Abstract
The invention relates to a heat exchanger assembly having two exchangers, each comprising a stack of parallel plates defining a first connection surface and a second connection surface that are adjacent to each other. The heat exchanger assembly can also include an enclosure between the first connection surface and the second connection surface, primary compartments in the enclosure configured to channel primary fluid through the first connection surface and the second connection surface, and a secondary compartment in the enclosure for channeling secondary fluid.
Claims16
A heat exchanger assembly for forming a heat transfer unit without contact between a primary fluid and a secondary fluid, the heat exchanger assembly comprising a first exchanger and a second exchanger, wherein the heat exchanger assembly is configured to exchange heat between at least one primary fluid, and at least one secondary fluid, wherein:
- each exchanger comprises a stack of several plates arranged parallel to one another in a so-called stacking direction, so as to delimit at least i) primary passages configured for the flow of primary fluid and ii) secondary passages configured for the flow of secondary fluid, the primary passages and the secondary passages following one another according to a predetermined stacking pattern,
- the stack of the plates of the first exchanger defines a first connection face fluidically linked to the primary passages of the first exchanger, the stack of the plates of the second exchanger defines a second connection face fluidically linked to the primary passages of the second exchanger, wherein the first exchanger and the second exchanger are arranged such that the first connection face is adjacent to the second connection face,
- wherein the heat exchanger assembly further comprises:
- an enclosure delimited by the first connection face, by the second connection face and by an enclosure volume extending between the first connection face and the second connection face;
- a plurality of primary compartments arranged in the enclosure volume to channel all or part of the primary fluid between the first exchanger and the second exchanger through the first connection face and the second connection face, wherein the primary compartments are formed by primary ducts which each extend between the first connection face and the second connection faces and parallel to the stacking direction;
- and
- a plurality of secondary compartments distinct from said plurality of primary compartments which are arranged in the enclosure volume to channel all or part of the secondary fluid between the first exchanger and the second exchanger through the first connection face and the second connection face,
- wherein each secondary compartment is formed by the walls of the enclosure and by the walls of two successive primary ducts.
