ABSTRACT:
An air-cooled information processing apparatus has a plurality of units and a casing accommodating the units. At least one cooling air supply section and at least one cooling air discharge section are provided in the casing, for supplying cooling air into the apparatus and for discharging the air therefrom. A partition member divides the space inside the casing so as to define at least two cooling air flow channels between the cooling air supply section and the cooling air discharge section. At least one main fan unit is disposed in each of the cooling air flow channels. The cooling air flow channels include at least one first cooling air flow channel in which at least two units from among the plurality of units are disposed in parallel with each other with respect to the direction of flow of cooling air, and at least one second cooling air flow channel in which at least two units from among the plurality of units are arranged in series to each other along the flow of cooling air. This cooling arrangement ensures optimum cooling for different types of units in the apparatus, without being accompanied by rise in the noise level, rate of discharge of air, power consumption and production cost.
