Abstract

Disclosed is a mobile terminal. The mobile terminal comprises a first circuit board; a first charge chip arranged on the first circuit board; a power supply management chip arranged on the first circuit board; a second circuit board; a second charge chip which is arranged on the second circuit board and is connected in parallel with the first charge chip; and a temperature measurement part which is arranged on the second circuit board and is connected with the power supply management chip. The mobile terminal can monitor and control the temperature of the second circuit board in real time and improves the performance of the mobile terminal.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a mobile terminal. Background technique [0002] As the battery capacity of the mobile terminal increases, the charging time of the battery becomes longer and longer. In the prior art, dual charging chips are used to quickly charge the battery, which can effectively shorten the charging time of the battery. [0003] The charging chip is generally arranged on the main board of the mobile terminal. During the charging process, the temperature of the charging chip will rise, resulting in a relatively large temperature rise of the main board. For the charging scheme with dual charging chips, the temperature rise of the main board is even greater. [0004] At present, the mainstream heat dissipation method is to use water-cooled heat-conducting copper tube technology to conduct heat to other places through copper tubes for heat dissipation, but the cost is relatively high, ...
