Recirculation system for parallel ram heat exchangers

A method of performing a heat exchanger cooling mode, comprising:

• receiving, by an inlet line with a first valve, a medium flowing from a low-pressure location of an engine to a chamber;
• dividing in parallel, by the first valve located upstream from a plurality of heat exchangers, the medium across at least a first heat exchanger and a second heat exchanger of the plurality of heat exchangers;
• combining, by a second valve, a flow of the medium exiting out of the secondary heat exchanger with a flow of the medium exiting out of the first heat exchanger;
• and
• recirculating, by a recirculation air system, a recirculation air from the chamber to the inlet line upstream of the first valve and the plurality of heat exchangers to subsequently mix the recirculation air and the medium.
