Abstract
A heat-dissipating device is disclosed for use in an electronic device. This heat dissipating device includes a reservoir for holding a substance in a liquid state (e.g., water) and at least one heat transfer point for transferring heat from a heat source, such as a component in the electronic device, to the liquid substance. Heat causes the substance to transform into a gaseous state due to the transfer of thermal energy from the heat source to the substance. A gas permeable membrane is used to permit the substance to escape the reservoir when it is in a gaseous state while, at the same time, preventing the substance from escaping when it is in a liquid state.
