Abstract
Abstract A baffle array or assembly comprised of a plurality of longitudinal spacer rods and baffle plates is described. The spacer rods have a body portion and a protruded portion along their length. The protruded portion has a plurality of slots therein at spaced intervals. The baffle plates have peripheral openings therein adapted to receive the body portion of the spacer rods. The baffle plates and spacer rods are assembled into an array by positioning the baffle plates at right angles to the spacer rods, passing the spacer rods through the peripheral openings in the baffle plates and engaging the thicknesses of the baffle plates within the slots in the protruded portions of the spacer rods.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
An internal baffle array for a heat exchange unit comprising a plurality of longitudinal spacer rods, each having a body portion and a protruded portion along the length thereof, said protruded portions having a plurality of slots therein at spaced intervals, and a plurality of baffle plates positioned at right angles to said spacer rods, said baffle plates each having a plurality of openings at the periphery thereof adapted to receive at least the body portions of said rods, with said spacer rods passing through the openings in said baffle plates and holding the baffle plates in desired spacing relationship by engagement of the widths of said plates within said spaced slots in said protruded portions of said rods upon rotations of the rods.
Claim 2
Dependent Claim
124 words
An internal baffle array for a heat exchange unit comprising a plurality of longitudinal spacer rods, each having a body portion and a protruded portion along the length thereof, said protruded portions having a plurality of slots therein at spaced intervals, and a plurality of baffle plates positioned at right angles to said spacer rods, said baffle plates each having a plurality of openings at the periphery thereof adapted to receive at least the body portions of said rods, with said spacer rods passing through the openings in said baffle plates and holding the baffle plates in desired spacing relationship by engagement of the widths of said plates within said spaced slots in said protruded portions of said rods upon rotations of the rods.
Claim 3
Dependent Claim
24 words
A baffle array according to claim 1 which is positioned within a heat exchanger shell, against the interior walls of which the baffles fit.
Claim 4
Dependent Claim
17 words
A baffle array according to claim 1 which contains between two and about one hundred baffle plates.
Claim 5
Dependent Claim
19 words
A baffle array according to claim 1 wherein the baffle plates have baffle cuts of up to 50 percent.
Claim 6
Dependent Claim
33 words
A baffle array according to claim 1 wherein the longitudinal spacing rods have body portions which are approximately circular in cross-section and have protruded portions which are approximately square or rectangular in cross-section.
Claim 7
Dependent Claim
35 words
A baffle array according to claim 5 wherein the spaced slots are substantially only in the protruded portions of the longitudinal spacing rods and are of a width about the thickness of the baffle plates.
Claim 8
Dependent Claim
71 words
A baffle array according to claim 1 wherein the openings in the baffle plates at the peripheries thereof are of a substantially circular shape with an extension from such circular opening at the periphery to accommodate at least a part of the protruded portion of the longitudinal spacer rod to facilitate insertion of such rods through such openings in a plurality of such baffle plates during the assembly of such array.
