Samsung patents phone design with heat spreaders between battery and screen

Samsung describes a smartphone layout where a heat-spreading material sits between the main circuit board, the battery, and the screen. The design uses a specific internal support structure to hold a battery that has a thinner section, allowing the heat spreader to cover both the electronics and the power source.

Why it mattersThis filing details how manufacturers can better manage heat in thin phones by placing cooling materials in tight spaces between the battery and the display.

In the filing’s own words

An electronic device includes: a housing; a display disposed on one surface of the housing; a printed circuit board disposed in an interior of the housing; a battery disposed in one direction of the printed circuit board in the interior of the housing, the battery includes a first portion and a second portion located at an end facing the printed circuit board; and a thermal diffusion member between the printed circuit board and the display and between the battery and the display. The thermal diffusion member includes a first diffusion portion which at least a portion of overlaps with the printed circuit board and at least a portion extends in the first portion of the battery, and a second diffusion portion between the second portion of the battery and the first diffusion portion and extended to be overlapped with at least a portion of the second portion of the battery.

What exactly they claim (claim 1)

1. An electronic device comprising: a display; a rear cover; a housing at least partially disposed between the display and the rear cover such that a first surface of the housing faces toward the display and a second surface opposite to the first surface of the housing faces toward the rear cover, the housing including a placement space formed therein and a support structure formed on the second surface, the support structure including a first support portion extended in a first direction substantially perpendicular to the second surface and a second support portion extended from the first support portion in a second direction substantially perpendicular to the first direction, the first support portion and the second support portion integrally formed with each other; a thermal diffusion member at least partially disposed in the placement space; a printed circuit board at least partially disposed at a first side facing in a third direction opposite to the second direction with respect to the first support portion between a first diffusion portion of the thermal diffusion member and the rear cover; and a battery at least partially disposed at a second side facing in the second direction with respect to the first support portion between a second diffusion portion of the thermal diffusion member and the rear cover, the battery including a first battery portion having a first thickness, and a second battery portion extended from the first battery portion in the third direction and having a second thickness thinner than the first battery portion, wherein the second battery portion is at least partially disposed between the second support portion and the rear cover, and wherein the second support portion is at least partially disposed between the second diffusion portion of the thermal diffusion member and the second battery portion.
