Laser chiller is mainly for laser equipment laser generator water circulation cooling, and control the use of the laser generator temperature, so that the laser generator can be maintained for a long time to work normally. The following 258 platform editor will introduce the selection method of laser chiller.
The following are important indicators of laser chiller selection:
One, the cooling capacity of the laser chiller:
As the name suggests, the working principle of the laser chiller is the chiller tank of frozen water sent to the need for cooling of the laser machine, the laser's heat away from the laser and then back to the water tank and then through the chiller cooling cooling cycle, to achieve the role of cooling. Assuming that the thermal efficiency of glass tube CO2 laser μ general 15%, 80W laser is the minimum need: 80/0.15 = 533W
Two, laser chiller pump pressure (Young range size)
Cooling capacity of the chiller is on behalf of the compressor can produce refrigeration capacity, while the water flow rate on behalf of the chiller to take away the heat of the ability to flow of the water flow rate, it comes down to Laser chiller pump Yang Cheng pressure size of the relationship, if the pump Yang Cheng is too low (on the market some "cheap" laser chiller pump Yang Cheng or even less than 10 meters) then the water flow rate is very slow, the water tank after cooling the water can not be timely circulation to the laser, so that the heat of the laser equipment can not be timely cooling away, then this results in the cooling capacity of the compressor can produce cooling capacity, while the water flow represents the ability of the chiller to take away the heat, which is attributed to the laser chiller pump pump pressure size. Cooling away, then this results in a phenomenon that we often see: a nominal cooling capacity of 1600W laser chiller connected to a 75W semiconductor laser marking machine, the chiller shows 25 ℃, while the laser machine is hot, this is the laser chiller does not play a role in cooling.
Three, the water filter of the laser chiller
