Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

Referring to Figures 1-4, a mobile phone middle frame with high heat dissipation includes an inner frame 1. The inner frame 1 is a rectangular frame composed of two sets of side plates 11 and two sets of connecting plates 12. The inner frame 1 is an integrally formed metal structure. The length of the side plate 11 is greater than the length of the connecting plate 12, two groups of side plates 11 are equidistantly provided with heat dissipation holes 2, semiconductor heat sinks 3 are arranged in the heat dissipation holes 2, heat dissipation windows 4 are arranged on the two groups of connecting plates 12, The outer side of the inner frame 1 is slidably connected with an outer frame 5, and the inner frame 1 and the outer frame 5 are provided with functional openings such as a switch button hole, a volume button hole, an earphone and a USB interface, and the outer frame 5 includes a first frame 51 and a second frame 51.
