The use of two phase closed thermosyphons has been on the rise in recent years. This is due to the fact that thermosyphons offer very low thermal resistance, are highly efficient and very easy to manufacture. Thermosyphons are especially suitable for applications where there is considerable distance between heat source and heat sink. One such application is in cooling the moderator of cold neutron source (CNS) of research nuclear reactors. However, the operational limit of the closed two phase thermosyphons has been the focus of very few studies. Most of these studies considered only the thermosyphon, but have not included the vapor reservoir. In this book, the fundamental working principles of Two-Phase Closed Thermosyphon with Reservoir (TPCTR) is reviewed. The various operational limits and the effects of the size of the vapor reservoir on the heat transport capacity are analyzed. An analytical model is developed and CFD analysis is carried out to study the nucleate boiling inside the thermosyphon.
