Abstract:
An information processing apparatus comprising:a circuit board housed in a housing; a duct installed to the circuit board, said duct forming a cooling air passage in the housing; at least one cooling fan for feeding cooling air to the cooling air passage; first and second heat generating components mounted on the circuit board and located in the cooling air passage, said first and second heat generating components being arranged such that said first and second heat generating components are displaced from each other in a flowing direction of the cooling air in the cooling air passage and displaced from each other in a direction transverse to the flowing direction of the cooling air in the cooling air passage; and heat sinks individually and thermally connected to the first and second heat generating components, respectively, the heat sinks having a plurality of radiation fins exposed to the cooling air passage, said radiation fins extending further in the flowing direction of the cooling air in the cooling air passage than in the transverse direction and being spaced from one another in the direction transverse to the flowing direction of the cooling air in the cooling air passage.
