Abstract
Теплообменник типа «труба в трубе», во внутренней трубе и в межтрубном пространстве которого установлены винтовые вставки, отличающийся тем, что внутреннее пространство внутренней трубы и межтрубное пространство между внутренней и наружной трубами представляют из себя винтовые полости, образованные стенками труб и винтовыми вставками, установленными таким образом, что внутренняя винтовая вставка соединена возможно более плотно, преимущественно с помощью сварки или пайки, с внутренней поверхностью внутренней трубы, винтовая вставка в межтрубном пространстве соединена таким же образом с наружной поверхностью внутренней трубы и с внутренней поверхностью наружной трубы, причем, материалы внутренней трубы, винтовых вставок и мест стыков винтовых вставок со стенками внутренней трубы имеют возможно меньшее термическое сопротивление, а потоки жидкостей во внутренней трубе и в межтрубном пространстве двигаются по винтовым спиралям во встречных направлениях.A pipe-in-pipe type heat exchanger with screw inserts installed in the inner pipe and in the annular space, characterized in that the inner space of the inner pipe and the annular space between the inner and outer pipes are screw cavities formed by pipe walls and screw inserts installed so that the inner screw insert is connected as tightly as possible, mainly by welding or soldering, with the inner surface of the inner pipe, screw insert the annular space is connected in the same way with the outer surface of the inner pipe and with the inner surface of the outer pipe, moreover, the materials of the inner pipe, screw inserts and the joints of the screw inserts with the walls of the inner pipe have the lowest possible thermal resistance, and the fluid flows in the inner pipe and in the annular space moving in helical spirals in opposite directions.
