Abstract
The utility model relates to an underground flexible thermal probe, which is easy for heat dissipation, is used for keeping the stability of frozen soils, and mainly has the structure that a ventiduct which traverses two sides of a foundational engineering is arranged outside a condensation segment of the underground flexible thermal probe, and a strut member is preferably arranged on the ventiduct or the condensation segment of the thermal probe; mesh enclosures are arranged on openings at two ends of the ventiduct; and anticorrosive coatings are arranged on the inner surface and the outer surface of a metal ventiduct. The underground flexible thermal probe has simple structure and convenient installation, and can operate effectively for a long time; and in addition, the radiating effect of the condensation segment of the underground flexible thermal probe is improved effectively, and the heat transfer efficiency of the underground flexible thermal probe is further enhanced.
Description
Technical field the utility model relates to a kind of hot pin.
Background technology is in order to keep ever-frozen ground stable, make the Foundation Design of establishing thereon breakoff phenomenons such as depression, distortion, cracking can not occur, someone has designed buried flexible hot rod, its application number is that 2007200157215. its primary structures are: this hot pin can place the condensation segment and the evaporator section that can place frozen soil layer in the Foundation Design of ground, both are linked to be the integral body that can be any angle of inclination by flexible steel in flat section tubing, and are provided with heat-transfer working medium in the vacuum chamber of sealing.Its weak point is: because the flexible hot rod condensation segment is embedded in the Foundation Design, therefore have bigger thermal contact resistance, limited the heat radiation of flexible hot rod condensation segment, thereby caused the heat pipe operating efficiency low.
The summary of the invention the purpose of this utility model is to provide a kind of a kind of stable buried flexible hot rod of easy heat radiation of frozen soil that keeps that improves buried flexible hot rod condensation segment radiating effect.
The utility model mainly is based on existing buried flexible hot rod (it can be monolithic construction, also can be split-type structural), establishing a sleeve pipe in this flexible hot rod condensation segment outside is air chimney, this air chimney both ends open reaches respectively outside the Foundation Design of ground, the air chimney that promptly traverses (parallel to the ground or not parallel to the ground) Foundation Design and be connected with ambient atmosphere, its both ends open can be that uncovered also can setting up defences as required ended the guard that foreign matter enters.Above-mentioned air chimney can be various materials such as metal, engineering plastics or steel concrete, preferably establishes anticorrosive coat as adopting its surfaces externally and internally of metal tube.The quantity that above-mentioned air chimney is installed can determine as required that as establish the flexible hot rod of air chimney along one of subgrade cross section direction installation, two or more outside, it can adopt the in-line arrangement mode, also can adopt wrong emission type.Be preferably on air chimney or the hot pin condensation segment and establish support member, its form of structure can have multiple, as Y shape, T shape or semicircular arc, the effect of this support member is to be used for the location of hot pin and support, prevent distortion and the displacement of hot pin condensation segment in the subgrade construction process, guarantee that the vapour-liquid two-phase circulation of hot pin is unaffected.
This air chimney is under the effect of wind tunnel effect, and the air in the air chimney is in flow regime, and the heat in the frozen soil is transferred in the air, has strengthened the heat transfer of hot pin condensation segment, has improved the heat-transfer effect of hot pin.In addition, because the density of cold air is greater than hot air, cold air can accumulate in the air chimney, also helps the work of hot pin.
The utility model compared with prior art has following advantage:
1, improves the radiating effect of buried flexible hot rod condensation segment effectively, and then improved the heat transfer efficiency of buried flexible hot rod.
2, simple in structure, easy for installation, can permanently effectively move.
Description of drawings
Fig. 1 is the utility model user mode section simplified schematic diagram.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment is in a kind of the maintenance in the buried flexible hot rod simplified schematic diagram of the stable easy heat radiation of frozen soil illustrated in figures 1 and 2, in linking to each other by flexible steel in flat section tubing heat-transfer working medium, peripheral hardware anticorrosive coat flexible hot rod 1 are arranged, its evaporator section 2 is located in the ever-frozen ground layer 4 under the roadbed 3, there is the condensation segment 5 of radiating fin to be located in the roadbed outside it, the metal vents 6 of traversing the roadbed both sides is established in this condensation segment outside that is located in the roadbed, and its surfaces externally and internally is established anticorrosive coat.In air chimney, establish Y shape support member 7.
