Patent ID: 8512430

Claim:
An enclosure, comprising: a housing having a cavity and a first opening in a first wall of the cavity, wherein the first opening comprises first mating threads; a first filter holder comprising second mating threads that complement the first mating threads, wherein the first filter holder couples to the first opening of the housing by rotating the second mating threads into the first mating threads, and wherein the first filter holder is positioned within the first opening when the first filter holder is threadably coupled to the housing; a first sintered filter coupled to the first filter holder, wherein the first sintered filter allows heated air to pass therethrough between the cavity and an exterior of the housing; a first fan positioned within the housing and proximate to the first sintered filter, wherein the first fan, in conjunction with the first sintered filter, creates a pressure differential to force the heated air through the first sintered filter; and a cylindrical tubing coupled to the first filter holder, wherein the cylindrical tubing is bent to prevent water from entering the cavity, wherein the first sintered filter cools the cavity by passing the heated air to the exterior of the housing.
