Abstract
A heat pipe wick which can survive freezing of the heat transfer fluid within the heat pipe and return to full operation automatically. A flexible high lift wick is used with a limited liquid inventory to prevent damage from freezing. The limited amount of liquid is completely retained in the wick at all times by capillary forces preventing puddling at the lowest point in the heat pipe, thus avoiding damage to the casing by expansion.
