Title (EN) EXTERNAL LOOP NONFREEZING HEAT EXCHANGER
(FR) ECHANGEUR DE CHALEUR QUI NE GELE PAS, A BOUCLE EXTERNE
Abstract: front page image
(EN) This invention is directed to an external loop nonfreezing heat exchanger for cooling a heat transfer fluid with cryogenic fluid (10;210). The cryogenic fluid (10,210) is first pre-vaporized wit h the spent cryogenic fluid (16). The heat transfer fluid is then cooled by the vaporized cryogenic fluid (16) instead of the cryogenic fluid feed (10,210) directly.
(FR) L'invention concerne un échangeur de chaleur qui ne gèle pas, à boucle externe, destiné au refroidissement d'un fluide caloporteur à l'aide d'un fluide cryogénique (10, 210). Le fluide cryogénique (10, 210) est d'abord préalablement vaporisé avec le fluide cryogénique utilisé (16). Le fluide caloporteur est ensuite refroidi par le fluide cryogénique vaporisé (16) au lieu d'être directement refroidi par l'alimentation en fluide cryogénique (10, 210).
