Abstract
A fuel conveying member in a fuel system of a gas turbine engine includes a heat pipe disposed in heat transfer communication with a fuel flow passage of the fuel conveying member, such that heat is transferred by the heat pipe from a high temperature region to a lower temperature region of the fuel flow passage. The heat pipe has a constant mass or working fluid enclosed within a sealed chamber in heat transfer communication with fuel in said fuel flow passage, said working fluid being self-circulating in a fluid flow having a liquid portion and a vapor portion, said working fluid passively boiling, flowing and condensing to transfer heat from said high temperature region to said lower temperature region.
