Abstract
A door structure for cabinets according to the invention is configured in a double structure wherein a front door 1 of a cabinet 5 comprises a main surface part 1A, which constitutes the external face, and a metallic meshed member 4, which constitutes the internal face. In the main surface part 1A and the top, bottom, right and left side members 1B through 1E of the door are bored pluralities of ventilation holes 2 and 3, respectively, so that air, entering through lower holes and warmed inside, is discharged through upper holes by such actions as conduction and stirring within the cabinet 5. This structure can enhance both the electromagnetic shielding performance and the cooling effect.
