<p><P>PROBLEM TO BE SOLVED: To provide a device which has a plurality of heating elements and a cooling mechanism therefor, and which rapidly and appropriately controls cooling capacity distribution according to the heating situations of respective heating elements. <P>SOLUTION: A disk array device 1 is provided with: a plurality of HDD units 3 each having a hard disk drive (HDD) 4 as the heating element; a ventilation mechanism 6 for cooling the HDD 4 by ventilation; and air quantity regulating mechanisms 5 for regulating the flow rate of air for cooling the respective HDDs 4. If the HDD 4 is at a low temperature, the air quantity regulating mechanism 5 takes such a shape as to close the channel of air, and if the HDD 4 is at a high temperature, its heat is directly conducted to the air quantity regulating mechanism 5 via a conductor, and the air quantity regulating mechanism 5 is deformed so as to open the channel of air by the heat. Thereby, according to the heating situations of the plurality of HDDs 4, the air flow rate to the respective HDDs 4 can be regulated. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
