Description

Technical Field

[0001] The utility model relates to the technical field of laser tube cooling, in particular to an active cooling system for a laser tube of a laser machine tool. Background Art

[0002] The laser tube is the core component of the laser machine tool that generates lasers. It is responsible for converting electrical energy into light energy and emitting a high-intensity laser beam. It excites gases such as carbon dioxide through gas discharge or other technical means to generate lasers. The laser beam is then guided to the processing head through optical systems such as mirrors and lenses to perform operations such as cutting, welding or engraving. The laser tube generates a lot of heat during operation, so effective heat dissipation is required.

[0003] Existing laser tube cooling systems usually only dissipate heat through circulating coolant, which has limited cooling effect. When the laser tube works continuously for a long time, the cooling effect will be greatly reduced, thus affecting the normal processing work. Utility Model Content
