Problems solved by technology

[0010] This custom production of heat exchangers implies high costs and takes a long time to manufacture, which cannot be shortened because custom production does not allow certain raw materials to be procured in advance (plates, corrugated fins, etc.)

Embodiment Construction

[0051] The description and claims will use, without limitation, the terms longitudinal, vertical and transverse adopted with reference to the trihedral frame of references L, V, T shown in the drawings. The stacking direction L of the sheets is perpendicular to the length in the vertical direction V and the width in the transverse direction T of the partition sheets 15 . The separating web is shown in shortened form; in fact, its length in the vertical direction V is much greater than its width in the transverse direction T.

[0052] For various alternative forms of embodiment, the same reference numerals may be used for elements that are the same or that perform the same function in order to simplify the description.

[0053] figure 1 Shown is a heat exchanger 10 of the brazed plate type, which is particularly intended to equip air separation units.

[0054]The heat exchanger 10 comprises a matrix unit 12 comprising a continuous stack of divider plates 15 and corrugated fin...

Abstract

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 said 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.

Description

technical field [0001] The invention relates to a method for the manufacture of a series of heat exchangers consisting of at least a first and a second heat exchanger. The invention also relates to a heat exchanger and an air separation unit comprising the heat exchanger. Background technique [0002] The heat exchanger is a configurable brazed plate heat exchanger for cooling eg at least one fluid intended to be distilled in the air separation unit. [0003] In the design of eg cryogenic heat exchangers it is known practice to use brazed plate heat exchangers, usually made of aluminium. [0004] Typically, a heat exchanger consists of one or more heat exchange matrix units interconnected by fluid distribution piping (manifolds). Each heat exchange matrix unit consists of at least a stack of brazed plates with passages between them and tanks that collect fluid from each passage. The brazed matrix unit includes a continuous stack of plates and corrugated fins, and a plural...
