Notebook computer with high heat dissipation performance

The notebook computer with the high heat dissipation performance comprises a notebook computer body, a display screen is connected to the notebook computer body through a damping rotating shaft, a camera is arranged at the upper end of the front face of the display screen, and a heat dissipation opening and a containing groove are formed in the lower surface of the notebook computer body. The containing groove is located in the outer side of the heat dissipation opening, a supporting rod is rotationally arranged on the inner side of the containing groove, a supporting block is arranged at thelower end of the supporting rod, and a rotating column is rotationally arranged on the inner side of the supporting block. By arranging the supporting rod, the supporting block, the containing groove,the wear-resisting bottom plate, the limiting block, the rotating column and the spring, the situation that due to the fact that the distance between the lower surface of the notebook computer body and the containing face is
