The monogroove heat pipe developed by Grumman utilizes an extruded cross section which separates the vapor space from the liquid return path (Fig. 1) ^[1][2].

Heat input and output are through the flat face on top of the vapor space. Since heat is not conducted through the wall of the liquid return path, the chance of arterial blockage due to vapor bubbles is significantly reduced. Wick structures are placed along the interior walls to deliver condensate from the artery to the evaporator. Monogroove heat pipes are proposed to be used for multi-kilowatt space radiator heat rejections systems ^[3][4].
