Abstract: Desublimer for the recovery of sublimed products from reaction gases, consisting of a closed housing for the passage of the reaction gas and a plurality of horizontally mounted rows of finned tubes for the passage of the heating or cooling medium, in which a perforated slider is mounted on each finned tube to allow adjacent finned tubes to bear loosely against each other, the stack of superposed sliders associated with each finned tube being loosely supported on a girder securely attached to the housing.

Abstract translation: Desublimer用于从反应气体中回收升华产物，包括用于反应气体通过的封闭壳体和多个水平安装的翅片管排，用于通过加热或冷却介质，其中安装有多孔滑块 在每个翅片管上允许相邻的翅片管彼此松散地相对承载，与每个翅片管相关联的叠置的滑块被松散地支撑在牢固地附接到壳体的梁上。
