Description
Technical field
The utility model relates to carbon dioxide laser device, particularly a kind of radiator with radiating fin for carbon dioxide laser output eyeglass.
Background technology
Carbon dioxide laser is to using carbon dioxide as the gas laser of operation material, and discharge tube is normally made by glass or quartz material, and the inside is filled with carbon dioxide and other assist gass; Electrode is generally nickel hollow cylinder processed; One end of resonant cavity is reflecting optics, and the other end is output eyeglass.When add high voltage on electrode, in discharge tube, produce glow discharge, after output eyeglass and reflecting optics reflection, 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, at aspects such as industry, military affairs, medical treatment, scientific researches, is widely used.
In use, on electrode, apply 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 cause that disappearing of upper laser level excites the thermal excitation with laser lower level, this all can make the inverted population of particle reduce; And 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, reduces the carbon dioxide molecule concentration in discharge tube, and 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 the temperature that sheathed cooling water pipe reduces discharge tube outside discharge tube at present, the temperature of the cooling reflecting optics of coolant jacket and output eyeglass is set on the reflecting optics at laser two ends and output eyeglass.
The coolant jacket using at present, its structure has a cavity that holds cooling fluid, on coolant jacket, be provided with the import and the outlet that are communicated with cavity, in use, import and outlet and external refrigeration liquid are connected, make cooling fluid and the circulation of external refrigeration liquid in coolant jacket cavity, and then realize the cooling to reflecting optics and output eyeglass.
But, the coolant jacket of above-mentioned this structure, because being adopts cooling fluid to 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 eyeglass, 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 being extremely easily opened and occurring crack between structure, causes coolant jacket to leak.
So, need at present a kind of coolant jacket for carbon dioxide laser that can avoid cooling fluid to leak badly.
Utility model content
The purpose of this utility model is: the coolant jacket above shortcomings for existing carbon dioxide laser output eyeglass, provide a kind of output eyeglass coolant jacket that can avoid cooling fluid to leak.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of radiator with radiating fin for carbon dioxide laser output eyeglass, include sheath body and some fins being disposed on described sheath body outer wall, described sheath body is the housing that one end is opening-wide state, the mating surface of the medial surface of the other end of described sheath body for matching with the output eyeglass of carbon dioxide laser, on this end, be provided with through hole, the diameter of described through hole is less than the diameter of described output eyeglass.Output eyeglass is arranged in sheath body, be arranged on again the end of cylinder, owing to being arranged at intervals with some fins on sheath body outer wall, heat on output eyeglass is delivered on sheath body and fin and carries out heat exchange with extraneous air, realizes exporting the cooling of eyeglass, cooling owing to not adopting cooling fluid to carry out, so when installing, do not need to consider the sealing to cooling fluid, so reduced installation difficulty, directly avoided because cooling fluid is leaked the adverse effect of bringing yet simultaneously.
As preferably, the inwall of described cover shell side wall coordinates with the sidewall spacers of described output eyeglass.Because output eyeglass and sheath body are when temperature changes, can there is certain variation in size own, thus sheath body inwall along the sidewall of hoop with export the sidewall spacers of eyeglass along hoop and coordinate, avoid exporting between eyeglass and sheath body and push when expanding with heat and contract with cold.
As preferably, the sidewall of described sheath body exceeds described output eyeglass and matches with the end of the cylinder of carbon dioxide laser.The sidewall of sheath body matches with the end of cylinder, and making to export eyeglass is to be arranged on cylinder by sheath body, avoid exporting eyeglass and be arranged on cylinder end, and eyeglass bears the weight of radiator, has guaranteed the reliability that output eyeglass and sheath body are installed; And, in installation process, can be first output eyeglass be arranged in sheath body, and then sheath body be arranged on to the end of cylinder, after the precision of first accommodation reflex eyeglass and output eyeglass, more fixing sheath body, so the also convenient installation accuracy that guarantees.
As preferably, the inner wall smooth of described shroud base is smooth.Because output eyeglass is arranged on the inwall of bottom of sheath body, so the smooth degree of shroud base inwall directly affects the installation accuracy of output eyeglass.
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 guarantee the heat-sinking capability of radiator.
As preferably, the material of described sheath body and fin is aluminium.Because output eyeglass is positioned at the low-pressure end of laser, so do not need to consider the problem of insulation, adopt metallic aluminium or aluminium alloy as the material of sheath body and fin, make it have good capacity of heat transmission, improve radiating effect.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, directly avoided because cooling fluid is leaked the adverse effect of bringing;
2, easy for installation.
