ABSTRACT:
A heat exchanger, especially for the purpose of cooling and filtering motor vehicle engine lubricating oil, has a filter integrated into it, to form a unit which comprises a casing having an outer cylindrical wall symmetrical about an axis, a first end wall and a second end wall. A filter cartridge is contained in a filter compartment within the casing. A first fluid such as engine oil enters a first chamber from whence it passes to the filter compartment. Oil flowing in this first compartment is cooled by heat exchange with a second fluid flowing in a second chamber. The casing contains a cylindrical partition wall extending from the first end wall to the vicinity of the second end wall, to define a communication passage from the first chamber to the filter compartment. Both the first and second chambers are part of a heat exchange compartment containing heat exchange means which separate the two chambers. The first fluid cannot reach the filter until it has passed through the heat exchange means.
