Patent ID: 7855891

Claim:
An enclosure for outside plant electronic equipment, comprising: a. a cast housing having a main body and a cover; b. an electronic circuit board, having opposing sides and electrical components on both sides; c. a first substantially planar configured heat sink plate mounted to said main body, said first heat sink plate having thermal conductors formed on a surface of the heat sink plate and configured to engage the electrical components on the electronic circuit board and transfer heat by conduction through the thermal conductors from the electrical components to said main body, and further comprising a resilient, thermally conductive material positioned between the thermal conductors and the electrical components and dimensioned for a frictional fit therebetween and, selected depending on the application and the amount of thermal flow needed, and further comprising one of a resilient, thermally conductive grease or thermally conductive resilient material between the heat sink plate and the main body; and a second substantially planar configured heat sink plate mounted to the cover such that the electronic circuit board is mounted between the first and second heat sink plates and said second heat sink plate comprising thermal conductors formed on a surface of the second heat sink plate and configured to engage the electrical components on the electronic circuit board and transfer heat by conduction through the thermal conductors from the electrical components to the cover, and further comprising a resilient, thermally conductive material positioned between the thermal conductors and the electrical components and dimensioned for a frictional fit therebetween and selected depending on the application and the amount of thermal flow needed, and further comprising one of a resilient, thermally conductive grease or thermally conductive resilient material between the second heat sink plate and the cover.
