Popis: Flexible heat pipes utilizing ultra-high-molecular-weight (UHMW) Ž lm wicks and formed UHMW wicks with Kapton® and aluminized Mylar® containers were designed, fabricated, and tested. Wick characterization was performed on both wicks with acetone, methanol, freon, and ethanol. The thin-Ž lm UHMW wick had a larger permeability and capillary radius. Burst tests were performed on the Mylar and Kapton heat-pipe containers indicating sufŽ cient strength for the heat-pipe application. The heat pipes were charged with methanol as the working  uid and successfully tested at steady-state conditions. Relatively uniform temperatures were obtained during several days of testing.
