Abstract
An oil cooler arrangement for internal-combustion engines is described which is used in particular for installation between the engine and an oil filter. The heat exchange space of this oil cooler through which the oil flows is formed as a housing chamber into which a heat exchange body is tightly placed through which the coolant, in particular, water, flows. The heat exchange body includes many parallel pipes, the ends of which are held in the bottoms of two oppositely disposed coolant collecting spaces. This design permits the production of oil coolers without soldering or welding processes. The water flow-through through the parallel pipes is also exactly defined.
