Water Cooling Plates

CNC-machined cold plates with internal channels for liquid cooling of power electronics, lasers, and high-density boards

Water Cooling Plates

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

Technical Specifications
