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 ().
