Abstract[English]
The present disclosure relates to systems and methods of geothermal energy production using a dual thermosiphon heat exchange system. In one system two working fluids in which a thermosiphon flow is induced to recover thermal energy from depth. The system has a subterranean heat exchanger that is formed into an underground formation by drilling, and which is flooded with a first working fluid. Heat from the formation is transferred into the first working fluid. A recovery loop extends from the earth's surface and into the heat exchanger and carries a second working fluid. Heat from the formation is transferred into the first working fluid, and heat from the first working fluid is transferred into the second working fluid. The heat flow from the formation into the first working fluid and from the first working fluid into the second working fluid causes a thermosiphon flow in the working fluids.[French]
La présente divulgation concerne des systèmes et des procédés de production d'énergie géothermique à l'aide d'un système d'échange de chaleur à thermosiphon double. Selon un système, deux fluides de travail, dans lesquels un écoulement à thermosiphon est provoqué, permettent de récupérer de l'énergie thermique à partir des profondeurs. Le système comporte un échangeur de chaleur souterrain formé dans une formation souterraine par forage, et lequel est rempli d'un premier fluide de travail. La chaleur émanant de la formation est transférée au premier fluide de travail. Une boucle de récupération s'étend à partir de la surface de la terre et vers l'échangeur de chaleur, et achemine un second fluide de travail. La chaleur émanant de la formation est transférée au premier fluide de travail, et la chaleur émanant du premier fluide de travail est transférée au second fluide de travail. Le flux de chaleur émanant de la formation vers le premier fluide de travail, et du premier fluide de travail vers le second fluide de travail, provoque un écoulement à thermosiphon dans les fluides de travail.
