The invention relates to a heat exchanger that is configured to permit an exchange of heat between a first fluid and a second fluid that circulate in passage paths formed by plates () and fins () of the heat exchanger, the fluids flowing in a multitude of passage channels () each consisting of a closed space () delimited by two adjacent plates and two adjacent fins,

Heat exchanger having optimized fluid passages

A tubular heat exchanger () comprising: a fluid circulation chamber () intended to be supplied with a first fluid, referred to as outer fluid, brought to a first temperature, a heat exchange matrix () housed in said circulation chamber and formed by a plurality of heat exchange tubes () each comprising at least one pair of ducts () nested one inside the other, extending along a direction, referred to as longitudinal direction, and defining: a channel for circulating a fluid, referred to as inner channel (), suitable for being able to be supplied with a second fluid, referred to as inner fluid, brought to a second temperature, and a channel for the circulation of a fluid, referred to as intermediate channel (), and suitable for being able to be supplied with a third fluid, referred to as intermediate fluid, brought to a third temperature, different from said first temperature.
