Distance, enhancing outer tube and surrounding soil heat transfer effect, are the important components of the technology, have to energy storage effect decisive
Meaning.During the popularization and application of the technology, since helical-blade connects within needing between inside and outside casing, processing
Complexity, assembly difficulty cause cost excessively high, are unfavorable for promoting and applying as early as possible.
Summary of the invention
Based on problem above, the present invention provides a kind of whirlwind casing type heat exchanging soil energy storage spiral ground pile, in the company of eliminating
Under the premise of the inside spin leaf for connecing inside and outside casing, another formation spiral air flow mode in annular channel is given, product is made
Process and assemble is more convenient, and manufacturing cost reduces, and is conducive to large-scale promotion application.
In order to realize goal of the invention, the present invention adopts the following technical scheme: a kind of whirlwind casing type heat exchanging soil energy storage spiral shell
Ground pile, the outer tube being longitudinally embedded in soil including big portion are revolved, outer tube internal clearance is socketed with inner sleeve, inner sleeve and housing
Interlayer is formed between pipe, using interlayer as updrift side, air flow channel is constituted by downstream direction of inner sleeve, air flow channel is equipped with
Blower, the upper end of interlayer are connected with air inlet spiral case；The air inlet direction of air inlet spiral case be it is tangential enter, along interlayer rotate to
Under.
The whirlwind casing type heat exchanging soil energy storage spiral ground pile of this programme design, main structure are continued to use in CN108458508A
Technical solution, be a bilayer sleeve, outside, in inner sleeve gap is socketed in, inner sleeve usually selects outer tube with outer tube
Select round tube.In order to thermally conductive, outer tube suggestion selects metal tube；In order to heat-insulated, inner sleeve suggestion selects plastic tube.Inner sleeve and outer
Interlayer is formed between casing, air-flow comes downwards to always inner sleeve from interlayer is entered between internal and external casing above the ground along longitudinal direction
Lower ending opening go out, enter back into inner sleeve uplink, from inner sleeve upper end opening be discharged, an air flow channel is formed, in air stream
Road is equipped with blower, carries out external force promotion to air-flow.Outer tube upper and lower side is all closed, and is not designed between inner sleeve and outer tube
Inside spin leaf, only in interlayer upper end, design has air inlet spiral case, and tangent line of the air inlet direction of air inlet spiral case along junction enters,
Downwards along interlayer rotation, air swirl is formed.The air swirl formed in this way, it is sufficient in the traditional structure that matches in excellence or beauty
The air swirl that helical-blade forces limit to be formed, but due to not used inside spin leaf, the production dress of inside and outside casing
With with regard to very simple, manufacturing cost can be remarkably decreased, and be conducive to product promotion use.It is specifically upper in application, outside outer tube
