Abstract
A tubular heat exchanger includes an upper tube plate box, a lower tube plate box, a plurality of heat exchange tubes, and a pressure bolt. Each heat exchange tube includes an inlet end and an outlet end opposite to the inlet end, the inlet end passes through the upper tube plate box, the outlet end passes through the lower tube plate box, the first sealing rubber is filled in a gap between the plurality of heat exchange tubes and the upper tube plate box, and the second sealing rubber is filled in a gap between the plurality of the heat exchange tubes and lower tube plate box. The pressure bolt is located between the upper tube plate box and the lower tube plate box. The present application also relates to a packaging method of the tubular heat exchanger.
