Equipment category • Equipment category
Rack-mounted coils that remove heat from server exhaust using a facility or secondary liquid loop.
Role in the thermal chain
Rear-door heat exchangers provide a retrofit-friendly bridge between air-cooled servers and liquid heat rejection. Passive and active designs differ in fan use and supported airflow.
