Coldplate with integrated DC link capacitor for cooling thereof
First Claim
Patent Images
1. An assembly comprising:
- a capacitor having a plurality of film capacitors, wherein the capacitor is not encapsulated within its own casing such that the film capacitors are exposed to an environment external to the capacitor;
a coldplate including a coldplate member including a pocket configured to receive the capacitor therein, the pocket being sized to surround the capacitor when the capacitor is received within the pocket to thereby provide physical integration of the capacitor in the coldplate member;
wherein the capacitor is received within the pocket to thereby be physically integrated in the coldplate; and
a potting material received within the pocket, the potting material substantially surrounding the film capacitors of the capacitor, wherein the potting material facilitates heat transfer from the film capacitors to the coldplate member via the pocket, provides electrical isolation to the film capacitors, and mechanically supports the film capacitors.

Abstract
A coldplate for use with an inverter of an electric vehicle includes a coldplate member. The coldplate member includes a pocket configured to receive a DC link capacitor of the inverter therein. The pocket is sized to surround the DC link capacitor when the DC link capacitor is received within the pocket to thereby provide physical integration of the DC link capacitor in the coldplate member.

6. An assembly for an electric vehicle, the assembly comprising:
-
an inverter including a naked DC link capacitor having a stack of film capacitors and lacking an encapsulation housing such that the film capacitors are exposed to an environment external to the naked DC link capacitor; a coldplate including a coldplate member having a pocket; wherein the naked DC link capacitor is received within the pocket to thereby be physically integrated in the coldplate; and a potting material received within the pocket, the potting material substantially surrounding the film capacitors of the naked DC link capacitor, wherein the potting material facilitates heat transfer from the film capacitors to the coldplate member via the pocket, provides electrical isolation to the film capacitors, and mechanically supports the film capacitors. - View Dependent Claims (7, 8, 9)
