1. A disk array apparatus, comprising:
- a plurality of disk modules, in each of which a disk for recording information is accommodated in a cabinet having a plane;
a plurality of disk boxes, each of which is configured by including an inlet ventilating surface and an exhaust ventilating surface arranged parallel to said inlet surface, and in each of which said plurality of disk modules are accommodated in line along a horizontal direction such that said planes are orthogonal to said inlet surfaces;
a rack, in which a disk unit is formed by arranging two of said disk boxes along the horizontal direction such that exhaust surfaces of said disk boxes face each other in parallel, and in which a plurality of said disk units are accommodated in a stacking manner along a vertical direction, and of which surfaces facing said inlet surfaces of said disk boxes are capable of ventilation; and
an exhaust fan which is arranged in said rack and allows air to pass through said inlet and said exhaust surfaces of said disk boxes and to flow through a draft passage formed parallel to said exhaust surfaces of said disk boxes in said rack to an outside of said rack,wherein a heat radiation member is provided on each of said planes of said disk modules;
wherein said disk boxes include exhaust ports formed on said exhaust surfaces, and ends of said heat radiation members of said disk modules protrude from said exhaust ports to said draft passage.

Abstract
A disk module with a disk for recording information and a controller for controlling operation of the disk in a cabinet, is formed by providing a heat radiation member on at least one of two side faces of the cabinet. The disk array apparatus includes a plurality of disk boxes, each of which accommodates a plurality of the disk modules therein and has an inlet surface on one end side and an exhaust surface on the other end side; a rack which can accommodate the disk boxes therein in a stacking manner and of which surfaces facing the inlet surfaces of the boxes are capable of ventilation; and an exhaust fan arranged in the rack. The heat radiation member is provided on at least one of the two side faces of the cabinet for each disk module, which are parallel to the recording surface of the disk.
