In the environment of energy conservation and emission reduction, the popularization and application of renewable energy technology is a necessary trend of social and economic development. Ground source heat pump systems have been popularized and popularized in the fields of heating and refrigeration of buildings due to mature technology and good energy conservation and environmental protection. Is also a typical renewable energy technology advocated and encouraged by the country and conforms to the industrial policy of the country.

The ground source heat pump is a device for transferring low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy) into shallow land energy. Usually, the ground source heat pump consumes 1kWh of energy, and users can obtain heat or cold above 4.4 kWh. The ground source heat pump system transfers heat or cold in the underground soil to a required place, and also utilizes the huge heat storage and cold storage capacity of the underground soil, the ground source transfers the heat from the underground soil to a building in winter, and transfers the underground cold to the building in summer, so that a cold-heat circulation system is formed in one year, and the functions of energy conservation and emission reduction are realized.

In actual operation, the underground hole is drilled vertically through the well drilling machine, then the ground source heat pump double-U pipe fitting drives the heat exchange pipe to be buried in the drilled well, finally, the filler is backfilled into the well and into a gap between the well and the heat exchange pipe, the ground source heat pump double-U pipe fitting in the prior art is mostly a square body, the double-U pipe fitting of the square body has the problems of high processing cost, less internal water storage capacity and the like, and the resistance problem of the pipe fitting in the well can not be effectively reduced when the well is drilled.

SUMMERY OF THE UTILITY MODEL

To the deficiency that exists among the prior art, the utility model provides a two U pipe fittings of ground source heat pump has the advantage that processing is convenient and reduce the resistance when going into the pit.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a two U pipe fittings of ground source heat pump, includes tube head and body, tube head and body fixed connection, set up two parallel and mutually independent water trough in the body, still set up two intercommunication grooves that correspond and link up with the water trough in the tube head, the one end that the body deviates from the tube head still fixedly is equipped with four connecting pipes, four two liang of a set of connecting pipes respectively with two water trough through connections in the body.

The working principle is as follows:

the utility model relates to a two U pipe fittings of ground source heat pump, mainly used fix the heat exchange tube and carry out inside water source exchange, and drive the heat exchange tube and bury underground.

When the connecting pipe is used, the pipe head and the pipe body are firstly subjected to hot melting and are fixedly connected, so that two connecting grooves in the pipe head are respectively communicated with two water passing grooves in the pipe body.

After fixed the completion, with the inlet channel of heat exchange tube and outlet conduit respectively with the connecting pipe fixed connection of same group, all be connected the back with two sets of connecting pipes with the heat exchange tube, through inciting somebody to action the utility model discloses drive the heat exchange tube and bury in the well that the rig made.

The beneficial effects obtained are as follows:

because the intercommunication groove in the tube head and the water service tank through connection in the tube body, effectual messenger the utility model discloses inside water storage space improves greatly.

Because inside is equipped with two spread grooves and two water service grooves and forms independent space each other, two sets of connecting pipes respectively with two independent water service grooves through connection, set up like this and can effectually make two sets of heat exchange tubes independent work respectively.

FIG. 2 is a schematic view of the overall structure of the cartridge of FIG. one;

fig. 3 is a schematic view of the overall structure of the tube in fig. two.

In the drawings, wherein: 1. a tube head; 2. a tube body; 3. a water trough; 4. a communicating groove; 5. a connecting pipe; 6. an extension section; 7. A first shrink groove; 8. a second shrink slot; 9. a first drainage tank; 10. a second water discharge tank; 11. and (6) rounding off.

Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

Example (b):

referring to fig. 1-3, the utility model relates to a two U pipe fittings of ground source heat pump, including tube head 1 and body 2, tube head 1 and body 2 fixed connection, tube head 1 is the circular shape columnar body with body 2, and this tube head 1 extends and forms frustum-shaped extension section 6 to the direction of keeping away from body 2. Establish to this kind of cylindricly with tube head 1 and body 2, compare in square body can effectual reduction two U pipe fittings receive the resistance of water or earth when the pit to promote work efficiency. Two parallel and mutually independent water service grooves 3 are arranged in the pipe body 2, two communicating grooves 4 which correspond to and run through the water service grooves 3 are also arranged in the pipe head 1, four connecting pipes 5 are fixedly arranged at one end of the pipe body 2 which deviates from the pipe head 1, and the connecting pipes 5 are connected with the two water service grooves 3 in the pipe body 2 in a penetrating way in a pairwise mode. A plurality of first shrink grooves 7 have still been seted up downwards at 2 tops of body and between two limbers 3, a plurality of second shrink grooves 8 have still upwards been seted up to tube head 1 bottom and between two intercommunication grooves 4. Be equipped with first shrink groove 7 and second shrink groove 8 respectively in body 2 and tube head 1 and can effectually prevent that tube head 1 and body 2 from taking place great deformation because the inner wall is thicker messenger tube head 1 and body 2 after the injection moulding cooling. Still seted up a plurality of first water drainage tank 9 on the lateral wall of body 2, still seted up a plurality of second water drainage tank 10 with a plurality of first water drainage tank 9 one-to-one on the lateral wall of tube head 1. Seted up first water drainage tank 9 and second water drainage tank 10 on tube head 1 and body 2, can be further reduce the resistance that two U pipe fittings received when descending through first water drainage tank 9 and second water drainage tank 10, further promotion work efficiency. Four the inner wall and the outer wall of the pipe orifice circumference of the end of the pipe body 2 far away from the connecting pipe 5 are both provided with a fillet 11. Set up like this, can effectually have a connecting pipe 5 of fillet 11 and a connecting pipe 5 combination that does not have the chamfer through homonymy to connect the inlet channel and the outlet conduit of outside heat exchange tube, prevent even wrong messenger's pipe fitting and scrap.

The working principle is as follows:

when in use, one end of the pipe head 1 far away from the extension section 6 and one end of the pipe body 2 far away from the connecting pipe 5 are subjected to hot melting and fixed connection, so that the two communicating grooves 4 in the pipe head 1 are respectively communicated with the two water passing grooves 3 in the pipe body 2. After the fixing is finished, a connecting pipe 5 with a fillet 11 and a connecting pipe 5 without a fillet are combined at the same side, and the water inlet pipeline and the water outlet pipeline of the heat exchange pipe are respectively and fixedly connected with the connecting pipes 5 in the same group. After all being connected two sets of connecting pipes 5 with the heat exchange tube, again through will the utility model discloses drive the heat exchange tube and bury in the well that the well rig was made.
