http://www.parkerprecisioncooling.com - Parker Hannifin Precision Cooling Systems - Calum McConnell, Business Development Manager - EMEA, Global Renewable Energy, Parker Hannifin. presented at Hannover Messe 2013 in Hannover Germany. Using 2-phase Evaporative Precision Cooling to Increase the Performance of Power Conversion Systems.
Our game changing two-phase evaporative liquid cooling system uses technology that efficiently address IGBT cooling and other high-powered electronics, while enabling higher density and throughput. In addition, the closed-loop system is safer, smaller and more reliable than traditional water-based options.

  6. 6. How is it Better than Water? Uses Heat of Vaporization (Flow boiling) 1. Isothermal – All cold plates are close to the same temperature 2. Evaporative heat transfer is 2x-4x better than single-phase (water) convective heat transfer coefficient: 3. Smaller pumps due to lower flow rates Typically 75% or less flow rate than that of water cooling “Waterless Cooling” R134a or low pressure refrigerants R134a is common - auto air conditioners Dielectric - will not harm the electronics No corrosion or scaling No freezing (gels at -100C) Use or disclosure of data contained on this page is subject to the restrictions on the first page of this presentation.

  15. 15. Fluid Characteristics @ 25ºC Water & R134a • 1kg of R134a absorbs 176kJ of energy in its “phase change” • 1kg of water absorbs 4.2kJ of energy of every 1°C temperature rise • For a 6° Temperature rise water absorbs 25.2kJ per kg – goal is to minimize water temperature rise through rack to minimize size of heat exchanger • Therefore 1kg of R134a absorbs approximately 7 times more energy than water • 176kJ/25.2 = 6.98Water requires 7x more mass flow rate to absorb the same amount ofheat as R134a  Pump power required to remove 1kW of heat:  Water = 60 to 100 watts  R-134a = 12 watts Use or disclosure of data contained on this page is subject to the restrictions on the first page of this presentation.
