Title:
TERMINAL DEVICE AND HEAT-DISSIPATION STRUCTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/197846
Kind Code:
A1
Abstract:
The present invention relates to the field of electronic technology. Disclosed herein are a terminal device and a heat-dissipation structure thereof. The heat-dissipation structure comprises: a substrate, a heat-generating element, a thermal conductor and a shell which are stacked in sequence from bottom to top, and a shield frame provided between the substrate and the shell; the substrate, the shield frame and the shell enclose to form an accommodation space, and the heat-generating element and the thermal conductor are accommodated in the accommodation space; the thermal conductor comprises at least a first thermally-conductive layer which is made of a thermally-conductive phase change material. Thus, by filling the thermal conductor which comprises the first thermally-conductive layer made of a thermally-conductive phase change material and which is provided between the shell and the heat-generating element, the thermal conductor can dynamically adapt to a gap between the heat-generating element and the shell, along with changes in temperature during the operation of the terminal. On the one hand, the present invention ensures that a gap does not exist between the shell and the shield frame when the terminal is in a working state, thus ensuring electromagnetic shielding performances; on the other hand, the thermal conductor is always kept in sufficient contact with the heat-generating element and the shell, respectively, so as to maintain an unimpeded path for heat dissipation, thus ensuring heat-dissipation performances.
