1. A cooling system for contactors, each contactor has a first end mounted to a base of a chassis and a second end having a first contactor terminal and a second contactor terminal, two contactors form a contactor pair for a DC interface, the first contactor terminal of a first contactor of the contactor pair being connected to a first busbar and the second contactor terminal of the first contactor of the contactor pair being connected to a second busbar, the first contactor terminal of a second contactor of the contactor pair being connected to a third busbar and the second contactor terminal of the second contactor of the contactor pair being connected to a fourth busbar, the cooling system comprising:
a cover configured to be mounted to sidewalls of the chassis, when mounted, the cover has an interior side facing the base of the chassis and an exterior side opposite the interior side, the cover comprising:
a first flow channel extending in a first direction between a first end and a second end of the cover, the first flow channel connectable to a fluid source; and
a plurality of thermally conductive bosses projecting from the interior side of the cover, each of the plurality of thermally conductive bosses being configured to contact at least one of a respective one of a first busbar, a second busbar, a third busbar, and a fourth busbar via an electrically insulating member, wherein at least one of the plurality of thermally conductive bosses is offset in a second direction from the first flow channel, the second direction being perpendicular to the first direction, wherein the cover is thermally conductive.
