Definitions

  • the invention relates to heat exchangers, and in particular, to plate and fin type heat exchangers of the type commonly used in vehicles.
  • FR 2 809 482 discloses such a heat exchanger according to the preamble of claim 1.
  • engine coolant heat exchangers such as radiators
  • radiators have been made by providing a plurality of parallel, spaced-apart flat tubes with cooling fins located therebetween to form a core. Opposed ends of the tubes pass through openings formed in manifolds or headers located on each side of the core at the respective ends of the tubes.
  • a difficulty with this type of construction is that the tube to header joints are difficult to fabricate and prone to leakage.
  • the tube to header joints to fail as a result of stresses caused by thermal cycling. Therefore, this type of construction presents problems with both the manufacture and operation of the heat exchanger.
  • U.S. Patent No. 6,332,495 which issued to Jamison et al. discloses a clip-on manifold heat exchanger formed from a plurality of stacked plate pairs having raised peripheral edge portions to define flow channels inside the plate pairs.
  • the plates of the plate pairs are formed with offset, diverging end flanges that space the plate pairs apart.
  • a U-shaped channel envelopes the plate end flanges to form part of a manifold at each end of the plate pairs, and end caps or plates close the open ends of the U-shaped channels to complete the manifolds.
  • the components are typically joined together by brazing or any other suitable technique.
  • U.S. Patent No. 6,513,585 which issued to Brost et al. discloses a headerless vehicle radiator formed of tubes having end walls which are bifurcated for a short distance from the ends of the tubes and having one or both of the sidewalls in the bifurcated segment of the tube formed outwardly and adapted to contact and be joined in a fluid tight manner with the sidewall of an adjacent tube in the radiator core.
  • a collecting tank (or manifold) has walls extending partially over the radiator core to a distance beyond the bifurcation of the sidewalls, the collecting tank walls being joined to the end walls of the tubes in a fluid tight manner.
  • the performance of the heat exchanger depends in part on the effectiveness of the joint achieved between the plate pairs and the walls of the U-shaped channels or manifolds. Due to the thicknesses of the materials used in creating the components of these types of heat exchangers, it can be difficult to achieve an effective seal or bond between the plate pairs.
  • French Patent Application Publication FR 2 809 482 A1 describes a tube matrix for a motor vehicle heat exchanger which has alternating first and second plates. Each first plate has parallel folded edges to rest on a respective second plate and each second plate has two parallel folded edges to rest on a respective first plate. Turbulence generators and spacers are alternatingly positioned between each first and second plate to define crossing channels for the two fluids.
  • the plates in the plate pairs are oriented at 90 degrees to one another, so that end portions of the plate sidewalls provide more surface area to better seal with the manifold walls.
  • heat exchanger 10 is in the form of a radiator for cooling the coolant of an internal combustion engine, such as is typically found in an automotive vehicle.
  • heat exchanger of the present invention can be used for various applications such as oil coolers or charge-air applications which operate using various types of fluids.
  • Heat exchanger 10 includes a core 12 formed of a plurality of stacked, alternating first and second heat exchange plates 14, 16 with cooling fins 18 located therebetween.
  • Cooling fins 18 are the usual type of corrugated cooling fins having transverse undulations or louvres formed therein to increase heat transfer. However, any type of cooling fin could be used in the present invention or even no cooling fin at all, if desired.
  • Heat exchanger 10 has a pair of manifold members 20, 22 located at the respective ends of the heat exchanger core 12.
  • Inlet and outlet nipples or fittings 24, 26 are mounted in one of the manifold members 20, 22 for the flow of coolant into and out of the heat exchanger 10. While the inlet and outlet fittings 24, 26 are shown in Figure 1 as being mounted in the same manifold member with a baffle member 27 therebetween, it will be understood that the inlet and outlet fittings 24, 26 can be mounted in separate manifold members, without the use of a baffle, depending on the specific configuration of the heat exchanger 10.
  • a top end plate 28 closes the upper ends of manifold members 20, 22 and provides a location for a filler cap fitting 30 and filler cap 32, as well as a mounting bracket 34 used for mounting the heat exchanger 10 in a desired location.
  • the filler cap fitting 30 also includes an overflow or pressure relief outlet 33.
  • a bottom end plate 36 is also provided for closing the lower ends of manifold members 20, 22. Bottom end plate 36 also provides a location for the attachment of another mounting bracket 38 for mounting heat exchanger 10 in the desired location. It will be understood that although the filler cap fitting 30 and filler cap 32 have been shown as being mounted in the top end plate 28, these components could in fact be mounted in or attached to either manifold member 20, 22 as opposed to the top end plate 28.
  • FIG. 2 illustrates a heat exchanger core 12 according to the prior art.
  • heat exchanger core 12 is formed from a plurality of stacked, alternating first and second heat exchange plates 14, 16.
  • the first heat exchange plates 14 are formed of inverted, generally U-shaped channel members each having a top wall 40, two downwardly depending closed peripheral side walls 42, and open ends 44.
  • the closed peripheral side walls 42 also include inwardly bent flange portions 50 for resting on the adjacent second heat exchange plate 16 when the first and second plates 14, 16 are alternatingly stacked together.
  • first heat exchange plates 14 have end portions 46 (see Figure 2A ) which include the end edges 47 of a portion of the top wall 40, the end edges 48 of the closed peripheral side walls 42, and the end edges 49 of inwardly bent flange portion 50.
  • the second heat exchange plates 16 are also formed of inverted, generally U-shaped channel members each having a top wall 52, two downwardly depending closed peripheral sidewalls 54, and open ends 56.
  • the closed peripheral side walls 54 also include inwardly bent flange portions 64 for resting on the adjacent first heat exchange plate 14 when the first and second plates 14, 16 are stacked together in their alternating relationship.
  • the second heat exchange plates 16 have end portions 58 (see Figure 2B ) which include planar regions 60 of the side walls 54 adjacent the end edges 62 thereof.
  • the heat exchanger core 12 is assembled so that as the first and second heat exchange plates 14, 16 are stacked together the open ends 44 of the first plates 14 are oriented at 90 degrees to the open ends 56 of the second plates 16. Accordingly, the end portions 46 of the first plates 14 are aligned with the end portions 58 of the second plates 16 to form corners of the heat exchanger core 12.
  • Flange portions 50 of the first plates 14 rest on the top wall 52 of the adjacent second plate 16 along the corresponding open end 56 thereof.
  • the flange portions 64 of the second plates 16 rest on the top wall 40 of the adjacent first plate 14 along the corresponding open end 44 thereof.
  • Flange portions 50, 64 allow for an appropriate amount of surface contact between the respective first and second plates 14, 16 to create a good seal between the components when the first and second plates 14, 16 are joined together by brazing (or by any other suitable method).
  • the stacking of the first and second plates 14, 16 creates a first set of flow channels between the open ends 44 of the first plates 14 for the flow of a first fluid therethrough. Similarly, a second set of flow channels is created between the open ends 56 of the second heat exchange plates 16 for the flow of a second fluid therethrough. As the open ends 44, 56 of the first and second plates 14, 16 are oriented at 90 degrees to one another, the flow of the first fluid is transverse to the flow of the second fluid through the heat exchanger core 12. Cooling fins 18 are located in the first set of flow channels created between the first and second plates 14, 16 to help increase heat exchange between the first and second fluids. When used as the radiator of an internal combustion engine, the first fluid is usually air and the second fluid is coolant.
  • manifold members 20, 22 are located at the respective ends of the heat exchanger core 12.
  • Manifold members 20, 22 are each formed of a generally U-shaped body having a rear wall 66, a pair of lateral walls 68, and open upper and lower ends 70.
  • the manifold members 20, 22 are sized so as to fit snugly around the heat exchanger core 12.
  • the lateral walls 68 have end portions 72 which include the planar inner end surfaces 73 of the lateral walls 68 proximal to the end edges 74 thereof. With the manifold members 20, 22 in place on the heat exchanger core 12, the end portions 72 are adapted to overlap and engage the aligned end portions 46, 58 of the first and second heat exchange plates 14, 16 in a fluid tight manner.
  • manifold members 20, 22, and in particular, the inner end surfaces 73 contact both the end edges 47, 48, 49 of the first heat exchange plates 14, and the planar regions 60 of the second heat exchange plates 16. Accordingly, manifold members 20, 22 create butt joints with the first heat exchange plates 14 and lap joints with the second heat exchange plates 16.
  • the open upper and lower ends 70 of manifold members 20, 22 are closed by top and bottom end plates 28, 36 to form the heat exchanger 10 as described above in connection with Figure 1 .
  • FIG 4 illustrates a variation to the heat exchanger core 12 shown in Figures 2 and 3 , where similar reference numerals have been used to identify similar features.
  • heat exchanger core 12' is comprised of an alternating stack of modified first heat exchange plates 14' and second heat exchange plates 16.
  • First heat exchange plates 14' are also formed of inverted, generally U-shaped bodies with top wall 40, two downwardly depending closed peripheral side walls 42' and open ends 44.
  • closed peripheral side walls 42' have been modified to have a tapered or triangular profile. Therefore, the end portions 46' of first plates 14' include the shaped end edges 48' of the modified side walls 42' as well as the end edges 47', 49' of a portion of the top wall 40 and flange portion 50'.
  • the shaping of the side walls 42' forms a sloping or funnel-like structure surrounding the open ends 56 of the second heat exchange plates 16, when the first and second plates 14', 16 are stacked in their alternating relationship.
  • the funnel-like structure created by the triangular profile of the side walls 42' helps to minimize entrance pressures losses into the second set of flow channels in the heat exchanger core 12' formed by the second heat exchange plates 16.
  • Manifold members 20, 22 are positioned on the respective ends of heat exchanger core 12' in a similar manner as described in connection with the embodiment shown in Figure 2 . Accordingly, manifold members 20, 22 create butt joints and lap joints with the respective end portions 46', 58 of the first and second heat exchange plates 14', 16.
  • FIG. 5 shows an embodiment of the heat exchanger core 12" of the present invention, which includes additional features to help facilitate the assembly of the heat exchanger core 12".
  • the core 12" is formed of an alternating stack of modified first exchange plates 14" and the standard second heat exchange plates 16.
  • First heat exchange plates 14" are similar to those described in connection with the embodiment shown in Figure 4 ; however, in this embodiment, the closed peripheral side walls 42" are double-backed on themselves. Therefore, side walls 42" of the first heat exchange plates 14" are of at least twice the thickness of the side walls 42, 42' shown in the previously described embodiments. The added thickness to the side walls 42" not only increases the strength of the side walls, but the double-wall thickness also increases the surface area of end edges 48", 49" of end portions 46" of the first heat exchange plates 14".
  • the side walls 42" of the first plates 14" further include offset portions 76 that precede and project slightly beyond the base of flange portions 50". Offset portions 76 help position first plates 14" with respect to the second plates 16 as they are stacked in their alternating relationship. As first plates 14" are positioned on top of second plates 16, offset portions 76 abut the end edge of top wall 52, thereby aligning the first plate 14" with respect to the associated second plate 16. Accordingly, the first and second heat exchange plates 14", 16 are considered to be "self-fixturing". While the "self-fixturing" features of the heat exchange plates have only been described in connection with the embodiment shown in Figure 5 , it will be understood that similar features can be incorporated into the other embodiments described herein.
  • manifold members 20, 22 are positioned on the respective ends of the heat exchanger core 12" in a similar manner as described in connection with the heat exchanger shown in Figure 2 . Therefore, manifold members 20, 22 create butt joints and lap joints with the respective end portions 46", 58 of the first and second heat exchange plates 14", 16. Since the end edges 48" of side walls 42" are twice as thick as the side wall end edges shown in the previously described embodiments, it is possible to achieve a more robust butt joint when the components are joined together, for example, by brazing. This helps to ensure that a fluid tight seal is created between the heat exchanger core 12' and the manifold members 20, 22.
  • heat exchanger core 112 is formed of a plurality of stacked, alternating first and second heat exchanger plates 114, 116.
  • first heat exchange plates 114 are formed of inverted, generally U-shaped channel members each having a top wall 140, two downwardly depending closed peripheral side walls 142, and open ends 144.
  • the closed peripheral side walls 142 have end portions 146 which, in this case, include planar regions 78 on the surface of side walls 142 proximal to the end edges 148 thereof (See Figure 6A ).
  • the closed peripheral side walls 142 also include inwardly bent flange portions 150 for resting on the adjacent second heat exchange plate 116 when the first and second plates 114, 116 are alternatingly stacked together.
  • the second heat exchange plates 116 are also formed of inverted, generally U-shaped channel members each having a top wall 152, two downwardly depending closed peripheral sidewalls 154, and open ends 156.
  • the closed peripheral side walls 154 have end portions 158 which, as described in connection with Figure 2 , include planar regions 160 of the side walls 154 adjacent the end edges 162 thereof (See Figure 6B ).
  • the closed peripheral side walls 154 also include inwardly bent flange portions 164 for resting on the adjacent first heat exchange plate 114 when the first and second plates 114, 116 are stacked together in their alternating relationship.
  • the first and second heat exchange plates 114, 116 are alternatingly stacked together so that the open ends 144 of the first plates 114 are at 90 degrees to the open ends of the second plates 116.
  • the first plates 114 are designed so as to be wider than second plates 116
  • second plates 116 are designed so as to be longer than first plates 114. Accordingly, end portions 146 of the first plates 114 overhang the side walls 152 of the second plates 116 by a distance D1, and end portions 158 of the second plates overhang the side walls 142 of the first plates 114 by a distance D2.
  • end portions 146 and 158 align in such a way so as to form corners of the heat exchanger core 120 defined by planar regions 78 and 160.
  • the corners formed by planar regions 78, 160 of the first and second heat exchange plates 114, 116 are substantially 90 degree recessed corners for receiving corresponding ends of the associated manifold members.
  • cooling fins 118 are positioned in the first set of flow channels created between the open ends 144 of the first heat exchanger plates 114 to increase heat exchange through the core 112.
  • manifold members 120, 122 are positioned at respective ends of the heat exchanger core 112.
  • Manifold members 120, 122 are each formed of a generally U-shaped body having a rear wall 166, a pair of lateral walls 168, and open upper and lower ends 170.
  • the manifold members 120, 122 are sized so as to fit snugly around the heat exchanger core 112 and the lateral walls 168 have end portions 172 which correspond to and are adapted to engage the corners of the core 112.
  • end portions 172 of the lateral walls 168 include an outwardly bent first end surface 80, and a second end surface 82 which includes a planar region of the inner surface of the lateral walls 168.
  • the first end surface 80 corresponds to and engages with planar regions 78 on the first plates 114
  • the second end surface 82 corresponds to and engages with planar regions 160 on the second plates 116 (See Figure 7 ). Therefore, in this embodiment, manifold members 120, 122 create lap joints with both the first and second heat exchange plates 114, 116, which further improves the fluid tight seal created between the manifold members 120, 122 and the heat exchanger core 112 when the components are joined together, such as by brazing.
  • the open upper and lower ends 170 of manifold members 20, 22 are closed by top and bottom end plates to form the heat exchanger as described above in connection with Figure 1 and understood by those skilled in the art.
  • Figure 8 illustrates a variation of the embodiment shown in Figures 6 and 7 .
  • the heat exchanger core 112 is the same as described in connection with Figure 6 ; however, manifold members 120', 122' have been modified.
  • the end portions 172' are formed of inwardly bent portions of the lateral walls 168 that have been bent at a first right angle to create the first end surface 80', which extends generally perpendicular to lateral walls 168, and bent at a second right angle to create the second end surface 82', which extends into the opening of the manifold member parallel to lateral walls 168 (See Figure 8A ).
  • First end surface 80' corresponds to and mates with planar regions 78 on the first heat exchange plates 114
  • second end surface 82' corresponds to and mates with planar regions 160 on the second heat exchange plates 116 (See Figure 9 ). Therefore, in this embodiment, manifold members 120', 122' also create lap joints with both the first and second heat exchange plates 114, 116 thereby ensuring a more robust seal between the components when they are joined together.
  • the open upper and lower ends 170 of manifold members 120', 122' are closed by top and bottom end plates to form the heat exchanger as described above in connection with Figure 1 and understood by those skilled in the art.
  • FIG 10 illustrates a further variation of the heat exchanger core 212 shown in Figures 2 to 4 . Similar reference numerals have been used to identify similar features of the heat exchanger core; however, the reference numerals used to identify the features of the first heat exchange plates have been increased by a factor of two hundred.
  • heat exchanger core 212 is comprised of an alternating stack of modified first heat exchange plates 214 and the standard second heat exchange plates 16.
  • First heat exchange plates 214 are formed of inverted generally U-shaped bodies having a top wall 240, two downwardly depending closed peripheral side walls 242 and open ends 244. However, in this embodiment the downwardly depending closed peripheral sidewalls 242 terminate with outwardly bent flange portions 84 as opposed to the inwardly bent flange portions 50 shown in Figure 2 .

  • Manifold members (not shown) are positioned on the respective ends of heat exchanger core 212 in a similar manner as described in connection with the heat exchanger shown in Figure 2 . Accordingly, the manifold members create butt joints and lap joints with the respective end portions 246, 58 of the first and second heat exchange plates 214, 16.
  • FIG 11 shows a variation to the heat exchanger core 212 shown in Figure 10 .
  • first heat exchange plates 214 can be modified so as to include lateral or side flanges 88. Therefore, in this embodiment, the end portions 246' of first plates 214 include the side flanges 88 (see Figure 11A ) and optionally a portion of the end edges 247 of the top wall 240. The addition of side flanges 88 provides additional surface area for joining with the manifold members 20, 22 (not shown) when the heat exchanger components are brazed together.
  • the heat exchanger core 212 shown in Figure 11 includes turbulizers 90 in the second set of flow channels created between the open ends 56 of the second heat exchange plates 16.
  • the turbulizers 90 create turbulence in the fluid flowing through the second set of flow channels which increases the rate of heat transfer. While turbulizers 90 have only been shown in the heat exchanger illustrated in Figure 11 , it will be understood that turbulizers 90 or any other heat transfer augmentation device can be used in any of the embodiments of the present invention.
  • FIG. 12 there is shown yet another a heat exchanger core 312.

  • the heat exchanger core 312 is comprised of an alternating stack of modified first heat exchange plates 314 and the standard second heat exchange plates 16.
  • First heat exchange plates 314 are formed of inverted generally U-shaped bodies with top wall 340, two downwardly depending closed peripheral side walls 342 and open ends 344.
  • the side walls 342 are shaped so as to have an inwardly spiraling circular profile. Therefore, end portions 346 of first plates 314 include the end edges 347 of a portion of the top wall 340 as well as the end edges 348 of the circular side walls 342 (see Figure 12A ).
  • Manifold members 20, 22 are positioned on the respective ends of the heat exchanger core 312 in a similar manner as described above in connection with the various other embodiments. Therefore, as manifold members 20, 22 are positioned on the core 312, they create both butt joints and lap joints with the respective end portions 346, 58 of the first and second heat exchange plates 314, 16. However, in this heat exchanger, the inwardly spiraling circular side walls 342 provide almost twice as much surface area for creating the butt joints with the manifold members 20, 22 when the components are joined together. The circular side walls 342 also provide a certain give or spring-like action when assembling the heat exchanger core 312, which assists in the assembly of the device.
