Abstract
There is provided an exemplary dust trap and a system and method for filtering air. An exemplary dust trap comprises a housing with an air intake. The exemplary dust trap also comprises a plurality of screens disposed within the housing downstream of the air intake and configured to pass air and capture airborne contaminants, wherein the screens are configured to provide an unscreened air passage between the screens.
Claims13
A dust trap, comprising:
- a housing comprising an air intake;
- and
- a plurality of screens disposed within the housing downstream of the air intake and configured to pass air and capture airborne contaminants, wherein the screens are configured to provide an unscreened air passage between the screens, and wherein the unscreened air passage comprises a series of slanted gaps located between an internal surface of the housing and alternating edges of each of the screens.
A system for filtering air, comprising:
- a fan configured to provide a flow of cooling air through an air channel;
- a heatsink disposed in the air channel and configured to receive the flow of cooling air;
- and
- a dust trap comprising a plurality of mesh baffles disposed inside the air channel, wherein each of the plurality of mesh baffles spans less than the full cross-sectional area of the air channel and are configured to provide an unscreened air passage, and wherein the plurality of mesh baffles are slanted to form the unscreened air passage toward an air intake of the air channel.

A method for filtering air, comprising:
- receiving a flow of air;
- passing the air through a plurality of baffles if the plurality' of baffles is substantially unblocked by contaminants;
- and
- passing the air through a winding path between the plurality of baffles if the plurality of baffles is substantially blocked by the contaminants, and wherein the winding path comprises a series of slanted gaps located between an internal surface of a housing and alternating edges of each of the baffles.
