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

摘要

PROBLEM TO BE SOLVED: To provide a tube assembly with a stiff structure to survive insertion and removal of the tube assembly to and from a radiator for heavy duty equipment.SOLUTION: A tube assembly for use in a heat exchanger 1 includes a flat section with broad and flat opposing sides of a tube 2. Fin structures 10 are bonded to the broad and flat sides of the tube 2 in the flat section, and side sheets 11 are bonded to the opposite ends of the fin structures 10. The flat section of the tube 2 is located between cylindrical end sections 4 and 5 adapted to be inserted into grommets.
