ABSTRACT:
A heat pipe (90) of increased heat transport capacity, capable of being primed under gravity conditions, comprises a sealed envelope (95) defining an evaporator (110) and a condenser (115). An arterial tube (125) of large liquid carrying capability is provided with an axial slot (130) formed on the upper surface of a segment of the tube (125). The slot (130) has beveled surfaces (135), (140) which increase the capillary pumping action to transverse wicking bodies (150, 155). The bodies (150, 155) transport working fluid to or from circumferential grooves (120) formed in the evaporator (110) and condenser (115).
