1, cooling capacity
That is, the cooling capacity of the chiller. According to the photoelectric conversion efficiency of the laser equipment to calculate the amount of heat generated, and then paired to select the appropriate industrial chiller. Different types of chiller in this regard will also exist in different ways, users can be calculated through a number of different ways to rationalize the choice.
2, temperature control accuracy
This indicator comes entirely from the requirements of the laser, for semiconductor lasers must be temperature control accuracy of ± 0.1 ℃, which requires the compressor to predict the pattern of change in temperature, adaptive load changes, generally with the integration of temperature control module of the water cooler is not possible to do this. Of course, in terms of CO2 laser temperature requirements ± 2 ℃ to ± 5 ℃, most of the specialized water coolers on the market can do.
3, water flow and booster pump head
Refrigeration capacity on behalf of the compressor can provide refrigeration capacity, while the water flow on behalf of the chiller to take away the heat of the ability to cause the phenomenon we often see: nominal refrigeration capacity of 1,000W chiller connected to an 80W glass tube, the chiller shows 25 ℃, the laser tube but the heat of the hot; in fact, did not play a role in the application of the Role.
4, thermal efficiency and water volume
In general, the water tank is the bigger the better, but in the design of different compressor control will be very different. This is the same compressor refrigeration capacity and water volume, with PID feedback function of the operation control will greatly improve the overall system cooling capacity.
5, water quality requirements and water filtration and water circulation system material
This comprehensive indicator is often ignored, but its very heavy use, directly affecting the life of the laser. Like a lot of filterless is the chiller directly add tap water or use a long time without replacement of pure water, will make the breeding of bacteria and impurities deposited into the laser, affecting the life of the laser and the use of the effect.
