The first article in this series on spreadsheet based thermal resistance network analysis [1] described a procedure for using Microsoft Excel to solve a thermal resistance network by applying matrix analysis. That article assumed that the values of the thermal resistances between nodes were both known and fixed. This article presents methods for simplifying the process of … [Read more...]
calculation corner: a spreadsheet based matrix solution for a thermal resistance network: part 1
Ross Wilcoxon Rockwell Collins Cedar Rapids, Iowa A thermal resistance network analysis begins by defining discrete points within a system, known as nodes, and the thermal resistance between each set of nodes. Boundary conditions for external heat inputs and reference temperature(s) are applied to the appropriate nodes. Equations to relate nodal temperatures can be generated … [Read more...]
