Heat pipe thermal control of slender optics probes
Abstract
The thermal design for a stereographic viewing system is presented. The design incorporates an annular heat pipe and thermal isolation techniques. Test results are compared with design predictions for a prototype configuration. Test data obtained during heat pipe startup showing temperature gradients along the evaporator wall are presented. Correlations relating maximum well temperature differences to a liquid Reynolds number were obtained at low power levels. These results are compared with Nusselt's falling film theory.
