Embodiment
The overall structure of the present embodiment as shown in Figure 2 and Figure 4, fiber coupling module, TEC power supplys, in water-cooling system whole
Put in the equipment of rear end, drawn optical fiber, TEC power lines, water pipe by protection sleeve pipe, and have with the laser medicine hand of front end
Connection.
First, light source
There is hot spot uniformity is good, pliability is good etc. as treatment light source, fiber coupling module using fiber coupling module
Advantage, and fiber coupling module and laser medicine hand tool separate in such a system, thus laser medicine hand tool with small volume,
The features such as in light weight, anti-condensation.
2nd, water circulation system
Circulating water structure part structure built in hand tool, is made up of water inlet, water outlet and water tank, and is sealed using O circles, water
The purpose of box structure is radiated for TEC, and this structure has the characteristics of radiating efficiency is high, stability is good, as shown in Figure 7.
3rd, refrigeration system
Refrigeration component employed in refrigeration system is annular TEC, as shown in figure 8, this TEC structure is exclusively for this
Device and design, there is the characteristics of high cooling efficiency, stability strong, good reliability.TEC is that the refrigeration head of front end is freezed.
TEC caused heats in refrigeration are radiated by the cisten mechanism of rear end, finally realize system stabilization, Effec-tive Function,
Specific such as Fig. 6, shown in 7：For cooling circulating water by the hot-side heat dissipation that water tank is TEC, TEC cold end is refrigeration head and fiber waveguide system
It is cold, treatment when can ensure there is relatively low temperature, reduce treatment caused by pain, while the recirculated water of water tank can and
When take away TEC hot junctions caused by heat, enable the work of TEC efficient stables.
The operation principle of semiconductor cooler (TEC)：
Semiconductor cooler is also known as TEC, connects two blocks of different metals with conductor, connects direct current, then a junction
Temperature reduces, the rise of another junction temperature.If by reverse power connection, the temperature inverse variation of junction.This phenomenon claims
For peltier effect, also known as thermo-electrically effect.The thermo-electrically effect very little of simple metal, if with a N-type semiconductor and a p-type partly
Conductor replaces metal, and effect is with regard to much bigger.After switching on power, upper contact nearby produces electron-hole pair, and interior energy reduces, temperature
Reduce, outwardly absorb heat, referred to as cold end.The other end is because electron-hole pair is compound, interior energy increase, temperature rise, and is put to environment
Heat, referred to as hot junction.The temperature difference caused by a pair of semicondcutor thermoelements and cold all very littles, practical semiconductor cooler be by
Much thermoelectric element is formed through in parallel, tandem compound, also referred to as thermoelectric pile.The available about 60 DEG C temperature difference of single stage thermoelectric heap,
That is reachable -10~-20 DEG C of cold junction temperature.Increase thermoelectric pile series can increase the temperature difference at both ends.
4th, optical system
As shown in figure 5, laser has by the conduction of light into laser medicine hand, then the transmission Jing Guo fiber waveguide with
Homogenize final output.
Optical system uses one-part form optical waveguide structure, hot spot is more homogenized；And used in the position of contact skin
Cambered surface designs, can be more smooth in treatment.
