Abstract
The utility model relates to a carbon dioxide laser device, and especially relates to a carbon dioxide laser reflection end cooling jacket, comprising a housing. One end of the housing is provided with an opening. The end of the opening of the housing is provided with a conducting strip. The conducting strip and the housing cooperate to form a closed cooling liquid storage cavity. The housing is provided with a water inlet and a water outlet communicated with the cooling liquid storage cavity. One end of the conducting strip is a first matching surface matching with the end of the housing opening, and the other end is a second matching surface matching with a reflector of a carbon dioxide laser. Outer edges of the second matching surface of the conducting strip extend outward and exceed the housing to form a wing edge. Since the wing edge is arranged, and the wing edge exceeds the housing, junctures between the conducting strip and the housing are blocked by the wing edge, so when a gap is between the housing and the conducting strip, difficulty of discharging of the electrode for the housing is increased because of blocking of the wing edge, so that risks that the electrode discharges for the cooling jacket are reduced.
Description
Technical field
The utility model relates to carbon dioxide laser device, particularly carbon dioxide laser reflection end coolant jacket.
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 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 mirror-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, is widely used at aspects such as industry, military affairs, medical treatment, scientific researches.
In use, on electrode, apply high voltage, current carbon dioxide laser only has portion of energy to be converted in the time 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 and the thermal excitation of 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, is at present the temperature that sheathed cooling water pipe reduces discharge tube discharge tube outside, on the reflecting optics at laser two ends and output eyeglass, the cooling reflecting optics of coolant jacket is set and exports the temperature of eyeglass.
The coolant jacket using is at present generally two kinds of structures, one is with glass or the integrated water collar of metal material, due to this integral type water-cooled cover processing difficulty, the factors such as production efficiency is low, so on market out the water collar of split-type structural, the structure of Split type water-cooling cover is generally and the conducting strip of eyeglass laminating and the cooling sheath body being tightly connected with conducting strip, cooling sheath body is formed cooling fluid storage by conducting strip sealing and receives chamber, although adopt the water collar of split-type structural to solve processing difficulties, the problem that production efficiency is low, but find in actual use, because conducting strip is due to by heating repeatedly, due to the reason of expanding with heat and contract with cold, in use for some time, easily there is gap and leak in the seam between conducting strip and cooling sheath body, electrode is discharged to coolant jacket, cause leaky, not only affect the quality of laser Output of laser, also brought potential safety hazard.
So, need at present one badly and facilitate processing, can prevent again the carbon dioxide laser coolant jacket of electrode to coolant jacket electric discharge.

As preferably, between described water inlet pipe and outlet pipe, on the inwall of corresponding described sheath body, be provided with dividing plate.Cooling fluid enters by water inlet pipe in the cavity of sheath body, due to the dividing plate arranging between water inlet pipe and outlet pipe, avoid cooling fluid directly to flow out from outlet pipe, just flow out from outlet pipe but flow to walk around after dividing plate along sheath body inwall, increase the mobile length of cooling fluid in sheath body, improved the cooling effect of cooling fluid.
As preferably, on the end of described cover shell opener, be provided with the first groove, the position that described wing rafter is corresponding with described the first groove is provided with projection, and described projection matches with described the first groove.Projection matches with the first groove, improve the fastness being connected between conducting strip and sheath body, and, owing to being provided with the first groove, in the time of assembling, can directly fluid sealant be coated in the first groove, when having facilitated the coating of fluid sealant, also improve sealing effectiveness, further reduce the risk of electrode pair coolant jacket electric discharge.
As preferably, in described the first groove, be provided with the second groove.When apply fluid sealant in the first groove, after projection is placed in the first groove, the part fluid sealant being coated in the first groove is pressed into the second groove, the O-ring seal that forms whole ring-type in the second groove, makes, even in the situation that expanding with heat and contract with cold, between projection and the first recess sidewall, may form gap, but due to the existence of O-ring seal, gap is cut off, so still can play good sealing effectiveness.
As preferably, described conducting strip, wing rafter and projection are integral type structure.Conducting strip, wing rafter and projection are set to integral structure, have reduced the connection gap between each member, avoid leaking occurring, and convenient processing and production.
As preferably, described sheath body is resin material.Make the sheath body can be one-body molded, realize mass production, enhance productivity, simultaneously because resin material has certain elasticity, in the time expanding with heat and contract with cold, can deformation together occur with conducting strip, further avoid occurring gap between conducting strip and sheath body.
As preferably, described conducting strip, wing rafter and projection are ceramic material.Ceramic material has good pyroconductivity, has ensured the cooling effect to reflecting optics, and meanwhile, ceramic material has less coefficient of thermal expansion, also further avoids occurring gap between conducting strip and sheath body.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
Owing to being provided with wing rafter on conducting strip, wing rafter exceeds sheath body, namely make the seam between conducting strip and sheath body be blocked by wing rafter, so, in the time occurring between sheath body and conducting strip that gap cooling fluid flows out, due to stopping of wing rafter, increase the difficulty of electrode pair sheath body electric discharge, also just reduce the risk of electrode pair coolant jacket electric discharge.
