Definitions

  • the present disclosure relates to the field of thermal transfer, in particular to a heat exchanger.
  • Heat exchangers have been known for transferring heat from one fluid to another.
  • the fluids enter the heat exchanger through respective ports, flow in separated channels and leave the heat exchanger through other respective ports.
  • various designs have been proposed for the ports.
  • a heat exchanger comprising: a parting plate comprising a frame and a main body arranged within the frame and connected to the frame so as to define, between the frame and the main body, two first ports and two second ports; at least one first channel extending from one of the first ports to another one of the first ports on a first face of the main body; first edge bars extending on either sides of the at least one first channel to prevent communication between the at least one first channel and the second ports; wherein the at least one first channel opens out onto a first rectilinear portion of one of the first ports, and at least one of the first edge bars extends up to the first rectilinear portion.
  • the heat exchanger is configured to carry out heat transfer between a first fluid and a second fluid.
  • the first fluid is configured to enter and leave the heat exchanger through the first ports, and to flow through the at least one first channel, on the first face of the main body.
  • the second fluid is configured to enter and leave the heat exchanger through the second ports, and to flow on a second face of the main body.
  • the parting plate may be a part having the general shape of a plate.
  • the parting plate in particular the main body, may be devoid of any opening other than the aforementioned ports.
  • the main body may be solid. In other words, the main body solidly separates the two faces thereof.
  • the ports are through holes of the parting plate.
  • the first edge bars are arranged on the first face of the parting plate in order to prevent communication between the first channels, on the first face of the main body, and the second ports.
  • the at least one first channel opens out onto a first rectilinear portion of one of the first ports.
  • the at least one first channel extends up to the first rectilinear portion. Therefore, the first channel can easily match the shape of said first port, thus providing appropriate flow guide and mechanical support.
  • the first edge bars extends up to the first rectilinear portion
  • the first edge bar is adjacent to the first port and supports possible non-rectilinear portions of the first port. Therefore, mechanical support is also provided for the non-rectilinear portions.
  • the inventors have therefore judiciously enhanced the support of the parting plate by allocating this support to both the first channels and the first edge bar.
  • the at least one first channel opens out onto the first rectilinear portion in a direction substantially orthogonal to the first rectilinear portion.
  • substantially encompasses a variation of +/- 15°, preferably +/-10°, yet preferably +/-5°.
  • the first channel extends in a direction substantially orthogonal to the first rectilinear portion.
  • the first channel may be rectilinear itself, or may form waves centered on the orthogonal direction.
  • the first channel provides a stronger mechanical support for the main body of the parting plate, as compared to a situation in which the first channel would open out onto the first rectilinear portion in a more oblique direction.
  • the first edge bars are substantially parallel to the at least one first channel. Therefore, the interface between the first channel and the first edge bar is mechanically strong too.
  • an end portion of the at least one of the first edge bars supports a rounded corner of said one of the first ports.
  • a rounded corner is advantageous for avoiding stress peaks, and is all the more advantageous that it is properly supported by the first edge bar.
  • the at least one of the first edge bar overlaps a projection of the one of the first ports orthogonal to the first rectilinear portion.
  • the first edge bar and the first port extend along a common segment in the direction of the first rectilinear portion.
  • the one of the first ports extends towards the first edge bar beyond the first rectilinear portion.
  • the at least one of the first edge bar is flush with one of the second ports.
  • the first edge bar may be arranged adjacent to at least one of the second ports, and is flush thereto.
  • the first edge bar may be arranged between the first channel and the second port. Thanks to these provisions, the first edge bar supports the parting plate in the region of the second port while not impeding the flow of the second fluid through the second port.
  • an edge of the one of the first ports adjacent to the first rectilinear portion is tangent to the first rectilinear portion. Therefore, the first port can suitably guide the first fluid towards the first rectilinear portion, so towards the first channels.
  • a tangent edge limits stress peaks.
  • the at least one first channel and/or the first edge bars are assembled to the parting plate by brazing.
  • Brazing is known per se in the art. Other techniques may be used such as welding, diffusion bonding, etc.
  • the at least one first channel is formed by a corrugated plate.
  • the corrugated plate may define a plurality of parallel channels between consecutive corrugations of the corrugated plate.
  • the corrugated plate may be obtained by pressing or bending.
  • the heat exchanger further comprises at least one second channel extending from one of the second ports to another one of the second ports on a second face of the main body, and second edge bars extending on either sides of the at least one second channel to prevent communication between the at least one second channel and the first ports.
  • the second channel may have any of the features described herein as regards the first channel, mutatis mutandis.
  • the at least one second channel opens out onto a second rectilinear portion of one of the second ports, and at least one of the second edge bars extends up to the second rectilinear portion.
  • the second edge bar may have some or all of the features described herein as regards the first edge bar, mutatis mutandis.
  • the at least one of the first edge bars and the at least one of the second edge bars are superimposed with each other, on either side of a junction between the frame and the main body. Therefore, the first edge bar and the second edge bar both support the junction, which may be a mechanically weaker portion of the parting plate. Accordingly, the mechanical strength of the heat exchanger is improved.
  • the at least one of the first edge bars and the at least one of the second edge bars are substantially orthogonal to each other.
  • the first and second rectilinear portions may be substantially orthogonal to each other.
  • the first and second channels may extend substantially orthogonal to each other in a region of opening out onto the first and second ports, respectively.
  • the disclosed heat exchanger may comprise at least one of the following features, taken alone or in any technically possible combination:
  • a heat exchanger 100 according to an embodiment is described with reference to Figs. 1-4 .
  • the heat exchanger 100 enables heat transfer between a first fluid and a second fluid.
  • the heat exchanger 100 comprises at least one parting plate 10 having two first ports and two second ports, namely a first inlet port 12, a first outlet port 14, a second inlet port 16 and a second outlet port 18.
  • the parting plate 10 prevents the fluids from mixing: specifically, the first fluid is configured to flow through the first inlet port 12, circulate on a first face 21 of the parting plate 10, and exit through the first outlet port 14.
  • the second fluid is configured to flow through the second inlet port 16, circulate on a second face 22 of the parting plate 10, opposite the first face 21, and exit through the second outlet port 16. Heat exchange takes place by convection of the fluids along the parting plate 10.
  • the heat exchanger 100 may have a layered structure. Besides the parting plate 10, the heat exchanger 100 may comprise at least one first plate 31 and at least one second plate 32. The first plate 31 and the second plate 32 may be stacked in an alternate manner, with a parting plate 10 being provided between each first plate 31 and each second plate 32 adjacent thereto. In other words, a minimum stacking may comprise, in order, one first plate 31, one parting plate 10 and one second plate 32, as shown in the top portion of Fig. 1 .
  • a further subset comprising, in order, a parting plate 10, a first plate 31, a parting plate 10 and a second plate 32, may be stacked next to the minimum stacking, N times as shown in the bottom portion of Fig. 1 (N being zero or a non-zero positive integer).
  • each one of the first and second plates 31, 32 is provided with first and second ports 12, 14, 16, 18 respectively in fluid communication with the first and second ports 12, 14, 16, 18 of the adjacent parting plates 10.
  • the resulting stack may be flanked by end plates, for instance an open end plate 33 and a closed end plate 34.
  • the end plates may be made of one or several elements.
  • the open end plate 33 is provided with first and second ports 12, 14, 16, 18 respectively in fluid communication with the first and second ports 12, 14, 16, 18 of the adjacent parting plate 10.
  • the closed end plate 34 is solid and forms a closed bottom 12a, 14a, 16a, 18a for the first and second ports 12, 14, 16, 18 of the stack. In this way, when entering the heat exchanger 100 through the first inlet port 12, the first fluid must cross one of the first plates 31 in order to access the first outlet port 14. The same applies, mutatis mutandis, to the second fluid.
  • the heat exchanger could include a first end plate having a first inlet port 12 and a first outlet port 14 and a closed bottom 16a, 18a for the second inlet port 16 and the second outlet port 18 of the stack, and a second end plate having a second inlet port 16 and a second outlet port 18 and a closed bottom 12a, 14a for the first inlet port 12 and the first outlet port 14 of the stack. Further arrangements are possible, as long as the fluids do not mix with each other and flow along the parting plate 10 in order to exchange heat with each other.
  • Ports of the end plates 33, 34 may have a different shape than the shape of the ports of the parting plate 10 in order to interface with systems external to the heat exchanger 100.
  • the first fluid may be a gaz.
  • the second fluid may be a gaz.
  • the first fluid may flow at a pressure less than the second fluid; for this reason, the first ports 12, 14 may be bigger than the second ports 16, 18.
  • the opposite situation is envisaged as well.
  • the components of the heat exchanger 100 may be metallic, e.g. made of stainless steel or nickel-based alloys.
  • a parting plate 10 according to an embodiment is described in more details with reference to Fig. 2 .
  • the parting plate 10 comprises a frame 20 and a main body 24.
  • the frame 20 may be formed by a rim forming a closed contour.
  • the main body 24 is arranged within the frame 20 and connected to the frame 20 so as to define, between the frame 20 and the main body 24, the aforementioned first inlet port 12, first outlet port 14, second inlet port 16 and second outlet port 18.
  • the first inlet port 12 and the first outlet port 14 are provided on opposite sides of the main body 24.
  • the second inlet port 16 and the second outlet port 18 are provided on opposite sides of the main body 24.
  • the main body 24 forms a main heat transfer area of the parting plate 10.
  • the main body 24 is connected to the frame 20 at one or more localized junctions 26. Between two consecutive junctions 26, the space between the frame 20 and the main body 24 defines one of the ports.
  • the frame 24 forms lobes 28 (respectively 282, 284, 286, 288) around the ports.
  • the lobes 28 project from the main body 24 and may have a rounded shape.
  • a width W of the frame 20 from one of the lobes 28 to an adjacent lobe 28 is substantially constant.
  • Fig. 2 shows that the width W of the frame 20 does not vary by more than 35% from a reference value, from the lobe 282 including the first inlet port 12 to an adjacent lobe, here the lobe 288 including the second outlet port 18.
  • the width W is measured as the smallest dimension of the frame 20 in the plane in which the lobe 28 protrudes from the main body 24.
  • the frame 20 is concave between the lobe 282 and the adjacent lobe 288.
  • the frame 20 forms a concave portion 30 where the frame 20 gets inwards with respect to the lobes 28 and closer to the main body 24.
  • the concave portion 30 helps keeping a substantially constant width W while ensuring a good junction with the main body 24.
  • At least one of the first inlet port 12, the first outlet port 14, the second inlet port 16 and the second outlet port 18 of the parting plate 10 has a substantially triangular shape, with three main sides and corners (here rounded corners) in-between.
  • other port shapes are contemplated, in particular polygonal-like port shapes.
  • a first plate 31 according to an embodiment is now described in more details with reference to Fig. 3 .
  • the first plate 31 comprises a frame 20 similar to the frame 20 of the parting plate 10.
  • the respective frames 20 of the first plate 31 and the parting plate 10 superimpose in order to form a continuous wall for the heat exchanger 100.
  • the first plate 31 has ports 12, 14, 16, 18 corresponding to the respective ports 12, 14, 16, 18 of the parting plate 10.
  • the ports of the first plate 31 superimpose to the ports of the parting plate 10: they may be identical in shape.
  • the second inlet port 16 and the second outlet port 18 are each isolated by a first edge bar 35.
  • the first edge bar 35 extends between two distant portions of the frame 20.
  • each of the second inlet port 16 and the second outlet port 18 is defined between the frame 20, and more particularly a lobe 28 thereof, and a first edge bar 35.
  • the first edge bar 35 may be formed integrally with the frame 20 of the first plate 31.
  • the first edge bar 35 may be flush with the corresponding second port 16, 18, so that the respective second ports 16, 18 of the first plate 31 and of the parting plate 10 are identical in shape, as mentioned above.
  • the first inlet port 12 and the first outlet port 14 are in fluid communication with one another. This enables the first fluid to flow from the first inlet port 12 to the first outlet port 14 across the first plate 31.
  • the first fluid may flow between the two first edge bars 35.
  • the first edge bars 35 form, between them, a first channel 37 extending from one of the first ports (here the first inlet port 12) to another one of the first ports (here the first outlet port 14) on a first face 21 of the main body 24.
