Because the touch temperature of a wearable computing device ('WCD') may be an insignificant factor for user experience when the WCD is not being worn by a user, embodiments of the solution seek to modify thermal management policies based on an inferred user proximity state. Exemplary embodiments monitor one or more signals from readily available sensors in the WCD that have primary purposes other than measuring user proximity. Depending on embodiment, the sensors may be selected from a group consisting of a heart rate monitor, a pulse monitor, an O2 sensor, a bio-impedance sensor, a gyroscope, an accelerometer, a temperature sensor, a pressure sensor, a capacitive sensor, a resistive sensor and a light sensor. Using the signals generated by such sensors, relative physical proximity of the WCD to a user may be inferred and, based on the user proximity state, thermal policies either relaxed or tightened.

System and method for thermal management of a wearable computing device based on proximity to a user

An apparatus for cooling an electronic device is disclosed. In an aspect, the apparatus includes a vapor chamber coupled to a heat generating component of the electronic device. In an aspect, the vapor chamber is coupled to an inner surface of an outer cover of the electronic device and conforms to a shape of the inner surface of the outer cover. In another aspect, the vapor chamber forms the outer cover of the electronic device. The vapor chamber comprises a sealed container, a wick structure disposed on an inner surface of the sealed container, and a fluid contained in the sealed container, wherein as heat is applied to an evaporator side of the sealed container coupled to the heat generating component, the fluid vaporizes over a condenser side of the sealed container opposite the evaporator side and returns to the evaporator side via the wick structure.
