VENTILATION PANEL FOR ELECTRONIC DEVICE AND METHOD OF MAKING SAME Russian patent published in 2015 - IPC G12B15/04 G12B17/00 H05K7/20 H05K9/00 

FIELD: radio engineering, communication.

SUBSTANCE: ventilation panel of an electronic device, placed in a housing, consists of a frame and a ventilation plate built into the frame, made of an electroconductive metal or alloy, having a field of ventilation openings, the greatest dimension of each of which provides a given level of shielding the maximum frequency of the electromagnetic radiation of the electronic device, and means of mounting the frame to the housing of the electronic device, which provide electrical contact. The frame of the ventilation panel has at least one recess, the dimensions and shape of which correspond to the dimensions and shape of the ventilation plate, and the depth is greater than 0.5 times the thickness of the ventilation plate; the ventilation plate has a field of openings on its entire area, the maximum dimension of which is selected in the range of 2.0…6.0 mm, and elements for mounting to the frame in the recess, which provide electrical contact. The method of making a ventilation panel includes the following: cutting the ventilation plate from a given type of a perforated sheet of electroconductive material with openings, the greatest dimension of which is in a range which provides a given level of shielding electromagnetic radiation of the electronic device; connecting the plate with the frame using screws or electroconductive adhesive or by welding or soldering.

EFFECT: simple design of the ventilation unit owing to low labour input in making the ventilation panel with high effectiveness of shielding, simple method of making ventilation plates.
