Laser cooling water pause type calculation method

2020/10/04
1, laser type cold water pause methods: calculate according to the photoelectric conversion efficiency of laser laser heat

formula: P = P laser heat & middot; ( 1 - n) / n

P hot: laser heat ( W)

p laser: laser power input ( W)

N: laser photoelectric conversion rate ( %) , according to different laser.

carbon dioxide laser range: 8% 10%

light pump laser scope: 2% 3%

semiconductor pump laser range: 20% 30%

optical fibers laser range: 20% 30%

for example, some brand carbon dioxide output power of 2000 w, 2000 w laser photoelectric conversion rate of 8. 5%

P = 2000 * (hot 1 - 8. 5%) ÷ 8. 5% = 2000 * 10. 8 = 21530 w

the refrigerating capacity of the cooling water machine for laser should be greater than the calorific value, you can refer to choose TF - LS - 23 kw cooling water machine for laser.
