Title
(EN) LOW-TEMPERATURE LIQUID EVAPORATOR
(FR) EVAPORATEUR DE LIQUIDE A BASSE TEMPERATURE
Abstract
(EN)
A lower header (10) on the side of an inlet for a low-temperature liquid and an upper header (16) on the side of an outlet therefor are connected together via a plurality of external heat transfer pipes (22). In the interior of each external heat transfer pipe (22), an internal heat transfer pipe (24) is provided which extends from the inlet side end of the external heat transfer pipe (22) to a portion thereof which is short of the outlet side end of the mentioned pipe. Between the outer surface of the internal heat transfer pipe (24) and the inner surface of the external heat transfer pipe (22), a low-temperature liquid circulating passage (23) communicating with the interior of the lower header (10) is formed.
(FR)
Un collecteur inférieur (10), situé du côté d'une entrée par laquelle passe un liquide à basse température, et un collecteur supérieur (16), situé du côté d'une sortie par laquelle passe ledit liquide, sont reliés par une pluralité de tuyaux extérieurs (22) de transfert de chaleur. A l'intérieur de chaque tuyau extérieur (22) de transfert de chaleur, se trouve un tuyau intérieur (24) de transfert de chaleur qui s'étend depuis l'extrémité du côté entrée dudit tuyau extérieur (22) de transfert de chaleur jusqu'à une partie de celui-ci se trouvant à une faible distance de son extrémité du côté sortie. Entre la surface extérieure du tuyau intérieur (24) de transfert de chaleur et la surface intérieure du tuyau extérieur (22) de transfert de chaleur, est formé un passage (23) dans lequel circule le liquide à basse température et qui communique avec l'intérieur du collecteur inférieur (10).
