Abstract

<P>PROBLEM TO BE SOLVED: To provide a duct in which less dusts are piled up in an intake port and a rack having the duct. <P>SOLUTION: The duct 20 comprises a first opening 21 provided at a position apart from a floor at an opposite side to the rack 10, an intake duct having a second opening coupled to an intake fan 12, a third opening coupled with an exhaust port 13 of the rack, and an exhaust duct having a fourth opening 22 opened upward and disposed above the third opening. The intake port 21 is separated apart from the floor so as to reduce an amount of entering dusts or an amount of the piled up dust in the port 21. The exhaust duct is opened upward thereby preventing an exhaust air from entering again and improving exhaust efficiency by a stack effect. Further, since the fan 12 is covered with the duct 20, a noise is reduced. <P>COPYRIGHT: (C)2003,JPO

In the conventional rack as described above, since the intake position of air is near the floor surface, it is easy to suck dust from the intake port, and dust is likely to collect at the intake port. There was a point. Therefore, there is a problem in that dust accumulates in the rack and causes a failure of the device, or the amount of air taken in due to the dust accumulated in the intake port decreases, and the cooling effect decreases. Also,
There is also a problem that the fan is installed in the opening of the panel, which causes a lot of noise. An object of the present invention is to solve the above-mentioned problems of the conventional technology, and to provide a duct that is less likely to collect dust in the intake port and that reduces fan noise, and a rack including the duct.
