Abstract

The invention relates to the field of mobile communication, and provides a mobile terminal, which comprises a first circuit board, a second circuit board and a battery, wherein the first circuit board is located at the bottom of the battery; the second circuit board is located at the top of the battery; the first circuit board is provided with a first charging IC; the second circuit board is provided with a CPU; and the first charging IC is used for charging the battery. The mobile terminal has good cooling effects in the case of charging.

Description

technical field [0001] The invention relates to the field of mobile communications, in particular to a mobile terminal that is good for heat dissipation. Background technique [0002] With the rapid development of mobile communication technology, the continuous upgrading of mobile terminal hardware and the increasing number of new functions, the integration and density of devices on the motherboard of mobile terminal products are getting higher and higher, but are limited by the size of the mobile terminal and the The thickness of the battery, the space of its motherboard is gradually compressed. ICs (Integrated Circuit, integrated circuit) that realize communication, display, sound, charging and other different functions are densely distributed on the motherboard, resulting in too concentrated heat sources and poor heat dissipation environment for mobile terminals. When the user is using the mobile terminal, especially when using the mobile terminal while charging, the mob...
