Thermal conductor for electric vehicle (EV) or a hybrid vehicle (HEV) of the inverter

Abstract

Thermal conductor for electric vehicle (EV) or a hybrid vehicle (HEV) in the inverter, the inverter includes a DC link capacitor, the DC side capacitor having a stacked plurality of substantially polygonal prism arranged to form film capacitor. Each thin film capacitor having orthotropic properties. A first thermal conductor having a substantially planar member and a second substantially planar member, a first substantially planar member configured to contact the first side of a polygonal prism is formed in a thin film capacitor, and a second substantially planar the member is configured to contact the first side of the rectangular prism of polygonal prism opposite second side, a second side of the rectangular prism formed by another film capacitors. A first planar member and second planar member is thermally conductive to dissipate heat generated by the film capacitor, connected to the connector is attached to each other, and have sufficient stiffness to constrain expansion of a thin film capacitor on its thickness.
