  • contour elements can extend along the entire height h of the leg 82 from one fold 76 to an adjacent fold 76 (i.e., from a peak 78 to an adjacent valley 80 or vice versa).
  • Each contour element has a width d, as shown in FIG. 6 .
  • the width d also indicates the spacing between similar contour elements.
  • the spacing between similar contour elements can be greater than the width d of an intervening or alternating contour element.

  • an insert 66 formed with longitudinal rows of alternating contour elements 86 , 88 can be folded such that the space S between adjacent legs 82 at a particular height h can be generally constant along their length L.
  • the flow path cross-sectional area is essentially constant along the length L between opposite ends 68 of the tube 26 .
  • the first flow path 34 is made circuitous and is consequently longer than a straighter flow path.
  • Such an insert configuration can increase turbulence of the working fluid and consequently allow for more efficient heat transfer without causing significant pressure changes/buildup along the length L of the insert 66 .
  • contour elements formed in the inserts 66 can impact the shape of the spine 76 . For example, FIGS.
  • FIG. 3-8 show how a pattern of dimples 86 and protrusions 88 - specifically longitudinal rows of the continuously alternating contour elements—can create a serpentine-shaped spine 76 .
  • the serpentine shape of the spine 76 can also provide a reinforced connection between the tube 26 and the insert 66 which can also improve heat transfer.
  • the inserts 66 operate as elastic members to absorb or at least partially absorb vibrations and/or to absorb expansions and contractions of the inserts 66 caused by fluctuating temperatures of the first and/or second working fluids.
  • the elasticity of the contoured inserts 66 prevents or reduces cracking and breaking of the inserts 66 .
  • the elasticity of the contoured inserts 66 prevents and/or reduces cracking and breaking of connections (e.g., solder points, braze points, weld points, etc.) between the spines 76 of the inserts 66 and the interior sides of the tubes 26 .
  • contours 86 , 88 can extend continuously from a first lateral edge 92 to a second lateral edge 94 , along the length L of a leg 82 .
  • contours only extend continuously along the length L of a middle portion of the insert 66 , while the edges 92 , 94 have a different topographical configuration, such as, for example, wavy.
  • the contoured portion can allow for changes in length L (i.e., longitudinal flexibility), while the wavy edges can compensate for changes in height h of the legs 82 (i.e., vertical flexibility). This can be desirable in embodiments where the height of the insert H is constrained by connection to the inner surfaces of the tube 26 , especially where the tube ends 68 are further constrained by the first and second headers 18 , 20 .
  • FIG. 9 illustrates a method of forming an insert 66 for a heat exchanger 10 according to some embodiments of the present invention.
  • the method involves roll-forming a pattern of dimples 86 and protrusions 88 into a sheet of deformable heat conducting material 100 (e.g, aluminum, copper, bronze, and alloys including one or more of these metals).
  • deformable heat conducting material 100 e.g, aluminum, copper, bronze, and alloys including one or more of these metals.
  • the process of contour formation is shown in FIG. 9 (and discussed with reference to FIG. 9 ) as occurring in two distinct and consecutive steps for a particular longitudinally-located, lateral section of the sheet. First, at the right-hand side of the figure, dimples 86 are roll-formed, then, to the left of that, protrusions 88 are roll-formed.
  • roll-formation of dimples 86 and protrusions 88 can be executed simultaneously (as described and illustrated with respect to the alternative embodiments shown in FIGS. 10 and 11 below). Whether the dimples 86 and protrusions 88 are formed consecutively or simultaneously, the roll-formed insert 66 in FIG. 9 then undergoes a folding process (right-hand side of the figure) to create spines 76 . The steps discussed above can be incorporated into a high-speed assembly process which is described in more detail below.
  • the method can make use of a first cylindrically-shaped roller 102 having projections 104 positioned in longitudinal rows along its curved exterior surface 106 .
  • the first roller 102 can be rotated about its axis 108 as it makes contact with a first side 110 of the sheet of deformable material 100 , positioned tangentially with respect to the curved surface 106 .
  • the weight of the first roller 102 can be used to exert pressure on the deformable material such that the projections 104 form dimples 86 in the material 100 .
  • the sheet of material 100 can be forced into contact with the roller 100 by other means to form dimples 86 .
  • the shape and size of the projections 104 with respect to the thickness of the sheet of material 100 can be such that the dimples 86 formed by contact of projections 104 with the first side 110 of the sheet of deformable material 100 create their geometric complement on a second side (not visible) of the sheet 100 which is opposite to the first side 110 .
  • dimples 86 and protrusions 88 can be simultaneously formed on the first side 110 and an opposite second side of the sheet 100 , respectively.
  • a second cylindrically-shaped roller 112 having projections 114 positioned in longitudinal rows along its curved surface 116 can be positioned adjacent to the opposite side of the sheet 100 from the first roller 102 .

  • corresponding projections 88 can be formed on the first side 110 .
  • the rollers 102 , 112 can be formed by axially stacking cylindrical disks, the boundaries of which are illustrated by dashed lines in FIG. 9 .
  • disks with various shaped projections 114 and/or circumferential spacing between projections 114 can be assembled into a roller that will form inserts 66 with different dimensions and geographies.
  • the disks can be circumferentially staggered to provide inserts 66 with more or less space between rows of contour elements, which can result in wider or narrower spines 76 .
  • the rollers 102 , 112 can be arranged with respect to each other such that the dimples 86 and protrusions 88 on each side of the sheet are formed at specific locations with respect to each other. For example, FIGS.
  • rollers 102 , 112 can be aligned to form lateral and longitudinal rows of alternating dimples 86 and protrusions 88 along the sheet 100 .
  • the lateral rows are separated by narrow gaps where the sheet 100 can be folded to form corrugations such that the lateral rows become legs 82 and the gaps become spines 76 .
  • the rollers 102 , 112 are staggered slightly to form serpentine-shaped spines 76 .
  • the rollers 102 , 112 can be aligned to form straight spines 76 .
  • the positioning, size, and/or shape of the projections 104 , 114 on the first and/or second rollers 102 , 112 can be varied to change the geometry and/or topography of the insert 66 .

  • alternating ridges 122 and crevasses 124 create the star shape of the disk.
  • the ridges 122 and crevasses 124 can contribute to the formation of peaks 78 and valleys 80 as will be described in further detail below.
  • a projection 126 or an indention 128 is formed between each ridge 122 and crevasse 124 .
  • the projections 126 and indentions 128 can form dimples 86 and protrusions 88 in the insert as will also be discussed in further detail below.
  • the projections 126 and indentions 128 can be geometric complements and have multiple planes of symmetry as discussed previously with respect to dimples 86 and protrusions 88 .
  • the ridges 122 can be geometric complements of crevasses 124 .

  • the projections 136 can be geometric complements of indentions 128 and projections 126 can be geometric complements of indentions 138 , in which case, projections 126 , 136 need not be geometric complements of indentions 128 , 138 on the same disk.
  • the second star-shaped disk 130 is positioned on a second side 140 of the sheet of material 100 .
  • the first and second star-shaped disks 120 , 130 can be positioned with respect to each other such that each ridge 122 of the first disk 120 fits within a crevasse 134 of the second disk 130 and each ridge 132 of the second disk 130 fits within a crevasse 124 of the first disk 120 as the disks 120 , 130 turn on their respective axes.
  • the corresponding ridges 122 and crevasses 134 fold the material to form peaks 78
  • corresponding ridges 132 and crevasses 124 fold the material to form valleys 80 .
