[0001] Apparatus for manufacturing geothermal heat exchanger [0002]

The present invention relates to a method for forming a geothermal pipe, and more particularly, to a method for continuously forming a geothermal pipe by continuously supplying pellet fuel through a molten portion and continuously discharging a liquid material for forming the geothermal pipe, The present invention also relates to a geothermal pipe forming system that can cut a geothermal tube into a predetermined length through a cut-out portion and a wind-up portion so as to be rolled up and stored, as well as to be supplied to a workplace.

Generally, geothermal energy refers to the heat energy that the earth has, but recently geothermal energy is often used to refer to the heat of the earth that can be discovered, developed, or developed by humans. The origin of geothermal heat is about 83% due to the collapse of radioactive isotopes inside the crust and mantle, about 17% due to the release of mantle and its lower heat, It is estimated that about 40% of the geothermal heat in the surface is due to crust. Therefore, the lower the temperature, the higher the temperature, which is called the geothermal gradient or geothermal gradient. The depth that can be drilled by modern drilling technology, that is, the average temperature increase rate up to 10 km is about 25 ~ 30 ℃ / km.

Technology for utilizing geothermal energy resources can be classified into power generation (indirect use) technology using geothermal fluid (steam and geothermal water) at 150 ° C or more and direct utilization technology using geothermal water at a lower temperature for district heating.
