Abstract
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.
