Laser chillers are commonly used for cooling laser devices such as cutting machines, marking machines, and engraving machines, especially for CO2 laser glass tubes, semiconductor lasers, or fiber lasers.
During long-term operation, laser generators continuously produce heat, leading to a constant rise in temperature. Excessive temperatures can affect the normal operation of the laser generator, so laser chillers are required to perform water circulation cooling and temperature control.
The laser chiller is a specialized application of industrial chiller in the laser industry. The primary purpose of a laser chiller is to perform water circulation cooling for the laser generator and control its operating temperature, ensuring that the laser generator remains in normal working condition for extended periods.
When selecting a chiller for a laser device, it is advisable to choose one that can monitor process values such as water temperature, pressure, and flow rate, and has interlock protection with the laser. The internal safety protection and remote control of the chiller are closely related to the safe operation of the laser.
Depending on the type of laser generator, the laser chiller can be categorized into CO2 glass laser tube laser chillers, CO2 metal RF tube laser chillers, semiconductor side-pumped laser chillers, semiconductor end-pumped laser chillers, YAG laser chillers, fiber laser chillers, and UV laser chillers.
The cooling capacity of the chiller unit is a key indicator for selecting a chiller. Users can calculate the heat generated by the laser based on its different power levels and then select the appropriate chiller. The heat generated by the laser can be calculated according to its laser power.
Calculation Formula: P_heat = P_laser * (1-η) / η
P_heat: represents the heat generated by the laser (W);
P_laser: represents the laser output power (W);
η: laser electro-optical conversion efficiency (%), depending on the specific laser.
Range of values for electro-optical conversion efficiency η
CO2 laser: 8-10%
Lamp-pumped laser: 2-3%
Semiconductor-pumped laser: 30-40%
Fiber laser: 30-40%
For example: If a CO2 laser has an output power of 800W and an electro-optical conversion efficiency of 8.5%
P_heat = 800 * (1-8.5%) / 8.5% = 8612W
The cooling capacity of the industrial chiller should be greater than the heat generated, allowing you to select the chiller that meets your needs.
