Abstract (en)

[origin: DE19519740A1] The proposal is for a heat exchanger, especially an oil cooler for internal combustion engines. It consists of a plurality of mutually parallel tubes to convey the heat exchange medium and blade-like heat exchange elements (11) arranged perpendicularly to the tubes. The heat exchange elements (11) are firmly secured to the tubes and also bent at the outer edges and are superimposed in the manner of scales. The medium to be cooled is fed in via pipes arranged perpendicularly to the heat exchange elements. Said pipes open into a distributor plate (13) having a liquid inlet (15) and a liquid outlet (20). The inlet (21) and/or the outlet (22) for the coolant is also fitted in the distributor plate (13).
