High-Power Fiber Laser Water-Cooled Plate Heat Sinks

In the continuous advancement of modern high-power fiber laser technology, thermal management has become a critical issue. To ensure the stability and longevity of lasers under high-power operating conditions, the design and material selection of the cooling system are particularly important. In recent years, water-cooled plate heat sinks have emerged as a mainstream solution due to their excellent cooling performance and advanced manufacturing processes.

 

Water-Cooled Plate Heat Sink Processes and Materials

 

The core of a water-cooled plate heat sink lies in its precise manufacturing processes and high-performance material selection. Generally, a water-cooled plate heat sink consists of several key components: the cooling plate, fluid channels, heat dissipation interfaces, and connecting pipelines.

 

1. Cooling Plate Materials

 

The cooling plate is typically made from materials with high thermal conductivity, such as copper or aluminum alloys. Copper is widely used in high-power fiber laser heat sinks due to its excellent thermal conductivity and high corrosion resistance. Copper quickly transfers heat from the laser components to the cooling liquid, ensuring efficient heat dissipation. Aluminum alloys are also used in applications where weight is a critical factor, due to their light weight and good thermal performance.

 

2. Fluid Channel Design

 

The design of the fluid channels is one of the key factors affecting the performance of the water-cooled plate heat sink. Modern water-cooled plates use microchannel technology, which significantly enhances the efficiency of the cooling liquid flow and improves heat removal capability. The size and layout of the microchannels are usually carefully calculated and optimized to ensure uniform distribution of the cooling liquid over the heat dissipation area, achieving optimal cooling performance.

 

3. Heat Dissipation Interfaces

 

The heat dissipation interface needs to have excellent thermal contact performance. High thermal conductivity silicone or thermal grease is commonly used at the interface to reduce thermal resistance and ensure smooth heat transfer between the laser and the cooling plate. These materials must have good high-temperature resistance and long-term stability to withstand the operating environment of high-power lasers.

 

4. Connecting Pipelines

 

The design of the connecting pipelines is also crucial. High-quality, high-pressure, and high-temperature resistant tubing is typically selected to ensure system stability during long-term operation. Additionally, the layout of the pipelines should minimize fluid flow resistance to avoid reduced flow rates that could impact cooling efficiency.
