  "abstract": "An embodiment an apparatus, including: a housing that permits airflow there-through; an air permeable filter disposed in the housing; where the air permeable filter is angled such that it does not sit in a horizontal plane across the housing; and an attachment mechanism for securing the housing to an enclosure that houses heat generating electronics. Other embodiments are described and claimed.",
  "claims": [
    "1. An apparatus, comprising: a housing that permits airflow there-through; a filter holder that attaches to the housing and has a predetermined shape selected from angled and arced; an air permeable filter disposed in the filter holder; wherein the predetermined shape of the filter holder, in a closed state, shapes the air permeable filter to be angled such that it does not sit in a horizontal plane across the housing; and an attachment mechanism for securing the housing to an enclosure that houses heat generating electronics a second attachment mechanism for securing the filter holder to the housing; wherein the second attachment mechanism for securing the filter holder to the housing comprises a hinge mechanism that permits one side of the filter holder to release from the housing and another side of the filter holder to be attached to the housing via the hinge mechanism.",
    "2. The apparatus of claim 1, wherein the air permeable filter is shaped such that it does not transit across an opening formed in the housing in a straight line.",
    "3. The apparatus of claim 1, wherein the air permeable filter is angled 45 degrees with respect to a horizontal plane across the housing.",
    "4. The apparatus of claim 2, wherein the air permeable filter is arc shaped.",
    "5. The apparatus of claim 1, wherein the attachment mechanism for securing the housing to the enclosure that houses heat generating electronics attaches the housing to a filtered fan that is attached to the enclosure.",
    "6. The apparatus of claim 1, wherein the attachment mechanism for securing the housing to the enclosure that houses heat generating electronics attaches the housing directly to the enclosure.",
    "7. The apparatus of claim 1, further comprising a blower assembly disposed in the housing.",
    "8. An apparatus, comprising: a housing that permits airflow there-through; a filter holder that attaches to the housing and has a predetermined shape selected from angled and arced; an air permeable filter disposed in the filter holder; wherein the predetermined shape of the filter holder shapes the air permeable filter to be angled; and an attachment mechanism for securing the housing to an enclosure that houses heat generating electronics second attachment mechanism for securing the filter holder to the housing; wherein the second attachment mechanism for securing the filter holder to the housing comprises a hinge mechanism that permits one side of the filter holder to release from the housing and another side of the filter holder to be attached to the housing via the hinge mechanism.",
    "9. The apparatus of claim 8, wherein the air permeable filter is angled 45 degrees.",
    "10. The apparatus of claim 8, wherein the air permeable filter is arced.",
    "11. The apparatus of claim 8, comprising a fan that moves air in one or more directions through the housing."

  "description_excerpt": "The subject matter disclosed herein relates to enclosure cooling systems and related techniques. Some of the subject matter disclosed herein relates to cooling systems mounted to the sides of an enclosure and used for cooling items within the enclosure.\n\nIndustry and manufacturing have emerged with the widespread use of enclosures for a variety of content, for example electronics or other items that require protection from the elements as well as cooling. For example, to protect these items from harsh environments, they are typically placed in sealed enclosures or work stations that permit efficient operation without the threat of being exposed to exterior contaminates including dust, residue, rain and liquids that have the potential to cause serious damage. Since the items (such as electronics or like equipment) often generate heat within the enclosure, various cooling equipment such as air conditioners, heat exchangers, in-line compressed air coolers and filtered fan systems are used to maintain required operating temperatures within the enclosure.\n\nCertain cooling systems often treat the enclosed air only, while sealing out the potential contaminated ambient environment. In cases where the ambient air is near room temperature (70-85 degrees Fahrenheit) and when there is not a threat of rain or splashing liquids present outside the enclosure, a filtered fan system is used to maintain a constant flow of filtered ambient air through the enclosure.",
