Abstract: A rack-mountable heat-exchanger for modular electronic systems is provided that include a heat exchanger including ambient air inlets and outlets forming an ambient airflow path in a first direction, and recirculating air inlets and outlets forming a recirculating airflow path in a second direction perpendicular to the first direction separated from the ambient airflow path; housing for an electronic device, the housing including internal air inlets and outlets forming an internal airflow path; a first duct configured to link the recirculating air outlet to the internal air inlet; a second duct configured to link the recirculating air inlet to the internal air outlet; and fan assemblies located one of the airflow path, configured to propel air through the heat exchanger in the respective airflow path.
