Description

Technical Field

[0001] The invention relates to a novel refrigeration system for a solid laser welding machine. Background Art

[0002] Solid-state laser welding machines generally use xenon lamps as pump light sources. During operation, the xenon lamp discharges pulses to the laser rod at a certain frequency. When the xenon lamp discharges, a large amount of heat is generated in the laser's focusing cavity, and the xenon lamp and laser rod need to be cooled. The cooling method currently used in the industry is mainly to cool the focusing cavity by connecting a chiller to the outside. Since the chiller is large in size and needs to be placed in a separate space, the direct result is that the overall equipment occupies a large area, and the storage and transportation costs are high. Summary of the invention

[0003] The purpose of the present invention is to solve the above deficiencies in the prior art and to provide a new refrigeration system for a solid laser welding machine that is easy to connect.
