Abstract
Abstract The spaced apart elongated supporting members for the various tubular coils of a heat exchanger include vertically spaced apart openings in a wall portion thereof which faces an associated supporting member, the tubular coil being fitted to extend through the openings and thus be supported by the supporting members. A pair of such members, together with the supported tubular coil, comprise a heat exchange section, the entire heat exchanger including a multiplicity of such sections. Each individual section can be separately disconnected and removed from the heat exchanger if a leak develops in the supported tubular coil in a fast and efficient manner.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
171 words
A component heat exchanger which can be easily disassembled and reassembled to replace defective portions thereof, said heat exchanger comprising a multiplicity of individual sections positioned in side-by-side relationship, each individual section including two spaced apart elongated supporting members and a tubular coil supported therebetween, the side-by-side positioned individual sections thus forming two spaced apart sets of side-by-side positioned elongated supporting members, each said elongated supporting member including a wall facing the corresponding supporting member of the individual section, said facing wall of each supporting member including spaced apart openings positioned in the longitudinal direction thereof, said tubular coil comprising a multiplicity of vertical spaced apart horizontal segments and interconnecting bent segments, said horizontal segments being positioned to extend through said openings in said facing walls of said supporting members so as to be supported by said supporting members, and wherein said individual sections are fixedly positioned in side-by-side relationship by separate clamping means which separately clamp together the elongated supporting members which form said two sets of elongated supporting members.
Claim 2
Dependent Claim
171 words
A component heat exchanger which can be easily disassembled and reassembled to replace defective portions thereof, said heat exchanger comprising a multiplicity of individual sections positioned in side-by-side relationship, each individual section including two spaced apart elongated supporting members and a tubular coil supported therebetween, the side-by-side positioned individual sections thus forming two spaced apart sets of side-by-side positioned elongated supporting members, each said elongated supporting member including a wall facing the corresponding supporting member of the individual section, said facing wall of each supporting member including spaced apart openings positioned in the longitudinal direction thereof, said tubular coil comprising a multiplicity of vertical spaced apart horizontal segments and interconnecting bent segments, said horizontal segments being positioned to extend through said openings in said facing walls of said supporting members so as to be supported by said supporting members, and wherein said individual sections are fixedly positioned in side-by-side relationship by separate clamping means which separately clamp together the elongated supporting members which form said two sets of elongated supporting members.

Claim 8
Dependent Claim
29 words
The heat exchanger of claim 1 wherein each of said clamping means comprises a frame which encases the ends of all the elongated supporting members which it clamps together.
Claim 9
Dependent Claim
28 words
The heat exchanger of claim 1 wherein each tubular coil of each individual section includes connecting tubes attached to the ends thereof for connection with separate collector vessels.
Claim 10
Dependent Claim
29 words
The heat exchanger of claim 1 wherein each tubular coil of each individual section is connected in series with at least one tubular coil of an adjacent individual section.
Claim 11
Dependent Claim
26 words
The heat exchanger of claim 1 wherein the openings in the facing wall of at least one supporting member of each individual section are slot shaped.
Claim 12
Dependent Claim
26 words
The heat exchanger of claim 1 wherein the openings in the facing wall of one supporting member of each individual section are shaped as circular holes.
Claim 13
Dependent Claim
79 words
The heat exchanger of claim 1 wherein each said supporting member comprises an elongated bar having a block C-shaped horizontal cross section as seen from the other supporting member of the respective individual section so as to have a center wall and two spaced apart extension walls with free edges, and wherein said openings in the facing walls are located within either one of the extension walls and adjacent a free edge so as to have an unenclosed portion.
Claim 14
Dependent Claim
70 words
The heat exchanger of claim 1 wherein each said supporting member comprises an elongated bar having an L-shaped horizontal cross section as seen from the other supporting member of the respective individual section, with each of the two connected walls having free edges, and wherein said openings in the facing walls are located adjacent a free edge of either one of said walls so as to have an unenclosed portion.
Claim 15
Dependent Claim
135 words
The heat exchanger of claim 1 wherein the openings in the facing wall of a first supporting member of each individual section are slot shaped, wherein the openings in the facing wall of the second supporting member of each individual section are in the form of circular holes, wherein two adjacent spaced apart horizontal segments of the tubular coil have and non-interconnected ends which fit within separate circular holes in said second supporting member so as to be supported by said second supporting member, and wherein the opposite and interconnected ends of said two adjacent spaced apart horizontal segments of the tubular coil fit within a single slot in said first supporting member, such that the horizontal segments of said tubular coil can be slidingly removed from within the slots of said first supporting member.
Claim 16
Dependent Claim
171 words
A heat exchanger which can be easily disassembled and reassembled to replace defective parts, said heat exchanger comprising a multiplicity of individual sections positioned in side-by-side relationship, each individual section including two spaced apart elongated supporting members and a tubular coil supported therebetween, the side-by-side positioned individual sections thus forming two spaced apart sets of side-by-side positioned elongated supporting members, each said elongated supporting member including a wall facing the corresponding supporting members of the individual section, said facing wall of each supporting member including spaced apart openings positioned in the longitudinal direction thereof, said tubular coil comprising a multiplicity of vertical spaced apart horizontal segments and interconnecting bent segments, said horizontal segments being positioned to extend through said openings in said facing walls of said supporting members so as to be supported by said supporting members, each said elongated supporting member also including a wall opposite said facing wall which is flat, such that the two sets of side-by-side positioned elongated members define smooth outer walls for the heat exchanger.
