Abstract
Abstract Apparatus for use in a heat exchange unit having wound fin tubing includes a tube support having a vertical portion and multiple lateral portions, each lateral portion having an opening therein. A support tube is inserted through the openings in the lateral portions of the tube support such that runs of wound fin tubing are secured between the tube support and the support tube. A run support portion of the tube support may additionally define notches for securing the various runs of wound fin tubing. Pins or other means for securing the tubular support means are inserted into the ends of the tubular support such that the support tube is affixed to the tube support assembly. The pins are secured to either the base pan or the structural assembly of the unit providing a tube support assembly as an integral part of the heat exchange unit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
A heat exchange unit having a base pan for supporting the unit, and a fan assembly and a subassembly which comprises: a heat exchanger formed from a plurality of runs of wound fin tubing: a support member having a vertically extending portion extending the height of the heat exchanger and having a top lateral portion and a bottom lateral portion both extending across the runs of wound fin tubing, each lateral portion defining an opening therein; a tubular support means extending through the openings in the lateral portions of the support member securing the runs of wound fin tubing between the tubular support means and the support member; and means for securing the tubular support means to the base pan and to the structural assembly for incorporating the subassembly as an integral part of the heat exchange unit.
Claim 2
Dependent Claim
138 words
A heat exchange unit having a base pan for supporting the unit, and a fan assembly and a subassembly which comprises: a heat exchanger formed from a plurality of runs of wound fin tubing: a support member having a vertically extending portion extending the height of the heat exchanger and having a top lateral portion and a bottom lateral portion both extending across the runs of wound fin tubing, each lateral portion defining an opening therein; a tubular support means extending through the openings in the lateral portions of the support member securing the runs of wound fin tubing between the tubular support means and the support member; and means for securing the tubular support means to the base pan and to the structural assembly for incorporating the subassembly as an integral part of the heat exchange unit.
Claim 3
Dependent Claim
43 words
The apparatus as set forth in claim 1 wherein the support member further comprises a run securing portion affixed to the vertically extending portion, said run securing portion defining notches adapted to each receive and secure a single run of wound fin tubing.
Claim 4
Dependent Claim
50 words
The apparatus as set forth in claim 1 wherein the support member further comprises an intermediate lateral portion having an opening therein for the receipt of the tubular support means, said intermediate lateral portion extending from the vertically extending portion between the top lateral portion and the bottom lateral portion.
Claim 5
Dependent Claim
61 words
The apparatus as set forth in claim 1 wherein the heat exchanger is formed by bending the wound fin tubing into a generally cylindrical configuration, wherein there are at least three subassemblies spaced about the heat exchanger each serving to secure the runs of the heat exchanger and each serving as a support between the base pan and the structural assembly.
Claim 6
Dependent Claim
41 words
The apparatus as set forth in claim 1 wherein the means for securing comprises at least one pin adapted to fit inside the tubular support means for securing the tubular support means to either the base pan or the structural assembly.
