Analysis and evaluation of extended surface thermal systems

OSTI ID:6346148
The book presents simplified algorithms and methods for the assembly of heat-dispersing fins into complicated arrays. Every common fin or spine is shown to be describable by a 2 x 2 thermal transmission or transmission parameter matrix for relating situations of temperature excess and heat transfer at the fin tip to conditions at the base. Fins and spines with no tip, e.g., longitudinal fins with a triangular profile, or a conical spine, are demonstrated to have a heat transfer profile or input admittance which relates the base heat flow to the base temperature excess. Once the 2 x 2 matrices or input admittances are calculated for each fin in an array, overall array performance can be determined through the algorithms presented. The matrix-oriented algorithms are designed to manipulate the individual 2 x 2 matrices into an expression for behavior of a single large fin.
