Patent ID: 7408777

Claim:
A plasma display device comprising: a plasma display panel having a planar viewing surface, the planar viewing surface having a rectangular perimeter; a circuit unit for supplying a driving signal to the plasma display panel; and a cavity-type heat dissipator having a circuit unit interface adapted to be affixed to a predetermined portion of the circuit unit to dissipate heat generated at the circuit unit, the cavity-type heat dissipator having wings protruding from the circuit unit interface, wherein the wings extend from edges of the circuit unit interface toward an interior area of the circuit unit interface for forming at least two sets of air channels, each set of the air channels directing airflow across the circuit unit interface in directions parallel to the planar viewing surface while substantially perpendicular to an edge of the rectangular perimeter, and wherein the at least two sets of air channels are substantially perpendicular to each other, and air channels within a set of the at least two sets of air channels are substantially parallel to each other.
