%X To validate proposed axially grooved heat pipe, designed to work with acetone, comparative characterization tests have been conducted for two heat pipes, having the same profile height of 19.1 mm, and length of 730 mm. First heat pipe is charged with acetone and has unique core however the second heat pipe, charged with ammonia, has two cores. Both heat pipes are directed to Space application and have profiles with similar flat interfaces to fit inserting in honeycomb satellite panels. Two different characterization tests were performed. First, an inclination test conducted by means of a motorized table; second, a dry-out test in horizontal position at different temperatures. The characteristic curves were obtained for both HP profiles under symmetrical heating/cooling.
