Also have many advantages, such as easy to process and less scaling.
Utility model content
The technical issues of the utility model devises a kind of underground heat heat exchanger tube and geothermal heat exchanger, solves is existingly
That there are heat exchange efficiencies is low for heat exchanger, and heat exchange pipeline is easy fouling, heat exchange pipeline is easy by the defect of drawing crack.
In order to solve above-mentioned technical problem, the utility model uses following scheme:
A kind of underground heat heat exchanger tube, it is characterised in that: its material is that stainless steel exchanges heat bellows (1), the stainless steel heat exchange
Heat exchanging fluid in bellows (1) exchanges heat with the hot water in underground heat pond (3).
Further, any one end of stainless steel heat exchange bellows (1) forms connection knot by a nut (11)
Structure is connect with other pipelines, and nut (11) inner wall is equipped with a gasket seal (13) and is used for the bellows that exchanges heat to the stainless steel
(1) inlet and outlet carry out waterproof sealing.
Further, it is additionally provided with a snap ring (12) on nut (11) inner wall, the snap ring (12) is stuck in the stainless steel
Exchange heat bellows (1) two adjacent corrugations (14) between ensure stainless steel heat exchange bellows (1) not with the nut
(11) it separates.
A kind of geothermal heat exchanger, including above-mentioned underground heat heat exchanger tube.
Further, a circulating water pipe is formed by earth source heat pump (2) in stainless steel heat exchange bellows (1) inlet and outlet.
Further, stainless steel heat exchange bellows (1) is the heat exchange pipe fitting of single or more assembling.
The underground heat heat exchanger tube and geothermal heat exchanger have following compared with existing underground heat heat exchanger tube and geothermal heat exchanger
The utility model has the advantages that
(1) since heat exchanger tube is using bellows, pipe inner runner section is continuously mutated the utility model, causes fluid
It is in high turbulence state always in the case where flow velocity is very low, it is difficult to form laminar flow, make the main heat of convective heat transfer
Resistance is effectively overcome, and is managed inside and outside heat transfer and is strengthened simultaneously, thus heat transfer coefficient is very high, generally traditional shell-and-tube heat exchanger tube
2 to 3 times, substantially increase heat transfer efficiency.
(2) the utility model makes the particle in fluid be difficult to deposit fouling because of the high turbulence of fluid in runner, even if having
A small amount of dirt generates, due to medium inside and outside pipe turbulent flow, tube wall is washed away strongly, good antiscale property ability is strong.In addition, on bellows
There is the strains generated by tube side and shell side thermal (temperature difference) stress, make the curvature of the bellows with elastic characteristic that microcosmic change occur
Change, so that the ability for making bellows heat exchanger pipe have antiscale and scale removal, it is strong to substantially increase good antiscale property ability.
(3) the utility model using bellows because of its planform and the relatively thin characteristic of tube wall, in tube side and the shell side temperature difference
When stress is larger, micro-variations occur for the curvature of the bellows with elastic characteristic, effectively anti-to compensate, eliminate thermal stress
Phenomena such as traditional pipe shell type heat exchange Guan Yi is by drawing crack is stopped, so that stress compensation ability is strong.
(4) the utility model stainless steel corrugated tube also has anti-strong corrosive ability.
