ABSTRACT:
A thermal capacitor cools servers when an active cooling system fails. The thermal capacitor includes cold insulation passages, fans, temperature sensors, and a control unit. The cold insulation passages each have a plurality of air flow channels obtained by dividing the air flow path into a plurality of air flow paths with different air flow path cross-sectional areas. The fan is mounted in each air flow path and the fan controls the air flow of each air flow channel. A temperature sensor is mounted in each outlet of the cold insulation passages. When a detected temperature exceeds a predetermined temperature, the control unit controls air flow so that the ratio of air flow by air flow passage with larger air flow path diameter to overall air flow of all air flow channel increases.
