A method and apparatus for pumping and exchanging heat at an accelerated rate between two fluid streams. The apparatus comprises opposite peristaltic pumps moving a separate fluid on their respective side of a linear heat-conductive platen. Each pump consists of a flat elastomeric diaphragm clamped by its edges on the platen; the clamping squeeze displaces the elastomer and makes the diaphragm bulge. Closely spaced pins in combination with fixed cams, flatten and contract the bulge across to form a variable cross-section working chamber. Inlet and outlet are formed by the elastomer bulging into end block cavities leading to ports. In a typical operation, conveyed rollers depress the pins which in turn completely contract the bulge to sealing contact with the platen and form shrinking volumetric chambers, wherein a gas or mixed-phase fluid is compressed progressively on one side of the platen; on the other side similar operation occurs but volumetric chambers circulate a non-compressible liquid. During operation, heat of compression is simultaneously rejected to the cooling liquid through the platen to achieve a near-isothermal process.
