| 摘要 |
The invention relates to a novel cooling system (100) in which waste heat that is to be dissipated is firstly absorbed by an electron emission layer (15). The heat induces a discharge of electrons (13) from the surface of the electron emission layer, whereby the electrons are drawn off by a suction electrode (10), which is located on a positive potential located opposite the emission layer (15). The thermal energy carried along by the electrons (13) induces a heat transfer from the electron emission layer (15) to the suction electrode (10). The intensity of the electron flow can be controlled by the bias voltage of a grid (12), which is arranged between the electron emission layer (15) and the suction electrode (10). The surface of the electron emission layer (15) is preferably comprised of alkaline-earth metals such as barium or cesium.
