Affiliated technical field:
The present invention relates to a kind of heat exchanger, especially a kind of catheter type geothermal heat exchanger that can directly geothermal energy be sent to ground.
Background technology:
Shallow layer geothermal energy refers to that, within the scope of the following certain depth in earth's surface, temperature, lower than 25 degree, possesses the heat resource of the earth interior of value of exploiting and utilizing under current techniques economic condition, is a kind of renewable, clean energy resource.The direct utilization development of geothermal energy is very rapid at present, be widely used in industrial processes, the various aspects such as civil heating, bathing, medical treatment, agricultural greenhouse, field irrigation, soil are heated, aquaculture, its feeding, have received good economical and technical benefit benefit, have saved the energy.The direct utilization of geothermal energy, specification requirement is low, and equipment needed thereby is comparatively simple and easy.In directly utilizing the system of shallow layer geothermal energy, be all with pump, geothermal heat flow to be drawn up conventionally, use after becoming hot gas and hydrothermal solution by heat exchanger, need to consume a large amount of electric energy, cost is higher.
Summary of the invention:
The object of this invention is to provide a kind of needs takes out with pump, can directly geothermal energy be sent to the catheter type geothermal heat exchanger utilizing on the ground.
For achieving the above object, the technical solution used in the present invention is:
A kind of catheter type geothermal heat exchanger, comprise endothermic tube, heat pipe, radiating tube and heating agent, it is characterized in that: endothermic tube is in underground bosom, radiating tube on the ground, between endothermic tube and radiating tube, connect a heat pipe, endothermic tube is passed to heating agent after absorbing underground heat, and heating agent is carrying heat through heat pipe, in radiating tube, carry out heat exchange, through radiating tube, pass on the ground.
Catheter type geothermal heat exchanger according to described, is characterized in that: described endothermic tube is formed by easy heat conduction, the casting of noncorroding metal material, is deep in the underground water of pit shaft.
Catheter type geothermal heat exchanger according to described, is characterized in that: described heat pipe is aluminium-plastic pipe or plastic tube, and heat pipe outer surface is provided with heat-insulation layer, and the inner surface of heat pipe is provided with vertical groove.

The invention has the beneficial effects as follows, can directly utilize geothermal energy, specification requirement is low, and equipment needed thereby is comparatively simple and easy, is easy to manufacture and installs, and disposable input, can be used for a long time, reduces heating cost.Without any need for extrinsic motive, just underground heat energy can be sent in streams to a place on the ground, can be widely used in the various aspects such as civil heating, agricultural greenhouse, aquaculture, its feeding, safety, environmental protection, the saving energy.
Accompanying drawing explanation:
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is vertical section structure schematic diagram of the present invention.
Fig. 2 is scheme of installation of the present invention.
1 endothermic tube, 2 heat pipes, 3 radiating tubes, 4 heating agents, 5 heat-insulation layers, 6 pit shafts, 7 underground water in figure.
The specific embodiment:
As shown in Figure 1, 2, a kind of catheter type geothermal heat exchanger, comprise endothermic tube 1, heat pipe 2, radiating tube 3 and heating agent 4, it is characterized in that: endothermic tube 1 is in underground bosom, and radiating tube 3 on the ground, connects a heat pipe 2 between endothermic tube 1 and radiating tube 3, after absorbing underground heat, endothermic tube 1 passes to heating agent 4, heating agent 4 is carrying heat through heat pipe 2, carries out heat exchange in radiating tube 3, through radiating tube 3, passes on the ground.Endothermic tube 1 is formed by easy heat conduction, the casting of noncorroding metal material, is deep in the underground water 7 of pit shaft 6.Heat pipe 2 is aluminium-plastic pipe or plastic tube, and heat pipe 2 outer surfaces are provided with heat-insulation layer 5, and the inner surface of heat pipe 2 is provided with vertical groove.Radiating tube 3 is easy heat conduction, noncorroding metal pipe, a spherical metal shell of upper end welding, and inner surface is provided with vertical groove.Heating agent 4 is high for critical-temperature, and the liquid refrigerant that condensation temperature is low, packs in catheter type geothermal heat exchanger, is full of whole endothermic tube 1.
Principle and operating process: the several pit shafts 6 of subdrilling in the booth heating at needs or house, pit shaft 6 degree of depth can be tens meters, tens meters or hundreds of rice, to get into underground water 7, are advisable.Then the endothermic tube of catheter type geothermal heat exchanger 1 one end is inserted in pit shaft 6, submerge in underground water 7, radiating tube 3 is basseted and will between pit shaft mouth and catheter type geothermal heat exchanger, seal up.With air exhauster, the air in catheter type geothermal heat exchanger is extracted out, added appropriate heating agent 4 to make cold-producing medium.In cold winter, because surface temperature is low, subsurface temperature is higher, exists the very large temperature difference between the two.When heating agent 4 is vaporized after the interior absorption heat of endothermic tube 1, the steam of high temperature rises along heat pipe 2, arrives after radiating tube 3, and because radiating tube 3 temperature is around lower, the steam of high temperature is cooled, liquefies, and emits heat.The vertical slot channel resorption heat pipe 1 of heating agent 4 after liquefaction on radiator 3 and heat pipe 2 inner surfaces, absorbs heat at endothermic tube 1 place and vaporizes, and becomes high-temperature steam and rises.So ceaselessly carry out heat exchange, underground heat energy is delivered on the ground endlessly, the temperature in booth or house is constantly raise.
