1. A thermal management system for an engine, the thermal management system comprising:
a thermal circuit, comprising:
a thermal transport bus with a thermal fluid flowing therethrough, the thermal transport bus comprising a first bus segment and a second bus segment, the first bus segment comprising a first thermal load having a first inlet temperature requirement, the second bus segment comprising a second thermal load having a second inlet temperature requirement, the first and second inlet temperature requirements being different; and
a plurality of heat exchangers in thermal communication with the first and second thermal loads, the plurality of heat exchangers comprising a first heat exchanger and a plurality of second heat exchangers, the first heat exchanger on one of the first bus segment or the second bus segment for rejecting heat to engine fuel of the engine, wherein one of the plurality of second heat exchangers is on the first bus segment and another one of the plurality of second heat exchangers is on the second bus segment;
wherein the thermal fluid is split between each of the first and second bus segments such that only a portion of the thermal fluid flows through the first heat exchanger to accommodate the first and second inlet temperature requirements being different.
