SYSTEM FOR COMPENSATION OF EXPANSION/CONTRACTION OF A COOLING MEDIUM INSIDE A SEALED CLOSURE

摘要

A closure (100) protects telecommunications circuitry from environmental factors. The closure includes a base (128) having a sidewall (134) extending upwardly from a bottom (118), the sidewall (134) defining at least one cable port (122). The closure also includes a cover (126) that attaches to the base (128) to close an interior (130) of the closure (100). In addition, electronic circuitry (132) disposed within the interior (130) of the closure (100). Encompassing the electronic circuitry (132) is a cooling medium (138) dispersed through the interior (130). Further, a pressure regulating device (136) is placed in the interior (130) to maintain a viable internal operating pressure for the closure.
