Abstract

L’invention concerne un système de régulation de la température d’un fluide cryogénique, comprenant une conduite (1) de circulation du fluide cryogénique (A), comprenant une branche principale (12) dans laquelle une partie (A2) du fluide cryogénique circule à une température initiale (Ti) et une branche de dérivation (11) dans laquelle une autre partie (A1) du fluide cryogénique est refroidie à une température finale (Tf) inférieure à la température initiale (Ti), de sorte à former un mélange desdites parties (A1, A2) du fluide cryogénique à une température (Tm) comprise entre la température finale (Tf) et la température initiale (Ti), ledit système étant caractérisé en ce que la branche principale (12) comprend une canalisation (8) comprenant successivement une partie convergente (8a), un col (8b) de section inférieure à celle de la conduite (1) et une partie divergente (8c) et en ce que la branche de dérivation (11) est raccordée à ladite canalisation (8) par un raccord amont (80) situé en amont de la partie convergente (8a) et par un raccord aval (81) situé au niveau du col (8b). Figure pour l’abrégé : Fig 3The invention relates to a system for regulating the temperature of a cryogenic fluid, comprising a pipe (1) for circulating the cryogenic fluid (A), comprising a main branch (12) in which a part (A2) of the cryogenic fluid circulates at an initial temperature (Ti) and a bypass branch (11) in which another part (A1) of the cryogenic fluid is cooled to a final temperature (Tf) lower than the initial temperature (Ti), so as to form a mixture of the said parts (A1, A2) of the cryogenic fluid at a temperature (Tm) comprised between the final temperature (Tf) and the initial temperature (Ti), the said system being characterized in that the main branch (12) comprises a pipe (8 ) successively comprising a converging part (8a), a neck (8b) of section smaller than that of the pipe (1) and a diverging part (8c) and in that the bypass branch (11) is connected to the said pipe ( 8) by an upstream connection (80) if killed upstream of the converging part (8a) and by a downstream connection (81) located at the neck (8b).
