Definitions

  • the invention relates to a stacked plate heat exchanger, especially for a motor vehicle, with several conduit devices, especially flat pipes, stacked one on top of the other and connected to each other, especially brazed, in the form of elongated plates that are assembled from two elongated plate halves forming a hollow space for passage of the medium and each having at their ends a first through hole for supplying or discharging the medium, wherein this through hole, viewed in the transverse direction of the plate halves, is arranged between two additional through holes.
  • a plate heat exchanger is known from European Patent No. EP 0 470 200 B1 which in the finished state has a number of channels connected in series via manifolds and used for a cooling fluid.
  • Each individual channel is composed of a pair of rounded rectangular plates, which are equipped with projecting and outwardly flanged channels and are turned towards each other.
  • the rectangular plates are equipped with bores that are arranged on the short sides and form the manifolds. Spacers that form slotted direct-connection openings for a coolant are arranged between pairs of plates.
  • a separator is provided between each pair of plates in the area of a corresponding short side.
  • the spacers and the separators are arranged in the same area so that said plates and spacers are connected to each other through a furnace brazing process into a solid body on each short side of the heat exchanger. After the furnace brazing process, at least one channel is produced in the mentioned area that passes through the plates and through the spacers/separators and is provided to be used in connection with installation of the heat exchanger/cooler.
  • the plates and the spacers/separators are provided with two through holes that are symmetrically arranged relative to the openings and recesses, so that during the production process four pipes, having an outer diameter that allows a sliding fit in the so-called bores, are stationarily arranged such that the plates and the spacers/separators on the pipes can be suspended in a desired sequence.
  • four pipes having an outer diameter that allows a sliding fit in the so-called bores
  • the ends of the pipes are stood upright in order to guarantee that the stacked plates and the spacers/separators are held reliably, after which the furnace brazing process is performed.
  • the known plate heat exchanger comprises many individual parts and has a complicated construction. In addition, the production of the known plate heat exchanger is relatively complicated.
  • the task of the invention is to create a stacked plate heat exchanger, which is also designated as a plate heat exchanger, especially for a motor vehicle, with several conduit devices, especially flat pipes, stacked one on top of the other and connected to each other, especially brazed, in the form of elongated plates that are assembled from two elongated plate halves forming a hollow space for passage of the medium and each having at their ends a first through hole for supplying and discharging the medium, wherein this through hole, viewed in the transverse direction of the plate halves, is arranged between two additional through holes; and which is constructed simply and can be produced economically.
  • a stacked plate heat exchanger especially for a motor vehicle, with several conduit devices, especially flat pipes, stacked one on top of the other and connected to each other, especially brazed, in the form of elongated plates that are assembled from two elongated plate halves forming a hollow space for passage of the medium and having at each of their ends a first through hole for supplying and discharging the medium, wherein this hole, viewed in the transverse direction of the plate halves, is arranged between two additional through holes such that the edge area of the additional through holes is formed raised and has essentially the shape of a pot with a base in which the associated through hole is opened.
  • the raised edge areas of the additional through holes take over the function of the separators of the known stacked plate heat exchanger. The separators can thus be eliminated.
  • a preferred embodiment of the stacked heat exchanger is characterized in that the edge area of the first through hole is raised and has essentially the shape of a pot with a base in which the associated through hole is opened.
  • the raised edge region of the first through hole takes over the function of the spacer of the known stacked plate heat exchanger. The spacer can thus be eliminated.
  • a bead is formed between the raised edge areas of the additional through holes and the raised edge area of the first through hole.
  • the bead improves the solderability of a plate pair.
  • the strength of a plate half is increased by the bead.
  • the bead is constructed with a slight spacing, so that both sides of a plate half are connected to the respective adjacent plate half by the bead. Therefore, strong ties are formed in the brazed stacked plate heat exchanger.
  • Another preferred embodiment of the stacked plate heat exchanger is characterized in that the beads are connected to each other by a meander-shaped impression or lock-bead, which is formed towards the end of the appropriate plate half between the two additional through holes outside of the first through hole.
  • the meander-shaped impression or lock-bead can also be designated as a bead and reinforces the previously described effect of the bead.
  • Another preferred embodiment of the stacked plate heat exchanger is characterized in that the conduit devices are stacked between a base plate and a cover plate.
  • the cover plate and the base plate delimit the stacked plate heat exchanger.
  • One of the plates or both plates can be used to mount the stacked plate heat exchanger, for example, on or in an engine block or filter housing.
  • the base plate has four through holes that are respectively arranged concentrically with the additional through holes in the conduit devices and used for the passage of attachment means whose dimensions are somewhat smaller than the diameter of the additional through holes.
  • the attachment means preferably involve bolts with which the base plate is bolted onto an engine block, for example.
  • the bolts preferably have bolt heads whose outer diameter is greater than the diameter of the through holes in the base plate, but smaller than the diameter of the additional through holes in the conduit devices.
  • the base plate and the cover plate each have four through holes that align with the additional through holes in the conduit devices and are used for the passage of attachment means whose dimensions are somewhat smaller than the diameter of the additional through holes.
  • the attachment means preferably involve bolts with which both the base plate and also the cover plate are bolted, for example, to an engine block with the conduit devices clamped in-between.
  • the bolts preferably have bolt heads whose outer diameters are greater than the diameters of the through holes in the base plate and the cover plate.
  • the conduit devices are each assembled from two equal plate halves rotated relative to each other by 180°, of which each has a plurality of grooves that preferably run in straight lines from one longitudinal side to the opposite longitudinal side of the plate half.
  • the plates, each assembled from two plate halves, are also designated as flat pipes or plates.
  • the stacked plate heat exchanger is therefore also designated as a plate heat exchanger.
  • the straight-line profile of the grooves guarantees unimpaired passage of a medium from one longitudinal side of the plate half to the opposite longitudinal side.
  • the grooves in the hollow space provide good swirling of the medium to be cooled. This provides the advantage that separate turbulence inserts can be eliminated.
  • the grooves are stamped into one side in each plate half.
  • the grooves are formed by straight line, elongated, narrow recesses, which are also designated as beads that are stamped into one side, for example, in a sheet material. Because the grooves are stamped on one side, the production of the plate halves is simplified.
  • Another preferred embodiment of the stacked plate heat exchanger is characterized in that the grooves are delimited on the longitudinal sides by a peripheral edge.
  • the peripheral edge is used to connect, especially to solder, two plate halves to each other.
  • the hollow space between the two plate halves is therefore sealed from the surroundings.
  • a plate is formed by two plate halves contacting each other whose grooves are stamped outwards.
  • the grooves delimit the flow path of the medium in the interior of the plate.
  • Another preferred embodiment of the stacked plate heat exchanger is characterized in that two plates contact each other with their raised areas formed by the grooves and are brazed to each other. Coolant can be led between the raised areas from one longitudinal side to the opposite longitudinal side of the respective plate half.
  • the grooves run at an angle of 35° to 55°, especially 45°, to the longitudinal axis of the associated plate half. In this way it is guaranteed that the medium can flow from one end to the other end of the plate through the hollow space formed in the interior of the plate.
  • the profile of the grooves according to the invention also guarantees that the medium can flow in two plates from one longitudinal side to the opposite longitudinal side.
  • the grooves of two plate halves contacting each other are arranged at an angle of 80° to 100°, especially 90°, relative to each other. Therefore, a flow path which has many changes of direction and swirls is created in the interior of the plates for the medium to be cooled.
  • This has the advantage that boundary layers forming in the hollow space during operation are always torn open again. This leads to greatly improved heat transfer in comparison with a smooth channel without grooves.
  • the medium to be cooled is subjected to many changes in direction while flowing through the hollow space.
  • the coolant can flow nearly unimpaired and in a straight line through the grooves between two plates contacting each other.
  • the angle of 90° produces a nearly circular solder meniscus at the connecting point of two grooves. In this way, the flow along and transverse to the main direction of flow of the medium to be cooled is affected equally.
  • Each of the through holes is, for example, round, elliptical, oval, polygonal, in particular, triangular, quadrangular, polygonal, rectangular or square.
  • the through holes here have in some circumstances a different form and/or size relative to each other.
  • a plate heat exchanger especially for a motor vehicle, comprising several conducting devices, above all flat pipes, in the form of elongate disks which are stacked on top of each other, are interconnected, particularly soldered together, and are composed of two elongate half disks that form a hollow space for conducting a medium therethrough.
  • Each end of each half disks is provided with a first through-hole for feeding or discharging the medium, each through-hole being disposed between two other through-holes from the perspective of the transversal direction of the half disks.
  • an edge region of the other through-holes is embodied in a raised manner and is substantially provided with the shape of a pot encompassing a bottom in which the associated through-hole is recessed.
