Abstract

An intermeshing passage manifold is a device for subdividing each of two passages of ducts connected to it into multiple adjacent separate intermeshed passages. The intermeshing passage manifold is to be used for heat exchangers and fluid mixing devices in order to minimize pressure (energy) losses and to satisfy geometric constraints in many applications. The intermeshing passage manifold consists of a number of manifold sections adjacent in an end-to-end manner. Each of the manifold sections consists of a number of passage modules adjacent in a side-by-side manner. Each passage module consists of two passages; the orientation of these passages at one end of a module is at right angles to the orientation of the passages at the other end of the module, however, the cross-section shape of the module remains the same throughout its length. The change in orientation of the passages within the passage module is effected by means of a flowguide partition which is a multiplanar and/or contoured partition bound by six lines, each of these lines lying in one of each of the four enveloping side partitions and in each of the end planes of the passage module. Successive manifold sections have increasing numbers of passage modules so that each passage module of a manifold section is aligned with an integral number of passage modules of the following manifold section.

An intermeshing passage manifold adapted for connecting ducts each conveying different fluids to the ends of a heat exchanger core comprising;

(a) one primary and an integral number of secondary manifold sections adjacent successively in an end-to-end manner
(b) each of said manifold sections comprising a plurality of passage modules adjacent in a side-by-side manner
(c) each of said passage modules including a pair of similar twisted passages enveloped by four module side partitions to maintain the shape of the cross-sections of the module similar along the length thereof
(d) said twisted passages in each of said modules being separated by a flowguide partition;
each of said flowguide partitions comprising a continuous surface bound by six adjoining lines, one of each of said lines being contained within each of the four module side partitions and each of the two end planes of said module, each of said flowguide partitions serving to transform the cross-sectional configuration of said pair of twisted passages so that the orientation of said cross-sectional configuration of said twisted passages at one end of said module end planes is substantially at right angles to the orientation of said cross-sectional configuration of said twisted passages at the other of said module end planes
(e) said primary manifold section having one layer of passage modules oriented so that when said two ducts are connected to it at one end, the two passages defined by said ducts are subdivided into separate adjacent intermeshed passages at the other end
(f) each of said secondary manifold sections having a plurality of layers of passage modules adjacent in a side-by-side manner
(g) each of said secondary manifold sections contains a larger number of passage modules than the preceding manifold section such that an integral number of passage modules of each of the secondary manifold sections is aligned and congruent with each of the passage modules of the preceding manifold section
(h) said passage modules being oriented so that the passages at the end of the manifold which is opposite to that end to which the said ducts are connected are separate adjacent intermeshed passages.
