Abstract

A combined filter and heat exchanger for simultaneous filtering of a first medium and heat transfer between the first medium and a second medium, for example a combined oil filter and cooler for internal combustion engines includes a filter section comprising a hollow, cylindrical filter element (2) arranged co-axially within an outer casing (1) having a cylindrical wall (1a) which extends around the filter element coaxially therewith and in spaced relationship thereto. A heat-exchanger section is arranged in the space between the cylindrical wall (1a) and the filter element (2). The heat-exchanger section includes a cylindrical partition wall (5) subdividing said space into two chambers. The first medium flows first through the inner chamber and is then distributed across the outer surface of the filter element (2), whereas the second medium flows through the outer chamber (7).
