HEAT EXCHANGER TUBE, HEAT EXCHANGER TUBE ASSEMBLY, AND METHODS OF MAKING THE SAME

摘要

A tube assembly used in a heat exchanger arranges a first crease pin structure between a wide flat surface of a tube and a side sheet. The tube arranges a second crease pin structure between the other wide flat surface of the tube and the other side sheet. The present invention is provided to touch a ridge unit and a valley unit of the crease pin structure to the side sheet and the wide flat surface by applying compression force to a faced surface of the side sheet. Therefore, the assembly is brazed.
