Abstract
A system and method are disclosed for enclosing electronic equipment in a noiseproofed and ventilated enclosure. This includes supplying air to an enclosure and removing air from the enclosure through acoustic chambers attached to the enclosure. The acoustic chambers can be constructed of materials or be treated with materials that have noise-absorbing or noise-abating properties. In addition, the acoustic chamber for exhausting air from the enclosure can contain baffles that help to prevent noise that has entered the acoustic chamber from leaving the chamber. And, the system and method can use a cable egress port that allows cables and wiring to pass through the egress port while blocking the transmission of noise through the egress port.
Claims20
A housing for abating noise generated from within the housing, the housing comprising:
- an intake inlet in fluid communication with an intake internal chamber for receiving outside air therethrough;
- an intake outlet for exhausting air from the intake internal chamber into a housing structure;
- the housing structure having an air ingress opening in fluid communication with the intake outlet of the intake internal chamber, and the housing structure having an air egress opening for passing air outside the housing structure;
- noise-abating material disposed on at least a portion of internal walls of the intake internal chamber;
- and
- a cable egress port comprising:
- a port structure adapted to be received at a port opening in the housing structure, the port structure including an open back and top, and a removable cover;
- the removable cover being capable of being fixed to the port structure to accommodate a plurality of different sized cables;
- and
- noise-abating material being disposed inside the port structure and on the internal surface of the removable cover such that when the cover is fixed to the port structure, the noise-abating material disposed on the internal surface of the removable cover mates with the noise-abating material inside the port structure to substantially seal at least one cable passing through the port structure into the housing structure such that noise emanating from the housing structure is abated from exiting through the port structure.
