Abstract: Techniques for monitoring surface temperature of devices are described. Generally, surface temperature of devices is monitored and controlled to prevent user discomfort and/or injury that may result from user contact with an excessively heated surface. In at least some embodiments, temperature of an external surface of the device is indirectly monitored. For instance, a temperature sensor is positioned at an internal location in a device that has a known temperature relationship to a temperature of an external surface of the device. Alternatively or additionally, a temperature of an external surface of a device may be directly detected. In at least some embodiments, when a temperature of an external surface of a device is determined to reach or exceed a threshold temperature, procedures can be implemented to reduce the temperature of the external surface and/or prevent further heating of the external surface.

Abstract: A lost wax cast vapor chamber device is provided. Once a mesh is produced, a meltable core is formed from a meltable core material with the mesh positioned at least partially inside the core. Over the meltable core a metallic layer is formed, at least partially surrounding the meltable core.

Subsequently, the internal void is filled at least partially with a working fluid and the opening is closed. The mesh supports the surfaces of the chamber against deformation under the vacuum of the internal void. Movement of working fluid by capillary action is facilitated by the mesh.
