This 700W single-disk fiber liquid cold plate is specially developed for 700W single-disk fiber lasers. It supports the gain fiber coil and pump source components, timely removing heat generated during laser operation, regulating the operating temperature of optical fiber and pump sources, suppressing thermal distortion, and securing long-term stability of laser power and beam quality.

 

Two manufacturing options are available: embedded copper-tube aluminum liquid cold plate and integrated cavity-type liquid cold plate. Substrate outline, fiber winding area, mounting hole positions and inlet/outlet ports can all be customized according to the laser housing structure. The flow channel is optimized via CFD thermal simulation to deliver low flow resistance and uniform surface temperature, eliminating local hot spots and accommodating long-term continuous operation of fiber laser equipment.

 

 

✅ Precise Temperature Uniformity to Protect Optical Components Adopting a simulation-optimized serpentine flow channel design, it achieves excellent temperature difference control on the plate surface. It prevents local fiber overheating and thermal lens effect, enables long-duration continuous laser emission for the 700W laser without beam quality drift, and extends the service life of pump sources and gain fiber.

 

✅ Two Process Options for Selection on Demand Embedded copper tube version: Seamless oxygen-free copper tubes embedded in aluminum plate, featuring high pressure resistance and low leakage risk, ideal for high-pressure and non-stop laser equipment. Cavity-type version: Integrally milled and brazed aluminum substrate with larger heat exchange area, superior surface temperature uniformity and lighter overall weight.

 

✅ Low Flow Resistance Design to Reduce Chiller Load The flow path is specially optimized for low pressure drop, cutting power consumption of the circulating water pump and lowering total energy consumption of the whole temperature control system.

 

✅ Precision Substrate Machining for High Assembly Fitting Fabricated by precision CNC milling. The flatness of fiber winding surface is strictly controlled. Pre-machined fiber limiting grooves, module mounting holes and locating pin holes enable easy alignment and tight fitting during assembly, reducing interfacial thermal resistance.

 

✅ Rigorous Leak Detection for Long-Term Reliable Operation Every finished unit undergoes hydrostatic pressure holding test and helium leak inspection to guarantee zero leakage. Optional anodizing anti-corrosion surface treatment. Compatible with deionized water and ethylene glycol coolant for rust and corrosion protection.

 

✅ Non-Standard Customization & Rapid Sampling Customization of outline, flow channel and connector specifications based on laser internal structure, fiber coil dimension and heat source distribution. Support for prototype validation, small-batch trial production and mass production.
