Abstract: A heat exchanger has first and second heat-exchange modules including first and second fluid-circulation systems, partition plates sandwiched between first and second heat-exchange modules and each fluidically disconnecting the first and second fluid-circulation systems from one another. At least one of the heat-exchange modules includes a stack of shaped plates superposed along a longitudinal axis, and each consisting of at least one hollowed-out zone passing through it and of a surrounding solid zone of constant thickness, the corresponding fluid-circulation system being defined by the hollowed-out zones of the stack and extending between the adjacent partition plates, at least part of the hollowed-out zone of one of the shaped plates being superposed with a solid zone of another shaped plate adjacent to it, and vice versa.

Abstract: A heat exchanger including: first and second heat-exchange modules comprising fluid-circulation systems, partition plates which fluidically disconnect adjacent fluid-circulation systems, at least one of the heat-exchange modules including: a frame plate of constant thickness, including a through-aperture, and an insert fully housed in the aperture and of a thickness equal to the thickness of the frame plate, and consisting of a single shaped plate or a plurality of shaped plates forming a stack and each consisting of at least one hollowed-out zone passing through it and a surrounding solid zone of constant thickness, the corresponding fluid-circulation system being formed in the hollowed-out zone of the single plate or of each plate of the stack and bounded by the surrounding solid zone or zones and by the adjacent partition plates.

Abstract: A heat exchanger includes first and second modules having first and second systems for circulating first and second fluids respectively, the first fluid comprising different first and second fluid components, partition plates in contact with the adjacent modules and each fluidically disconnecting the first and second circulation systems from one another. Each of the second modules includes a third circulation system, fluidically disconnected from the second circulation system, the first and third circulation systems being fluidically connected through the partition plate. The exchanger introduces a change in phase of the second component by exchanging heat between the first and second fluids and directing the first and second components out of the exchanger through the first and third circulation systems.
