RECIRCULATION FILTER FOR AN ELECTRONICS ENCLOSURE

摘要

One aspect of the technology relates to a recirculation filter. The recirculation filter has a first outer layer defining at least a portion of a first flow face of the recirculation filter, where the first flow face is configured to be positioned adjacent to a sensitive component in an electronics enclosure. A second outer layer defines at least a portion of a second flow face of the recirculation filter. A filter material layer is disposed between the first outer layer and the second outer layer. The filter material layer has a central region, wherein a substantial portion of the central region is offset from the first flow face of the recirculation filter. Other aspects are also described.

1. A recirculation filter comprising:
a first outer layer having a distal end defining the location of a first flow face of the recirculation filter; a second outer layer having a distal end defining a second flow face of the recirculation filter; and a filter material layer disposed between the first outer layer and the second outer layer, wherein an offset is defined between the filter material layer and the first flow face, wherein the ratio of the thickness of the recirculation filter to the combined material thickness of the first outer layer, the second outer layer, and the filter material layer is from about 1.05 to about 10.
