Abstract
The utility model discloses an I-shaped hot rod used for keeping frozen earth stable for a buried pipeline in permafrost regions, wherein the hot rod is provided with a middle connection pipe; two ends of the connection pipe are respectively communicated with two groups of short pipes with the other ends being closed; the included angle of two short pipes in each group is an obtuse angle; the profile of the hot rod is approximatively I-shaped; the middle part of the middle connection pipe of the hot rod is provided with a non-metal jacket; and the hot rod is vacuumized and filled with low boiling point working medium. The I-shaped hot rod has high transmission efficiency, can effectively prevent the soil and the pipe from generating uneven sedimentation and keep the pipe stability, does not consume the electric energy, needs no expense for operation, saves cost and energy, has convenient installation and no maintenance, and can run reliably for a long time; and the temperature change and working condition of the hot rod are easily observed and monitored.
Description
Technical field the utility model relates to a kind of heat pipe.
Background technology is to satisfy the needs of economic development and engineering construction, and pipe works such as increasing oil transportation, gas transmission, water delivery need be built in the ever-frozen ground district.Consider from security standpoint, these pipelines should adopt bury mode lay.And buried pipeline run duration can heat surrounding soil, and frozen soil is melted, and then causes soil and pipeline to produce differential settlement, destroys the stability of pipeline, influences the normal conveying of pipeline.Be thermogenetic effect, otherness frost heave that effectively prevents the Permafrost Area buried pipeline and the pipe deforming destruction that thaw collapse caused, usually adopt refrigeration unit to carrying out mechanical refrigeration around the pipeline, its weak point is: not only will consume a lot of electric energy, be unfavorable for environmental protection and energy saving, and operating cost is also quite high, unreasonable economically.
The summary of the invention the purpose of this utility model is to provide a kind of neither consumed power not need the ever-frozen ground district buried pipeline that is used for of operating cost to keep the stable worker's type hot pin of frozen soil again.The utility model mainly is to be provided with hot pin in buried pipeline both sides, ever-frozen ground district.This hot pin has connecting leg in the middle of, and its two ends are connected with the short tube of two groups of other ends sealings respectively, and the angle of every group of two short tubes is the obtuse angle, makes the profile of hot pin roughly be worker's type.One group of two short tube of connecting leg upper end are condensation segment in the middle of the above-mentioned hot pin, and one group of two short tube of lower end are evaporator section.The connecting leg middle part is provided with the nonmetal jacket that prevents to disturb Working fluid phase changing in the middle of being preferably in this hot pin.Vacuumize and fill low boiling working fluid in the above-mentioned hot pin.Be preferably in above-mentioned hot pin outside and be provided with corrosion-inhibiting coating; Hot pin top is provided with the lifting clamping device.During use, the evaporator section of above-mentioned hot pin is embedded in the soil of pipeline both sides, the condensation segment of hot pin then is embedded in away from pipeline and near in the soil on the face of land.
Because hot pin is a kind of Cryo Heat Tube that can conduct heat under the little temperature difference, and has the thermal diode characteristic of unidirectional heat transfer again, therefore in the permafrost region buried pipeline, warm (crude oil is arranged, when water etc.) flowing through, the soil moisture around the pipeline can be apparently higher than the soil moisture and the atmospheric temperature away from pipeline, utilize the inner low boiling working fluid vapour-liquid two phase transformation convection circulations of filling of hot pin that the heat in the soil around the pipeline is transferred in the soil away from pipeline, prevent that soil and pipeline from producing differential settlement, keep the stability of pipeline, guarantee the normal conveying of former wet goods medium.When the soil moisture away from pipeline is higher than the temperature of pipeline surrounding soil (daytime summer and autumn), because hot pin has the thermal diode characteristic of unidirectional heat transfer, hot pin can not be delivered to these heats in the pipeline soil and pipeline all around.
The utility model compared with prior art has following advantage: 1, efficiency of thermal transfer height can prevent effectively that soil and pipeline from producing differential settlement, keeps the stability of pipeline; 2, need not consumed power, operation does not cost usefulness yet, not only reduces expenses but also energy-conservation; 3, simple installation need not safeguarded, can move reliably and with long-term; 4, the variations in temperature of hot pin and duty are observed and monitoring easily.
