Thermosyphons are basically a heat pipe without a wicking structure. Instead of a wicking structure, it relies on gravity to pull the liquid droplets from the condenser to the evaporator. A big advantage of thermosyphons is that you can make them cheaply and make them very long. But how do you calculate the limits of a thermosyphon and how do you apply them? That is the subject of this entry into coolTV.
