Abstract

Abstract An absorption-cooling unit which comprises a collector and a plurality of conduits originating from the collector and at least partly boxed into each other. A collector housing includes at least two cap parts welded together in a cross-plane and having bottom faces. The conduits start from the bottom faces of the collector housing.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 285 words
An assembly for an absorption-cooling unit comprising a collector having a collector housing having a longitudinal axis and including two cap parts welded together in a crossplane to said axis and each having a bottom face on opposite sides of said housing, a plurality of conduits originating from said collector and at least partly boxed into each other, said conduits starting from both of said bottom faces of said cap parts of said collector housing in coaxial alignment, one of said conduits comprising a gas-heat exchanger outermost tube originating from said bottom face of one of said cap parts, another of said conduits comprising an outer tube starting from the bottom face of said other of said cap parts and extending through said collector housing and entering in coaxially opposite position thereto and constituting thereat a gas-heat exchanger inner tube disposed coaxially inside said gas-heat exchanger outermost tube, sAid outer tube from said other cap part extends over a liquid heat exchanger path, a boiler path, a rectification path, a boiler rising tube path and a dephlegmator path to a liquefier, an inner tube terminating separately into said collector, said inner tube extending coaxially inside said outer tube away from said collector and said other cap part thereof up to said boiler rising tube path, a following pump tube extending inside of and welded to one end of said inner tube remote from said collector and adjacent said boiler rising tube path, in order to bend said unit, only after boxing into each other of said conduits and providing of all tube-welding seams on the conduits, from its straight lined arrangement coaxial to said longitudinal axis of said collector housing, into a predetermined curved state.
Claim 2
Dependent Claim 285 words
An assembly for an absorption-cooling unit comprising a collector having a collector housing having a longitudinal axis and including two cap parts welded together in a crossplane to said axis and each having a bottom face on opposite sides of said housing, a plurality of conduits originating from said collector and at least partly boxed into each other, said conduits starting from both of said bottom faces of said cap parts of said collector housing in coaxial alignment, one of said conduits comprising a gas-heat exchanger outermost tube originating from said bottom face of one of said cap parts, another of said conduits comprising an outer tube starting from the bottom face of said other of said cap parts and extending through said collector housing and entering in coaxially opposite position thereto and constituting thereat a gas-heat exchanger inner tube disposed coaxially inside said gas-heat exchanger outermost tube, sAid outer tube from said other cap part extends over a liquid heat exchanger path, a boiler path, a rectification path, a boiler rising tube path and a dephlegmator path to a liquefier, an inner tube terminating separately into said collector, said inner tube extending coaxially inside said outer tube away from said collector and said other cap part thereof up to said boiler rising tube path, a following pump tube extending inside of and welded to one end of said inner tube remote from said collector and adjacent said boiler rising tube path, in order to bend said unit, only after boxing into each other of said conduits and providing of all tube-welding seams on the conduits, from its straight lined arrangement coaxial to said longitudinal axis of said collector housing, into a predetermined curved state.
Claim 3
Dependent Claim 54 words
The assembly, as set forth in claim 1, which includes an absorption coil emerging in the vicinity of said bottom face of said one of said cap parts cross-wise from said cap wall, and enters with its opposite end into said outer tube, the latter passing through said bottom of said one cap part.
Claim 4
Dependent Claim 23 words
The assembly, as set forth in claim 1, which includes a displacement tube provided in said liquefier for increase of the steam speed.
Claim 5
Independent Claim 238 words
A method of constructing an assembly for an absorption cooling device, comprising the steps of coaxially joining an inner tube at one end thereof to a pump tube, the latter being positioned coaxially inside the former, coaxially inserting said inner tube inside an outer tube, welding an upper radially turned end of said inner tube to a bore portion of said outer tube, connecting a first cap part of a collector having a bottom opening about said outer tube at a position such that said radially turned end of said inner tube terminates inside said cap, passing an other cap part of said collector having a bottom opening about said outer tube such that the latter extends through said collector and through the bottom opening of said other cap part, welding the two cap parts in a cross plane, cross to the longitudinal axis of the said collector, said outer tube extending coaxially to said longitudinal axis, coaxially positioning a heat exchanger outermost tube about a portion of said outer tube which extends away from said collector away from said bottom opening of said other cap part, welding said heat exchanger outer tube about the bottom opening of said other cap part to said other cap part, the welding steps comprising the step of turning of said collector about the coaxial axis of said collector of said tubes, and thereafter bending said welded tubes connected with said collector.
Claim 6
Independent Claim 238 words
A method of constructing an assembly for an absorption cooling device, comprising the steps of coaxially joining an inner tube at one end thereof to a pump tube, the latter being positioned coaxially inside the former, coaxially inserting said inner tube inside an outer tube, welding an upper radially turned end of said inner tube to a bore portion of said outer tube, connecting a first cap part of a collector having a bottom opening about said outer tube at a position such that said radially turned end of said inner tube terminates inside said cap, passing an other cap part of said collector having a bottom opening about said outer tube such that the latter extends through said collector and through the bottom opening of said other cap part, welding the two cap parts in a cross plane, cross to the longitudinal axis of the said collector, said outer tube extending coaxially to said longitudinal axis, coaxially positioning a heat exchanger outermost tube about a portion of said outer tube which extends away from said collector away from said bottom opening of said other cap part, welding said heat exchanger outer tube about the bottom opening of said other cap part to said other cap part, the welding steps comprising the step of turning of said collector about the coaxial axis of said collector of said tubes, and thereafter bending said welded tubes connected with said collector.
