Laser welding equipment, as an advanced and highly efficient joining technology, is widely used in fields such as new energy, automotive manufacturing, and 3C electronics. However, as power levels continue to increase, traditional water-cooling systems often suffer from insufficient heat dissipation during high summer temperatures, leading to frequent shutdowns of laser equipment. This not only affects production schedules but also compromises product quality. In winter, antifreeze must be added, increasing maintenance costs.
Is there a cooling system that can ensure 24/7 continuous laser operation without interruption?
Direct cooling for lasers, with 30% energy savings. Leveraging a proprietary “Active · Target · Phase” refrigeration technology, the high-efficiency direct cooling system for lasers perfectly addresses the pain points of traditional cooling methods—such as bulky size, frequent shutdowns in high summer temperatures, freezing of coolant in winter, coolant leakage risks threatening equipment safety, and high maintenance labor costs associated with water-cooling systems—providing a brand-new solution for laser temperature control.
01 Beyond “Air” and “Water”: Lightweight Design and High Environmental Adaptability
Traditional water-cooling systems are bulky and heavy, occupying valuable equipment space and limiting portability and application scenarios. The direct cooling system adopts a highly integrated phase-change direct cooling technology, eliminating components such as water pumps. As a result, system volume is reduced by over 50% compared to conventional water-cooling solutions, weight is reduced by 30%, and the footprint can be controlled within 0.2 square meters—portable by a single person.
This makes it an ideal temperature control solution for handheld welding devices and mobile laser processing equipment, enabling more compact designs and easier relocation.
Using phase-change direct cooling, the refrigerant directly absorbs heat through phase transition, achieving heat exchange efficiency far superior to traditional water cooling. The system supports startup at temperatures as low as -20°C and continuous 24-hour full-load operation in extreme environments up to 60°C. This completely eliminates issues such as overheating protection or startup difficulties caused by extreme ambient temperatures, ensuring stable year-round operation.
Traditional water-cooling systems also face long-term risks of coolant leakage. Once leakage infiltrates the laser, equipment worth hundreds of thousands of RMB may be at risk of damage or scrapping. The direct cooling system adopts a fully sealed circulation design, completely eliminating coolant and thus removing leakage risks at the physical level. At the same time, it eliminates the need for periodic fluid replacement and antifreeze addition. Combined with structural optimization, total lifecycle operation and maintenance costs are expected to be reduced by approximately 45%.
02 Reaching New Peaks: Enhancing Photoelectric Conversion Efficiency
The laser direct cooling system utilizes the “Active · Target · Phase” refrigeration technology, featuring intelligent full-variable frequency control and dual-loop regulation. Based on different laser output power levels, it dynamically allocates refrigerant flow to maintain stable operation with temperature fluctuations controlled within 1°C, helping the laser operate at its optimal wavelength.
Through precise temperature control, the laser can utilize the higher-absorption 976 nm wavelength, increasing photoelectric conversion efficiency from 30% to over 42%, and improving output efficiency by more than 10%.
03 Uniform Temperature, High Efficiency, and 30% Energy Savings for Green Manufacturing
Equipped with a self-developed, laser-specific full-variable frequency compressor, the system compresses refrigerant in a way that best matches pump thermal performance, ensuring continuous and stable cooling output. Even in high-temperature environments, it can maintain uniform temperature for the pump source.
With proprietary variable-frequency compressors and full-condition adaptive algorithms, the system precisely adjusts cooling output based on real-time heat generation of the laser, enabling on-demand cooling. Test data shows that compared to traditional water-cooling solutions, it achieves up to 30% overall energy savings, significantly reducing electricity costs for users.
The system eliminates moving components such as water pumps, removing vibration impact on the laser and significantly reducing failure rates. With a highly simplified structure and high reliability, it enables true maintenance-free operation, requiring minimal human intervention throughout the equipment’s lifecycle.
