In other words, in the prior art, a fan as a noise source is installed on the discharge side of the ventilation path. Therefore, the sound leaking from the discharge port becomes noise.Therefore, when a large capacity fan is used to improve the cooling function of electronic components, there is a problem that the noise becomes even louder.

し得る。In this case, as described above, the noise source is placed approximately in the middle of the ventilation path, and a plurality of electronic components are placed alternately along the ventilation path on the suction side and the discharge side of the noise source in the ventilation path. Since the structure is configured to bend the flow of air passing through, the ventilation path on the suction side and the discharge side can be made longer than the noise source, and the sound caused by the noise source can be attenuated accordingly. Therefore, noise can be reliably reduced by sound attenuation.
