    摘要： Filters and filtering methods for placement in an electronic enclosure, such as a hard disk drive housing, are disclosed. In one embodiment the filter includes a housing having a top, a base, and at least one sidewall extending from the top to the base, the housing defining an inlet port and an outlet port through the sidewall, and a breather port in the base, the housing further defining an internal volume. Adsorbent filter media is disposed within the internal volume of the housing such that the housing defines a first path for flow of fluid through the breather port in the base to the filter media and a second path for flow of fluid through the inlet port, into contact with the filter media, and out the outlet port.

    摘要： A one-way fill valve for use in electronic enclosures is disclosed. The one-way fill valve allows an inert gas to be added to an electronic enclosure without contamination and without excessive leakage. A scrim layer is provided between a breathable layer and a sealing element to protect the breathable layer from possible rupture and allow for greater air flow across the breathable layer.

    摘要： A filtering apparatus (12) includes a filter cartridge (28) which may be replaced or cleaned and re-used. The filter apparatus also includes a heat exchanger (62) which receives cooling air to cool the exhaust prior to filtering. The cooled exhaust does not pose combustion problems for soot or the filter material in the cartridge (28). In addition to cooling the exhaust, a temperature-sensitive valve (36) opens and closes to prevent excessively hot exhaust gas from reaching the filter cartridge (28). The valve (36) includes bi-metal discs (52) which bow outward when the temperature increases and flatten when the temperature decreases. The discs engage a cover to an orifice and slide axially to open and close the valve (36). The apparatus also may include a back pressure valve (72) which will open when the exhaust flow is backed up to prevent damage to the engine.

    摘要： Filters, methods, and an apparatus for filling housings and both encapsulated porous and non-porous spaces with contaminant control media for placement in electronic enclosures, such as disk drive enclosures, are disclosed. In one embodiment, a filter assembly includes a housing comprising an internal cavity configured to receive contaminant control media, a fill port in communication with the internal cavity, and an opening in communication with the internal cavity, and filter media at least partially covering the opening; and contaminant control media occupying the internal cavity. Contaminant control media is deposited within the internal cavity via the fill port by means of creating a negative pressure within the internal cavity. The application of a partial vacuum facilitates movement of the contaminant control media into the internal cavity and minimizes the contamination of the filter, housing, and work space common to other loose fill filling methods.
