Title (EN) HEAT EXCHANGER ESPECIALLY FOR COOLING WATER AT FRESH WATER RECOVERY BY DISTILLATION OF SEA WATER
(FR) ECHANGEUR DE CHALEUR, NOTAMMENT POUR REFROIDIR L"EAU LORS DE L"OBTENTION D"EAU DOUCE PAR DISTILLATION DE L"EAU DE MER
Abstract:
(EN) Heat exchanger intended especially for use at the cooling of water in connection with the recovery of fresh water by distillation of sea water, comprising a plurality of flow elements of substantially plane parallel and vertical relationship. Each flow element consists of two foils (10, 20), which in longitudinal direction of the flow elements so are jointed in several places, that each flow element includes a number of longitudinal gaps (11, 12, 13, 14) defined by discontinuous joints (15) for water transport. At their upper ends the flow elements are attached mechanically to an inlet (17) for heated fresh water from an evaporation chamber, and at their lower ends the elements are attached to an outlet (18) for cooled water to the evaporation chamber. The flow elements are arranged in a basin (60), which is provided with inlets (76-78) for cold sea water below and with outlets (86-88) for heated sea water above the flow elements. The heat exchanger implies that very large heat exchanging surfaces are obtained at low material consumption, thereby rendering the heat exchanger also cheap. The foils (10, 20) preferably are made of plastics and, therefore, have low weight and do not cause corrosion problems.
(FR) Echangeur de chaleur destine specialement a refroidir l"eau lors de l"obtention de l"eau douce par distillation de l"eau de mer, comprenant plusieurs elements a fluide essentiellement plans et paralleles. Chaque element a fluide comprend deux feuilles (10, 20) qui sont fixees ensemble dans le sens longitudinal des elements a fluide en plusieurs endroits de maniere telle que chaque element a fluide presente un certain nombre de couloirs longitudinaux (11, 12, 13, 14) delimites par des joints discontinus (15) pour l"ecoulement de l"eau. Les extremites superieures des elements a fluide sont fixees mecaniquement a une entree (17) d"eau douce chaude provenant d"une chambre d"evaporation et les extremites inferieures des elements sont reliees a une sortie (18) d"eau refroidie menant vers la chambre d"evaporation. Les elements a fluide sont disposes dans une cuve (6) pourvue, a sa partie inferieure, d"entrees (76 a 78) d"eau de mer froide et, a sa partie superieure, de sorties (86 a 88) d"eau de mer chaude. L"echangeur de chaleur permet d"obtenir de grandes surfaces d"echange de chaleur en utilisant peu de matiere, ce qui rend economique la fabrication de l"echangeur de chaleur. Les feuilles (10, 20) sont, de preference, en plastique et sont donc legeres et ne presentent pas de problemes de corrosion.
