The invention relates to a heat exchanger for exchanging heat between a first (HP) and a second (BP) fluids. According to the invention, said exchanger comprises a plurality of modules (15,15a,15b,15c) respectively including an upper plate (17) and a lower plate (19) assembled so as to define, between said plates (17,19), an inner cavity (21) forming a first circulating channel for the first fluid (HP), wherein said exchanger further comprises a housing (3) in which said modules (15,15a,15b,15c) are assembled in order to form said exchanger while defining spaces (33) between said modules, said spaces forming second circulation channels for the second fluid (BP). |

1. A heat exchanger between a first (HP) and a second (LP) fluid, said heat exchanger comprising:
a housing (3) including a housing body (3a) and a lid (3b) fixed to the housing body (3a) inside which is disposed a plurality of modules (15, 15a, 15b, 15c) comprising respectively an upper plate (17) and a lower plate (19) assembled so as to define between said plates (17, 19) an inner cavity (21) forming a first circulation channel for the first fluid (HP), wherein the upper (17) and lower (19) plates of a module (15, 15a, 15b, 15c) respectively have at least one connecting portion (27a, 27b) cooperating with a related adjacent connecting portion (27, 27a, 27b) of a contiguous module (15, 15a, 15b, 15c) or of the housing (3), said connecting portions (27a, 27b) form bosses on the external surfaces (31) of the upper (17) and lower (19) plates, said bosses extending respectively toward the related adjacent connecting portions (27, 27a, 27b), wherein the connecting portions (27a, 27b) form recesses on the internal surfaces (29) having the upper (17) and lower plates (19), and wherein the upper plate (17) and the lower plate (19) include retaining portions (37) disposed interior of the connecting portion (27, 27a, 27b) and configured to improve holding between the plurality of modules (15, 15a, 15b, 15c), said retaining portions (37) forming bosses on the external surfaces (31) of the upper (17) and lower (19) plates extending away from each other and recesses on the interior surfaces (29), and wherein one of said bosses on the external surfaces (31) of one of the upper (17) and lower (19) plates extends toward and contacts another one of said bosses on the external surfaces (31) of the other one of the upper (17) and lower (19) plates, wherein the bosses of the retaining portions (37) having a smaller size than the connecting portions (27, 27a, 27b); wherein at least one second circulation channel for the second fluid (LP) is delimited by the housing (3) and a space (33) between said modules; and wherein the lid (3b) has a tubular discharge orifice (13) for the first fluid (HP) extending inwardly and a tubular feed-in orifice (11) for the second fluid (LP) at the level of the discharge orifice (13) for the first fluid (HP) extending outwardly, and the housing body (3a) has a tubular feed-in orifice (7) for the first fluid (HP) extending inwardly and a tubular discharge orifice (9) for the second fluid (LP) at a level of the feed-in orifice (7) for the first fluid (HP) extending outwardly, for a counterflowing circulation of the first (HP) and second (LP) fluids. |
