Loop heat pipe - Wikipedia
A loop heat pipe (LHP) is a two-phase heat transfer device that uses capillary action to remove heat from a source and passively move it to a condenser or radiator.

This is the presentation file for the short course Introduction to Loop Heat Pipes, to be conducted at the 2015 Thermal Fluids and Analysis Workshop, August 3-7, 2015, Silver Spring, Maryland. This course will discuss operating principles and performance characteristics of a loop heat pipe.
Loop Heat Pipes. A loop heat pipe is capable of transporting heat over long distances relative to a conventional heat pipe. The evaporator and condenser sections are not integrated within a single tube, but are physically separated and connected by vapor and liquid transport lines.
Capillary pumped loops (CPLs) and loop heat pipes (LHPs) are versatile two-phase heat transfer devices which have recently gained increasing acceptance in space applications. Both systems work based on the same principles and have very similar designs.
