Abstract
Abstract The housing of the heat exchanger has an elongated body section. Located within the body section are two axially-spaced radiallydisposed header plates with a plurality of axial apertures. Extending through the apertures are a plurality of elongated tubes. The body section and the header plates are compressed radially inwardly to effect a tight engagement between the body section and the header plates and between the header plates and the tubes. Brazing material seals the header plates to the body section and seals the tubes to the header plates.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
90 words
A heat exchanger assembly, comprising; a generally tubular housing, a flat header plate adjacent each end of the housing having an original exterior dimension less than the original interior dimension on said housing, a plurality of heat exchange tubes supported in said header plates, said housing having a peripherally compressed portion radially of at least one of said header plates for firmly holding said one header plate in position, said one header plate having a peripherally compressed portion firmly engaged with said peripherally compressed portion of the one header plate.
Claim 2
Dependent Claim
90 words
A heat exchanger assembly, comprising; a generally tubular housing, a flat header plate adjacent each end of the housing having an original exterior dimension less than the original interior dimension on said housing, a plurality of heat exchange tubes supported in said header plates, said housing having a peripherally compressed portion radially of at least one of said header plates for firmly holding said one header plate in position, said one header plate having a peripherally compressed portion firmly engaged with said peripherally compressed portion of the one header plate.
Claim 3
Dependent Claim
83 words
A heat exchanger assembly, comprising; a tUbular housing having an original exterior dimension less than the original interior dimension on said housing, a flat header plate adjacent each end of the housing, said header plates being fixed within said housing, said header plates having a plurality of aligned apertures therein, a plurality of heat exchange tubes in said aligned apertures, said apertures having radially inward peripherally deformed portions in firm engagement with said tubes to hold the tubes securely in the header plates.
Claim 4
Dependent Claim
83 words
A heat exchanger assembly, comprising; a tUbular housing having an original exterior dimension less than the original interior dimension on said housing, a flat header plate adjacent each end of the housing, said header plates being fixed within said housing, said header plates having a plurality of aligned apertures therein, a plurality of heat exchange tubes in said aligned apertures, said apertures having radially inward peripherally deformed portions in firm engagement with said tubes to hold the tubes securely in the header plates.
