Pinless Multi-tube type Double-tube Heat Exchanger Equipped with Heat Exchage Tube

摘要

The present invention (design) is for assembling a tube sheet (tube plate) and a tube (heat exchange pipe) in a finless type multi-pipe double pipe heat exchanger equipped with a fitting device for coupling a tube sheet (tube plate) and a tube (heat exchange pipe). It relates to a pinless type multi-tube double tube heat exchanger assembled with a fitting device. More specifically, it is possible to separate and assemble the heat exchange tube to facilitate repair and replacement of the heat exchange tube, as well as to facilitate cleaning of the heat exchange tube. It relates to a finless type multi-tube double tube heat exchanger that simplifies the structure by separating and cleaning it to facilitate maintenance and cleaning.
