Abstract

The invention discloses a notebook computer structure with an upper cover used for conducting and dissipating heat. The notebook computer structure comprises the upper cover and a seat, wherein the upper cover is formed by a cover A, a display screen, a heat conduction pipe and a circuit board. A rotary shaft, heat dissipation fins and a heat pipe attaching surface are arranged on the cover A, the heat conduction pipe is formed by a heat dissipation end and a plurality of heat absorption ends, the circuit board is attached to the back surface of the display screen and arranged in the cover A, and the heat conduction pipe is arranged between the cover A and the circuit board. By arranging the heat conduction pipe in the upper cover, heat in a notebook computer can be directly conducted to the outside of the upper cover in a heat conduction mode to perform heat dissipation. Due to the fact that a heat dissipation air fan and a special heat dissipation member are omitted, the notebook computer is lighter and thinner, no noise is generated, and the real silenced notebook computer is achieved.
