Abstract
The invention concerns a device for distribution of a refrigerant fluid in a header of a heat exchanger comprising at least two conduits (12, 13), an external conduit (12) and an internal conduit (13), with the internal conduit accommodated in the external conduit in such a manner as to form a volume (14) for communication between the internal conduit and the external conduit, the external conduit comprising spraying orifices (120) each having an axis (120A) intersecting a principal lengthwise axis (12A) 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 (13) comprises a portion (16) of reduced thickness formed by removal of material from an external face of the internal conduit (13), the external face facing toward the external conduit (12).
