Description
Technical field
The utility model relates to carbon dioxide laser device, particularly a kind of radiator of the band radiating fin for carbon dioxide laser reflecting optics.
Background technology
Carbon dioxide laser is the gas laser using carbon dioxide as operation material, and discharge tube is normally made up of glass or quartz material, and the inside is filled with carbon dioxide and other assist gass; Electrode is generally nickel hollow cylinder; One end of resonant cavity is reflecting optics, and the other end is output optic acts.When high voltage on electrode, in discharge tube, produce glow discharge, after output optic acts and reflecting optics reflect, form laser beam.Carbon dioxide laser has larger power and higher energy conversion efficiency, and spectral line is also abundanter, has the Laser output of tens spectral lines near 10 microns, is widely used in industry, military affairs, medical treatment, scientific research etc.
In use, electrode applies high voltage, current carbon dioxide laser only has portion of energy to be converted when there is laser, all the other power conversion are the heat energy of gas, elevate the temperature, and the rising of gas temperature, will disappearing of upper laser level be caused to excite the thermal excitation with laser lower level, this all can make the inverted population of particle reduce; Further, the rising of gas temperature, will make broadening of spectral lines, cause gain coefficient to decline; Particularly, the rising of gas temperature, also will cause the decomposition of carbon dioxide molecule, and reduce the carbon dioxide molecule concentration in discharge tube, these factors all can make the power output of laser decline, and even produce " temperature quenching ".
In order to reduce the temperature of laser, be that sheathed cooling water pipe, to reduce the temperature of discharge tube, the reflecting optics and output optic acts at laser two ends arranges coolant jacket to cool the temperature of reflecting optics and output optic acts outside discharge tube at present.
The coolant jacket of current use, its structure has the cavity that is held cooling fluid, coolant jacket is provided with the import and outlet that are communicated with cavity, in use, import and outlet are connected with external refrigeration liquid, cooling fluid in coolant jacket cavity and external refrigeration liquid are circulated, and then realizes the cooling to reflecting optics and output optic acts.
But, the coolant jacket of above-mentioned this structure, due to be adopt cooling fluid dispel the heat, after coolant jacket is installed, the sealing of cooling fluid cavity is particularly important, if gap appears in cavity sealing, cooling fluid flows out, and the negative electrode of laser and positive electrode are all high-voltage state, so easily make negative electrode or positive electrode, to water cooling tube electric discharge, security incident occur.But, because the material itself of reflecting optics, output optic acts, cylinder and these structures of coolant jacket is different, and in use, these structure self-temperatures raise also not identical, so when expanding with heat and contract with cold, change in size is each other also inconsistent, so cause extremely easily being opened between structure occurring crack, causes coolant jacket to leak.
So, need a kind of coolant jacket for carbon dioxide laser that cooling fluid can be avoided to leak at present badly.
Utility model content
The purpose of this utility model is: for the coolant jacket above shortcomings of existing carbon dioxide laser output optic acts, provides a kind of reflecting optics coolant jacket that cooling fluid can be avoided to leak.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of radiator of the band radiating fin for carbon dioxide laser reflecting optics, include sheath body and some fins be disposed on described sheath body outer wall, described sheath body open at one end and the other end is closed, the described inwall of sheath body closed end matches with the reflecting optics of carbon dioxide laser.Reflecting optics is arranged in sheath body, be arranged on the end of cylinder again, owing to being arranged at intervals with some fins on sheath body outer wall, heat on reflecting optics is delivered on sheath body and fin and carries out heat exchange with extraneous air, realizes the cooling to reflecting optics, cools owing to not adopting cooling fluid, so when installation, do not need to consider the sealing to cooling fluid, so reduce installation difficulty, directly avoid the adverse effect brought due to cooling fluid leakage simultaneously yet.
As preferably, the inwall of described cover shell side wall coordinates with the sidewall spacers of described reflecting optics.Because reflecting optics and sheath body are when temperature changes, can there is certain change in size own, so sheath body inwall sidewall circumferentially coordinates with reflecting optics sidewall spacers circumferentially, avoids extruding when expanding with heat and contract with cold between reflecting optics and sheath body.
As preferably, the sidewall of described sheath body exceeds described reflecting optics and the matching ends of cylinder with carbon dioxide laser.The sidewall of sheath body and the matching ends of cylinder, make reflecting optics be arranged on cylinder by sheath body, avoid reflecting optics to be arranged on cylinder end, and born the weight of radiator by eyeglass, ensure that the reliability that reflecting optics and sheath body are installed; Further, in installation process, first reflecting optics can be arranged in sheath body, and then sheath body is arranged on the end of cylinder, after the precision of first accommodation reflex eyeglass and output optic acts, then fix sheath body, ensure installation accuracy so also convenient.
As preferably, the inwall of described shroud base is provided with the projection matched with described reflecting optics.Because laser is precision instrument, in production installation process, required precision is high, the particularly installation accuracy of reflecting optics and output optic acts, so need to ensure that the position of shroud base installation reflecting optics has higher precision, so by arranging the projection matched with reflecting optics, only needing to ensure protruding end face precision, facilitating production and processing.
As preferably, described sheath body and fin are integral type structure.Sheath body and fin are integral type structure, and its heat conductivility is guaranteed, and then ensure the heat-sinking capability of radiator.
As preferably, described sheath body and fin are ceramic material.Because reflecting optics is positioned at the high-pressure side of laser, and ceramic material has good insulation, high pressure resistant wait excellent properties, avoid laser to external discharge.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, the adverse effect brought due to cooling fluid leakage is directly avoided;
2, easy for installation.
