STRAINER WALL STRUCTURE INCLUDING PLURALITY OF CURVED PORTIONS, METHOD FOR MANUFACTURING STRAINER WALL STRUCTURE, AND METHOD FOR FILTERING USING STRAINER WALL STRUCTURE

摘要

The present invention aims to provide a strainer wall structure including a plurality of curved portions, a method for manufacturing the strainer wall structure, and to a method for filtering using the strainer wall structure, which has a substantially larger filtering area for the same length and width, can substantially reduce foreign substances that cover an induction surface and flow-through resistance from the foreign substances, and can accordingly reduce the decrease in the pressure of a coolant before and after flowing through. To this end, the strainer wall structure having the plurality of curved portions of the present invention, which is provided with an inlet side for receiving the coolant and a discharge side for discharging the coolant that has been filtered, comprises: a body provided with the inlet side and the discharge side facing the direction of an open portion; and a first filtering plate, which is inserted inside the body, and has the plurality of curved portions that are formed by bending a first punched plate, provided with a plurality of filtering holes, in the opposite direction from the previous curved portion with a predetermined distance between the curved portions.
