节能电子制冷项目最终技术报告
Parker Precision Cooling Business Unit was awarded a Department of Energy grant (DE-EE0000412) to support the DOE - ITP goal of reducing industrial energy intensity and GHG emissions. The project proposed by Precision Cooling was to accelerate the development of a cooling technology for high heat generating electronics components. These components are specifically related to power electronics found in power drives focused on the inverter, converter and transformer modules. The proposed cooling system was expected to simultaneously remove heat from all three of the major modules listed above, while remaining dielectric under all operating conditions. Development of the cooling system to meet specific customers requirements and constraints not only required a robust system design, but also new components to support long system functionality. Components requiring further development and testing during this project included pumps, fluid couplings, cold plates and condensers. All four of these major categories of components are required in every Precision Cooling system. Not only was design a key area of focus, but the process for manufacturing these components had to be determined and proven through the system development. The Precision Cooling Business Unit identified a few key projects to be the focus of the DOE grant. The first key project was to develop a cooling system for low voltage industrial drives used for power conversion and inversion. These systems utilize insulated-gate bipolar transistors (IGBTs) to complete switching at very high frequencies in a small amount of space. The use of IGBTs results in relatively high amounts of heat needing to be dissipated, or removed, from the electrical device efficiently. Water and air have been used for cooling these devices, but require the device to be de-rated at elevated ambient temperatures, because they do not have the thermal capacity of Parkers Vaporizable Dielectric Fluid (VDF) cooling system.
