Description

  • The invention relates to a plate heat exchanger, in particular an oil / coolant cooler for internal combustion engines according to the preamble of patent claim 1.
  • By the US-A 4,708,199 a plate heat exchanger has been known with circular stacked plates of the same shape. This circular stacked plate heat exchanger is provided for the cooling of engine oil by coolant and is attached by means of a centrally located tube on the engine block. This type of disc oil cooler is installed in each case with a coaxial with the central pipe arranged oil filter, the oil inlet and -abströmöffnungen are adapted to this special design. The passage openings for the first fluid (engine oil) and the second fluid (water) are each on a common circle, wherein the passage openings have the same distance or circumferential angle to each other on the circumference of the common circle. In the passage openings each changes a simple passage opening with a passage opening with collar or expression. When assembling the circular heat exchanger adjacent plates are each rotated by the pitch of adjacent passage openings, so that at least two passageways for the oil and at least two passageways for the coolant form. This construction is based on the fact that all plates are circular, have an annular raised edge and are pivotable about a common axis.
  • It is from the EP-B1-258,236 known to provide the plates of a plate heat exchanger with circumferential edges, which interlock at several stacked plates so that they can be soldered tight by a soldering process. It is also known, a plate heat exchanger to supply two fluids, a working and a cooling medium, in each case via two connecting pieces, wherein after the above EP-B1-258,236 the outer plate, to which the connecting pieces are fastened, is stabilized by a support plate.
  • A disadvantage of the aforementioned prior art that a large number of individual parts is required for such a plate heat exchanger. The different design of the individual plates of the heat exchanger is in this case particularly costly, since for each plate shape own pressing tools are needed. In addition, the assembly of the heat exchanger is difficult because the different plates must be mounted in a particular order.
  • The invention is therefore the object of a plate heat exchanger of the type mentioned in such a way that the number of common parts used increases, or the number of parts used is reduced overall.
  • To solve this problem, a plate heat exchanger with the features of claim 1 is proposed in which turbulence inserts are arranged in the heat exchanger plates.
  • The proposed in claim 1 embodiment reduces the number of heat exchanger plates used, so that all plates can be manufactured with the same tool. A special housing for the plate heat exchanger is not needed, since the peripheral edges of the heat exchanger plates are joined by joining technology, for example, soldered, and thus form a housing-like outer shell of the plate heat exchanger. From this construction results as a further distribution that leakage at the joints leads only to a discharge of a fluid, but mixing of the fluids is excluded.
  • According to claim 1, the design of the gap between two stacked heat exchanger plates by the use of different turbulence inserts, is varied. In this way, the plate heat exchanger can be very easily adapted to different fluids or different uses (eg low pressure loss or high heat exchange performance). The heat exchanger plates, the turbulence inserts and all other attachments can be made of the same material, whereby a recycling of the heat exchanger is very easy. On the other hand, individual components can also be made of different materials, whereby adaptation to special applications is greatly facilitated.
  • For example, turbulence-generating elevations are embossed in the heat exchanger plate. This embodiment avoids the insertion of a single turbulence insert and significantly reduces the number of parts used.
  • According to claim 2, the heat exchanger plates can be combined by the U-shaped design of the characteristics with heat exchanger plates that still need sealing washers.
  • According to claims 1 and 3, the plate heat exchanger is provided with a closure plate having two openings corresponding to two corresponding openings in the heat exchanger plates. With this configuration, the supply and discharge of a fluid from the top and that of the other fluid from the bottom can be carried out. This is particularly advantageous in the case that the plate heat exchanger is provided at the bottom with connecting pieces, which have a smooth shaft with an incorporated groove into which a sealing ring is inserted. Such a plate heat exchanger can be connected by simple plug-in assembly to the oil circuit of a motor or gearbox. The attachment to a motor or gearbox takes place by suitable means. Thus, according to claim 4, a special mounting plate is provided on the plate heat exchanger, which can be produced inexpensively according to customer requirements.
  • According to claim 5, already has the end plate formations and openings for attachment of the plate heat exchanger to another body. A special mounting plate is thereby superfluous. The formations and openings of the end plate are manufactured according to the respective customer requirements. Thus, only the end plate is designed customer-specific for plate heat exchangers of the same power. Particularly advantageous and inexpensive, the end plate is designed as a deep-drawn sheet metal part. In addition to a saving in material and processing costs, such an embodiment also leads to a significant reduction in weight. The openings that must be introduced into the end plate can be stamped in a deep-drawn sheet metal part, so that a complex, machining production is not necessary.
  • According to claim 6, an insert and a cover plate is inserted between the end plate and the adjacent heat exchanger plate. The cover plate covers at least one opening of the heat exchanger plate fluid-tight, so that a deflection of the fluid is ensured within the space between two heat exchanger plates. On the other hand, the cover plate openings, which allow a connection of the fluid channels of the plate heat exchanger to the connection piece. The connecting pieces, for example, an embodiment with a smooth shaft, are inserted into the end plate of the plate heat exchanger and connected by joining technology with the end plate.
  • According to claim 7, an insert is inserted between the cover plate and the end plate. This Einlegteil directs the fluid flowing through to the fluid-carrying channels of the plate heat exchanger, or to the connection piece in the end plate. With the help of the insert, the fluid flow can be passed to any arranged connecting piece in the end plate, so that the connecting pieces the fluid channels of the plate heat exchanger need not be opposite. A customized configuration of the plate heat exchanger is facilitated because the geometric conditions at the installation site can be easily taken into account. The insert is fluid-tight and mechanically stable with the cover plate and the end plate by joining technology, in particular soldered.

  • Fig. 1 shows an exploded view of a cut plate heat exchanger not according to the invention 1. Here are between two identical, tub-shaped heat exchanger plates 3 each a turbulence insert 4 or 4 'and two annular sealing discs 5 (in section, only a sealing disc 5 is shown). The sealing discs 5 are usually made of a metallic material, but they can also be made of plastic or ceramic. They have the same thickness d as the turbulence inserts 4, 4 'and are inserted in openings 15, 15' of the turbulence inserts 4, 4 ', the inner diameter of the openings 15, 15' corresponding to the outer diameter of the sealing disks 5. The turbulence inserts 4, 4 'are inserted into the trough-shaped heat exchanger plates 3 such that the sealing disks 5 come to lie alternately over the openings 12 and 12', the openings of the sealing disks 5 corresponding to the openings 12, 12 '. The sealing discs 5 seal the openings 12 and 12 'relative to the space between the heat exchanger plates 3 and the turbulence insert 4, 4' therein, so that passageways are formed through which passes the corresponding fluid in the next adjacent space. In the case of the oil / coolant cooler shown here, there is an alternating filling of the intermediate spaces with coolant, oil, sensor means, etc. The distribution of the fluid in the intermediate spaces is due to the pressure with which the fluids are pressed into the plate heat exchanger 1, wherein the individual Gaps cause a certain throttling of the fluid flows through the interstices. The uniform distribution of the fluids in the interstices can be controlled by the design of the turbulence inserts 4, 4 '. The supply and discharge lines for the fluids can be arranged in a row (shown here) or diagonally opposite (cross flow). For fluids whose viscosity differs greatly, turbulence inserts 4, 4 'are used, which differ in their design. In the example shown, the turbulence inserts 4 are designed for a coolant and the turbulence inserts 4 'flor an oil. The coolant is via connections 9 zubzw. derived (only one port shown). The terminals 9 are mounted on a terminal plate 2. They are continuous to the openings 12 'of the heat exchanger plates 3 and the openings 14 of the turbulence inserts 4. Each gap oil is sealed by means of the sealing rings 5 against the coolant flow, so that the coolant is passed through in the next space KM. The lowermost heat exchanger plate 3 of the plate heat exchanger 1 is sealed by means of a closure plate 6, so that the coolant is deflected in the plate heat exchanger 1 and 9 flows through the second port again. The supply and discharge of the oil could also be done by means of connections to the connection plate 2. In the example shown, the oil ports 8, however, the coolant ports 9 are arranged obliquely opposite. In this case, openings 13 are provided in the connection plate 6, which correspond to the openings 12 of the heat exchanger plates 3, while the connection plate 2 closes the openings 12 of the uppermost heat exchanger plate 3 tightly. The oil is introduced upper connecting piece 8, which are inserted into the terminal plate 6 and fixedly connected thereto. In this case, the oil is introduced through the ports 8 and the openings 13 and 12 through a gap KM in the first space oil, the gap KM is completed by sealing discs 5 against the flow of oil. A portion of the oil flow is distributed in the space oil, thereby deflected and flows through the second port 8 from. In this case, the oil via the walls of the heat exchanger plate 3 and the turbulence inserts 4 its heat to the coolant in the adjacent spaces KM from. The remaining oil flow is through the next gap KM, which in turn is sealed by sealing discs 5 against the flow of oil, forwarded in the following space oil. The number of heat exchanger plates 3 is chosen so that the required heat exchange performance of the heat exchanger 1 is achieved, it may therefore differ from the example explained here. The connecting pieces 8 have a smooth shaft 10, in which an annular groove 11 is incorporated. The groove 11 serves to receive an O-ring seal. By this configuration, the plate heat exchanger 1 can be mounted by plug-in mounting on, for example, an engine block. For fixing the plate heat exchanger 1 to such an engine block 6 holes 16 are provided in the end plate, by means of which the plate heat exchanger 1 can be screwed to stud bolts for example. The adaptation of the fasteners to specific customer requirements is carried out with the help of an individual mounting plate 7, which is provided in the representation as a cranked plate. The mounting plate 7 can be mounted in addition to the end plate 6, for example, subsequently, or alone on the plate heat exchanger 1, wherein it takes over the function of the end plate 6 in the second case. The stacked heat exchanger plates 3 are joining technically connected to each other at their adjacent peripheral edges, eg soldered or glued, in this case, the inserted sealing discs 5 and the turbulence inserts 4, 4 'are connected. Due to the large number of compounds (eg heat exchanger plates 3 with the turbulence inserts 4, 4 '), the heat exchanger 1 is very stable, since the compounds act in the interstices as tie rods.
  • Fig.2 shows a variant of the heat exchanger plates 3 Fig. 1 in a design corresponding to claim 1. Also in this embodiment of the heat exchanger plates 23 all heat exchanger plates 23 of a plate heat exchanger 1 are the same. However, during assembly of the heat exchanger 1, every second heat exchanger plate 23 is rotated by 180 ° about the vertical axis. Around the openings 26 of the heat exchanger plate 23 annular shapes 25 are formed, which serve to seal the opening 26 with respect to the opening 27. The height h of the forms 25 corresponds to the thickness d of the turbulence inserts 4, 4 '. The head 28 of the embossments 25 is flattened to ensure good contact with the adjacent heat exchanger plate 23, so that the cross section of the embossment 25 has a "U" profile which is greatly flattened at the base of the "U". Between two heat exchanger plates 23, a turbulence insert 4 or 4 '(for coolant or for oil) is arranged, wherein through the larger openings 15, 15' of the turbulence inserts 4, 4 ', the forms 25 of the heat exchanger plate 23 are inserted. The openings 14, 14 'of the turbulence inserts come to lie over the openings 27 and the non-pronounced side of the opening 26. Sealing washers 5 are not required in this embodiment. The handling during assembly and joining of the heat exchanger 1 corresponds to that in the description FIG. 1 illustrated approach.
  • Fig. 3 shows a further variant not according to the invention in FIG. 2 illustrated heat exchanger plate shape. However, this variant facilitates the understanding of the invention. Here, the heat exchanger plates 33 also have annular shapes 35 around the openings 36. In addition, in the heat exchanger plate 33 between the openings 36 and 37 turbulence-generating elevations 39, for example, truncated conical nubs, impressed, which have the same height h as the characteristics 35. The elevations 39 are used in the assembled state of the generation of turbulence, so that it can be dispensed with the introduction of additional turbulence inserts in the intermediate space (here, for example, the gap KM). Around the openings 37 remains a circular area in an unembossed state to serve in the mounted state as a contact surface to the adjacent annular shape 25 of the adjacent heat exchanger plate 23. The heat exchanger plate 33 can with the heat exchanger plates 3 or 23 of the FIGS. 1 and 2 combined, so that find in the spaces oil turbulence inserts use, while in the spaces KM only the embossed projections 39 protrude and provide sufficient turbulence of the coolant. In this variant alternately spaces for coolant and spaces for oil are provided. The mounted heat exchanger is sealed in a single operation at the peripheral edges and at the contact surfaces of the forms 35 with the adjacent heat exchanger plates 23. At the same time, the turbulence inserts 4, 4 'and the elevations 39 are connected to the heat exchanger plates 23, 33.
  • Fig. 4 shows a heat exchanger without separately inserted turbulence inserts 4, 4 'or sealing disks 5 according to claim 2. The heat exchanger plates 43 have around the openings 46 annular shapes 45, the cross-sectional profile is approximately "U" -shaped. Between the openings 46 and 47 and in the remaining edge areas turbulence-generating elevations 49, such as frustoconical knobs, impressed, with a circular area around the openings 47 remains in an unembossed state to a secure seal with an adjacent expression 45 of the adjacent heat exchanger plate 43 guarantee. During assembly, the heat exchanger plates 43 are stacked without additional inserts, with each second heat exchanger plate 43 is rotated by 180 ° about the vertical axis. To increase the heat exchange performance, two different heat exchanger plates 43 'and 43 "(not shown) can be used, in which the turbulence-generating elevations 49 of a heat exchanger plate 43' for use with coolant and the turbulence-generating elevations 49 a second heat exchanger plate 43" on the use tuned with oil.
  • The FIGS. 5 and 6 show a plate heat exchanger with twelve heat exchanger plates 3 in the assembled state. Here, the trough-shaped heat exchanger plates 3 are stacked with each other, with their peripheral edges come to rest each other. In deviation from the construction of the plate heat exchanger 1 in FIG. 1 the connection plate 2 is mounted on the underside of the heat exchanger plate 3, while the end plate 6 (not visible) is arranged with the connection piece 8 and the individual mounting plate 7 on the upper side of the heat exchanger plate 3. The coolant is supplied via the left connection piece 9 and distributed in the heat exchanger 1 to six spaces. After flowing through the gaps, the coolant is discharged via the right connection piece 9 again. The oil flow is analog, wherein the oil supply via the right connection piece 8 and the oil removal via the left connection piece 8. The oil is distributed in the heat exchanger 1 to five spaces and cooled there. The connection of the heat exchanger 1 to eg a motor or gear block via plug-in mounting, wherein the connecting piece 8 with the smooth shanks 10 and the sealing rings 17 which are inserted into the annular grooves 11 are inserted into corresponding receiving bores on the housing of the engine or transmission block , The heat exchanger 1 is fastened there by means of the individual fastening plate 7, for example screwed to corresponding stud bolts. The coolant is supplied via coolant hoses, which are fastened in a known manner to the terminals 9.
  • The FIGS. 7 and 8 show a closure plate 60, which is designed as a deep-drawn sheet metal part. It has two openings 64, 64 ', which serve to supply and discharge of a fluid. Furthermore, four formations 61 are integrally formed with the openings 62 to the end plate 60. They serve to attach the end plate to another body, such as a motor or gear block. The outer edge 63 of the end plate 60 is set up, for example, by deep drawing perpendicular to the bottom surface of the end plate 60, whereby the end plate 60 and the formations 61 are stiffened in itself and a torsion-safe attachment of the end plate 60 is ensured on another body. The end plate 60 is soldered to the heat exchanger plates 3 of the plate heat exchanger 1 fluid-tight.
  • Fig. 9 shows an insert 65 and a closure plate 66. The insert 65 is designed as a deep-drawn sheet metal part. In this case, elevations 67 and an edge 68 are pulled out of the plane of the insert 65 upwards. The elevations 67 and the edge 68 form flow-conducting channels, which conduct a fluid flowing through to the corresponding openings 12, 12 'of the plate heat exchanger 1. The nubs in the center region of the insert-like elevations 67 act on the fluid flowing through turbulence generating. Furthermore, these knob-shaped elevations 67 serve the support of the insert on an adjacent cover plate (not shown). The underside of the insert 65 rests on a closure plate 66. Here, the openings 64, 64 'of the insert 65 correspond with the corresponding openings of the end plate 66. The end plate 66 has at its edges formations 70, which are provided with openings 69 and serve the attachment of the end plate 66 to another body. The end plate 66 and the insert 65 are soldered together and with the heat exchanger plates 3 of the plate heat exchanger 1 fluid-tight and mechanically strong.
  • Fig. 10 shows a partial section through a plate heat exchanger 1 with a plurality of heat exchanger plates 3, a connection plate 2 and a coolant connection 9. The opening 12 'of the lowermost heat exchanger plate 3 is fluid-tightly sealed by a cover plate 71, whereas the opening 12 is arranged above a corresponding opening 72 of the cover plate 71, so that at this point a fluid passage is made possible. The cover plate 71 is in turn fluid-tightly connected to the insert 65, wherein the opening 64 'of the insert 65 is disposed on the openings 12 and 72 of the heat exchanger plate 3 and the cover plate 71. The peripheral edge 68 of the insert 65 is fluid-tightly connected to the cover plate 71 at its edges. The elevations 67 form with the cover plate 71 flow-conducting channels, through which a fluid flowing through mixed and to the openings 64, 64 'is passed.
