System and method for removing heat from a subscriber optical interface
First Claim
1. A heat removal system comprising:
- a housing comprising an opening;
a plate positioned over the opening;
a standoff positioned on a side of the housing adjacent to the opening and extending in a direction away from the housing;
a printed circuit board and a heat producing element disposed on the printed circuit board;
heat conductive material positioned between the heat producing element and the plate; and
projections extending from the plate and extending in the same direction as the standoff, whereby the projections transfer heat away from an interior of the housing.

Abstract
A system and method removes heat from an enclosure or housing of a subscriber optical interface. When a subscriber optical interface housing is attached to a structure such that a partially enclosed volume of space remains between the structure and the subscriber optical interface housing, this partially enclosed volume of space can produce a chimney effect when heat from the subscriber optical interface housing is intended to flow from fins towards the structure. This chimney effect can refer to a fluid such as air within the partially enclosed space that is heated by the fins and that rises upward when the ambient or surrounding fluid is cooler relative to the heated fluid. According to another exemplary embodiment, the subscriber optical interface can be shaped to form an internal chimney structure that is entirely surrounded by a housing of the subscriber optical interface.

21. A method for removing heat from a utility enclosure comprising:
-
positioning and shaping fins to maximize a chimney effect;
determining a position of a printed circuit board comprising heat producing elements relative to the enclosure in order to maximize the chimney effect;
placing the printed circuit board in the position;
blocking transfer of heat from an external environment relative to the enclosure with a shield; and
applying a heat conductive material between the heat producing components and a plate in order to maximize heat transfer from the heat producing components to the fins. - View Dependent Claims (22, 23, 24)

25. A heat removal system comprising:
-
a housing comprising an aperture;
a plate positioned over the aperture;
fins protruding from the plate away from the aperture and external to the housing; and
a shield coupled to the fins for blocking any heat radiating from outside the housing into the fins, whereby the fins transfer heat from inside the housing to outside the housing. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)
