Abstract

La présente invention concerne un bâti de serveur, qui est conçu dans une structure hermétique, empêchant ainsi toute entrée de poussière, qui assure une fonction de température constante/humidité constante permettant de régler à une température constante l'intérieur du bâti de serveur tout le temps par l'intermédiaire d'une double fonction de commande, qui combine une commande de refroidissement d'un dispositif à cycle de réfrigérant et une commande de chauffage d'un dispositif de chauffage, qui assure une fonction de protection d'urgence permettant une protection contre un échauffement provoqué par une température anormalement élevée ou similaire, et qui assure des fonctions de détection et d'extinction d'incendie. La présente invention concerne ainsi un bâti (10) de serveur comprenant une caisse (1) de bâti, sur laquelle est installé un cadre de montage en vue de monter un équipement d'exploitation (S) ; une porte (2) accouplée à la surface avant de la caisse (1) de bâti de sorte à pouvoir s'ouvrir/se fermer ; et un module (3) de température constante/humidité constante permettant de maintenir l'intérieur de la caisse (1) de bâti à une température constante et à une humidité constante. Ledit bâti (10) de serveur est essentiellement caractérisé en ce qu'il comprend : un module (3) de température constante/humidité constante comprenant un conduit de circulation d'air interne (4) et un conduit de circulation d'air externe (5) ; un dispositif de protection d'urgence comprenant un clapet d'échappement (4), qui évacue l'air depuis l'intérieur de la caisse (1) de bâti vers l'extérieur lors d'une situation d'urgence, et un clapet d'admission (7) permettant d'introduire de l'air depuis l'extérieur vers l'intérieur ; et un dispositif d'extinction (4) d'incendie comprenant un capteur (5) permettant de détecter un incendie à l'intérieur de la caisse (1) de bâti et un extincteur (6) d'incendie destiné à pulvériser un produit chimique extincteur et à éteindre ainsi l'incendie.
