Disclosed is a three-fluid heat exchanger () comprising a stack of plates () and: a first circuit () for the circulation of a first heat-transfer fluid between a first inlet manifold () and a first outlet manifold () for the first heat-transfer fluid, a second circuit () for the circulation of a second heat-transfer fluid between a second inlet manifold () and a second outlet manifold () for the second heat-transfer fluid, a third circuit () for the circulation of a third heat-transfer fluid between a third inlet manifold () and a third outlet manifold () for the third heat-transfer fluid, the stack of plates () forming an alternation of first (A) and second (B) circulation spaces for the circulation of heat-transfer fluid, stacked in the direction of stacking of plates (), the first circuit () being arranged within the first circulation spaces (A) and the second () and third () circuits being jointly arranged within the second circulation spaces (B).

Three-fluid plate heat exchanger

The invention concerns a header () for a heat exchanger adapted to have a refrigerant fluid (FR) passed through it and comprising a wall (-) delimiting a chamber () accommodating a device () for distribution of the refrigerant fluid (FR) inside the chamber (), the distribution device () comprising at least one conduit () extending between two ends () along a longitudinal axis (A), at least a first end () of the conduit () being provided with an inlet opening () for the admission of the refrigerant fluid (FR) to the interior of the distribution device (), the distribution device () being provided with at least one orifice () oriented transversely to the longitudinal axis (A) for the evacuation of the refrigerant fluid (FR) from the distribution device () to the chamber (), characterized in that it comprises at least one member () for retaining the distribution device () inside the chamber () at least in part made in one piece with the wall (-) of the header ().

Header of a heat exchanger provided with a member for retention and/or angular positioning of a device for distribution of a refrigerant fluid

The invention concerns a device for distribution of a refrigerant fluid in a header of a heat exchanger comprising at least two conduits (), an external conduit () and an internal conduit (), with the internal conduit accommodated in the external conduit in such a manner as to form a volume () for communication between the internal conduit and the external conduit, the external conduit comprising spraying orifices () each having an axis (A) intersecting a principal lengthwise axis (A) of the external conduit, the internal conduit comprising at least one communication orifice having an axis intersecting a principal lengthwise axis of the internal conduit. According to the invention, the internal conduit () comprises a portion () of reduced thickness formed by removal of material from an external face of the internal conduit (), the external face facing toward the external conduit ().
