Abstract
Abstract Corrugated dissipator for tube and dissipator radiator cores wherein said dissipator has continuous areas for support on adjacent tubes, folded straps connecting the continuous areas being alternately bent to be successively imbricated by each other. Process for manufacturing corrugated dissipator for tube and dissipator core wherein parallel sets of slots are made lengthwise in a thin strip and delimit straps which are alternatively and oppositely fold. The strips are corrugated at the level of continuous areas separating each set of straps and are advancing while being retained in the corrugated portion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
A grille for a heat exchanger having spaced parallel tubes for conveying a fluid heat transfer medium comprising an elongate member of heat conducting material having a generally zig-zag confIguration to be disposed between two parallel tubes of an exchanger and including alternate angular and intermediate portions therebetween, the angular portions at the opposite sides of said grille constituting supporting areas for engagement with the respective tubes, and the intermediate portions having longitudinally extending slits dividing said portions into a plurality of side by side longitudinally extending straps which alternatively extend in opposite directions relative to the plans of said portions, the straps of adjacent intermediate portions being interleaved.
Claim 2
