FIELD: construction. ^ SUBSTANCE: heat pipe system for thermal control of aerodrome and road surfaces includes undersurface upper heat-exchange elements made of pipes connected to each other crosswise and along the perimetre, the inner surface of the bottom in which is covered by layers and strips of a filter, placed below the level of soil freezing, lower heat exchange elements, design of which mirrorlike reflects the design of the upper heat exchanger elements, besides, the bottom of the middle pipe in each heat exchange element is connected to the upper of the middle pipe in the according lower heat exchange element by a vertical heat pipe, at the same time pipes arranged along the perimetre of each upper heat exchange element are equipped with steam nozzles connected by pipelines located outside the surface, via a steam header and a check valve with an adjustment reservoir, a tray of which is filled with a low boiling liquid, which also fills filters of all heat exchange elements and heat pipes. ^ EFFECT: higher efficiency of a heat pipe system of thermal control of aerodrome and road surfaces with usage of low potential heat of non-freezing soil and solar energy. ^ 1 cl, 9 dwg |
