КОНСТРУКЦИЯ ЭЛЕМЕНТА ТЕПЛООБМЕННИКА С ПЛАСТИНЧАТЫМИ РЕБРАМИ

Изобретение предназначено для теплообменников с пластинчатыми ребрами и может быть использовано в качестве рекуператора. Множество устойчивых к давлению отдельных элементов теплообменника соединены между собой посредством пайки с применением разделительных пластин с образованием единого теплообменника с пластинчатыми ребрами. Каждый отдельный элемент теплообменника содержит все особенности цельного противоточного теплообменника с входным и выходным отверстиями, воздухораспределительными коллекторами и теплопреобразовательными ребрами, спаянными в единый блок. Затем элементы объединяются в блок и рельефные фланцы свариваются вместе. Множество блоков затем свариваются вместе с образованием теплообменника. При таком способе сборки и при таком выполнении отдельного элемента и теплообменника в целом достигается полное сцепление элементов теплообменника и повышается надежность элементов теплообменника и самого теплообменника. 3 с. и 8 з.п. ф-лы, 7 ил.
