Description
Technical field
This utility model belongs to energy stake technical field, is specifically related to a kind of energy stake heat exchanging pipe structure.
Background technology
Energy stake is pile foundation to be combined with earth source heat pump, both can carry fabric structure, utilizes shallow-layer ground simultaneously
In lower soil, rock, subsoil water or other media, a large amount of low-temperature heat sources of storage provide heating installation, air-conditioning and heat for space
Water, which overcomes the defect of the earth-source hot-pump system of vertical drilling hole pipe laying, can reduce the occupation of land face of earth-source hot-pump system simultaneously
Amass and investment, be the green building technique of a kind of low cost highly widelyd popularize.
At present, the building basis of China is with cast-in-situ bored pile as principal mode, and energy stake refers generally at cast-in-situ bored pile
In pre-buried plastic tube heat exchanger tube (usually PE pipe), then remove in stake well with steel reinforcement cage one, then casting concrete form.Its
In, plastic tube heat exchanger tube mainly has five types, be respectively single the most U-shaped, connect double-U-shaped (W type), parallel connection is double-U-shaped and ter is U-shaped
With single-screw type.
In the research application of existing energy stake heat exchanger tube the most few in number, mainly continue to use plastic tube heat exchange
U-shaped, the W type of pipe or the cloth Manifold technology of screw type, U-shaped piping mode is simple, and the heat interference between pipeline is less, easy construction,
In order to increase heat transfer area, improve the service efficiency of energy stake, often use W type or U-shaped piping mode in parallel, energy on the whole
The heat exchange efficiency of stake improves along with the increase of pipe laying quantity.Current research relate generally to the heat interference between different pipeline,
The aspect such as different piping mode and increase heat transfer area in steel reinforcement cage, and the investigation of materials using pipeline itself is less, one
As use PE pipe, the utility model proposes the descending branch at heat exchange pipeline and use the metal that other heat transfer coefficients such as steel pipe are bigger
Pipe, increases its heat transfer efficiency, and in certain position of ascent stage, in pipe, the temperature of circulating liquid is close to the temperature at the bottom of stake, rises
Time will carry out contrary heat exchange with the soil body, the insulation material pipe that heat transfer coefficient is less should be changed into, this optimal heat exchange position and
The flow velocity of circulating liquid, the distribution situation of soil body temperature and pipeline are relevant with the heat transfer efficiency of the soil body, below this position,
Circulating liquid absorbs thermal source or low-temperature receiver from the soil body, then releases energy time up.And, at home owing to starting late,
For its pipeline structure structure, heat transfer mechanism, the aspects such as the impact of stake self load-carrying properties and engineering design method are all lacked
Relevant research.
Utility model content
This utility model is for the shortest problem of energy stake fluid one way in prior art, it is provided that a kind of new heat exchanging pipe
Structure, to improve the heat exchange efficiency of energy stake.

The metal tube of section and outlet pipe section is one-body molded.
Further, described metal tube is steel pipe, and described insulating tube is PPR pipe, insulating tube outer wrapping heat-preservation cotton.
Import pipeline section uses the pipeline of different materials with outlet pipe section, as it was previously stated, pile foundation pipe laying mainly has five types,
Single the most U-shaped, connect double-U-shaped (W type), parallel connection is double-U-shaped and ter is U-shaped and single-screw type, but no matter which kind of form, pipeline material is all
It is not changed in, and increasingly deeper in practice as pile foundation, because the Temperature Distribution of underground is about being distributed in trapezoid, underground
The deepest, low-temperature receiver, thermal source are the biggest, and the temperature difference is the biggest, in heat transfer medium (water or anti-icing fluid) enters this segment pipe of underground, it should
Use the big pipeline (such as steel pipe) of heat transfer coefficient, in order to make heat exchange fully carry out, when bottom medium arrives, temperature basic and
Identical outside pipe, but ascent stage, low-temperature receiver in soil, thermal source are relatively small, will carry out contrary heat exchange with medium, so should
The pipeline that this use heat transfer coefficient is less, such as with insulating tube (such as crosslinked polyethylene pipe PEX, chlorinated polyvinyl chloride pipe CPVC),
So can improve the efficiency of heat exchange.
This utility model, owing to using above scheme, has the advantage that
1. heat exchange is fully and energy loss is less;
