Auxiliary evaporator for dual mode heat pipes
A dual model heat pipe for use in roadways, bridges, etc., includes an auxiliary evaporator formed concentrically with the upper end of a vertically disposed primary evaporator portion. The auxiliary evaporator portion comprises an annular sleeve disposed about the upper end of the primary evaporator portion and arranged between the primary evaporator portion and the condenser portion of the heat pipe such that all of the condensed working fluid returning to the primary evaporator portion must enter and overflow the auxiliary evaporator portion prior to return to the primary evaporator portion. The auxiliary evaporator portion is provided with heat input means whereby the auxiliary evaporator may function even in the absence of heat pipe function by the primary evaporator.
