DEVICE FOR STRAINER FILTERING INCLUDING FILTERING TUBE

摘要

The present invention aims to provide a device for strainer filtering including a filtering tube, 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 which can accordingly reduce the decrease in the pressure of a coolant before and after flowing through. To this end, in the device for strainer filtering including the filtering tube of the present invention, having at least one inlet side for receiving the coolant and at least one discharge side for discharging the filtered coolant, comprises: the filtering tube comprising a hollow tube which is formed by bending a punched plate having a plurality of filtering holes; an upper portion plate having a first groove on the lower surface thereof so as to couple the upper end of the filtering tube to an inlet portion, and having an inlet portion for receiving the coolant; and a lower portion plate having a drilled hole to which the lower end of the filter tube is coupled, wherein the filtered coolant inside the filtering tube flows into the drilled hole and is discharged from the discharge side.
