ABSTRACT:
An improved method of making a cross-flow heat exchange surface of modified perforated or expanded metal is described. One form comprises multiple layers of the metal, stacked and laminated together by brazing. Advance in the state-of-the-art is the novel manufacturing process designed to optimize heat transfer at reduced manufacturing cost. Prior knowledge on manufacture of porous metal laminates has principally involved the weaving, layering, and bonding of wire meshes. This process obviates the need for weaving and results in a more rigid, open, low-fouling structure suitable to withstand the rigors of vigorous cleaning. The unique characteristic of this exchanger lies in the design of the lamina. A lamina comprises two expanded metal areas with a section of solid metal between. The purpose of the solid section is to provide a thermal conduction path between the two open sections. It also serves as a partition to separate the two gas streams. The expanded sections provide an effective heat exchange surface for a regenerative heat system.
