Abstract
Abstract A heat exchanger assembly has an elongated shell provided with fluid inlet and fluid outlet openings. An elongated bundle assembly is received within the shell. The bundle assembly has a plurality of elongated tubes extending generally longitudinally and a plurality of generally parallel fin plates which are transversely oriented. The bundle assembly has a top sheet and a bottom sheet. The bundle assembly support is interposed between the bottom sheet and the shell. A baffle is provided in the form of an elongated plate extending generally diagonally between the top sheet of the bundle assembly and the shell. In a preferred form, the baffle plate is provided with an underlying seal which is interposed between the baffle plate and the top sheet and has an upper edge which is of generally complementary curvature with respect to the adjacent portions of the shell and may take the form of a portion of a sine wave. The bundle assembly support may provide cooperation to facilitate insertion of the bundle assembly into the shell and removal of the same therefrom. The bundle assembly support may cooperate with the shell in defining a condensate receipt reservoir.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
143 words
A heat exchanger assembly comprising an elongated shell having a fluid inlet and a fluid outlet, an elongated bundle assembly received within said shell, said bundle assembly having a plurality of elongated tubes extending generally longitudinally within said bundle assembly and a plurality of generally parallel fin plates oriented generally transversely with respect to said elongated tubes, said bundle assembly having a top sheet and a bottom sheet, bundle assembly support means interposed between said bottom sheet and said elongated shell, baffle means interposed between said top sheet and said elongated shell, said baffle means separating said fluid inlet and said fluid outlet, and said baffle means including an elongated baffle plate extending longitudinally generally diagonally on said bundle assembly between said fluid inlet and said fluid outlet, whereby said baffle plate directs said fluid through the full longitudinal extent of said bundle.
Claim 2
Dependent Claim
143 words
A heat exchanger assembly comprising an elongated shell having a fluid inlet and a fluid outlet, an elongated bundle assembly received within said shell, said bundle assembly having a plurality of elongated tubes extending generally longitudinally within said bundle assembly and a plurality of generally parallel fin plates oriented generally transversely with respect to said elongated tubes, said bundle assembly having a top sheet and a bottom sheet, bundle assembly support means interposed between said bottom sheet and said elongated shell, baffle means interposed between said top sheet and said elongated shell, said baffle means separating said fluid inlet and said fluid outlet, and said baffle means including an elongated baffle plate extending longitudinally generally diagonally on said bundle assembly between said fluid inlet and said fluid outlet, whereby said baffle plate directs said fluid through the full longitudinal extent of said bundle.
Claim 3
Dependent Claim
36 words
The heat exchanger assembly of claim 1 including said baffle plate having a lower edge disposed adjacent to said bundle means top sheet, and first seal means interposed between said lower edge and said top sheet.
Claim 4
Dependent Claim
50 words
The heat exchanger assembly of claim 2 including said first seal means having a generally flat base portion in contact with said top sheet, said first seal means having a generally upwardly open channel, and said lower edge of said baffle plate being disposed within said first seal means channel.
Claim 5
Dependent Claim
19 words
The heat exchanger assembly of claim 3 including said first seal means being substantially co-extensive with said baffle plate.
Claim 6
Dependent Claim
71 words
The heat exchanger assembly of claim 2 including said elongated shell being generally cylindrical and having a front closure and a rear closure, and said baffle plate having an upper edge of generally complementary shape with respect to the adjacent overlying portion of said shell, whereby passage of fluid entering said fluid inlet to said fluid outlet by flow between said baffle plate upper edge and said shell will be resisted.
Claim 7
Dependent Claim
17 words
The heat exchanger assembly of claim 5 including said baffle plate upper edge being generally upwardly convex.
Claim 8
Dependent Claim
25 words
The heat exchanger assembly of claim 6 including said baffle plate upper edge having a configuration which is generally a portion of a sine wave.
Claim 9
Dependent Claim
14 words
The heat exchanger assembly of claim 6 including said baffle plate being substantially planar.
Claim 10
Dependent Claim
32 words
The heat exchanger assembly of claim 1 including said bundle assembly top sheet being substantially rectangular, and said baffle plate extending generally from one corner thereof to a diagonally opposed corner thereof.
Claim 11
Dependent Claim
20 words
The heat exchanger assembly of claim 1 including said bundle assembly having a transverse cross-sectional configuration which is substantially rectangular.
Claim 12
Dependent Claim
35 words
The heat exchanger assembly of claim 10 including a front cover plate secured to the front end of said bundle assembly, and said front cover plate being of greater cross-sectional area than said bundle assembly.
Claim 13
Dependent Claim
32 words
The heat exchanger assembly of claim 1 wherein said bundle support means includes an elongated downwardly open channel member having an upper plate portion and depending leg portions secured to said shell.
Claim 14
Dependent Claim
27 words
The heat exchanger assembly of claim 12 wherein bundle seal means are interposed between said bottom sheet and said channel upper plate portion for effecting sealing therebetween.
Claim 15
Dependent Claim
77 words
The heat exchanger assembly of claim 13 including said bundle seal means having a seal plate member secured to said bottom sheet and projecting downwardly therefrom and second seal means, and said second seal means having a generally flat surface in contact with said channel upper plate portion and an upwardly open channel within which said seal plate member is received, whereby passage of fluid between said bundle assembly and said bundle assembly support means is resisted.
Claim 16
Dependent Claim
41 words
The heat exchanger assembly of claim 13 including said bundle assembly means having transport means cooperating with said downwardly open channel member to facilitate insertion of said bundle assembly within said shell and removal of said bundle assembly from said shell.
Claim 17
Dependent Claim
47 words
The heat exchanger assembly of claim 15 wherein said transport means includes at least one pair of guide members depending from said bottom sheet and supporting rollers in contact with said channel member, whereby relative rolling movement between said bundle assembly and said shell may be effected.
