Description
Technical Field
[0001] This utility model relates to the field of geothermal heat exchanger technology, specifically to an underground portable geothermal energy heat exchanger. Background Technology
[0002] Geothermal heat exchangers are devices that utilize the relatively stable characteristics of underground soil and groundwater at constant temperatures to exchange heat with the interior of buildings through pipe systems or groundwater buried deep around the buildings. As a highly efficient and convenient geothermal energy utilization device, the underground portable geothermal heat exchanger is of great significance in energy conservation, emission reduction, and improving energy utilization efficiency.

[0004] To address the issues of poor heat exchange performance, low heat exchange efficiency, and inconvenient installation of geothermal heat exchangers, existing technologies employ a spiral inlet pipe positioned within the cavity between the outer and inner pipes to extend the indirect contact time between the heat exchange medium and the geothermal energy, thereby improving the heat exchange effect. Heat-conducting plates guide the geothermal energy towards the heat exchange medium, further enhancing heat exchange efficiency. However, these methods still present challenges. The presence of impurities in the heat medium flowing within the pipes can cause corrosion, potentially reducing the pipes' lifespan. Utility Model Content

The water then flows out through the water outlet 16.
[0028] Example 2
