<p>A heat exchanger element, particularly for heat exchangers for the dust-free cooling of control cabinets or such like, has a block-shaped package, made up of essentially plate-shaped individual parts, in which are constructed first and second channels (5,6), arranged side by side, which are separated from one another by heat-exchanging separating walls and which are connected to inlet and outlet openings (7,8; 9,10), located in each case on different sides of the package, through which flows the medium which supplies and extracts the heat. In order to achieve a simple, cost-effective manufacturing capability, the arrangement is designed such that vertical laminates (4), forming the separating walls, are arranged between two flat profiles (1,2), which form the upper and lower sides of the package and have formed, continuous slot- or wave-shaped depressions (3), which laminates are inserted close together on the edge in associated depressions (3) in the two profiles, and are held therein. In this arrangement, at least one of the flat profiles has inlet and/or outlet openings for the perforations forming the first or second channels, whose associated channels are sealed on at least one end face by sealing elements (13,14) placed thereon. <IMAGE></p> |
