Abrégé

A method for manufacturing a heat exchanger includes joining a first conductive sheet to a second conductive sheet to define a plurality of separate volumes in a blank envelope, creating an aperture in each separate volume in the blank envelope, and heating the blank envelope. The method further includes pressurizing each separate volume through the apertures, hot plastic forming the blank envelope into a formed envelope, and assembling a plurality of formed envelopes into a heat exchanger core, wherein the heat exchanger core includes a fluid passage outside of the formed envelopes, wherein the fluid passage is defined by adjacent formed envelopes, and wherein the fluid passage extends across a dimension of the heat exchanger core.

Abrégé

A system for exchanging heat includes a plurality of adjacent envelopes, wherein each envelope defines a plurality of volumes. A connection between adjacent envelopes provides fluid communication between the volumes in adjacent envelopes, and a fluid passage outside of the envelopes and defined by adjacent envelopes extends across a dimension of the system. A method for exchanging heat includes flowing a plurality of secondary fluids through a plurality of volumes in adjacent envelopes, wherein each secondary fluid flows through a separate volume in each envelope. The method further includes flowing a primary fluid through a plurality of channels outside of the adjacent envelopes and defined by the adjacent envelopes.
