THERMIONIC GENERATOR Russian patent published in 2010 - IPC H01J45/00 H02N3/00 

FIELD: electricity.

SUBSTANCE: thermionic generator includes current leads (16), cathode with heat supply devices (7) and perforated anode (12) with heat discharge devices, which are separated with an interelectrode gap (8), supply system of cerium steam through holes in anode (10) to interelectrode gap (8). Supply system of cesium steam through holes in anode (10) to interelectrode gap (8) is formed with perforated anode (12), capillary-porous gasket (6) soaked with cesium alloy and anode substrate (13), which are all connected to each other. At least some part of holes (10) in anode is arranged above heat-insulating gaskets (14) arranged on anode substrate (13). In particular cases of device version the distance between holes in perforated anode (12) is 0.7-4 of thickness of interelectrode gap (8), and size of holes in perforated anode (12), which are located above heat-insulating gaskets (14), is at least twice as small than holes in perforated anode (12), which are arranged outside heat-insulating gaskets (14).

EFFECT: increasing efficiency of energy conversion and improving compactness of device.
