Device for generating air curtain in opening for accessing isothermal case of refrigerated vehicle, has distribution structure extended from parallel to side of frame of opening, where structure presents over in length direction at tube

摘要

The device has a delivering unit (20) for delivering air flow from an outer side of an enclosure. A distribution structure is longitudinally extended from parallel to a side of a door frame of an opening, where the structure presents over in a length direction at a tube for diffusing the air in the opening. The distribution structure is connected with the delivering unit. A diving unit divides the flow delivered into three currents. A channel (32) is placed between an insulating wall (7a) and a cover panel.
