Claim 0:
1. A cooler, comprising:
individual cooling elements of stacked construction having ducts extending in parallel to one another, each of the ducts delimiting a flow chamber being capable of a first throughflow of a liquid medium to be cooled and being free of obstacles permitting a laminar flow of the liquid medium through each of the ducts in a liquid throughflow direction, each of the flow chambers having a rectangular free throughflow cross section solely delimited by peripheral duct walls in a direction transverse to the liquid throughflow direction, the duct walls having a duct wall thickness;
at least two layers of individual fin rows of meandering fins extending between each adjacent pair of the ducts, being capable of a throughflow of air jointly and delimiting a second flow chamber, each of the fins having a fin height at least as large as the free throughflow cross section of the flow chambers of the ducts arranged adjacent thereto and having a fin wall thickness equal to the duct wall thickness, each of the fin rows having the fins being arranged in succession and being offset from each other in the liquid throughflow direction in parallel in each of the layers;
two media-conveying main struts, the ducts and the fin rows of the fins extending between the main struts and spanning a rectangular front cooler surface, the flow chambers of the ducts being connected in fluid communication with interiors of the main struts; and
a partition wall separating the two layers, the partition wall and the two layers and extending in horizontal planes.
