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 relates to an adapter () for connecting a header () of a heat exchanger (i) having a header cross section () to a manifold () having a manifold cross section () which has a different shape from the shape of the header cross section (). An adapter () connects the header cross section () to the manifold cross section (). The adapter () can be in one piece with a first end plate () of the heat exchanger (i) or it can be an independent part. Application to plate heat exchangers.

Adapter for a heat exchanger header

The invention relates to a heat exchanger () plate () intended to delimit at least one channel () for circulation of a fluid, the circulation plate () being provided with a bottom () and a raised rim (-) that surrounds the bottom (), the circulation plate () comprising at least one opening (-) through which a fluid can enter the channel (), characterized in that the opening (-) is delimited by at least one at least partially rectilinear edge (). Application to the field of heat exchanges.

Heat exchanger plate with optimized opening

The invention relates to a plate () forming part of a heat exchanger and intended to delimit at least one channel () for circulation of a fluid. The plate () extends principally along an axis of longitudinal extent (A). The plate () comprises at least one bottom (), at least one first lateral raised edge () which is inscribed within a first plane (P) intersecting the axis of longitudinal extent (A), and at least two openings () which are configured such that the fluid enters and exits the channel (), respectively. The bottom () is provided with a rib () which extends longitudinally from the first lateral raised edge (). The rib () is positioned between the two openings (). The rib () is of a sinuous configuration.

Plate forming part of a heat exchanger, and heat exchanger comprising at least one such plate

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 ().

Refrigerant fluid distribution device intended to be accommodated in a header of a heat exchanger

A thermal battery including a storage vessel as well as an inlet pipe and an outlet pipe for a fluid that are connected to a circulation circuit is disclosed. The thermal battery also has at least two shut-off valves placed on the inlet pipe and the fluid outlet pipe, respectively, to isolate the fluid contained in the storage vessel when the circulation circuit of the fluid is shut off. The shut-off valves are automatic and include an enclosure containing the fluid and including an inlet and an outlet for the fluid, and a float that is moveable between: an upper position in which the float floats and obstructs at least the outlet when the circulation circuit is shut off, and a lower position in which the float is submerged and allows the fluid to flow between the inlet and the outlet when the circulation circuit is operational.

Thermal battery with shut-off valve

The evaporator () for a motor vehicle air conditioning device comprises at least one refrigerant tube (A) intended to allow the circulation of a refrigerant fluid and at least one storage member () comprising at least one housing () comprising a material referred to as a thermal storage material () intended to store frigories and release them to a ventilation fluid intended to circulate towards an interior of the vehicle. The housing () has a substantially hemispherical shape.
