Problems solved by technology

[0002] At present, thermionic power stacks based on vacuum thermionic power generation diodes, such as nuclear or solar energy, have the disadvantage that the electrode surface area is small and the power generation efficiency is low. For example, the efficiency of nuclear thermionic power stacks for nuclear submarines is only about 6%.

Embodiment Construction

[0006] In the honeycomb thermionic power stack of the present invention, tungsten or tungsten-rhenium alloy is used as the honeycomb plate-shaped cathode in each hexagonal honeycomb hole, and there is laser sintered lanthanum hexaboride or carbon nanotube and other high-efficiency electron emission coatings. The diameter of each hexagonal nail plate-shaped anode made of tungsten-niobium alloy is about 3 mm smaller than the honeycomb aperture to ensure that there is a gap of about 1.5 mm after the two electrodes are combined, and there is a high-temperature-resistant ceramic or The insulating pad made of high silica glass with positioning function makes the process of combining the two electrodes simple and short-circuit proof. The two electrodes are combined and sealed in a vacuum chamber and filled with a small amount of cesium.

Abstract

The invention relates to a cellular thermionic power generation stack that is formed by combination of a cellular plate-shaped cathode and a hexagonal plate-shaped anode; therefore, generation areas of the electrodes can be multiplied so as to improve generating efficiency. Especially, when the anode is integrated with a static mixer, not only can the anode be cooled but also fluid for regeneration can be provided to improve general generating efficiency. If the fluid for regeneration is directly discharged as injection power, investments on equipment can be reduced; and the cellular thermionic power generation stack is especially suitable for a space rocket and a water jet boat and the like.

Description

technical field [0001] The invention relates to a thermionic power generation pile, in particular to a honeycomb type thermionic power generation pile. Background technique [0002] At present, the thermionic power stacks such as nuclear or solar energy based on vacuum thermionic power generation diodes have the disadvantage that the electrode surface area is small and the power generation efficiency is low. For example, the efficiency of nuclear thermionic power stacks for nuclear submarines is only about 6%. Contents of the invention [0003] The object of the present invention is to provide a honeycomb thermionic generator pile, which has high power generation efficiency, is easy to manufacture and has wide application. [0004] To achieve the above object, the honeycomb thermionic power stack of the present invention is composed of a honeycomb plate-shaped cathode and a corresponding pair of hexagonal nail-plate-shaped anodes. [0005] With such a structure, not only ...
