Abstract
The invention relates to a novel cooling system ( ) in which waste heat to be dissipated is first absorbed by an electron emission layer ( ). The heat induces a discharge of electrons ( ) from the surface of the electron emission layer, whereby the electrons are drawn off by a suction electrode ( ) which is located on a positive potential located opposite the emission layer ( ). The thermal energy carried along by the electrons ( ) induce a heat transfer from the electron emission layer ( ) to the suction electrode ( ). The intensity of the electron flow can be controlled by the bias voltage of a grid ( ) which is arranged between the electron emission layer ( ) and the suction electrode ( ). The surface of the electron emission layer ( ) is preferably composed of alkaline earth metals such as barium or cesium.
