An equipment assembly for cooling heat-generating electrical components is disclosed. The assembly includes a housing for containing a heat-generating electrical component. The housing includes an open end having a planar area. A closed-loop liquid cooling system includes a liquid coolant conduit in proximity to the heat-generating electrical component. The conduit allows circulation of a liquid coolant to extract heat from the heat-generating electrical component. A heat exchanger is fluidly coupled to the liquid coolant conduit to extract heat from circulated liquid coolant within the heat exchanger. The heat exchanger includes a shaped front facing the open end of the housing. The surface area of the shaped front is greater than the planar area of the open end. An air flow system propels ambient air through the shaped front of the heat exchanger.
