Abstract

La présente description décrit un échangeur de chaleur métal liquide - air, comprenant un flasque étendu et formé dans une direction verticale, une chambre supérieure prévue au niveau d'une partie supérieure d'une circonférence interne du flasque pour loger et décharger un métal liquide introduit par une branche chaude, une chambre inférieure prévue au niveau d'une partie inférieure d'une circonférence interne du flasque, et raccordée à une branche froide pour décharger un métal liquide, un tube d'entrée d'air configuré pour former une première trajectoire d'écoulement dans une direction ascendante pour inhaler l'air, un tube de sortie d'air configuré pour former une seconde trajectoire d'écoulement dans une direction ascendante pour décharger l'air, un tube interne raccordé au tube d'entrée d'air et au tube de sortie d'air, et une pluralité de tubes de transfert de chaleur enroulés dans une direction hélicoïdale dans un premier espace annulaire entre une circonférence externe du tube interne et une circonférence interne du flasque, et dont les deux parties d'extrémité sont raccordées à la chambre supérieure et à la chambre inférieure pour laisser s'écouler le métal liquide, dans lequel l'air est inhalé par la première trajectoire d'écoulement et déchargé par la seconde trajectoire d'écoulement pour refroidir le métal liquide à l'intérieur du tube de transfert de chaleur tout en passant par le premier espace annulaire.The present disclosure describes a liquid metal-air heat exchanger, comprising an extended flange and formed in a vertical direction, an upper chamber provided at an upper part of an inner circumference of the flange for accommodating and discharging an introduced liquid metal. by a hot leg, a lower chamber provided at a lower part of an internal circumference of the flange, and connected to a cold leg for discharging a liquid metal, an air inlet tube configured to form a first path flow path in an upward direction for inhaling air, an air outlet tube configured to form a second flow path in an upward direction to discharge air, an inner tube connected to the inlet tube of air and to the air outlet tube, and a plurality of heat transfer tubes wound in a helical direction in a first annular space between an outer circumference of the tube internal and an internal circumference of the flange, and the two end portions of which are connected to the upper chamber and the lower chamber to flow the liquid metal, into which air is inhaled by the first flow path and discharged through the second flow path to cool the molten metal inside the heat transfer tube while passing through the first annulus.
