A high capacity re-entrant groove heat pipe for cryogenic and room temperature space applications.

Type of article: Article

Summary

The configuration consists of 24 re-entrant axial grooves extruded in an aluminium pipe. Using methane, the pipe demonstrated transport capacities as high as 165 watts/m in a level orientation at 115 K. This is an order of magnitude higher than state-of-the-art cryogenic heat pipe technology. The re-entrant design offers the high reliability and ease of fabrication. The extrusion can also be used at other temperatures with appropriate working fluids. The design lends itself to optimization for specific loads and temperatures, within the constraints of the extrusion process.
