Industrial Laser

Industrial lasers are used in a wide range of applications. While in sectors like laser cutting, welding, and optical systems, a concentrated laser beam has the potential to produce substantial heat. The lasers with high power capabilities can generate over 10,000 Watts of energy when used on thick metals. Fluctuations in temperature can alter the laser wavelength as it travels through the optics, leading to inefficiencies that may manifest as subpar welds or sputtering.

Addressing Thermal Challenges with Precision

In industrial laser and optical systems, maintaining thermal stability is non-negotiable for consistent performance and product quality. Here’s how spot cooling addresses some common thermal challenges:

Localized Heat Management: Spot cooling enables precise targeting of heat-intensive areas within a system, such as laser diodes, focusing lenses, and optical sensors. By effectively dissipating heat at these critical points, spot cooling prevents overheating, minimizes thermal drift, and preserves the integrity of sensitive components.

Thermal Uniformity: In applications where uniform temperature distribution is crucial for optimal performance, spot cooling ensures thermal equilibrium across the system. By regulating temperatures with precision, spot cooling eliminates hotspots and cold zones, thereby enhancing process repeatability and accuracy.

Compact Design Integration: The compact form factor of liquid cooling units makes them ideal for integration into space-constrained industrial environments. Whether retrofitting existing systems or designing new installations, spot cooling units offer flexibility and scalability without compromising operational efficiency.

Energy Efficiency: By targeting cooling efforts only where necessary, spot cooling minimizes energy consumption compared to traditional cooling methods. This energy-efficient approach not only reduces operational costs but also aligns with sustainability initiatives by conserving resources and reducing carbon footprint.

However, the increasing trend of higher laser power in smaller packages can be a new challenge. Reducing the space requirements in production floors, clinics, medical operating rooms, and laboratories, puts the product manager under pressure to shrink the size of external laser chillers while still producing peak performance and energy efficiency. The widespread TEC technology offers compactness in size yet faces limitations of cooling capacity and energy saving for high-power lasers and optical components. Some engineers are considering integrating the refrigeration system directly into their system to create a more compact package, making decisions early in the concept development.

Moir Cooling, an experienced manufacturer and supplier of miniaturized vapor compression technology, is one of those, who constantly explores new tech solutions to capture the changing market. Our compact liquid cooling unit is the breakthrough result of the innovation activity. The compact liquid cooler utilized our advanced variable-speed inverter, twin-cylinder pumps, and miniature compressor, providing the highest capacity for the laser equipment in the smallest space.

Eco-friendly: This small, robust and eco-friendly DC cooling unit applies natural R290 as a refrigerant, a non-toxic gas with zero ODP and very low GWP, has no impact the environment.

The thermal system is used to decrease the heat load generated by the laser procedures. The chiller is small, yet it can have a high cooling capacity of up to 800 watts. It can cool well below ambient temperature and actively remove heat from sensitive electronics. Compressor-based water chillers for laser cooling often have a high heat pumping capacity density per square to match the heat generated by the laser. With a hermetic configuration, our mini liquid chiller significantly reduces maintenance and total ownership costs. The liquid chiller only provides the core refrigeration components(compressor, condenser, expansion, capillary, evaporator), allowing the integrator to adapt to their system for ultimate flexibility. Plus, the small laser chiller offers high reliability, reduced operation noises, and performs well in high-vibration applications.

MOIR isn’t just a miniature cooling solution manufacturer and supplier, we’re your trustworthy partner in pushing the boundaries of industrial laser technology where compactness and reliability are parameters.
