A heat exchanger includes a plurality of flexible spiral tubing coils (12, 14, 16, 18, ...) hydraulically connected to inlet and outlet manifolds (24, 22) mounted in spaced, parallel relationship to each other in vertical array within a tank. The coils are alternately wound clockwise and counterclockwise, and the innermost 12B, 14B, ...) and outermost (12A, 14A, ...) turns of the spiral coils are selectively connected to the appropriate manifolds, so that the flow in one coil runs counter to those adjacent to it, resulting in a reduction of localized temperature gradients due to a temperature averaging effect in the fluid within the tank which lies between adjacent coils.
Echangeur de chaleur comprenant plusieurs tubes flexibles bobinés en spirale (12, 14, 16, 18, ...) reliés hydrauliquement à des tubulures d'entrée et de sortie (24, 22) montées séparées et parallèles dans un réseau vertical à l'intérieur d'un réservoir. Les tubes sont alternativement bobinés dans le sens horaire et antihoraire et leurs spires les plus internes (12B, 14B, ...) et les plus externes (12A, 14A, ...) sont sélectivement raccordées aux tubulures appropriées de façon à ce que le flux traversant une bobine soit à contre-courant de celui de la bobine contiguë d'où une réduction des gradients locaux de température due à l'effet d'égalisation de la température du fluide du réservoir situé entre deux bobines contiguës.
