DOUBLE-FLOW HEAT EXCHANGER DEVICE

摘要

The invention relates to a device (1) enabling the exchange of heat between a first fluid (2) and a second fluid (3) flowing counter current through the device, comprising: an outer casing (4) sealed against the two fluids, having a long shape that extends between first (7) and second (9) ends; a wall (5) enabling heat exchange between the fluids, housed inside the outer casing; a first inlet (6) for the first fluid (2), formed at the first end (7) of the outer casing; a second inlet (8) for the second fluid (3), formed at the second end (9) of the outer casing (4) opposite the first end (7), the aforementioned exchange wall (5) extending between the first (6) and second (8) fluid inlets; a first outlet (10) for extracting the first fluid (2) from the outer casing (4), formed in the area at the first end (7); a second outlet (11) for extracting the second fluid (3) from the outer casing (4), formed in the area at the second end (9); a first pipe (12) enabling the flow of the first fluid (2) inside the outer casing (4); and a second pipe (13) enabling the flow of the second fluid (3) inside the outer casing (4), such that (i) the second outlet (11) and the first inlet (6) and (ii) the first outlet (10) and the second inlet (8) are separated respectively by a distance equal to or greater than the length (□) of the exchange wall. The invention also relates to the different uses of the device.
