Aqueous Solution Heat Pipe Transport: Qu-Tube vs. Capillary-Pumped Heat Pipe

Abstract

This report provides details on an in-house test effort that was conducted to evaluate the performance of a novel heat transfer device. The subject heat transfer device is one for which some intriguing performance claims have been made. Qu-tubes, or Advanced Thermal Transport Devices (ATTDs), are said to be entirely dry on the inside, act independently of gravity, exhibit very high conductivity, work over large distances and temperature ranges, and operate at a lower pressure than traditional heat pipes. The Aerospace Systems Directorate of the Air Force Research Laboratory purchased Qu-tubes and equipment to thoroughly examine the operation limits of such a device.
