MacroFlowTM Significantly Improves the Productivity of the Thermal Design Process
牋?MacroFlow is a unique software tool for simple, fast, and accurate analysis of the thermal performance of electronics cooling systems based on the technique of Flow Network Modeling (FNM). The conventional approaches of hand calculations/spreadsheets or CFD have significant drawbacks when used for system-level thermal design. Hand calculations are prone to error while spreadsheets are system-specific and inflexible. CFD, on the other hand, is time consuming in terms of model setup, calculations, and examination of results. The FNM technique provides flexibility, accuracy, and speed. In this technique, the cooling system is represented as a network of flow paths and components possessing overall characteristics for quick prediction of the systemwide flow and temperature distributions.
牋?MacroFlow enables thermal engineers to realize the promise of the FNM technique for obtaining significant productivity improvements in the design process. It has the following capabilities:
Intuitive Graphical User Interface (GUI) ?An easy-to-use point-and-click interface and a comprehensive component library allows easy construction of the network models for all practical electronics systems.
Component Library ?The library of components contains standard flow components such as bends, area changes, orifices, and tee-junctions as well as electronics cooling components such as heat sinks, filters, fans, and power supplies. Empirical correlations based on the geometry and flow conditions are already incorporated to determine the flow and heat transfer characteristics of the components. Further, the library can be customized by the user by specifying flow and thermal resistances in various mathematical forms.
Powerful Solution Method ?MacroFlow a direct solution technique for robust and rapid calculation. Results for a typical system are obtained in less than a minute on a PC.
Comprehensive Postprocessing - Systemwide flow and temperature distributions can be examined in the form of bar charts, tables, on-screen display, and animation.
牋牋 MacroFlow is useful for addressing the following system-level thermal design issues:
Examination of different physical layouts
揥hat If?studies such as fan failure, rise in ambient temperature, and filter degradation
Sizing of fans, heat sinks, screens, and filters
Identification of performance-limiting components
Effect of heat sink bypass
Systemwide effects of a design change
牋?Use of MacroFlow enables the thermal engineer to address 80% of the design problems is less than 10% of the time relative to the conventional methods such as spreadsheets or detailed CFD analysis. Its use early in the design cycle allows hundreds of design options to be examined within a day to quickly arrive at a few good designs for detailed analysis and laboratory testing. MacroFlow dramatically improves the productivity of the thermal design process and significantly shortens the design cycle.
牋?MacroFlow is being widely used for the thermal design of air and liquid-cooled systems in computer, telecommunication, peripheral, defense, aerospace, semiconductor, and power electronics industries. Examples of the systems designed using MacroFlow include air-cooled servers, telecom cabinets, projectors, and liquid-cooled test equipment and cold plates. A number of case studies describing such applications are available on our website
