[0031] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0032] According to some embodiments of the present invention, with reference to Figures 1 to 4, the integrated heat dissipation and shielding structure includes a power supply board 100, a heat dissipation aluminum seat 200, and a heat conducting plate 140.
