Abstract
The utility model relates to the technical field of heat exchange equipment and provides a heat exchange tube. The heat exchange tube is of a double layer enclosed sleeve structure which comprises a silicon carbide outer tube and a silicon carbide inner tube. An air outlet is arranged in the silicon carbide outer tube. An air inlet is arranged in the silicon carbide inner tube. The silicon carbide inner tube penetrates through the top end of the silicon carbide outer tube and is provided with an inner tube extending mechanism. The air inlet is arranged on the tail end of the inner extending mechanism. A separating mechanism is arranged at the lower end of the air outlet position of the silicon carbide outer tube. The silicon carbide outer tube is divided into a silicon carbide outer tube upper segment and a silicon carbide outer tube lower segment through the separating mechanism. The lower end portion of the silicon carbide outer tube lower segment and the lower end portion of the silicon carbide outer tube upper segment form a heat exchange cavity. The heat exchange tube is of the double layer enclosed sleeve structure which comprises the silicon carbide outer tube and the silicon carbide inner tube. Silicon carbide materials improve heat exchange efficiency and service life of the heat exchange tube.
