A heat pipe assembly (100) has a combined reservoir (102) and evaporator
(104), the evaporator (104) having ducts of a vapor manifold (106)
that exhausts vapor toward the condenser (108) instead of opposing the flow
of liquid condensate to the reservoir (102), and the evaporator (104)
having a wick passage that impels the condensate toward the reservoir (102)
instead of opposing the flow of vapor.
