Mapping Temperatures On Heat Pipes
Author and Affiliation:
Gunnerson, Fred S.(University of Central Florida)
Thorncroft, Glen E.(University of Central Florida)
Abstract: Paints containing thermochromic liquid crystals (TLC's) used to map temperatures on heat pipes and thermosyphons. Color of thermally sensitive TLC coat changes reversibly upon heating or cooling. Each distinct color indicates particular temperature. Transient and steady-state isotherms become visible as colored bands. Positions and movements of bands yield information about startup transients, steady-state operation, cooler regions containing noncondensible gas, and other phenomena relevant to performance of heat pipe.
