FIELD: heating system.
SUBSTANCE: thermosyphon contains a body whose working volume of the lower chamber is filled with liquid, a funnel that fences with a gap the lower chamber with a vapor pipeline for steam transportation, an upper chamber, a valve for dropping air outwards. In the upper chamber, a capacitor body is input, filled to a predetermined level with a liquid and connected to a vapour pipeline connected to a syphon whose end is located in the capacitor liquid. In the casing of capacitor holes are made and additional funnel is introduced with gap with respect to the casing, located at the level of its liquid, and the upper part of the body is equipped with a valve. The syphon can be made in the form of an inverted glass above the vapor pipeline, and an annular fine-celled filler made of metal can be placed in the evaporating zone.
EFFECT: increase the efficiency of evaporation of the liquid.
