Abstract
An improved heat pipe (115) of increased heat transport capacity comprising a vapor tube (120) and a liquid-condensate return tube (130). An outwardly extending conduit (125), disposed in both the evaporator section (135) and evaporator section (140) of the heat pipe (115), provides fluid communication between the vapor tube (120) and the return tube (130). Circumferential v-shaped grooves (145) terminate at a slot-like opening (165) formed in each of the conduits (125). A cap member (170) traverses each opening (165) and coacts with the grooves (145) to form a plurality of fluid passageways (175).
