Abstract

La présente invention ouvre/ferme automatiquement une seconde porte (201) et une première porte (202) d'un second caisson de refroidissement (110) en association avec le mouvement d'une partie de chargement de réactif (103). Une fois que la partie de chargement de réactif (103) a émergé du second caisson de refroidissement (110) et la seconde porte (201) et la première porte (202) sont ouvertes, la seconde porte (201) et la première porte (202) sont verrouillées automatiquement par un trou de serrure de porte (203), un mécanisme de serrure de porte (204), et un cylindre de serrure de porte (206) de façon à ne pas se fermer. Lorsque la partie de chargement de réactif (103) doit être stockée à l'intérieur du second caisson de refroidissement (110), la seconde porte (201) et la première porte (202) sont déverrouillées automatiquement, et la partie de chargement de réactif est stockée à l'intérieur du second caisson de refroidissement (110). La présente invention peut ainsi réduire l'espace d'installation d'un mécanisme, diminuer les éléments du mécanisme, et réduire le risque de dysfonctionnements, sans avoir d'actionneur pour ouvrir/fermer la ou les portes d'un caisson de refroidissement de réactif.
