Abstract

Belonging to laser technical area, the invention solves issues of not even distributed air velocity in laser discharge zone, not even distributed gas density, and unable to extend separation distance. Characters of the invention are that the structure of gas circulation closed system is composed of laser discharge zone, trapezoidal current equalizer, comby current equalizer (3)(6)(8), plate fin type heat exchange (4)(7), modular flow fan, and quadrate current equalizer (9). The invention is mainly in use for gas circulation closed system of crossing current gas laser, and for laser welding, laser cutting, and laser beam heat treatment in industry.

Description

technical field [0001] The invention relates to a closed gas circulation system of a gas flow uniform cross-flow laser, which belongs to the field of laser technology. Background technique [0002] Demonstration experiment of water Coanda effect in China Science and Technology Museum. When the flow rate of water is lower than a certain value, the water Cohesion effect is very obvious. When water flows from the thin glass round tube to the thick glass round tube, the water flows around the thick glass round tube, the center is vacuum, and the Cohesion effect is a large part of the fluid. feature. [0003] At present, there are two main types of closed gas circulation systems for uniform cross-flow lasers in China: [0004] 1. There is no current equalizer installed at the air inlet and outlet of the laser discharge area: [0005] Such as Liu Donghua, Research on Discharge Characteristics of New Needle Plate Electrode, Laser Magazine, 1995, Vol.16, NO.2 and Zha Hongkui, etc...
