Patent ID: 7300485

Claim:
An apparatus for trapping contaminants and circulating air within a cavity of an electronic device, said apparatus comprising: a housing having a centrally disposed longitudinal axis and including a plurality of sides sized and shaped for being removably engageable with the electronic device, said housing comprising a plurality of passageways oppositely disposed from the axis for channeling air through first and second directions; at least one fan situated along one said sides for cooperating with said passageways during operating conditions wherein air having a first contamination level is channeled into said housing along the first direction and air having a second contamination level is channeled outwardly and away from said housing along the second direction; a filter bifurcating said passageways and extending substantially parallel to the axis wherein the contaminants are trapped upstream one said passageways and so that the second contamination level is less than the first contamination level, said air having the second contamination level exiting said housing for cooling the electronic device; and a power supply source electrically coupled to said fans.
