する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic equipment rack, and particularly to an electronic equipment rack having a rack structure that reduces the noise of electronic equipment that requires forced air cooling.

ていない。Conventional electronic device racks have a structure in which sound-absorbing material is attached to the internal side wall of an exhaust duct installed on the air outlet side of a blower that is placed to cool the unit containing the electronic circuit package mounted inside the rack. Other than that, no structure has been adopted to actively reduce noise.

。The conventional electronic device rack described above has a structure in which an exhaust duct covered with sound-absorbing material is placed on the air outlet side of a blower prepared to cool the unit containing the electronic circuit package mounted on the rack. However, with this structure, it is not possible to obtain an average noise attenuation effect down to low frequencies.In addition, the heat generation density of electronic circuit packages has also increased as devices become more integrated and faster, resulting in insufficient blower capacity. In order to solve this problem, installing a large number of large blowers tends to compensate for the lack of capacity and is causing problems such as increased noise.Therefore, it is necessary to reduce the noise without increasing the pressure loss of the blowers. The disadvantage is that it is difficult to speak.

防ぐエアフィルタ８が設けられている。In the electronic device rack shown in FIG. 1, units 1 having electronic circuit packages are mounted in two stages on a frame 6, and blowers 2 are placed above and below the units 1, so that the air flow n from the blowers 2 is uniform. In order to increase cooling efficiency, a rectifying grid 7 made of plates combined in a lattice shape is interposed between the unit 1 and the blower 2, and an air filter 8 is installed at the bottom of the frame 6 to prevent dust from entering the frame. is provided.

るという効果がある。The electronic equipment rack of the present invention has a cavity so that the resonance frequency of the cavity resonance chamber connected to the exhaust duct matches the peak frequency of the noise generated by the blower that cools the unit having the electronic circuit package mounted in the rack. By designing a resonance chamber, we can attenuate the peak of the noise generated by the blower.
By increasing the number of cavity resonance chambers, it is possible to widen the range of resonance frequencies, and this has the effect of providing noise attenuation over a wider range of areas, making it possible to provide a low-noise frame structure that is compatible with high integration. .
