High-capacity geothermal exchange device using river side underground water

摘要

The present invention relates to a high-capacity geothermal exchange device using riverside underground water. The riverside underground water flows into an inner space of a cylindrical pipe located in a well, and the underground water collected to a collection space between the cylindrical pipe and the well is discharged into the ground by a lower horizontal excavation line. The multiple lower horizontal excavation lines are installed in all directions in the lower part of the well and discharge the underground water flowing into the collection space into the ground outside the well. Multiple upper horizontal excavation lines are installed in the upper part of the lower horizontal excavation line and are installed in the all directions on the circumference of the well. Therefore, a supply path of the riverside underground water is formed by a lifting line, the inner space of the cylindrical pipe, and the upper horizontal excavation line. A discharge path of the underground water collected by a collection line, the collection space between the cylindrical pipe and the well, and the lower horizontal excavation line is formed. A collection path of the underground water passing through a heat exchange unit and the supply path of the underground water is completely blocked. So, thermal interference between the collection path and the supply path of the underground water is minimized, and heat efficiency is maximized.
