A heat pipe with limited heat transfer capabilities in one direction. The heat pipe, which transfers heat in one direction in normal fashion, also transfers heat in the reverse direction, but only up to a prescribed point, beyond which the reverse heat flow cuts off. It operates because of the use of a limited liquid filling and at least one artery which is closed at the normal evaporator end and open ended at the normal condenser end.

A heat pipe with normal heat transfer in a forward direction and limited heat transfer in the reverse direction comprising: a sealed evacuated casing with a normal evaporator and a normal condenser used for heat transfer in the forward direction; at least one liquid pumping capillary artery structure with a sealed end located at the normal evaporator of the heat pipe casing and an open end located at the normal condenser of the heat pipe casing; a liquid retaining means located at the normal condenser of the heat pipe, the liquid retaining means oriented so that liquid retained within it closes off the open end of the artery structure; and heat transfer liquid located within the casing in at least sufficient quantity so that, during heat transfer in the forward direction, sufficient liquid accumulates in the liquid retaining means to close off the open end of the artery structure.
