  This paper focuses on the performance analysis of the startup and transient characteristics of heat pipe radiator unit and its possible heat transport limits under space radiation environment. Finite difference method is adopted to solve the heat conduction equations for the fin attached on the heat pipe condenser.   Although high temperature, liquid metal heat pipe radiators have become a standard component on most space nuclear power systems, there is no experimental data on the operation of these heat pipes in a zero gravity or micro gravity environment. Experiments to benchmark the transient and steady state performance of prototypical heat pipe space radiator elements are in preparation. 28 years of space power-related liquid-metal heat pipe research that has been conducted at Los Alamos since the invention of the heat pipe. Description and Technology of Heat Pipes. the sintered powder metal heat pipe compared to the groove and mesh heat pipes. For 6mm OD, the groove heat pipe has the best performance from +90° to 0° (horizontal position) followed by sintered metal powder and mesh.. However, for 5mm heat pipe, the groove wick and sintered metal powder wick thermal performance were similar from +90° to 0°.

Metal Heat Pipe Space Shuttle Experiment”, This book on liquid-metal coolants fills the void of knowledge concerning heat pipe properties and other applications. Performance Analysis of. Although NaK is a liquid phase at room temperature, the startup time of heat pipe C (about 7 to 8 minutes) was not shorter than the heat pipe B. The effect of a gravitational force on heat pipe performance was also estimated by inclining the heat pipe at an angle of 90 deg. prototype heat pipes, the first of which used water as a working fluid, and was soon followed by a sodium heat pipe which operated at K. Grover and his co-workers also demonstrated the effectiveness of heat pipes as a high performance heat transmission device and proposed several applications for . A new oscillating heat pipe (OHP) charged with hybrid fluids can improve thermal performance. The key difference in this OHP is that it uses room temperature liquid metal (Galinstan consisting of gallium, indium, and tin) and water as the working fluid. The OHP was fabricated on a copper plate with six turns and a 3 × 3 mm 2 cross section. The.
