Heat dissipation case and methods for navigating heat from an electronic device

A method for forming an accessory device having a shell, wherein the shell includes a back wall having a through hole, the shell configured to secure an electronic device and aid in navigating heat away from a heat-generating component in the electronic device, the method comprising:

• embedding a platform of a thermally conductive layer in the back wall in a first location that corresponds to a location of the heat-generating component when the electronic device is secured by the shell;
• embedding a central portion of the thermally conductive layer that is connected to the platform;
• and
• embedding an extension of the thermally conductive layer in a second location of the back wall that is different from the platform and the central portion, the platform, the central portion, and the extension formed from a thermally conductive foam, the extension connected to the central portion and laterally offset with respect to the platform and located closer to the through hole than the platform, the thermally conductive layer defining a path along which the heat flows from the first location to the second location, the path occupying a limited portion of the back wall, wherein the platform, the central portion, and the extension are concealed in the back wall, and wherein the heat at the extension is dissipated from the thermally conductive layer to the through hole.

An accessory device capable of removably coupling with an electronic device that includes a heat-generating component configured to generate heat, the accessory device comprising:

• a shell defining an interior volume having a size and shape corresponding to that of the electronic device, the shell comprising a first through hole and a second through hole;
• a first layer covering a first surface of the shell except for the first through hole and the second through hole, the first layer capable of engaging the electronic device when the electronic device is positioned in the interior volume;
• a second layer covering a second surface of the shell except for the first through hole and the second through hole, the second layer different from the first layer;
• and
• a thermally conductive foam embedded in the shell between, and covered by, the first layer and the second layer, the thermally conductive foam comprising i) a first portion positioned at a location corresponding to the heat-generating component, and ii) a second portion extending continuously from the first portion between the first through hole and the second through hole, the thermally conductive foam capable of transferring the heat received at the first portion to the second portion.
