Thermally conductive: An object, device, or assembly (which may comprise multiple distinct bodies that are thermally coupled, and may include multiple different materials), is “thermally conductive” between two thermal interfaces if any one of the following is true: (1) a heat transfer coefficient between the thermal interfaces is 10 W·m?2·K?1 or greater at any temperature between 0° C. and 100° C., (2) the object is continuous piece of a material that has a thermal conductivity (often denoted k, λ, or κ) between the two interfaces of 1 W·m?1·K?1 or greater at any temperature between 0° C. and 100° C., (3) the object is a heat pipe, vapor chamber, continuous body of copper, or continuous body of aluminum. Examples of materials whose thermal conductivity is greater than 1 W·m?1·K?1 between 0° C. and 100° C. include almost all metals and their alloys (e.g., copper, aluminum, gold, etc.), some plastics (e.g., TECACOMP? TC compounds, CoolPoly? D-series Thermally Conductive Plastics), and many other materials.
