Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
A manifold for a heat exchanger assembly comprising a first elongate hollow conduit and a second elongate hollow conduit extending side-by-side adjacent one another, said conduits being formed from a single elongate sheet metal strip, each conduit having a first portion extending throughout its length and having a plurality of integral tubular portions drawn from the sheet metal of said first portion and extending generally perpendicular to said first portion, the tubular portions of each conduit being spaced at intervals along the length of the conduit, each of said tubular portions being in communication with the interior of the respective conduit, each conduit further having second and third portions of the strip bent to extend back from said first portion at the sides thereof and further integral portions of the strip bent to complete the hollow form of the conduit, and means closing the ends of the conduit.
Claim 2
Dependent Claim
148 words
A manifold for a heat exchanger assembly comprising a first elongate hollow conduit and a second elongate hollow conduit extending side-by-side adjacent one another, said conduits being formed from a single elongate sheet metal strip, each conduit having a first portion extending throughout its length and having a plurality of integral tubular portions drawn from the sheet metal of said first portion and extending generally perpendicular to said first portion, the tubular portions of each conduit being spaced at intervals along the length of the conduit, each of said tubular portions being in communication with the interior of the respective conduit, each conduit further having second and third portions of the strip bent to extend back from said first portion at the sides thereof and further integral portions of the strip bent to complete the hollow form of the conduit, and means closing the ends of the conduit.
Claim 3
Dependent Claim
