US 6,629,561 B2 · Module for a heat exchanger having improved thermal characteristics

Abstract

A module for a heat exchanger comprises a first generally planar member having a first opening at an opposite end with respect to a second opening. A second generally metallic planar member has a first opening at an opposite end with respect to a second opening. The first generally planar member may be aligned with the second generally planar member to form a cavity in communication with the first opening and the second opening. A pattern of elevated regions may extend from the first generally planar member and the second generally planar member. The pattern of elevated regions has a regional longitudinal axis that is tilted with respect to a reference longitudinal axis of at least one of the first generally planar member and the second generally planar member. A flow longitudinal axis may be tilted with respect to the reference longitudinal axis to facilitate a cross-flow of the fluid with respect to the elevated regions.

Dependent claims

A module for a heat exchanger, the module comprising:

a first generally planar member having a first opening at an opposite end with respect to a second opening;
a second generally planar member having a first opening at an opposite end with respect to a second opening, the first generally planar member being oriented with respect to the second generally planar member to form a cavity in communication with the first opening and the second opening;
and
a pattern of elevated regions having a pattern longitudinal axis that is tilted with respect to a reference longitudinal axis of at least one of the first generally planar member and the second generally planar member, wherein the pattern of elevated regions comprises a matrix of rows and columns of elevated regions wherein adjacent rows are offset from one another by an offset distance that is less than a spacing between adjacent elevated regions within a row.

A heat exchanger comprising:

a first pair of generally planar members, each having a first opening at an opposite end with respect to a second opening, the first pair of generally planar members joined to one another at least near their perimeters to form a first cavity in communication with the first opening and the second opening;
a second pair of generally planar members, each having a first opening at an opposite end with respect to a second opening, the second pair of generally planar members joined to one another at least near their perimeters to form a second cavity in communication with the first opening and the second opening, the first cavity cascaded with the second cavity;
and
