This engineering effort is to reverse engineer the core of the B?2 Sink Heat Exchangers, develop disassembly process to remove defective cores, develop a stacking, vacuum brazing and welding process to manufacture new heat exchanger cores and to develop a welding process to install the new cores on existing B?2 Sink Heat Exchangers. The requirement includes reverse engineering the re?core process for the B?2 Sink Heat Exchanger (Sink HX). The B?2 Sink Heat Exchanger (NSN 1660?01?262 5588FW) is a Ethylene Glycol Water (EGW) to air HX located in the A/C secondary airflow system above the A/C engines. Sensors within the ECW system sense when the temperature of the EGW fluid entering the equipment, pack and routes some or all of the EGW fluid through the sink HX. The deliverables will include all technical data related to the heat exchanger disassembly, all technical data related to the cores, all technical data related to the stack up, vacuum brazing and installation of the cores on existing units.
