Abstract
In order to achieve a high cooling power while avoiding troublesome cold air flows, a chamber (2) is sealed, from the room to be cooled, by a thin cooling wall (1) of powder-coated steel with micro-holes which are arranged in a square 5 mm grid and have a diameter of 0.5 mm and whose free cross-section is consequently less than 1%. An antechamber (4) which is connected to the chamber (2) through a partition (3) by means of a distributor nozzle (17) and has air connections for connection to an air supply or an adjacent air-cooling element is arranged above the chamber (2). The cool air is introduced into the chamber (2) via the distributor nozzle (17) in such a way that it passes with high turbulence along the inside of the cooling wall (1). An air-cooling arrangement consists of rows, arranged side by side, of air-cooling elements whose antechambers (4) are connected by connecting nipples which each project into connecting orifices (10) of adjacent air-cooling elements.
