Abstract

The invention discloses a heat dissipation processing device and a mobile terminal. The device comprises a mobile terminal metal stand subjected to low-thermal-conductivity surface removal treatment, a first heat conducting material with rough surface, and a PCB (printed circuit board) with a multilayer structure, wherein the mobile terminal metal stand is located between a mobile terminal LCD (liquid crystal display) and the PCB; the space between the mobile terminal metal stand and the PCB is filled with the first heat conducting material; large-power devices on the PCB are arranged at a middle position of the device surface of the PCB, and are kept with gap between the devices; at least one layer of ground copper is arranged in the PCB; ground copper is arranged on the bottom or other positions of the large-power devices on the device surface of the PCB; and a ground hole is formed on the device surface of the PCB. Based on the technical scheme provided by the invention, the heat dissipation processing device provided by the invention can improve the overall electromagnetic compatibility index, radio frequency index and structural reliability index while the mobile terminal electronic system is subjected to the effective heat dissipation treatment.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a heat dissipation treatment device and a mobile terminal. Background technique [0002] In the prior art, a mobile terminal is especially an intelligent terminal based on the third-generation mobile communication technology (3rd-generation, referred to as 3G) and the long-term evolution (Long Term Evolution, referred to as LTE) system. The frequency is getting higher and higher, the memory access speed is getting faster and faster, and the power consumption of RF power amplifier and power management is also getting higher and higher. Therefore, the heat dissipation treatment (also called thermal design) of mobile terminals is particularly important. [0003] Thinner appearance and more complex functions are the two sides of a smart mobile terminal. On the one hand, it has a cool body and colorful applications; In the era of development, thermal design is very important. [...
