Zusammenfassung: | Cooling unit which consists of at least two horizontal grids placed one below the other. The grids 1 consist of dispersion members 2 lying parallel beside each other and having an elongate cross-section in the shape of a quadrilateral or of a trapezium as well as transverse vertical stiffening members 3, the cross-section of the transverse stiffening members having the shape of an elongate drop with a horizontal axis and the broad part of the drop-shaped cross-section being oriented in the direction of the agent A flowing horizontally; the grids 1 are joined in the form of a unit assembly by means of the spacer legs 4 which may be fitted into each other; and the vertical dimension b of the vertical dispersion members 2 is advantageously between 25 and 50% of the vertical spacing e of the grids 1 placed one below the other. Application to a cooling unit having a small resistance to the horizontal flow of air.
