The apparatus (1), which combines heat transfer between a liquid (8) and a heat-exchanging medium (7) with static mixing of the liquid, comprises int ernal fittings (2) inside a casing (3). The casing extends longitudinally be tween a head end (4) and a base end (5). The internal fittings form a heat-t ransfer 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 th e 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, whic h stabilize the internal fittings in the longitudinal direction with respect to pressure gradients produced by the liquid. In a main region, the interna l fittings are connected by the reinforcing elements to form a non-expandabl e part-structure (2a); and in a secondary region that is complementary to th e main region they remain at least partially unreinforced, as a part-structu re (2b) which can expand in the longitudinal direction. |
