Laser chiller

优势及用途：Laser source in the laser system,both the light pencil controller and the electric control box need the extra cooling.requirements of freezing water temperature are usually between 15~22 ℃, the requirement of frozen water precision are usually 1K or ± 2K ±. Part of the equipment may require ± 0.5K, another part of the equipment requirement of freezing water conductivity, corrosion resistance etc.Usually startup laser system it have requirement of the water temperature , so that it need to increase the electric heating in water loop. The beam controller in the part of the system will require separate cooling circuit. For special applications in laser systems, are specifically designed industrial chiller to meet the different require .

Most users and manufacturers in the selection and recommendation of laser cooling systems are often with very vague conception, there are lots of laser chillers in the market are  also have no clear quota, the consumers choose equipment are also drift with the current, not accurately protect laser equipment in the resonable .  belows are several indexes of the mentioned on choice laser cooling water machine are important .

1、refrigerating capacity ，as the term suggests is the Actual cooling capacity of the refrigerating equipment,it's the frist indexes of choice laser cooling equipment .

Commonly ,we can figure out the laser's heating power rely on the laser photoelectric transformation efficiency ,then choose the chiller.P heat=P laser/μ,suppose the glass tube CO2 laser heat efficiency is 15%,the laser in 80W need the heating power at least 80/0.15=533W,that is to say,in the production student 80W laser at the same time, laser injection 533W energy, ineffective energy need taken away by the laser chillers。Sometimes we directly according to  the laser rate input power subtracting laser output power to confirm the refrigerating output of the laser chiller.For example,the RF and solid state lasers we usually used will be marked with rated full power voltage ,for example ,the coherent70W RF, the power input  is 48V25A, instantaneous current is 36A,we can figure out the maximum input power is 1200W.

2、Selection of water flow and pump discharge.We will focus on the cooling capacity,often ignore the index of water flow.  refrigeration capacity represent the refrigeration ability of the copressor ,but the water discharge represent the ability of compressor to take away the heat,this has caused the phenomenon that people often had see:The nominal system Chiller cooling capacity of 1000W connect to a 80W glass tube, the chiller display 25 ℃ ,but Laser tube is hot, in the fact it hasn't to be done .

3、Thermal efficiency and water volume.This two concept leads to the concept of chiller thermal efficiency and water cubage, it is two index  of the compressorcontrol Method and the tank size  .Generally water tank  the bigger the better, but different on design of compressor control methods will be different. This is the same compression refrigerating capacity and water cubage, with the operation control mode of PID feedback function will greatly enhance the cooling capacity of the overall system .
