ABSTRACT:
The invention relates to a hydraulic circuit element (20) for heat exchange between a first fluid and a second fluid, which defines a path for the first fluid and comprises at least one tube (22) having two ends and at least one tip (24) at one of said ends of the tube (22), said tip having at least one communicating passage (28b) that defines the path of the first fluid. The invention also relates to a heat exchanger obtained by stacking circuit elements (20). Such a heat exchanger can be used in particular in motor vehicles.
