Abstract
Abstract Apparatus for use in a heat exchange unit having wound fin tubing including a tube support assembly having a tube support and a rod for securing runs of wound fin tubing therebetween. The rod is mounted to the tube support in rod slots providing a snap fit arrangement. The entire tube support assembly is designed for use for mounting a peripherally encasing heat exchanger that is tapered to a vertical partition.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
211 words
A heat exchanger assembly which comprises: a heat exchanger formed from a plurality of loops of wound fin tubing including a projecting fin material extending from a base tube, said loops being located in a circumferentially extending pattern wherein adjacent loops are displaced relative to each other to provide a tapered configuration; and at least one tube support assembly for securing the loops in the tapered configuration including a support member having a partition end portion and an orifice end portion with tube securing portions therebetween which define tube receiving openings for the receipt of the individual loops of tubing, at least one extension portion projecting at a non-perpendicular angle beyond the tube securing portion and defining a rod slot, another extension portion projecting perpendicular to and beyond said tube securing portion, a rod having a body portion extending the length of the support member and being sized to only snap fit and be secured within the rod slot of the extension portion and having a threaded portion located at an angle to said body portion and coacting with said partition end portion and said another extension portion, said rod securing the loops of tubing in the tube receiving openings by engaging the loops between the rod and the support member.

Claim 3
Dependent Claim
58 words
The apparatus as set forth in claim 1 wherein the extension portion of the support member further comprises projections which partially define the rod slot and which are spaced apart less than the diameter of the rod whereby upon insertion of the rod into the rod opening the projections act to maintain the rod within the rod slot.
Claim 4
Dependent Claim
19 words
The apparatus as set forth in claim 1 wherein each end portion including means to secure the rod therein.
Claim 5
Dependent Claim
88 words
The apparatus as set forth in claim 3 wherein the support member and heat exchanger are mounted to a vertical partition at an angle inclined from horizontal, said partition end portion being angled from the tube securing portions and defining an opening for the rod therethrough which is horizontal to the partition, said threaded portion extending through the opening in the partition end portion and the body portion being secured in the at least one extension portion generally parallel to the tube securing portions of the support member.
Claim 6
Dependent Claim
24 words
The apparatus as set forth in claim 4 wherein the rod may be secured to the partition to thereby support the heat exchanger assembly.
