A method of making and operating a heat exchanger that includes introducing a first fluid into a fluid chamber of a membrane heat exchanger to change the membrane heat exchanger from a flat configuration to a non-flat configuration while the membrane heat exchanger is disposed within a chamber with the membrane heat exchanger extending from a first end to a second end of the chamber and generating a fluid flow of the first fluid within the fluid chamber of the membrane heat exchanger between first and second ends of the membrane heat exchanger, the first fluid generating heat exchange with a second fluid disposed within the chamber. The membrane heat exchanger includes sheets that form a fluid chamber.

A plate for a heat exchanger includes a substantially planar body having a first end, a second end opposing the first end, a fluid surface, and an outer surface. A first cup extends from the outer surface of the body adjacent the first end of the body. A second cup extends from the outer surface of the body and is spaced from the second end of the body.

A heat exchanger includes a body that includes an at least two opposing surfaces and the at least two opposing surfaces are a trapezoidal. The body of the heat exchanger also includes, an area of cross sectional flow channels through the body. The area of cross-sectional flow channels in a direction perpendicular to the bases of the trapezoid increase or decrease between the two bases.
