Can cooling channels be customized through Bergek CNC machining?

A variety of common channel path designs, including U-shaped, serpentine, micro-channel, and pocket milling layouts, can be produced using CNC machining for custom liquid cold plate manufacturing.

This customization capability stems from the inherent technical characteristics of CNC machining: it controls tool paths through digital programming, offering a high degree of design freedom in three-dimensional space. This enables the precise transformation of design blueprints into complex internal cavities and flow paths. Consequently, engineers can create targeted designs based on specific factors such as heat source distribution, system flow requirements, pressure drop limitations, and installation space contours. For example, optimizing cooling efficiency and flow characteristics can be achieved by adjusting channel width, depth, path, and cross-sectional shape.

Therefore, this technology provides an effective pathway for achieving cooling solutions tailored to your specific power density, target flow rate, and mechanical layout based strictly on customer-provided designs and confirmed manufacturing feasibility. For extremely high power density or ultra-fine micro-channel requirements, alternative processes such as bonded or etched cold plates may sometimes be more suitable, while CNC-machined cooling plates remain a highly flexible and cost-effective solution for prototypes and low-to-medium volume production. In practical design, finalizing the channel geometry typically requires a comprehensive trade-off and optimization process that considers multiple factors, including thermal simulation analysis, structural strength, and manufacturing cost.
