Cover for electronic equipment including at least two movable metal panel elements. The upper cover is configured to be pivotable on a support axis with respect to the main body. The second electrode patterns are opposite to the first electrode patterns, respectively, and the second electrode patterns and the first electrode patterns are alternately arranged. Baffles in the transverse dividing member quench the ionized gases and provide fluid communication between exhaust channels formed between the segregator fins of the first portion, and gas ducts disposed between the segregator fins of the second portion.
