Efficient geothermal energy heat exchange system

Abstract

The invention relates to an efficient geothermal energy heat exchange system. The efficient geothermal energy heat exchange system comprises a booster fan, an air amplifier, an air vortex tube, a draft tube, a bearing column, heat exchange plates, temperature sensors, a thermal energy conversion device and a control circuit. The bearing column is of a hollow tubular structure, and the heat exchange plates are embedded in the bearing column and communicate with the air vortex tube. The air vortex tube is connected with the booster fan, and the booster fan communicates with the air amplifier. The air amplifier separately communicates with the outlet ends of the heat exchange plates and the thermal energy conversion device.

[0002] At present, in the development and utilization of geothermal energy, one of the main ways is to set up heat exchange equipment in geothermal wells, and then transport medium such as low-temperature water to the geothermal well on the surface, make it return to the surface after being heated by geothermal heat, and communicate with it. The corresponding heat exchange equipment performs heat energy exchange to complete the needs of geothermal collection operations. Although this method can meet the needs of geothermal collection operations, on the one hand, the structure of the geothermal collection system is complex, and it needs to be equipped with booster pumps, circulation pumps, and cooling systems. devices and other equipment, resulting in relatively large equipment construction investment costs and operation and maintenance costs for the geothermal collection system. Poor, the heat exchange efficiency is relatively low, so it is impossible to collect heat energy in the lower temperature position in the formation, which causes waste of resources, but also leads to the current geothermal well depth is often large, and the distribution position is also greatly affected In addition, the heating and cooling speed of the water body during operation is relatively slow, which cannot meet the needs of efficient geothermal collection, and in geothermal collection, due to factors such as evaporation, it is easy to cause a large amount of water loss and waste. , so in view of this situation, it is urgent to develop a new geothermal heat exchange equipment to meet the needs of actual use
