Storage box for electronic apparatus

摘要

A box-shaped enclosure for electronic apparatus includes a deadening wall or walls defining a storage space 32 between first and second planes 13, 15. The storage space is open at the first and preferably the second plane. A deadening wall member 26 extends along the first plane, forming the inner side of a door 14. The door is in the form of an auxiliary box-shaped enclosure connected to the main box-shaped enclosure so as to close the first plane. The auxiliary box-shaped enclosure defines an auxiliary space 47 isolated from the storage space 32 with a deadening wall member. The storage space is connected to the fresh air through a ventilation opening 22, the auxiliary space 47 and an inner opening 28. The outer ventilation opening and the inner through-opening are preferably elongate and parallel but offset in the plane of the door, either horizontally or vertically, to give the air a convoluted path. Fans 31 are arranged along the inner opening 28. The layout and the deadening wall or walls of the box-shaped enclosure and the deadening wall member serve to prevent the leakage of the operating sound. Doors 14, 16 can be fitted to the front and back of the main enclosure, or a single door can be subdivided, with one of the exterior vents 24 connected via a passage 85 to the rear of the interior.
