Heat exchangers with modular cores and methods of making the same

A heat exchanger assembly comprising:

• a structural support forming an arch comprised of a plurality of rectangular components coupled at their adjacent ends at a slight obtuse angle wherein the structural support has a plurality of first mating interfaces wherein the plurality of first mating interfaces has a plurality of input ports and a plurality of output ports;
• and
• an array of heat exchanger cores wherein each heat exchanger core in the array of heat exchanger cores comprises:
• one or more second mating interfaces;
• at least one core input port and at least core output port;
• wherein each heat exchanger core in the array of heat exchanger cores is rigidly affixed in a removable configuration to the structural support by coupling with a face seal the one or more second mating interfaces with one or more first mating interfaces from the plurality of first mating interfaces such that the at least one core input port fluidly couples to a first output port in the plurality of output ports and the at least one core output port fluidly couples to a first input port in the plurality of input ports.
