VENTILATING WINDOW FRAME FOR ELECTROMAGNETIC SHIELDING

摘要

PROBLEM TO BE SOLVED: To make shielding performance coexist with ventilation performance. ;SOLUTION: The ventilating window frame 5 is disposed so as to communicate the inside and outside of an electromagnetic shielding room. The ventilating window frame consists of a bent passage 10 formed in a frame body 8, an outside-air intake 6 formed on the outdoor side X of the frame body 8, the outlet 7 of the outside air formed on the indoor side Y of the frame body 8 and a wave absorber 12 lined around the bent passage at that time. A conductive shutter 11 opening and closing the bent passage may also be arranged into the bent passage 10.;COPYRIGHT: (C)1999,JPO
