Samsung patents phone design with layered heat spreaders

Samsung describes an electronic device layout where a thermal diffusion member sits between the main circuit board, the battery, and the screen. This member has two distinct sections that align with different parts of the battery to move heat away from sensitive components.

Why it mattersThis is a standard engineering approach to managing heat in thin devices, ensuring the phone stays cool during heavy use.

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 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 an interior of the housing, the battery comprising a first portion and a second portion, the second portion having a thickness less than a thickness of the first portion and the second portion being located at an end of the battery which faces the printed circuit board; and a thermal diffusion member disposed between the printed circuit board and the display and between the battery and the display, wherein the thermal diffusion member comprises: a first diffusion portion which at least a portion of overlaps with the printed circuit board and which at least a portion of extends to in the first portion of the battery; and a second diffusion portion disposed between the second portion of the battery and the first diffusion portion and extended to be overlapping with at least a portion of the second portion of the battery.
