Electromagnetic shape correcting device and method for ultrathin micro-channel plate

Abstract

The invention belongs to the technical field of manufacturing of complex micro-channels of ultra-thin plates, and particularly relates to an electromagnetic shape correcting device and method for ultra-thin micro-channel plates. The device comprises an electromagnetic coil module, a shape correcting module and a power supply module, the electromagnetic coil module comprises a hollow background magnetic field coil, and the shape correcting module is arranged in the hollow position of the interior of the background magnetic field coil; the power supply module comprises a first pulse power supply and a second pulse power supply, during use, the first pulse power supply and the second pulse power supply discharge electricity to the background magnetic field coil and the ultra-thin micro-channel plate to be shaped respectively, and the ultra-thin micro-channel plate to be shaped is firstly heated to realize rapid annealing treatment with instantaneous temperature rise; and then pulse electromagnetic force is generated under the combined action of pulse current in the ultra-thin micro-channel plate to be shaped and a pulse magnetic field generated in the background magnetic field coil, the ultra-thin micro-channel plate to be shaped is driven to rush to the mold, and shaping of the micro-channel plate is achieved.

Description

technical field [0001] The invention belongs to the technical field of complex microchannel manufacturing of ultrathin plates, and more specifically relates to an electromagnetic shape correction device and method for ultrathin microchannel plates. Background technique [0002] With the development of miniaturization of components in the manufacturing industry, the processing technology of micro and complex structures has been developed rapidly. Ultra-thin microchannel plate is a typical fine and complex structure, which has multiple functions such as conducting medium and exchanging heat. It is often used in bipolar plates of fuel cells and high-efficiency heat exchangers in equipment heat transfer systems. Ultra-thin micro-channel plates are usually made of metal materials with a thickness of 50-100 μm, and have tens to hundreds of micro-channels with a groove width and depth less than 1 mm. The size effect brought about by the fine structure makes the processing of ultra-...
