Loops Heat Pipes (LHP) technology was created as a solution to existing issues of the regular heat pipes. The heat pipes efficiency depends on direction significantly; having a limited capability to transfer a significant amount of heat, especially for long distances. Unlike traditional heat pipes LHP does not depend on the gravity field direction and they are able to move a massive amount of heat to a very long distance.
Conventional Heat Pipes and their Disadvantages

Two-phase heat transfer device operating on a closed evaporation - condensation cycle and using capillary forces as a “driving” mechanism.
Maximum capacity decreases abruptly for long distance and under the field of gravity
