Abstract
Abstract The invention belongs to the technical field of heat exchangers and relates, in particular, to an element for exchanging heat between two fluids of the same or of a different nature, and to a process for constructing the said heat exchange element. The element according to the invention comprises a flat tubular element 1 and fins 3, the latter placed at least on the major sides 2a of the the former, directed crosswise to the direction in which the said element extends. In the region of the extremities thereof, the said tubular element has parts 4 devoid of fins, the depth of which corresponds to the maximum height of the said fins 3.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
Element for exchanging heat between fluids, comprising a flat tubular element 1 in which a said first fluid is made to flow, and a plurality of fins 3 integral with the said tubular element, and characterized by the fact that the said fins 3 are placed on the major sides 2a of the said flat-tubular element, turned crosswise to the direot- ion in which the said element extends, over the full width of this, and that, in the region of the extremities thereof, the said tubular element has parts 4 devoid of fins, the depth of which corresponds to the maximum height of the said fins.
Claim 2
Dependent Claim
106 words
Element for exchanging heat between fluids, comprising a flat tubular element 1 in which a said first fluid is made to flow, and a plurality of fins 3 integral with the said tubular element, and characterized by the fact that the said fins 3 are placed on the major sides 2a of the said flat-tubular element, turned crosswise to the direot- ion in which the said element extends, over the full width of this, and that, in the region of the extremities thereof, the said tubular element has parts 4 devoid of fins, the depth of which corresponds to the maximum height of the said fins.
Claim 3
Dependent Claim
42 words
Exchange element according to Claim 1, characterized by the fact that the minor sides 2b of the said tubular element are provided with diametrically opposed wedge shaped projections 6 designed to serve as lips for a flow of a said second fluid.
Claim 4
Dependent Claim
24 words
Exchange element according to Claim 1, characterized by the fact that the said fins 3 t extend crosswise in an undulated or sinusoidal arrangement.
Claim 5
Dependent Claim
38 words
Radiator characterized by the fact of comprising a plurality of exchange elements 1 formed in accordance with one or more of the preceding claims and arranged stacked in a direction perpendicular to the main finned sides 2a thereof.
Claim 6
Dependent Claim
30 words
Radiator according to Claim 3, characterized by the fact that the said exchange elements 1 are joined one to the other in the region of the said finless parts 4.
Claim 7
Dependent Claim
23 words
Radiator according to Claim 5, characterized by the fact that the said finless parts 4 are externally connected to outside end manifolds 12.
Claim 8
Dependent Claim
22 words
Radiator according to Claim 4, characterized by the fact that a metal material partition is placed between two superposed exchange elements 1.
Claim 9
Dependent Claim
90 words
Process for constructing a heat exchanger defined by a finned tubular element, characterized by the fact of consisting in : forming a flat, thick wall, tubular element 1 that is cut into lengths corresponding to the size it is wished the heat exchangers to be, and fashioning, in the region of the main sides 2a of the said flat tubular element, fins 3 with the use of tools 7 having multiple cutting edges 8 parallel one with the other and movable in a direction crosswise to the maximum dimension thereof.
Claim 10
Dependent Claim
90 words
Process for constructing a heat exchanger defined by a finned tubular element, characterized by the fact of consisting in : forming a flat, thick wall, tubular element 1 that is cut into lengths corresponding to the size it is wished the heat exchangers to be, and fashioning, in the region of the main sides 2a of the said flat tubular element, fins 3 with the use of tools 7 having multiple cutting edges 8 parallel one with the other and movable in a direction crosswise to the maximum dimension thereof.
Claim 11
Dependent Claim
34 words
Process according to Claim 6, characterized by the fact that the said tubular element is cut in the region of the central part thereof, over the full width except for the extreme parts thereof.
Claim 12
Dependent Claim
54 words
Process according to Claim 8, characterized by the fact that after the crosswise cutting phase, a further phase is envisaged for discontinuously altering the shape of the peripheral part of the fins 3 1 through the penetration, at a number of points, of a jig M provided with a plurality of deforming projections D.
