<p><P>PROBLEM TO BE SOLVED: To efficiently eliminate heat generated inside an information processor and to attenuate noise due to passage of discharge air flow caused by a cooling fan for improving silence properties. <P>SOLUTION: The extension device is provided with a cooling means, which is a second cooling fan arranged on the outside surface corresponding to a heat conductive member in integration with the information processor for generating discharge air flow to be discharged to the outside for cooling heat transmitted via the heat conductive member, an inlet port arranged on the outside surface corresponding to an outlet port in integration with the information processor for introducing discharge air flow discharged from the information processor by a first cooling fan, a first silencing means attenuating noise generated by passage of the discharge air flow introduced from the inlet port, a second silencing means attenuating noise generated by passage of the discharge air flow generated by the second cooling fan, and the outlet port for discharging the discharge air flow. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
