Heat Dissipation Structure for Hand-Held Mobile Devices

Solution Overview

Problem

Current hand-held mobile devices face challenges in efficiently dissipating heat without increasing their overall thickness, volume, or occupying internal space, as conventional heat dissipation methods like using graphite materials are not feasible due to compactness and weight constraints.

Innovation Solution

A heat dissipation structure featuring a supporting body with integrated heat dissipation elements, such as vapor chambers or thin heat pipes, that are flush with the device's sides, allowing for effective heat transfer without protruding and thus maintaining device thickness and volume, utilizing heat absorption and dissipation surfaces for efficient heat management.
