Abstract
An apparatus and method of the disclosure provides a cooling mechanism for a handheld electronic device. The cooling mechanism includes a heat sink and an evaporative cooling mechanism. The evaporative cooling mechanism includes liquid retaining structures. The liquid retaining structures are located in proximity to the at least one IC of the handheld electronic device. Each liquid retaining structure is coated with a temperature sensitive polymer that act as hydrophilic when the temperature of the surface of the handheld electronic device is below a threshold temperature. To maintain the temperature of the surface of the handheld electronic device below the threshold temperature, the temperature sensitive polymer act as hydrophobic and evaporates the liquid stored in the liquid retaining structures to the atmosphere surrounding the handheld electronic device when the temperature of the surface of the electronic device is above the threshold temperature.
