<p>A filter and heat exchanger device comprises a substantially cylindrical housing (11) accommodating a tubular heat exchanger body (31) having fins (35) on the outer side thereof and an axial through passageway (32, 33) communicating with secondary-liquid inlet and outlet ports (19, 20). A heat exchanger compartment (26) inside a cylindrical partition (28) in the housing (11) accommodates the heat exchanger body (31) and a filter compartment (27) outside the partition accommodates a filter body (30). The two compartments (26, 27) communicate with one another and form successive sections of a primary-liquid flow path extending between primary-liquid inlet and outlet ports (17, 18). An elongate opening in the partition (28) is substantially coextensive with the heat exchanger body (31) and defines a flow passage (29) which interconnects the heat exchanger and filter compartments (26, 27). The heat exchanger body (31) is positioned in the heat exchanger compartment (26) and defines together with the inner side of the partition (28) circumferentially extending channels between the fins (35) of the heat exchanger body (31). An axially extending channel (36) formed in the cylindrical partition (28) diametrically opposite to the flow passage (29) is substantially coextensive with and open towards the heat exchanger body (31) and communicates with the primary-liquid outlet port (18).</p> |
