1, laser type cold water pause methods: calculate according to the photoelectric conversion efficiency of laser laser heat
formula: P = P laser heat & middot;
（

/ 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.
