Disk module, and disk array apparatus

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 heat radiation plates protruding from said exhaust ports to said draft passage, and
• wherein said heat radiation plates and said heat radiation members of said disk modules are brought into contact with each other.
