How to Choose a Suitable Chiller According to the Power of the Laser?

The general selection rule is that the cooling capacity of the chiller is greater than the heat generation of the laser equipment. But because there are many types of lasers, such as solid-state lasers, gas lasers, etc., the matching rules of different lasers are different, and it is also necessary to combine the cooling capacity, temperature control accuracy, and water pump of each laser chiller. Flow head and other technical parameters.

To match the chiller according to the power of the laser, please refer to the following aspects for details:

1. Cooling capacity

That is, the cooling capacity of the chiller. According to the photoelectric conversion efficiency of the laser equipment, calculate the calorific value generated by it, and then match and select the appropriate chiller. Different types of chillers will also be different in this aspect. If you don’t know much about this aspect, welcome to consult us.

2. Temperature control accuracy

This indicator is completely derived from the requirements of the laser. For semiconductor lasers, the temperature control accuracy must be ±0.1°C. This requires the compressor to predict the temperature change law and adapt to the load change. Generally, it is impossible to use a water cooler with an integrated temperature control module. to this point. Of course, for CO2 lasers, the temperature requirement is ±2°C to ±5°C, which can be achieved by most special water coolers on the market. However, our chiller brand is currently one of the few laser chillers that can truly reach ±0.1°C.

3. Water flow and booster pump head

The cooling capacity represents the cooling capacity provided by the compressor, and the water flow represents the ability of the chiller to take away heat. It shows 25°C, but the laser tube is so hot that it doesn’t work in fact.
