Abstract
The utility model discloses an efficient high-voltage etcher with uniform fluid distribution and forced degasification functions. The etcher comprises an aluminium foil, an etching tank, electrodes, conducting rollers, driving rollers, acid spraying boxes, acid spraying holes, circulating pumps, circulating pipes and flowmeters, wherein the electrodes are arranged in the etching tank; etching liquid is filled in the etching tank; the acid spraying boxes are fixed at the bottoms of the electrodes and fully immersed in the etching liquid; and acid spraying holes are formed on the upper surfaces of the acid spraying boxes. As etching holes on the surface of the aluminium foil are highly dense and uniformly distributed, have almost the same size, and are cylindrical, an aluminium matrix has clear boundary and appropriate thickness, and the etching depth has better consistency, the effective surface area of the aluminium foil is further increased, that is, the aluminium foil has an improved capacity and better consistency in both capacity and strength.
