Method For Manufacturing Tube And Fin Heat Exchanger With Reduced Tube Diameter And Optimized Fin Produced Thereby

US Patent:

Filed:

Jun 15, 2009

Appl. No.:

12/484895

Inventors:

Pei Pei Chen - Houston TX, US

Abstract:

An improved method for manufacturing tube and fin heat exchangers that, according to a preferred embodiment, includes a process for increasing the stiffness and rigidity of heat exchanger fins. Stiffer fins have a greater tendency to maintain proper alignment within a stack of fins, which aids in lacing long stacks of fins with small (e.g., 5 mm) diameter tubing. Preferably, fin stiffness is increased by forming a plurality of longitudinal ribs within the fin during the fin stamping process. More preferably still, two ribs for each longitudinal row of collared holes are provided. The preferred embodiment also includes a slotted heat exchanger fin that is dimensioned and arranged for optimized thermodynamic performance when used with small diameter tubing, thus reducing the space required for a given heat exchanger system.
