Abstract
A set-top box is provided that comprises a housing having a first vertical outer wall with a first vent and a second vertical outer wall with a second vent; a circuit board having a first heat source element and a second heat source element; a contoured heatsink in thermal engagement with the first heat source element, wherein the contoured heatsink overlies at least one-third of the circuit board and extends along the first vertical side wall; and a second heatsink contacting the second heat source element, wherein the second heatsink is located in only one half of the device and is aligned with the second vent. The multiple heatsinks and associated vents work in concert to improve heat dissipation.
