Water Cooling Plates
CNC-machined cold plates with internal channels for liquid cooling of power electronics, lasers, and high-density boards
Overview
•
CNC-machined cold plates for liquid cooling loops
•
Gun-drilled, milled, or dual-plate bonded channels
•
Aluminum 6061 / 6063 or copper for higher conductivity
•
Mounting flatness suited to power modules and CPUs
•
Pressure and leak testing before ship
•
Fits mid and small production volumes without die tooling
