Abstract:
Capillary Pumped Loops (CPL) are projected to be the primary heat transport device for the next generation spacecrafts and satellites. The major shortcoming of a traditional CPL system has been its inability to tolerate vapor and/or non-condensible gas (NCG) bubbles when they are present in the liquid side of the loop. The vapor/NCG bubbles ultimately caused the capillary pumps to fail. A novel CPL design concept, called Advanced CPL or A-CPL, was introduced to create deprime resistant capillary pumps. The main idea of the A-CPL was to generate a liquid flow through the capillary pump core to flush out vapor/NCG bubbles.
