- the pairs of plates of the second type are, they, configured to allow the circulation of the first fluid between the first and third intermediate collectors 53, 55, at the pass 25c.
- the passes 25a and 25b comprise pairs of plates 3 of the first type while the pass 25c comprises at least one pair of plates 3 of the second type and, possibly, pairs of plates of the first type.
- the secondary plates 3b are advantageously identical in all the passes and therefore regardless of the type of pairs of plates 3, except to be provided with a partition 57, as developed later.
- the primary plate 3a is provided on its front with a stamp formed of a convex region 65 intended to be in contact with the back of a secondary plate 3b, at said plane region 67 of it.
- said curved region 65 of the primary plate 3a is arranged between the first 130 and second 150 part of said plate 3a, at the level of the intermediate ports 69b, 75, 73.
- the plane region 67 of the secondary plates 3b is arranged between the portion 130 and the portion 150.
- said convex region 65 extends substantially transversely from one of the lateral edges 34 to the other of the lateral edges 34 of the primary plate 3a, so that the direct passage of said first fluid is made impossible from the first zone 13 to the second zone 15.
- said convex region 65 of the primary plate of the first type 3a 'and said flat region 67 of the secondary plate are designed, by their junction, to prevent the circulation of the first fluid between on the one hand the first part 13 and secondly the second intermediate orifice 69b and the first intermediate orifice 75, while allowing the circulation of the first fluid between the first zone 13 and the orifice 73 as well as between the second intermediate orifice 69b and the second zone 13.
- said curved region 65 of the primary plate of the first type 3a 'and said plane region 67 of the secondary plate 3b are designed, by their junction, to prevent the circulation of the first fluid between on the one hand the first zone 13 of the beam 1 and secondly the first and second intermediate manifold 55, 51b.
- said convex region 65 first bypasses the plane region 69b "and said second intermediate orifice 69b so as to isolate said second intermediate orifice 69b from the first portion 13.
- the orifice 75 and the flat region 75 are then completely surrounded by the domed region 65 so that said orifice 75 is designed to be insulated from both the first portion 13 and the second first portion 15.
- the domed region 65 bypasses the region 73 "and the third intermediate orifice 73 so as to separate said third intermediate orifice 73 of the second portion 15 of the primary plate of the first type 3a '.
- the pairs of the second type differ from the pairs of the first type in that, here, said curved region 65 of the primary plate of the second type 3a "is this time designed for, by its junction with the plane region 67 of the secondary plate 3b, allow the direct flow of the first fluid between the first zone 13 and the first intermediate manifold 55.
- the primary plates of the second type 3a are designed so to allow a passage between the first zone 13 and the bottle 11.
- said convex region 65 of the primary plate beta 3a "first bypasses the plane region 69b" and said second intermediate orifice 69b so as to isolate said second intermediate orifice 69b from the first Part 13.
- the plane region 75 "and the first intermediate orifice 75 are then separated from the second portion 15 of the primary plate of the second type 3a" by the curved region 65.
- the plane region 73 "and the third intermediate orifice 73 are also separated from the second part 15 of the primary plate of the second type 3a "by said convex region 65.
- the secondary plate 3b differs from that illustrated in FIG. 5 in that the orifice 73 is here provided with one of the said partition 57.
- the beam 1 comprises at least such a plate 3.
- the partition wall 57 are for example derived from material with the convex region 73 '.
- the circulation of the second fluid does not depend on the type of pair of plates 3.
- the same type of passage is defined guiding the second fluid from the inlet manifold of the second fluid to the outlet manifold of the second fluid.
- each fluid within a pair of plates is constrained by the junction of the front of a domed region of one of the plates 3 with the back of a flat region of a plate 3 adjacent, said fluid being forced to bypass said junction.
- the contact zone between one of the curved regions and the flat surface is inaccessible to said first and second fluid.
- said curved region 65 is designed to prevent a direct flow of the first fluid from one manifold to another.
- said curved zone 65 is furthermore designed so as to prevent the circulation of the first fluid, between two plates 3 of the same pair, from an intermediate orifice to another intermediate orifice, except at the level of the pairs of the second type. .
- Said plates 3 may also be provided with corrugations 77 on the bottom of the plate arranged so as to create disturbances in the fluids and / or points of contact between the plates 3. Said corrugations thus make it possible to improve the exchange of heat between the first fluid and the second fluid.
- the first zone 13 of the heat exchanger defines a single-pass configuration. This configuration is here obtained using only secondary plates 3b, all provided with partition walls 57, as illustrated in FIG. 7, and primary plates of the second type 3a "as illustrated in FIG. , as illustrated in FIGS. 10 and 11, it is possible to use plates 3 which have no third intermediate orifice.
- the other characteristics of the one-pass heat exchanger are similar to those of the three-pass heat exchanger.
