The Laboratorial Research of Two-Phase Free Convection Devices for Cooling of Materials and Industrial Machines
Refrigeration systems based on free convection (two-phase thermosyphons) are used for cooling equipment units in chemical, nuclear power, and steel-making industries, as well as for thermal stabilization of natural materials with temperature-dependent properties, such as permafrost. Results of labor...
