Abstract
Abstract A heat exchanger, particularly a radiator for a motor vehicle, of the type comprising a plurality of fluid conduits and a plurality of spaced, parallel, plate-like fins extending transversely to the fluid conduits and attached thereto is provided with at least one mounting member, serving either to mount the heat exchanger on a supporting structure or to mount an accessory (such as a motor and fan unit) on the heat exchanger, or serving both those purposes, which mounting member extends adjacent the juxtaposed and edges of a plurality of the fins and has portions engaging each of the opposite side edges of the fins, so as to clamp the fins between them, at least one of the said portions of the mounting member including a claw which is engaged in aligned notches formed in the corresponding side edges of at least some of the fins.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
178 words
A heat exchanger comprising a plurality of fluid conduits extending between two headers, and a set of spaced parallel plate-like fins extending transversely to said fluid conduits and attached thereto to form a heat-exchanger core having a pair of opposite laminated peripheral faces formed by the respective end edges of the fins disposed adjacent one another, and a pair of opposite laminated athwart faces formed by the respective side edges of the fins disposed adjacent one another; and at least one mounting member extending along at least a region of one of said peripheral faces and having first and second flanges engaging respective regions of said athwart faces, said first flange including at least one claw engaged in aligned notches formed in the corresponding side edges of a plurality of said fins, and force fitted in said aligned notches towards said second flanges to grip therebetween that portion of the fins which is straddled by said claw and said second flange, whereby to hold the heatexchanger core ridigly fast to the supporting member through said plurality of fins.
Claim 2
Dependent Claim
178 words
A heat exchanger comprising a plurality of fluid conduits extending between two headers, and a set of spaced parallel plate-like fins extending transversely to said fluid conduits and attached thereto to form a heat-exchanger core having a pair of opposite laminated peripheral faces formed by the respective end edges of the fins disposed adjacent one another, and a pair of opposite laminated athwart faces formed by the respective side edges of the fins disposed adjacent one another; and at least one mounting member extending along at least a region of one of said peripheral faces and having first and second flanges engaging respective regions of said athwart faces, said first flange including at least one claw engaged in aligned notches formed in the corresponding side edges of a plurality of said fins, and force fitted in said aligned notches towards said second flanges to grip therebetween that portion of the fins which is straddled by said claw and said second flange, whereby to hold the heatexchanger core ridigly fast to the supporting member through said plurality of fins.
Claim 3
Dependent Claim
28 words
A heat exchanger as claimed in claim 1, wherein said claw comprises an edge portion of the first flange which is bent and pressed into said aligned notches.
Claim 4
Dependent Claim
43 words
A heat exchanger as claimed in claim 1, wherein said claw comprises an insert having a projection adapted to fit in said aligned notches, comprising screw means for drawing said insert towards the second flange to clamp said projection into saiD aligned notches.
Claim 5
Dependent Claim
40 words
A heat exchanger as claimed in claim 1, wherein the second flange includes at least one like claw engaged in aligned notches formed in the corresponding side edges of a plurality of fins, and force fitted towards the first flange.
Claim 6
Dependent Claim
38 words
A heat exchanger as claimed in claim 4, wherein the first flange comprises a plurality of spaced claws, and the second flange comprises a plurality of spaced claws offset longitudinally relative to the claws of the first flange.
Claim 7
Dependent Claim
28 words
A heat exchanger as claimed in claim 1, comprising means for fastening said mounting member to a support structure whereby to mount said heat-exchanger core on said structure.
Claim 8
Dependent Claim
27 words
A heat exchanger as claimed in claim 1, comprising means for fastening an accessory to the mounting member whereby to mount the accessory to the heat-exchanger core.
Claim 9
Dependent Claim
36 words
A heat exchanger as claimed in claim 3 in combination with an accessory, said second flange constituting part of said accessory, whereby operation of said screw means serves to secure said accessory to said heat exchanger.
Claim 10
Dependent Claim
37 words
The combination set forth in claim 8 further including means fast to said accessroy and embracing those end portions of a plurality of said fins that lie opposite to the end portions engaged by said mounting member.
Claim 11
Dependent Claim
63 words
The combination set forth in claim 8 wherein said accessory is a motor and fan unit comprising a hub to which the motor is secured, blades secured to the motor shaft, a circular casing encircling said blades, arms connecting said hub to said casing and lugs projecting from said casing and engaging said heat exchanger to secure said motor and fan unit thereto.
