The heat dissipation holes 21, the heat dissipation grooves 11, and the frame body can dissipate heat at the same time, so that the heat dissipation effect is better and the heat dissipation performance is high.

As shown in fig. 1 to 5, the small mobile phone plate support with high heat dissipation performance includes an aluminum alloy frame 10, a plastic plate 20, and a graphite temperature-uniforming plate 22; the plate body 20 is integrated with the frame body 10 by adopting an injection molding process; the graphite temperature-equalizing plate 22 is arranged on the top of the frame body 10 and the plate body 20; the joint between the plate body 20 and the frame body 10 is provided with an occlusion tooth connection; a plurality of heat dissipation holes 21 are hollowed out on the plate body 20; the bottom of the frame body 10 is provided with a plurality of heat dissipation grooves 11; a plurality of positioning notches 23 are arranged at intervals on the edge of the frame body 10. The graphite heat conducting plate has excellent heat conducting performance, very high heat conducting speed and high heat flux. Therefore, the graphite temperature-uniforming plate 22 has temperature-uniforming and high heat-conducting characteristics. The graphite vapor chamber 22 has contact surfaces with both the frame body 10 and the plate body 20. Therefore, the graphite temperature-uniforming plate 22 can rapidly transmit heat to the frame body 10 for heat dissipation, and the graphite temperature-uniforming plate 22 can make the heat uniform without local high temperature, thereby being beneficial to protecting the circuit board. The plate body 20 is provided with the heat dissipation holes 21, so that the heat of the temperature equalizing plate can be dissipated through the heat dissipation holes 21, the bottom of the frame body 10 is provided with a plurality of heat dissipation grooves 11, the heat dissipation area of the frame body 10 is further increased, and the heat dissipation effect is better. The graphite temperature-uniforming plate 22 is arranged to skillfully utilize the frame body 10 for heat dissipation. Therefore, the graphite temperature-uniforming plate 22, the heat dissipation holes 21, the heat dissipation grooves 11 and the frame body 10 have better heat dissipation effect and higher heat dissipation efficiency. The positioning notch 23 arranged at the edge of the frame body 10 is beneficial to the installation of the small mobile phone plate support, and the installation is more convenient. The heat dissipation holes 21 and the heat dissipation grooves 11 may be formed in a circular shape, a rounded rectangular shape, or the like.

Preferably, the frame body 10 is shaped like a U, and the plate body 20 is embedded in the frame body 10. The plate body 20 is rectangular, the frame body 10 is U-shaped, and the plate body 20 is embedded in the frame body 10, so that the plate body 20 is not easy to loosen and has good integrity.

Further, the plate body 20 is provided with two edges which are integrated with the frame body 10; wherein, two rows of plate body meshing teeth 24 are arranged at the edge joint of the plate body 20, and a partition plate is arranged between the two rows of plate body meshing teeth 24; two rows of frame body occlusion teeth 12 are arranged at the edge joint of the frame body 10, and a gap for inserting the partition plate 29 is reserved between the two rows of frame body occlusion teeth 12.
