What is the proper temperature of the water cooler of the laser cutting machine? Generally, the temperature setting range is 10 ~ 35 ℃. As a necessary cooling device of laser cutting machine, the use of laser cutting machine water cooler can ensure the stable and continuous normal operation of laser cutting machine under constant temperature. The normal operating ambient temperature in the chiller room of the laser cutting machine should be controlled at about 20 ~ 30 ℃ and not more than 40 ℃. If the chiller is operated at a temperature of more than 40 ℃, it is likely to be overloaded, and the condenser and exhaust temperature of the refrigeration system will rise, which may also cause the action of the electric protector, cut off the power supply, and affect the service life of the laser chiller. When using, pay attention to keep the air inlet and outlet of the laser chiller unobstructed, and do not block the front air inlet and the rear air outlet.
