Abstract
A strainer wall structure includes curved sections, a method of manufacturing the same, and a filtering method using the strainer wall structure to provide a substantially larger effective filtering area in the same length and width, substantially reducing foreign substances covering a suction surface and flow resistance of the foreign substances, and reducing pressure drop at a cooling water pass corresponding thereto. The strainer wall structure includes an inlet side through which cooling water is introduced and an outlet side through which the filtered cooling water is discharged, includes a body having openings in directions of the inlet side and the outlet side, and a first filter plate inserted into the body and including curved sections formed by alternately bending a first punched plate having filtering holes in opposite directions and at a predetermined interval.
