The invention relates to a heat exchanger of the brazed plate and fin type including a stack of plates arranged parallel to one another and to a longitudinal direction so as to define, between the plates, a plurality of passages suitable for the flow of at least a first fluid in the longitudinal direction, at least one exchange structure of corrugated shape being arranged between two successive plates and having corrugation crests and corrugation troughs connected alternately by a succession of fins. The fins succeeding one another in a lateral direction which is orthogonal to the longitudinal direction and which defines a direction of corrugation of the exchange structure, and the corrugation crests and troughs being arranged against the plates and having a thickness measured parallel to a direction of stacking which is perpendicular to the longitudinal direction and to the lateral direction.

Device for measuring temperatures in a heat exchanger

In a method for producing a series of at least a first and a second plate-fin heat exchangers, several elongate fluid distribution tanks are installed on the matrix unit, each tank capping just some of the openings assigned to the first fluid and to the second fluid, each tank having its axis in the direction of stacking and each being connected to a pipe so that the number of openings assigned to the first fluid differs from the number of openings assigned to the first fluid, and for preference, the number of openings assigned to the second fluid differs from the number of openings assigned to the second fluid for the at least first and second exchangers of the series.

Method for producing a series of at least a first and second heat exchangers

In a method for producing a series of at least a first and a second plate and fin heat exchanger, each having at least one fluid distribution tank capping at least some of the openings of the matrix unit and which is connected to a pipe, the tank is partitioned into several compartments using at least one partition, so as to distribute the number of openings assigned to a first fluid and to a second fluid, the partition being designed to divide the tank into several compartments which are each connected to a pipe for the passage of the first fluid or of the second fluid and which each communicate with a number of openings that varies according to the configuration adopted by the at least one partition, for the exchanger of the series.
