Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of laser cutting machines, in particular to a heat dissipation device for laser cutting machines. Background Art

[0002] Laser cutting machines focus the laser light emitted from a laser into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach a melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. The existing laser cutting machines need to dissipate heat and cool down when working.

[0003] However, the prior art lacks the function of maintaining a constant temperature and cooling the laser cutting machine. In actual use, the laser cutting machine will emit a large amount of heat energy during use. Failure to continuously cool down the machine will cause the laser cutting machine to be unusable and cause damage to parts. The prior art uses a cold water immersion method for cooling. Long-term immersion will cause the cold water to become hot, and the water needs to be changed to cool the cutting machine. Frequent water changes are cumbersome, which leads to limitations in the prior art. The prior art also lacks the function of cleaning the filter. In actual use, after water cooling, the water needs to be recycled for secondary use. The prior art water will take away some impurities and dirt on the surface of the laser cutting machine during cooling when it flows back. The filter will usually filter it. After a long period of filtration, impurities will block the filter port, resulting in the inability of water to circulate quickly, causing blockage. Utility Model Content
