Abstract
A gas turbine engine heat exchange system including a first multi-width channel heat exchanger (MWCHX) configured to transfer heat between a first air stream and a heat transfer fluid. The first MWCHX includes a first plurality of air-passage mini-channels configured to allow passage of the first air stream therethrough, where each air-passage channel has an air-channel width and an air-channel length greater than the air-channel width. The MWCHX also includes a first plurality of heat transfer fluid channels configured to allow passage of the heat transfer fluid therethrough, where each heat transfer fluid channel has a heat transfer channel width and a heat transfer channel length greater than the heat transfer channel width. The heat transfer channel width is less than the air-channel width.
