A mechanical draft cooling or condensing plant for air cooling or condensing a medium conducted in a closed circuit, particularly a plant of major cooling capacity, in which mechanical draft cooling air enters the plant substantially in the horizontal direction through vertical walls in the plant and the medium to be cooled flows through plate-shaped cooling elements composed of a plurality of finned tubes, the cooling elements extending in vertical planes and, together with bearing and support means, form one or more of the substantially vertical walls which are zigzag-shaped in plan, and wherein, viewed in the direction of flow of the cooling air in front of and/or behind the walls a large number of extractor and blower fans are disposed in uniform distribution over the entire surface of the wall or walls in immediate proximity with the cooling elements, the fans being placed so that their blades revolve in vertical planes.
