Heat-dissipating base

Abstract

A heat-dissipating base includes a main body. The main body has a basic portion. Four corners of the basic portion are respectively connected to a first extending arm, a second extending arm, a third extending arm and a fourth extending arm. Both sides of the first, second, third, and fourth extending arms are respectively provided with a first bending portion, a second bending portion, a third bending portion and a fourth bending portion. An end of the first, second, third, and fourth extending arms opposite to the basic portion is respectively formed with at least one positioning hole. The first, second, third and fourth bending portions are configured to increase the structural strength of the first, second, third and fourth extending arms respectively.
