Abstract
A reflecting mirror lens radiator of a carbon dioxide laser tube is characterized in that a fan is arranged at the reflecting mirror end of the carbon dioxide laser tube on the mounting stander of the carbon dioxide laser tube. The utility model overcomes the defects in the prior art that the glass material adopted in the water cooling way is high borosilicate glass which has low breakdown voltage and is easy to result in discharging to the water flow in electronegative potential, thereby forming the hidden danger of insecurity of laser equipment; in addition, the plate-fin passive radiating way is very easy to influence the radiating effect due to conditions of the laser equipment, such as ventilation, and the like. The radiating of the utility model belongs to an active radiating way and is little affected by the environment, and the radiating effect is better. The fan is additionally provided with cooling equipment so that a carbon dioxide laser reflecting mirror works in an invariable temperature range, and the service life and the reliability of the carbon dioxide laser tube are further improved.
Description
Technical field
The utility model relates to a kind of cooling device of laser, is a kind of radiator for reflective lens of carbon dioxide laser tube specifically, is applied to the heat radiation of glass or quartzy material continuous current excitation enclosed type or half sealed CO 2 laser tube.
Background technology
In traditional CO 2 laser tube, completely reflecting mirror generally is to be substrate with materials such as glass, quartz, silicon or copper, plates gold, silver or amplified medium reflectance coating through surface of polished with vacuum coating method.Perfect condition is that the reflectivity of reflectance coating is 100% reflection fully.But owing to the reflectivity of well-known reason reflectance coating can only reach 98%-99.5%.The rising that the temperature of speculum can continue in CO 2 laser tube work like this seriously influences the useful life and the reliability of CO 2 laser tube.Traditional method is that the oil cooling cover of pasting a glass water collar or metal on speculum dispels the heat to speculum.Wherein metal oil cooling cover is owing to need other structures such as oil pump, and complex structure has increased the volume of laser equipment again, therefore adopts the glass water collar to cool off reflecting optics usually.Water collar is located on the reflecting optics, takes away heat on the reflecting optics, can play cooling effect by the water that flows in the water collar.But because near the electrode tip region of discharge the reflecting optics has 20000-30000 volts high voltage, and the glass material that adopts at present is a high-boron-silicon glass, as homemade GG-17, and 95 material glass etc.The puncture voltage of this class material is lower, is easy to cause the current to being in electronegative potential to discharge.Thereby form the hidden danger of laser equipment.
China utility model patent specification CN201018182Y provide a kind of CO on February 6th, 2008
2Laser tube reflecting optics radiator, its heat abstractor are fin.The heat radiation type radiating mode belongs to passive radiating mode, and after CO 2 laser tube was contained in the laser equipment, being easy to influenced radiating effect because of condition restriction such as laser equipment ventilations
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of radiator for reflective lens of carbon dioxide laser tube of little, better heat-radiation effect affected by environment, and the utility model can overcome the potential safety hazard that exists when using traditional water collar, easily manufactured.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: on the frame of CO 2 laser tube fan is installed, fan is positioned at CO 2 laser tube speculum end.
Can install refrigeration plant additional on the said fan of the utility model.
The utility model can overcome the potential safety hazard when using water collar owing to adopted technique scheme under the prerequisite that effectively reduces mirror temperature.Heat radiation of the present utility model belongs to the mode of active heat removal, and is affected by environment little, better heat-radiation effect.Install refrigeration plant on fan additional, the easier carbon dioxide laser speculum that makes is operated in the stationary temperature scope, further improves the useful life and the reliability of CO 2 laser tube.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
In the accompanying drawing, CO 2 laser tube 1 is contained in the frame 2, is fixed on the support 3,4 of frame, and the speculum 5 of CO 2 laser tube 1 is naked state, not additional any heat radiation cooling device on the speculum 5.On the casing 2 that CO 2 laser tube speculum 5 directions are housed, install 6 pairs of heating speculums of the small and exquisite fan of high air quantity volume 5 additional and carry out forced cooling.Can on fan 6, install refrigeration plant additional and further improve refrigeration.7 are depicted as fan 6 airflow directions; 8 are depicted as the outbound course of CO 2 laser tube 1.
