Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing noise and heat generated by electronic equipment pose challenges for cooling and maintenance, as traditional sealed enclosures trap heat and noise, leading to equipment failure, while dedicated rooms are expensive and inefficient.
Innovation Solution
A ventilated enclosure system with noise-absorbing acoustic chambers and baffles, along with intake and exhaust modules, that allows for airflow while reducing noise transmission through cable egress ports, utilizing materials with noise-absorbing properties to manage heat and noise effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If equipment is placed in sealed enclosures to trap noise, then noise reduction is improved, but heat accumulates leading to equipment failure
Solution Approach 1:
The enclosure is divided into multiple acoustic chambers separated by baffles, creating segmented pathways that trap noise internally while allowing heat to be carried away by airflow through the chambers
Solution Approach 2:
Acoustic chambers filled with noise-absorbing material serve as intermediaries between the equipment and the external environment, absorbing noise energy while permitting thermal energy to pass through via convection currents
2Temperature
If ventilation openings are added to enclosures to remove heat, then heat removal is improved, but noise escapes the enclosure
Solution Approach 1:
Acoustic chambers are nested within the enclosure structure, with baffles creating nested pathways that guide airflow for heat removal while trapping noise within the nested chamber configuration
Solution Approach 2:
The airflow necessary for heat removal is converted into a beneficial force that carries noise deep into acoustic chambers where it is absorbed, transforming the potential harm of noise escape into enhanced noise trapping
3Object-generated harmful factors
If dedicated electronic equipment rooms are created to reduce noise, then noise abatement is improved, but cost and space requirements increase
Solution Approach 1:
Multiple acoustic chambers and noise control features are merged into a single integrated enclosure unit, combining the functions of noise trapping, heat removal, and equipment housing into one compact structure
Solution Approach 2:
The enclosure uses thin baffle structures and acoustic chamber walls that provide effective noise separation without requiring the mass and complexity of dedicated room constructions

AI summary
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 chambers can contain baffles that 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.
