Abstract:

A heat exchanger of the plate-fin type has fins of one metal brazed to a plate made of a different metal for use in oil coolers, condensers, evaporators, and the like. The distortion-prone titanium fins of conventional heat exchangers may be replaced with another metal, such as a stainless steel or a nickel based alloy to provide a structure that is resistant to crushing at the brazing temperature. Fluid or air flow resistance (pressure drop) through the heat exchanger may also be improved if the selected fin metal forms better fin shapes and has fewer burrs than conventional titanium fins. The replacement material may also improve the heat transfer performance of the heat exchanger if the selected fin metal has higher thermal conductivity than titanium.

Abstract:

A mattress is configured to have multiple zones made of springs configured in different orientations. A first zone of the mattress has springs packed in a first pattern, and a second zone has the springs packed in a second pattern that is different from the first pattern. The springs in the first zone and the second zone are the same type of springs. By packing the same springs in different patterns, the zones can have different firmness levels.
