Thermal Energy Storage and Heat Transfer Support Program. Task-1. Heat Transport System Study Copper-Water and Steel-Sodium DWAHP. Volume 1.
Abstract
This report covers the test results of some extended research conducted on both 2m copper-water double wall artery heat pipe and 2m stainless steel-sodium heat pipe. The experimental results of the effective thermal conductivity of the wick agree with the predicted results. It is shown that the double wall wick is a 'boiling-tolerant' wick and it can support high radial heat flux. The 2m sodium-SS 304 heat pipe was successfully tested using a pyrolytic graphite heater after facing several failures with nichrome and cartridge type heaters. Inert gas-filled mode and conventional mode startup tests were conducted. The startup from frozen state was smooth in gas-filled mode whereas similar startup attempt was rough in the conventional mode. Calorimetric measurement of heat losses and tilt test results are also presented.
