Compared with prior art, ground burying heat exchange tube provided by the invention is set to spring shape by the heat exchange portion of ground burying heat exchange tube, in the drilling well of same depth, can extend longer duct length, obtain and the more heat exchange area of soil, improve heat exchanger effectiveness, reduced difficulty of construction.
Brief description of the drawings
Fig. 1 is that the buried pipe heat exchanger of an embodiment of the present invention is arranged on the schematic diagram in soil.
Detailed description of the invention
Describe the present invention below with reference to detailed description of the invention shown in the drawings.But these embodiments do not limit the present invention, the conversion in structure, method or function that those of ordinary skill in the art makes according to these embodiments is all included in protection scope of the present invention.
Join Fig. 1, introduce a detailed description of the invention of ground burying heat exchange tube of the present invention.In the present embodiment, this ground burying heat exchange tube 20 comprises heat exchange portion 21 and gravity portion 22.
Heat exchange portion 21 is spring shape, by the spring shape that heat exchange portion 21 is arranged to spiral, after installing, in the drilling well of same depth, longer duct length can extend in heat exchange portion 21, to obtain the heat exchange area larger with surrounding soil, improve heat exchange efficiency, correspondingly, under default hot exchange power, need less drilling depth, and then reduced difficulty of construction.In actual application, ground burying heat exchange tube 20 of the present invention is because unit linear meter(lin.m.) interior conduit length increases, thus the heat exchange amount that increases unit linear meter(lin.m.) more than 4 times, and the corresponding minimizing of drilling depth is more than 3 ~ 4 times simultaneously.
As preferred embodiment, this ground burying heat exchange tube 20 also comprises the gravity portion 22 being connected with heat exchange portion 21.When installation, ground burying heat exchange tube 20 entirety can be under the effect of gravity portion 22, in the smooth drilling well that enters to accomplish fluently, and need to down give by aid unlike traditional ground burying heat exchange tube, more convenient, and can avoid friction between pipeline and the coarse borehole wall that External Force Acting causes and aid misoperation time, produce the damage to pipeline, affect the operational effect of ground burying heat exchange tube.
Further preferred, the center of gravity of ground burying heat exchange tube 20 is positioned at described gravity portion 22, so can ensure 22 heat exchanging portions 21 of gravity portion better traction effects are installed.
Because the heat exchange portion 21 of ground burying heat exchange tube 20 of the present invention is spring shape, so there is certain scalable deformation behavior, so, can be in different condition of construction, outfit has the gravity portion 22 of different quality, ground burying heat exchange tube 20 is declined and extend in the default degree of depth.
It is worth mentioning that, the heat exchange portion 21 of ground burying heat exchange tube 20 of the present invention is PAP, and its basic comprising is five layers, is followed successively by from inside to outside plastics, PUR, aluminium alloy, PUR, plastics.PAP has good heat-insulating property, and inside and outside wall is not perishable, and because of inner wall smooth, convection cell resistance is very little; Again because can be arbitrarily bending, thus installation facilitate, the heat exchange portion 21 that is suitable for making ground burying heat exchange tube 20 of the present invention.
Continue ginseng Fig. 1, introduce a detailed description of the invention of buried pipe heat exchanger 100 of the present invention.In the present embodiment, this buried pipe heat exchanger 100 comprises heat exchanger tube main body 10 and ground burying heat exchange tube 20.
Ground burying heat exchange tube 20 comprises heat exchange portion 21, and this heat exchange portion 21 comprises the first end 211 connected with heat exchanger tube main body 10 and the second relative end 212, one gravity portions 22 are connected on this second end 212 with first end 211.The concrete structure of ground burying heat exchange tube 20 has done detailed narration in the above-described embodiment, therefore do not repeat them here.
Heat exchanger tube main body 10 and ground burying heat exchange tube 20 fluid connections, usually, can for example adopt water as heat transferring medium, to realize the transmission of heat from ground burying heat exchange tube 20 to heat exchanger tube main body 10.
The present invention is by above-mentioned embodiment, there is following beneficial effect: the buried pipe heat exchanger 100 that adopts ground burying heat exchange tube 20 of the present invention, by the heat exchange portion 21 of ground burying heat exchange tube 20 is set to spring shape, in the drilling well of same depth, can extend longer duct length, obtain and the more heat exchange area of soil, improve heat exchanger effectiveness, reduced difficulty of construction.
