Abstract
An air filter for electrical equipment includes metallic filter media including a first outer layer, an opposing second outer layer, and at least one inner layer disposed between the first outer layer and the opposing second outer layer, and a frame disposed along a perimeter edge of the filter media configured to retain the filter media.
Claims20
An air filter for electrical equipment, the air filter comprising:
- metallic filter media including a first outer layer, an opposing second outer layer, and at least one inner layer disposed between the first outer layer and the opposing second outer layer;
- and
- a frame disposed along a perimeter edge of the filter media configured to retain the filter media.
A networking device, comprising:
- an enclosure;
- electrical components;
- and
- at least one filtration assembly removably disposed within the enclosure, each of the at least one filtration assembly includes:
- an inlet face;
- a back opposite the inlet face;
- a first side extending from a first edge of the inlet face toward the back at a non-right angle oriented toward a centerline;
- a second side extending from a second edge opposite the first edge of the inlet face toward the back toward the back at a non-right angle oriented toward a centerline;
- and
- a filter removably disposed along the first side or the second side.
7 more elements
A filtration method in electrical equipment comprising:
- providing at least one filter assembly insertably removable within a body of the electrical equipment;
- circulating air to flow through an inlet of the at least one filter assembly arranged at an exterior face of the body and over a filter media of the at least one filter assembly;
- redirecting and smoothing the air flow through the filter media via a tapered plenum formed within the at least one filter assembly;
- filtering air as it passes through the filter media;
- passing filtered air over internal electrical components housed within a chassis of the electrical equipment;
- dissipating heat radiating from the electrical components as the air flows across the electrical components;
- and
- expelling heated air out of the body of the electrical equipment.
