These presentations were part of NARSA’s HD Conference hosted in Buffalo, New York September 17-19, 2015.
Radiator Math (Part 2)
In Part 2 of "Radiator Math," David Bienvenu explains how calculations are used to determine the triangular pitch of heat exchanger tubes, a fan blade angle, belt length using shaft centers, and pulley sizes or shaft centers knowing pulley sizes and belt length.
Radiator Math (Part 1)
All the math you ever needed to know you learned between kindergarten and 8th grade. But you probably forgot some of it! Radiator Service Co.'s David Bienvenu explains everyday product calculations and formulas that will reduce project time, increase efficiency, and help insure accuracy.
Core Materials & Design
Independent consulting engineer Mark Meller addresses the different types of metals and designs used in heat exchange and why. Materials covered include: copper, brass, aluminum, and steel. He explains fin and tube configurations and their applications as inline and staggered tube arrangements, staggered tube arrangements, bumped fins, louvered fins, lanced offset fins, serpentine fins and plat fins. The session also covers tube size and its impact on performance.
Practical Metal Forming & Fabrication Fundamentals
The presentation covers plate material selection (soft, hard, pickled, black, galvanized, SS 304 vs 316, gauges). It also breaks down bending for radiator tanks, side anchors and shrouds. Bending information will include selection of tool, blank length calculations, tolerance variations, radius selection, manual brake set-up, bending sequences as well considerations for single part, multi-part planning and duplication of parts.
