Abstract
Abstract A heat exchange assembly is disclosed, which assembly when placed, for example, in a temperature controlled environment, allows heat exchange between the environment and a fluid passed through the assembly. The heat exchange assembly comprises a plurality of elongated headers each having closed ends and longitudinally arranged inlet holes and outlet holes to provide fluid passage through the header from the inlet holes to the outlet holes transversely to the longitudinal. The headers are interconnected by tubes so that the fluid will pass sequentially through successive headers. Each header may advantageously be provided with a removable plate to allow insertion of cleaning reamers into the inside of the tubes. The heat exchange assembly is adapted to be constructed from readily available materials to form a self-supporting unitary structure.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
295 words
A heat exchange assembly to allow heat exchange with a fluid to pass through said assembly comprising: (a) a plurality of headers sequentially numbered from a first header to a last header, each header being elongated, having sealed ends, and comprising two pipes of circular cross-section sealably and fixedly connected along their lengths to each other at a single line of contact, each having an interior and a pipe wall, a longitudinal array of inlet holes passing through said pipe wall of one of said two pipes and a longitudinal array of outlet holes passing through said pipe wall of said other of said two pipes, with each pipe wall further having an elongate aperture therethrough running throughout the entire length of the pipe; and at least one plate member sealably affixed to both said pipes so that an inner chamber is defined by said sealed ends, said pipe walls, and said at least one plate member whereby fluid communication is provided through said chamber traverse to the longitudinal from said inlet holes to said outlet holes through said interior and said elongate aperture of both pipes, (b) a plurality of tubes consisting of connecting tubes, entrance tubes and departure tubes, wherein one end of an entrance tube is received in each of the inlet holes of the first header, one end of a departure tube is received in each of the outlet holes of the last header, and each outlet hole of each header other than the last header receives one end of a connecting tube the other end of which is received in an inlet hole of the next higher sequentially numbered header, whereby said fluid may pass from said entrance tubes through said headers in increasing numerical succession to the departure tubes.
Claim 2
Dependent Claim
295 words
A heat exchange assembly to allow heat exchange with a fluid to pass through said assembly comprising: (a) a plurality of headers sequentially numbered from a first header to a last header, each header being elongated, having sealed ends, and comprising two pipes of circular cross-section sealably and fixedly connected along their lengths to each other at a single line of contact, each having an interior and a pipe wall, a longitudinal array of inlet holes passing through said pipe wall of one of said two pipes and a longitudinal array of outlet holes passing through said pipe wall of said other of said two pipes, with each pipe wall further having an elongate aperture therethrough running throughout the entire length of the pipe; and at least one plate member sealably affixed to both said pipes so that an inner chamber is defined by said sealed ends, said pipe walls, and said at least one plate member whereby fluid communication is provided through said chamber traverse to the longitudinal from said inlet holes to said outlet holes through said interior and said elongate aperture of both pipes, (b) a plurality of tubes consisting of connecting tubes, entrance tubes and departure tubes, wherein one end of an entrance tube is received in each of the inlet holes of the first header, one end of a departure tube is received in each of the outlet holes of the last header, and each outlet hole of each header other than the last header receives one end of a connecting tube the other end of which is received in an inlet hole of the next higher sequentially numbered header, whereby said fluid may pass from said entrance tubes through said headers in increasing numerical succession to the departure tubes.
Claim 3
Dependent Claim
45 words
A heat exchange assembly as claimed in claim 1 wherein each odd numbered header is fixedly joined along its length to the next sequentially numbered odd header and each even numbered header is fixedly joined along its length to the next sequentially numbered even header.
Claim 4
Dependent Claim
15 words
The heat exchange assembly of claim 1 wherein said connecting tubes are straight connecting tubes.
Claim 5
Dependent Claim
18 words
The heat exchange assembly as claimed in claim 3 wherein said at least one plate member is removable.
Claim 6
Dependent Claim
61 words
The heat exchange assembly as claimed in claim 1 wherein said longitudinal elongate aperture, each said inlet hole of one of said two pipes and the tubes received therein are arranged to permit co-linear extension of a straight cleaning means through the longitudinal elongate aperture and the inlet hole into the tube when the at least one plate member is removed.
Claim 7
Dependent Claim
63 words
A heat exchange assembly as claimed in claim 5 wherein said longitudinal elongate aperture, each said outlet hole of the other of said two pipes and the connecting tube received therein are arranged to permit co-linear extension of a straight cleaning means through the longitudinal elongate aperture and the outlet hole into the tube when the at least one plate member is removed.
Claim 8
Dependent Claim
144 words
A header for a heat exchange assembly comprising two elongate pipes of circular cross-section sealably and fixedly connected along their lengths to each other at a single line of contact, each pipe having an interior and a pipe wall, each pipe having a longitudinal array of holes passing through its pipe wall, each pipe further having an elongate aperture through its pipe wall extending throughout the length of the pipe an elongate, planar plate member sealably affixed to both said pipes so that an inner chamber is defined by said pipe walls and said plate member whereby fluid communication is provided through the chamber transverse to the longitudinal from the holes of one pipe to the holes of the other pipe in succession through the interior and elongate aperture of said one pipe and through the elongate aperture and interior of said other pipe.
Claim 9
Dependent Claim
144 words
A header for a heat exchange assembly comprising two elongate pipes of circular cross-section sealably and fixedly connected along their lengths to each other at a single line of contact, each pipe having an interior and a pipe wall, each pipe having a longitudinal array of holes passing through its pipe wall, each pipe further having an elongate aperture through its pipe wall extending throughout the length of the pipe an elongate, planar plate member sealably affixed to both said pipes so that an inner chamber is defined by said pipe walls and said plate member whereby fluid communication is provided through the chamber transverse to the longitudinal from the holes of one pipe to the holes of the other pipe in succession through the interior and elongate aperture of said one pipe and through the elongate aperture and interior of said other pipe.
