Oil cooler mounting structure and oil cooler mounting method

摘要

An oil cooler mounting structure includes: a heat exchanger tank (10) that is made of aluminium and has an oil cooler mounting hole (12) in a wall surface thereof; an oil cooler (20) that is made of aluminium, has an insertion hole for an oil introducing/discharging pipe formed in a seat portion, and is mounted inside the heat exchanger tank with a plurality of projecting pieces (25) erected around the circumference of the insertion hole; a patch (30) that is made of an aluminum-containing brazing filler metal and is arranged on the outer circumference of the projecting pieces (25) of the oil cooler; and an oil introducing/discharging pipe (40) that is inserted into the insertion hole formed in the seat portion of the oil cooler; whereby the oil cooler (20) is mounted inside the heat exchanger tank (10) by having the plurality of projecting pieces (25) of the oil cooler project outside through the oil cooler mounting hole (12), by setting the patch (30) around the outer circumference of the plurality of projecting pieces (25), and by bending the plurality of projecting pieces (25) toward the patch (30).
