Abstract: A heat exchanger with several plates arranged in parallel is provided. The heat exchanger has a first series of passages for channeling at least one first fluid and a second series of passages for channeling at least one second fluid. The second fluid being in a heat-exchange relationship with at the first fluid. A mixer is arranged in the passage of the first series. The mixer has at least one first channel for the flow of a first phase of the first fluid in a flow direction. The mixer has at least one second channel for the flow of a second phase of the first fluid. The mixer has at least one opening fluidically connecting the first channel to the second channel.
