Zusammenfassung:	Nowadays, many demands for the recooling of various media are being placed on the output side of internal combustion engines. The use of hydrodynamic outputs or hydrostatic outputs, but also the use of retarders, requires recooling of the hydraulic oil. However, in the operation of heat pumps and the drives of air conditioning units recooling of condensing and evaporating media is also necessary. The plant operator frequently requires of the motor manufacturer the recooling of various hydraulic circuits, but also of various media, in conjunction simultaneously with a compact design of the heat exchangers. The heat exchanger principle presented by the invention permits a plurality of recooling media to be simultaneously applied by taking account of an optimised overall cooler volume. The heat exchanger is designed as an obliquely divided block consisting of at least two cooling units. Division is performed in such a way that a constant flow resistance prevails in all regions for the medium to be cooled. Provided for the cooling medium in the heat exchanger are turbulence generators which decrease in the direction of flow as a function of the achievable effect (Fig. 1).
