US Patent 11927401 Heat exchange system

A heat exchange system for a gas turbine engine includes a first heat exchanger that defines a first heat source flowpath, a second heat exchanger that defines a second heat source flowpath, and a coolant fluid circuit. The coolant fluid circuit defines a first coolant flowpath that extends through the first heat exchanger and is in thermal communication with the first heat source flowpath, and a second coolant flowpath that extends through the second heat exchanger and is in thermal communication with the second heat source flowpath. The first coolant flowpath and the second coolant flowpath are arranged in a parallel flow configuration.
