Claim 0:
1. A casing structure with functionality of effective thermal management, being applied in an electronic device for achieving a heat dissipation of a heat source, and comprising:
at least one thermal conductive member, being disposed on the heat source, and being selected from a group consisting of graphite sheet, sheet-metal radiator and sheet-ceramic radiator;
a heat spreader, being disposed on the thermal conductive member, and being a thermal ground plane (TGP);
a low thermal conductivity medium, being disposed on the heat spreader, and having a thermal conductivity that is less than 0.2 W/m·K;
a casing member, being made of a material selected from a group consisting of Mg—Li alloy, Mg—Li—Al alloy, Mg—Al alloy, Mg—Mn alloy, and Mg—Zr alloy, and being disposed on the low thermal conductivity medium, such that the heat thermally transferred from the low thermal conductivity medium to the casing member is consequently dissipated away from the casing member to air; and
a surface treatment coating, being deposited on an inner surface and/or an outer surface of the casing member, and being selected from a group consisting of anodizing treatment coating and ceramic coating;
wherein in case of the heat source generating a heat, the thermal conductive member transfers the heat to the heat spreader, and then the heat spreader two-dimensionally spreads the heat;
wherein the low thermal conductivity medium with the thermal conductivity of less than 0.2 W/m·K transfers the heat from a surface of the heat spreader to the casing member, so as to well control an outer surface temperature of the casing member during the heat being dissipated into air.
