Abstract
(EN) A groundwater heat exchanger (102) includes a distributor (140), a collector (144), a plurality of heat exchange pipes (134), and a housing (180). The distributor includes a first interior chamber (142) and a first port (130). The collector includes a second interior chamber (146) and a second port (132). Each heat exchange pipe includes a first end (141) attached to the distributor and a second end (143) attached to the collector, and defines a fluid passageway between the first and second interior chambers. The housing surrounds the heat exchange pipes and defines a groundwater passageway along the heat exchange pipes that is configured to receive a groundwater flow (138). In one example, a loop fluid flow (112) received at the first port flows into the first interior chamber, then flows from the first interior chamber to the second interior chamber through the plurality of heat exchange pipes, and flows from the second interior chamber out the second port.
(FR) Un échangeur de chaleur (102) d'eau souterraine comprend un distributeur (140), un collecteur (144), une pluralité de tuyaux d'échange de chaleur (134) et un boîtier (180). Le distributeur comprend une première chambre intérieure (142) et un premier orifice (130). Le collecteur comprend une seconde chambre intérieure (146) et un second orifice (132). Chaque tuyau d'échange de chaleur comprend une première extrémité (141) fixée au distributeur et une seconde extrémité (143) fixée au collecteur, et délimite un passage de fluide entre les première et seconde chambres intérieures. Le boîtier entoure les tuyaux d'échange de chaleur et délimite un passage d'eau souterraine le long des tuyaux d'échange de chaleur qui est conçu pour recevoir un écoulement d'eau souterraine (138). Selon un exemple, un écoulement de fluide en boucle (112) reçu au niveau du premier orifice s'écoule à l'intérieur de la première chambre intérieure, puis s'écoule de la première chambre intérieure vers la seconde chambre intérieure à travers la pluralité de tuyaux d'échange de chaleur, et s'écoule de la seconde chambre intérieure vers l'extérieur à travers le second orifice.
