Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
In a heat exchanger assembly comprising a plurality of heat exchange fluid conducting fins and conduits, end plates for spacing said conduits, and vertical lateral channel plates having flanges facing outwardly for laterally holding said conduits, the improvement comprising: means for tying said lateral channel plates together, said tying means comprising a plurality of shackle elements and plurality of cooperative apertures in the flange of said lateral channel plates, each said shackle element being in cooperative engagement with said flange and disposed therewithin, and with a said cooperative aperture, each said shackle element comprising an aperture engaging portion of strip material folded back to define a generally Ushaped retaining clip, the ends of said ''''U'''' being spaced apart a distance greater than the width of said aperture.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
24 words
A heat exchanger in accordance with claim 1, wherein said tying means comprises an elongated strap having said shackle element at each end thereof.
Claim 4
Dependent Claim
21 words
A heat exchanger in accordance with claim 1, wherein said shackle elements are disposed on opposite ends of said end plates.
Claim 5
Dependent Claim
33 words
