Abstract

Unité de refroidissement du type boîte, qui est utilisée pour résoudre les problèmes techniques selon lesquels un mode de montage de condenseur d'une unité de refroidissement du type boîte classique conduit à un entretien et à un nettoyage peu pratiques, et est susceptible de provoquer une réduction de l'efficacité d'échange de chaleur. Un ensemble condenseur supérieur selon la présente invention comprend un cadre de surface supérieure, un module condenseur et un ventilateur, le cadre de surface supérieure étant monté sur la surface supérieure d'un corps de boîte, le module condenseur étant monté sur le cadre de surface supérieure, le ventilateur étant monté au niveau du fond du cadre de surface supérieure, un côté de sortie d'air du ventilateur faisant face vers le haut, et le module condenseur étant situé sur le côté sortie d'air du ventilateur. Dans le présent mode de réalisation, l'ensemble condenseur supérieur est agencé sur la surface supérieure du corps de boîte, et le module condenseur est monté sur le cadre de surface supérieure de manière à être situé sur le côté d'évacuation d'air du ventilateur. Lorsque la surface du module condenseur devient sale et bloquée après une utilisation à long terme et affecte ainsi l'efficacité d'échange de chaleur, la surface du module condenseur peut être rincée directement avec un pistolet de pulvérisation, ce qui permet d'assurer que l'efficacité d'échange de chaleur du module condenseur ne sera pas affectée par la saleté et le blocage de surface.
