the width dimension of the internal cooling channel. 2. The capacitor as recited in claim 1 , further comprising a capacitor bulk located interiorly of the internal cooling channel, and wherein the internal cooling channel is located interiorly of an exterior of the capacitor. 3. The capacitor as recited in claim 1 , further comprising: an inlet and an outlet, the internal cooling channel configured to direct fluid from the inlet to the outlet. 4. The capacitor as recited in claim 1 , wherein the height dimension is greater than the width dimension. 5. The capacitor as recited in claim 1 , wherein the internal cooling channel is concentric with a perimeter of the capacitor. 6. The capacitor as recited in claim 1 , wherein the height dimension of each segment of the internal cooling channel extends perpendicular to the top and bottom and parallel to the respective adjacent one of the front face, rear face, first side, and second side of the capacitor, and wherein the width dimension of each segment of the internal cooling channel extends perpendicular to the respective adjacent one of the front face, rear face, first side, and second side of the capacitor. 7. The capacitor as recited in claim 1 , wherein the plurality of segments includes a first segment spaced-apart from the front face by the amount and extending substantially parallel to the front face, a second segment spaced-apart from the first side by the amount and extending substantially parallel to the first side, a third segment spaced-apart from the rear face by the amount and extending substantially parallel to the rear face, a fourth segment spaced-apart from the second side by the amount and extending substantially parallel to the second side, and a fifth segment spaced-apart from the front face by the amount and extending substantially parallel to the front face. 8. The capacitor as recited in claim 7 , wherein the first segment extends from an inlet of the internal cooling channel to the second segment, and the fifth segment extends from the fourth segment to an outlet of the internal cooling channel.
