A configurable electronics cabinet cooling system includes a cabinet having multiple walls including at least one universal cabinet wall. The universal cabinet wall has a planar outward facing surface and multiple apertures. A heat transfer component is releasably connected to the universal cabinet wall. The heat transfer component is selected from either a conductive cooling member or a convective cooling member each adapted to be interchangeably and releasably connected to the universal cabinet wall using fasteners extending through same ones of the apertures. Each of the conductive cooling member and the convective cooling member includes a planar surface, the planar surface adapted to directly contact the outward facing surface of the universal cabinet wall.

An electrical equipment cabinet cooling device includes an electrical equipment cabinet having a cabinet outer frame defining an inner perimeter wall. A planar outer cabinet wall is positioned within the inner perimeter wall. A two-phase thermal device includes spaced and opposed first and second transfer walls. An outer perimeter wall connects the first and second transfer walls and defines an interior sealed cavity between the first and second transfer walls. The outer perimeter wall is sized for slidable receipt within the inner perimeter wall.
