Qu Tubes for High Temperature Heat Rejection
ABSTRACT: In our proposed Phase II effort, we will be demonstrating long-lived aqueous aluminum heat pipes. The work will directly demonstrate the corrosion inhibition character of two different aqueous work fluids and the long-term heat flux performance of our heat pipe designs at an operating temperature of 200 Deg C. In addition, we will demonstrate the performance of an advanced, aluminum-based wick material that exhibits both high thermal conductivity and high strength. With its higher operating temperature, our heat pipe design will allow for substantial mass savings in future satellite heat rejection systems. BENEFIT: We anticipate that our successful work will, for the first time, enable the use of aluminum heat pipes with aqueous working fluids that are capable of operation at 200 Deg C or even higher. Additionally, our efforts to demonstrate a new wick material will offer substantial performance benefits to state-of-the-art ammonia heat pipes.
