A heat exchanger comprises a housing (1) that is closed at two facing ends (2, 3), through which housing a tube bundle extends, which tubes (7) are attached to a tube plate (4, 5) at both ends (2, 3), baffle plates (12) which the tubes (7) are supported spread out at regular intervals between the tube plates (4, 5), a first supply (8) and drain (9) in the housing (1) for a first heat exchange medium, which first medium is lead between that supply (8) and drain (9) according to a prescribed flow pattern by way of the baffle plates (12), as well as a second supply (10) and drain (11) connected to the inside of the tubes (7) for a second heat exchange medium. At least a part of the tube bundle between two successive baffle plates (12) is stabilized with respect to buckling by a supporting means (14) that is located near a baffle plate (12).
Cet échangeur de chaleur comprend un logement (1) qui est fermé à ses deux extrémités (2, 3) se faisant face et qui est traversé par un faisceau de tubes (7), lesquels sont fixés à une plaque porte-tube (4, 5) aux deux extrémités (2, 3); des chicanes (12) dans lesquelles les tubes (7) sont maintenus en support et qui sont réparties à intervalles réguliers entre les plaques porte-tubes (4, 5); une première source (8) et un premier drain (9) situés au niveau du logement (1) pour un premier milieu d'échange thermique, lequel est acheminé entre la source (8) et le drain (9) en fonction d'un diagramme d'écoulement préétabli sous l'action des chicanes (12), ainsi qu'une seconde source (10) et un second drain (11) raccordés à l'intérieur des tubes (7) pour un second milieu d'échange thermique. Au moins une partie du faisceau des tubes entre deux chicanes successives (12) est stabilisée pour éviter le gauchissement à l'aide d'un moyen de support (14) placé à proximité d'une chicane (12).
