Abstract

L'invention concerne un ensemble armoire et un échangeur de chaleur. L'échangeur de chaleur comprend un ensemble boîtier et une rangée de tuyaux de radiateur. La rangée de tuyaux de radiateur est formée par une pluralité de tuyaux de radiateur agencés côte à côte et espacés. Les conduites de chaque tuyau de radiateur forment des premiers conduits d'air de circulation. L'ensemble boîtier comprend une plaque latérale avant et une plaque latérale arrière respectivement disposées sur une surface latérale avant et une surface latérale arrière de la rangée de tuyaux de radiateur. Un espace est formé entre deux tuyaux de radiateur adjacents dans la rangée de tuyaux de radiateur. La plaque latérale avant et la plaque latérale arrière entourent chaque espace pour former des seconds conduits d'air de circulation. L'un parmi le premier conduit d'air de circulation et le second conduit d'air de circulation est un conduit d'air de circulation externe, et l'autre est un conduit d'air de circulation interne. La plaque latérale arrière est positionnée à l'extérieur du corps d'armoire. Par comparaison avec l'état de la technique, le flux d'air dans les conduits d'air de circulation interne de l'échangeur de chaleur actuel peut rayonner directement de la chaleur vers l'extérieur de l'armoire au moyen de la plaque latérale arrière ou de la plaque latérale arrière et de la paroi de tuyau. Par comparaison avec une armoire classique, l'efficacité de rayonnement thermique du flux d'air dans les conduits d'air de circulation interne est efficacement améliorée, et l'efficacité de dissipation de chaleur d'un dispositif électronique dans l'armoire est améliorée.
