Methods and devices for cooling systems () are provided that are in fluid communication with bleed air from a jet engine compressor. The cooling system can include: a first precooler () receiving bleed air from the jet engine compressor; a heat exchanger () downstream from the first precooler (); a cooling system compressor () downstream from the first precooler (), wherein the heat exchanger () and the cooling system compressor () are in separate flow paths from the first precooler (); a cooling system precooler () downstream from the cooling system compressor (); a VGT cooling system turbine () downstream from the cooling system precooler (); and a discharge conduit () downstream from the cooling system turbine () and the heat exchanger (). A bypass line () for bypassing the turbine can also be included.

A multi-chamber heat exchanger header includes a header housing and an insert. The header housing has a first wall and a second wall generally opposite the first wall where the first and second walls define a track. The insert is positioned to engage with the track such that the insert separates the header into first and second manifold chambers. A method for forming a multi-chamber heat exchanger header includes extruding a header housing having first and second manifold chambers and a track, positioning an insert in the header housing to engage with the track, and welding or brazing the insert to the header housing.
