HEAT EXCHANGER HAVING STACKED PLATES

摘要

The heat exchanger of the invention includes a plurality of stacked plates (2) between which a fluid to be cooled and a coolant flow between two separate circuits defined by said plates (2) in the form of alternating layers, the circuit of the fluid to be cooled including at least one end provided with a tank (7). The heat exchanger is characterized in that said exchanger comprises a first outer blocking half-frame (12, 14) and a second outer blocking half-frame (13, 15) that can be coupled together in a sealed manner, with both of said frames laterally covering the assembly of stacked plates (2) and said blocking half-frames (12-15) being able to define the tank (7) as a single unit, and in that the exchanger includes a flange (8) at the other end of the circuit for the fluid to be cooled opposite the tank (7). The heat exchanger enables the integration of the blocking elements (7, 12-15) of the two circuits and of the connectors for the inlet and the outlet of the fluid to be cooled and the coolant.
