Abstract:
An electronic device comprising:a housing that has a rectangular parallelepiped shape having a thin dimension in a height direction thereof; a central chassis positioned inside said housing, in the middle part of said housing in said height direction, said central chassis having a shelf that separates said housing into an upper section and a lower section; heat-generating components positioned in said lower section within said housing relative to said central chassis and a heat-conducting member connected to said heat-generating components for conducting heat away from said heat-generating components; a heat sink member extending through a first opening in said shelf between said upper and lower sections and thermally connected to said heat-generating components via said heat-conducting member; a power source unit provided on said upper section, said power source unit for providing power to said electronic device; an exhaust fan provided on a side end of said housing; a second opening provided in said housing on a side end opposite said exhaust fan; and first and second cooling air channels extending between said exhaust fan and said second opening; wherein said first cooling air channel is formed in said lower section with respect to said central chassis, and wherein said second cooling air channel is formed in said upper section with respect to said central chassis, said heat sink member being positioned in said second cooling air channel at a location that is upstream from said power source unit.
