ABSTRACT OF THE DISCLOSURE An air-cooled heat exchanger for cooling industrial liquids, in particular liquids including solid particles and/or components which are inclined to precipitate or be deposited on cooling below the saturation temperature, com- prises one or more bundles of fin tubes. Fan means are as- sociated with the fin tubes for externally applying cooling air to the same. The bundles are in relation to the liquid flow to be cooled composed of preferably horizontally a- ligned, mutually intercommunicating fin tubes arranged in series, spaced apart and parallel to one another in two dimensions normal to the tube axes. The fin tubes which within each bundle are constructionally arranged in series of parallel tubes one behind the other in the direction of air flow, are so connected up that they are subdivided in- to at least two groups separately connected to the liquid flow to be cooled, all fin tubes associated with any one particular group being interconnected in series by tube bends or equivalent means provided at their respective ends. The fin tubes associated with the individual groups are arranged within each series assembly in alternating sequence in accordance with the number of groups. The flow path is prescribed by the apparatus for the liquid to be cooled through the fin tubes by their being interconnected groupwise throughout in meandering pattern in ever alter- nating direction in a cross-countercurrent pattern in re- lation to the cooling application, both within each series of tubes as well as in respect of the various series of tubes arranged in succession parallel to one another, viewed in the direction of the airflow.
