Description
Technical field: the utility model relates to hot pin, is specially a kind of basic soil layer that is used for ever-frozen ground ground district railway, highway, bridge, culvert, oil transportation and gas transmission line, building construction and subterranean railway and stablizes the employed environment-friendly high-speed low temperature hot-bar apparatus of Thermal Power Engineering such as reaching the landslide control.
Background technology: frozen soil is a kind of special, natural body that low temperature has become, its frost heave, thaw collapse phenomenon will cause sink deformation, the hillside heat of roadbed to melt breakoff phenomenons such as slump, culvert cracking, are the main key technologies that cold district railway, highway engineering construction need solve.Existing Cryo Heat Tube technology mostly is low temperature ammonia gravity assisted heat pipe, and fin is equipped with on the top of pipe, is radiating segment.The bottom of pipe is imbedded in the ever-frozen ground, is evaporator section.In cold season, because air themperature is lower than the ever-frozen ground temperature, the liquid working substance in the heat pipe absorbs the heat in the ever-frozen ground, flashes to gas.Steam is under the driving of pressure reduction, travel up to heat pipe top along the heat pipe central passage, run into colder tube wall and emit the latent heat of vaporization, be condensed into liquid, the liquid working substance film is under the gravity effect, flow back to evaporator section along tube wall and evaporate, so circulation is transferred to the heat in the ground ever-frozen ground in the atmosphere continuously.Because the distinctive heat-transfer mechanism of gravity assisted heat pipe, heat can only conduct heat from bottom to top, and can not transmit from top to bottom, in warm season, air themperature is higher than the ever-frozen ground temperature, the steam of liquid working substance evaporation is to heat pipe top after, and owing to tube wall temperature is higher, steam can not condensation, after reaching stream-liquid phase balance, liquid stops evaporation, and heat pipe quits work, and the heat in the atmosphere just can not pass in the ever-frozen ground by heat pipe like this.Because of the Cryo Heat Tube that solves frozen soil needs long size, therefore the caliber that cooperates is also corresponding wants thick, in theory, extra heavy pipe directly contacts more land area, good working effect, but, the working medium amount that needs owing to thick excessively caliber is bigger, and big working medium amount influences evaporation efficiency in caliber, therefore the working medium groundwater increment of hot pin is the principal element that influences diameter, use more than the working medium of domestic Cryo Heat Tube is present to be ammonia or fluorine, this does not allow to use aspect environmental protection, and products export is produced obstacle.
Summary of the invention: the purpose of this utility model is exactly in order to solve above-mentioned frozen soil layer stability problem, provide a kind of simple in structure, with low cost, it is big to have heat-transfer capability, toggle speed is fast, average temperature performance is good, and heat transfer temperature difference is little, unidirectional heat transfer, through-put power is big, the environment-friendly high-speed low temperature hot-bar apparatus of the band internal structure of long service life.The purpose of this utility model is achieved in that it comprises lifting bayonet socket (1), medium fill orifice (2), heat radiation condensation end fin (3), vacuum envelope (4), vacuum work cavity (5), secondary vacuum phase transformation cavity shell (6), secondary vacuum phase transformation cavity (7), the secondary vacuum medium fill orifice (8) of bleeding.The secondary vacuum that a end at vacuum envelope (4) has lifting bayonet socket (1), the other end has communicates with secondary vacuum phase transformation cavity (7) the medium fill orifice (8) of bleeding, end at vacuum work cavity (5) has secondary vacuum phase transformation cavity shell (6), the other end to be connected with medium fill orifice (2), and heat radiation condensation end fin (3) is arranged on the external side of vacuum envelope (4).The thickness of condensation end fin (3) is 0.1-3mm, highly is 0.2-100mm.The diameter of vacuum envelope (4) is 2-400mm, and long is 1-50m.The utility model has the advantages that: it is big to have heat-transfer capability, toggle speed is fast, average temperature performance is good, heat transfer temperature difference is little, unidirectional heat transfer, and through-put power is big, characteristics such as long service life, so it is stable that the utility model can be widely used in plateau permafrost ground road and rail, bridge culvert roadbed and power transmission and transformation iron tower foundation, airfield runway and road snow melt are in the engineerings such as utilization of low temperature underground heat.Serviceability is stable, and can reach more than 30 years service life.
