Refreshing heat management fluid in a turbomachine

Abstract:

A heat management system for a turbomachine may include a first heat exchanger configured and arranged to receive a first fluid stream from a first duct, a second heat exchanger configured and arranged to receive the first fluid stream after discharging from the first heat exchanger, and a second duct fluidly communicating with the first duct between the first heat exchanger and the second heat exchanger to introduce a second fluid stream from the second duct to the first duct. A method of cooling fluid streams may include directing a first fluid stream from a first duct across or through a first heat exchanger, directing the first fluid stream across or through a second heat exchanger after discharging from the first heat exchanger, and directing a second fluid stream from a second duct to the first duct, with the second duct fluidly communicating with the first duct between the first heat exchanger and the second heat exchanger.
