Asbestos Containing Patents (Class 106/625)
  • Patent number: 9665138
    Abstract: Micro-hole vents for device ventilation systems are described herein that may be formed as a plurality of micro-holes that are invisible to unaided human eyes. The micro-holes are configured to blend into the housing for a computing device such that the holes are substantially concealed from users of the computing device. A micro-hole vent may be aligned with a blower for a ventilation system to enable air intake through the corresponding micro-holes for cooling of components within the housing. In addition or alternatively, one or more exhaust vents for the ventilation system may also be configured as micro-hole vents. Each micro-hole vent may have many, very small holes for sufficient air flow. For example, micro-holes having diameters of about fifty to two hundred microns may be arranged in a pattern with a coverage in a range of about twelve thousand to fifty thousand holes per square inch.
