Embodiment
Referring to figs. 1 through Fig. 5, the utility model carbon dioxide laser embodiment is described further.
As can be seen from Figure 1, conduction ring set 1 is arranged on the front end of gas-storing pipe 3, and negative electricity polar ring 13 is positioned at discharge tube 5 front ends, and the cooled region of cooling water pipe 4 has partly covered the position at negative electricity polar ring 13 places.Conduction ring set 1 comprises the collector ring 143 of conflicting with negative electricity polar ring 13 ends, and one end is fixedly connected on collector ring 143 and the other end is fixedly connected on the conductive pole 14 on counter flange 11, as shown in Figure 5, wherein, conductive pole 14 is arranged on collector ring 143 along the axis of counter flange 11, the fixed form here can be direct welding, as shown in Figure 2.
A preferred scheme is that conductive pole 14 is circumferentially uniformly distributed along collector ring 143, if the benefit distributing is like this to be connected with cold air in conductive pole 14, just can better give ambient gas heat exchange.
A preferred scheme is, conductive pole 14 is provided with the fin 141 radially outward distributing along counter flange 11, as shown in Figure 3, can better play like this effect with ambient gas heat exchange, and not affecting light path 17, fin 141 can be welded on conductive pole 14.
A preferred scheme is, counter flange 11 is provided with metal Fixing shrink ring 15 with conductive pole 14 connecting portions, these metal Fixing shrink ring 15 one end are fixed on counter flange 11, conductive pole 14 is located in metal Fixing shrink ring, as shown in Figure 4, metal Fixing shrink ring 15 can be also direct welding with the fixed form of counter flange 11, and metal Fixing shrink ring 15 is interior, can get out in advance the hole suitable with conductive pole 14, then conductive pole is connected with counter flange 11 through these holes, the benefit that metal Fixing shrink ring 15 is set is the stability that not only strengthens conductive pole 14, and because conductive pole 14 is located in metal Fixing shrink ring 15, metal Fixing shrink ring 15 has been equivalent to increase the heat exchange area of conductive pole 14 so, the cooling effect of lifting to ambient gas.
Its working mechanism is:
Electric current flows into external power source by negative electricity polar ring 13, collector ring 143, conductive pole 14, counter flange 11 and negative electrode lead-in wire 112 and forms loop, at this moment discharge tube 5 build-ups of luminance, light penetrates by light path 17 and the output reflector 21 that is positioned at mounting flange 2, and now negative electricity polar ring 13 can produce high temperature.
Extraneous cold air can be made by cooling tower or refrigeration machine, then by suction nozzle 121, enter air flue 111 in counter flange, first to counter flange 11, carry out cooling, then cold air enters the through hole 16 in air inlet conductive pole 144, to air inlet conductive pole 144, carry out cooling, and by air inlet conductive pole 144 with and on fin 141 to its gas around, also carry out cooling simultaneously, then cold air enters the enclosed cavity 142 in collector ring 143 again, collector ring 143 is carried out cooling time, also the amount of heat on negative electricity polar ring 13 is delivered in cold air by collector ring 143, by cold air, absorbed, the cold air that has absorbed heat enters the through hole 16 in the conductive pole 145 of giving vent to anger, now continue cooling conductive pole 145 and the gas around of giving vent to anger, thereby cold air becomes compared with hot-air, by outlet nozzle 122, lead to extraneous.
As can be seen here, by this cooling procedure, counter flange 11, conductive pole 14, collector ring 143 all by chilled air cools, so the heat of negative electricity polar ring 13 is just absorbed by cold air in leading to the transmittance process of mounting flange 2 and discharger outside, and be air due to what use, can not produce corrosion to parts.
