ABSTRACT:
The side wall (8) of the cylindrical casing (1) of an oil filter containing a filtering element (2) consists of a heat exchanger defining two entwined circuits one (6, 14) of which is intended for the oil before its filtration and the other (9, 15) of which is intended for a cooling liquid. Each circuit extends helically and is delimited by a cylindrical sleeve (11, 12) and by a groove (14, 15) hollowed out of an intermediate partition (13).
