Abstract
A closed loop cooling system for electronic equipment. The system includes a cabinet having a top panel, walls, and a door defining an enclosure. A rack is within the enclosure, and the electronic equipment is mounted thereto. An evaporator is within the enclosure below the electronic equipment. Recirculated cabinet airflow warmed by the electronic equipment is directed to the evaporator, cooled by the evaporator, and directed back to the electronic equipment to cool the electronic equipment. A condenser is in fluid communication with the evaporator to circulate coolant therebetween. Ambient airflow from outside the cabinet flows across the condenser to cool coolant flowing therethrough. The recirculated cabinet airflow is maintained independent of the ambient airflow, thereby preventing introduction of added heat or contaminates into the recirculated cabinet airflow, and not affecting air pressure of the ambient airflow.
