Description

Technical Field

[0001] The invention relates to the technical field of geothermal power generation, and in particular to a detachable geothermal power generation module. Background Art

[0002] The development and utilization of geothermal energy is of great significance for adjusting the energy structure, saving energy and reducing emissions. Existing geothermal power generation technology usually requires water to be poured into the ground, and water is used as a medium to bring heat to the ground for subsequent power generation. However, during the transportation of the heat source, the heat source contacts the heat pipe, causing part of the heat in the heat source to be transferred to the heat pipe. For longer pipes, this heat loss is more serious. The deep geothermal in-situ power generation technology proposed for the development and utilization of deep geothermal energy uses temperature difference power generation technology, which can directly convert underground thermal energy into electrical energy in-situ underground.

[0003] Generally speaking, the more efficient the heat transfer between the heat source and the hot end surface of the semiconductor power generation element and between the cold end surface of the semiconductor power generation element and the cold source (such as air, water), or the smaller the heat transfer resistance, the greater the temperature difference between the hot and cold end surfaces of the semiconductor power generation element, and the higher the power generation efficiency. In addition, in order to maximize the effective net power generation of the semiconductor power generation element, it is best not to use additional active heat transfer methods (such as using fans or pumps, etc.) to maximize the temperature difference between the hot and cold end surfaces. How to achieve this goal depends on the installation structure of the power generation module and the fit between the heat source and the power generation module. Summary of the invention
