Evolution™ Cold Plates

Niagara Thermal Products’ global leadership in the development of custom heat exchangers has inspired a new product line of cold plates for the direct contact cooling of electronics in a multitude of applications. Utilizing our wide array of heat transfer fin and existing manufacturing technologies, Niagara Thermal is able to meet or exceed the heat transfer performance of any aluminum brazed cold plate being produced today.

Custom engineered Evolution™ cold plates offer the performance required in all of the vacuum brazed folded fin cold plate applications of today. Working with Niagara Thermal Products offers significant benefits:
  • An engineering team with expertise in the design and manufacture of folded fin
  • Heat exchanger and cold plate modeling capability
  • Vertically integrated manufacturing operation
  • Aluminum, stainless steel, copper, cupro nickel and inconel brazing capability
  • Liquid loop system expertise
  • Two phase cooling system expertise
  • The ability to provide other heat exchangers in the system.
  • A track record of quality in the Aerospace and Defense markets (AS 9100, ISO 9001)
A systems level understanding of the entire liquid or two phase loop gives us the advantage over other cold plate manufacturers. We can support the development of thermal resistance targets, thermal interface material, fluid pumping and airflow systems as well as other key technical aspects of liquid cooling loops.

The broad range of manufacturing methods provides an unusually large spectrum of possible strategies for enhancing heat transfer and optimizing fluid flow through the cold plate.
