The apparatus (1), which combines heat transfer between a liquid (8) and a heat-exchanging medium (7) with static mixing of the liquid, comprises internal fittings (2) inside a casing (3). The casing extends longitudinally between a head end (4) and a base end (5). The internal fittings form a heat-transfer and mixing structure. The heat-exchanging medium can be carried from the base end to the head end as an inner stream inside tubes (21, 22) of the internal fittings. The liquid can be carried from the head end to the base end as an outer stream. Reinforcing elements (6, 6', 6") are provided, which stabilize the internal fittings in the longitudinal direction with respect to pressure gradients produced by the liquid. In a main region, the internal fittings are connected by the reinforcing elements to form a non-expandable part-structure (2a); and in a secondary region that is complementary to the main region they remain at least partially unreinforced, as a part-structure (2b) which can expand in the longitudinal direction.

Selon l'invention, l'appareil (1), qui combine un transfert de chaleur entre un liquide (8) et un agent caloporteur (7) avec un mélangeage statique du liquide, comprend des éléments d'aménagement (2) dans une enveloppe (3). L'enveloppe s'étend longitudinalement entre une extrémité de tête (4) et une extrémité de base (5). Les éléments d'aménagement forment une structure de transfert de chaleur et de mélangeage. L'agent caloporteur peut être transporté en tant que flux intérieur dans des tubes (21, 22) des éléments d'aménagement, de l'extrémité de base à l'extrémité de tête. Le liquide peut être transporté en tant que flux extérieur de l'extrémité de tête à l'extrémité de base. Des éléments de renforcement (6, 6', 6'') sont prévus, qui stabilisent les éléments d'aménagement en direction longitudinale vis-à-vis des gradients de pression produits par le liquide. Les éléments d'aménagement sont, dans une région principale, reliés par les éléments de renforcement en une structure partielle (2a) non extensible; dans une région secondaire complémentaire de la région principale, ils demeurent, en tant que structure partielle (2b) longitudinalement extensible, au moins partiellement non renforcés.
