Portable computer having a heat-emitting device mountable on a CPU for emitting heat generated from the CPU via air ventilation holes formed on a keyboard

摘要

A portable computer having a heat-emitting device and includes a CPU board; a CPU mounted on the CPU board; a first heat emitting member directly mounted on a top surface of the CPU for emitting heat generated from the CPU; a second heat emitting member having a large surface area for dissipating the heat emitted from the first heat emitting member by heat conduction; a top board having a first plurality of perforated apertures, positioned on the second heat emitting member for passing the heat dissipated from the second heat emitting member to the outside of the portable computer; a key frame having a second, complementary to the first, plurality of perforated apertures, positioned on the top board for passing the heat passed through the top board to the outside of the portable computer; and a keypad supported by the key frame and having a third, complementary to the first and second, plurality of perforated apertures for passing the heat passed through the key frame to the outside of the portable computer. As a result, the heat generated from the CPU which is used to circulate in the interior of the portable computer is now efficiently emitted to the outside of the portable computer through air ventilation holes of a keyboard or a heat emitting plate connected thereto.
