How to set the temperature of the refrigerator of the UV laser marking machine

I don't know if you have noticed that the UV laser marking machine is usually equipped with a water tank beside the work surface. This is the refrigerator, which is used to cool the UV laser marking machine and prevent the machine from being burned out due to excessive temperature. How to set the temperature of the refrigerator of the UV laser marking machine will be introduced in detail below.

Operation example

Assuming the current water temperature is 30℃, it is required to drop to 20℃, the temperature difference is 0.1℃, the operation is as follows:

Step 1: Press the 'SET' button for 5 seconds to enter the temperature setting area, and the temperature setting indicator light is on, press Press up or down to adjust the temperature to 20°C.

Step 2: After the temperature setting is completed, press the 'SET' key to enter the temperature difference setting interface, and press the up or down key to adjust the temperature difference to 0.1°C.

Step 3: After the parameters are set, the machine starts cooling after a delay of 15 seconds. When the water temperature drops to 20°C, the bypass valve starts to work. When the water temperature rises to 20.1 ℃, the bypass valve stops working, during this period, the compressor has been running.

Precautions for using the refrigerator of UV laser marking machine:

Pay attention to the set temperature of the refrigerator. Generally, in the process of use, in winter or spring, it is better for the refrigerator to work at 23-25 u200bu200b°C, which is the best temperature for the diode module; if it is in summer or autumn, due to the high outside temperature, if the refrigerator is Under normal temperature (below 23°C), the temperature difference between the inside and outside of the diode module is too large, which will easily cause condensation, which may result in no laser output, or even damage the module! At this point we should let the refrigerator work between 25-27 ℃ as well! Secondly, if the customer installs an air conditioner indoors and keeps the indoor constant temperature at 23-25°C, then we can set the refrigerator temperature to 23-25°C for the best! (Generally, the module works most stably at 23°C, but due to the consideration of other comprehensive factors such as the outside world, the set temperature of the refrigerator should be determined according to the actual situation!)
