Definitions
- the present invention relates to a heat exchanger plate comprising an edge, a groove running along the edge, and a corrugated area having crests and troughs between the groove and the edge, wherein crests run perpendicular to the edge.
- the invention is in particular used for a high-pressure gasket heat exchanger having a stack of such heat exchanger plates, wherein a gasket is arranged between two adjacent plates.
- the corrugated area along the edge forms contact points to the neighbouring plates and at the same time a supporting wall for the gasket.
- the gasket For mounting the heat exchanger the gasket has to be positioned in the groove and the heat exchanger plates have to be positioned one above the other. This can be complicated and requires some skill of a worker, since there is the risk that the gasket leaves the position in the groove when the heat exchanger plates are moved to the stack position.
- the object of the invention is to facilitate mounting of a plate-type heat exchanger.
- the corrugated area comprises at least two of three different sections, wherein in a first section adjacent crests are connected by a first connecting wall, in a second section at least one crest is flanked at both sides by a space between the crests that is open to the groove.
- the heat exchanger plate further comprises a third section that form a click-on tap position.
- the first connecting wall squeezes the gasket and keeps it in place by friction.
- the first connecting wall further assists in making the heat exchanger plate rigid and strong to support high-pressures.
- the second section comprises a space or a plurality of spaces which are open to the groove. Here the material of the compressed gasket is allowed to move into the open spaces assisting in keeping the gasket in position.
- the third section is provided to position a click-on tap in order to secure the gasket in the groove.
- the corrugated area comprises the first section, the second section, and the third section. In this case all three different possibilities are used.
- a bottom of the troughs is coplanar with a bottom of the groove. This is in particular useful in the region of the second section since the gasket has not to be moved over a step which is positive for the lifetime of the gasket and for the tightness of the heat exchanger.
- the first section comprises at least three crests.
- the first connecting wall extends at least over two troughs.
- the squeezing area of the gasket is quite large and the stiffness of the heat exchanger plate in this area is increased.
- the space between the crests is open to the edge.
- the space into which the gasket can move is preferably not limited in a direction towards the edge.
- the crests are shorter than in the first section or the second section. Accordingly, there remains a space between the crests in the third section and the groove which can be used for parts of the click-on tap.
- the crests are connected by a second connecting wall, wherein the second connecting wall has a height smaller than the height of the crests.
- the second connecting wall has basically the same advantages as the first selecting wall, i.e. it can squeeze the gasket and it can enhance the stiffness and rigidity of the plate to support high pressures. Furthermore, it can be used as a mounting means for the click-on tap.
- a click-on tap is positioned in the third section, wherein the click-on tap comprises a first portion reaching into a distance between crests and a second portion reaching under a crest. Such an embodiment secures the click-on tap in a direction perpendicular to a plane of the heat exchanger plate.
- the click-on tap comprises a third portion reaching in a space between a crest and the groove. This is possible, because the crests in the third section are shorter than the crests in the first section and/or the second section are.
- the third portion of the click-on tap can be used to secure the tap in a direction parallel to the plane of the heat exchanger plate.
- the third portion is positioned over the second connecting wall. It is thus held by the crests in the third section.
- the invention relates in a second aspect to a combination of the heat exchanger plate as described above and a gasket wherein the gasket has a volume that is larger than a volume of the groove.
- the volume of the gasket can slightly be larger than that of the groove, for example, by 20 to 25 %.
- Fig. 1 shows schematically a side view of a plate-type heat exchanger 1 having a number of heat exchanger plates 2 squeezed between a bottom plate 3 and a top plate 4. Openings 5, 6 are provided to form access of fluid to flow paths formed between the plates 2. In addition, there are two further openings 7, 8 which are visible in Fig. 2 only. The first openings 5, 6 can be used for a fluid flowing through the primary side of the heat exchanger 1 and the second openings 7, 8 can be used for a fluid flowing through the secondary side of the heat exchanger 1.
- Each heat exchanger plate 2 is provided with a gasket 9.
- the arrangement of gaskets is shown in Fig. 2 .
- the gasket 9 allows a flow from the first opening 5 to the second opening 6, i.e. through the primary side of the heat exchanger 1.
- the next heat exchanger plate 2 has a slightly different path of the sealing 9.
- the openings 5, 6 are sealed against the interior and (not visible) a flow path is established between the openings 7, 8, i.e. through the secondary side of the heat exchanger.
- Fig. 3 shows an edge area 10 of the heat exchanger plates 2. It is not necessary that the edge area 10 surrounds completely the heat exchanger plate 2. In most cases it is sufficient that the edge area extends along an edge connecting the openings 5, 6 or along an edge connecting the openings 7,8.
- the edge area 10 extends from an edge 11 towards the interior of the heat exchanger plate 2.
- the edge area 10 comprises a groove 12 running along the edge 11, i.e. substantially in parallel to the edge 11.

Abstract
Description
- The present invention relates to a heat exchanger plate comprising an edge, a groove running along the edge, and a corrugated area having crests and troughs between the groove and the edge, wherein crests run perpendicular to the edge.
- The invention is in particular used for a high-pressure gasket heat exchanger having a stack of such heat exchanger plates, wherein a gasket is arranged between two adjacent plates. The corrugated area along the edge forms contact points to the neighbouring plates and at the same time a supporting wall for the gasket.
- For mounting the heat exchanger the gasket has to be positioned in the groove and the heat exchanger plates have to be positioned one above the other. This can be complicated and requires some skill of a worker, since there is the risk that the gasket leaves the position in the groove when the heat exchanger plates are moved to the stack position.
- The object of the invention is to facilitate mounting of a plate-type heat exchanger.
- This object is solved with a heat exchanger plate as described at the outset, in that the corrugated area comprises at least two of three different sections, wherein in a first section adjacent crests are connected by a first connecting wall, in a second section at least one crest is flanked at both sides by a space between the crests that is open to the groove.
- In an embodiment the heat exchanger plate further comprises a third section that form a click-on tap position.
- The first connecting wall squeezes the gasket and keeps it in place by friction. The first connecting wall further assists in making the heat exchanger plate rigid and strong to support high-pressures. The second section comprises a space or a plurality of spaces which are open to the groove. Here the material of the compressed gasket is allowed to move into the open spaces assisting in keeping the gasket in position. The third section is provided to position a click-on tap in order to secure the gasket in the groove.
- In an embodiment of the invention the corrugated area comprises the first section, the second section, and the third section. In this case all three different possibilities are used.
- In an embodiment of the invention a bottom of the troughs is coplanar with a bottom of the groove. This is in particular useful in the region of the second section since the gasket has not to be moved over a step which is positive for the lifetime of the gasket and for the tightness of the heat exchanger.
- In an embodiment of the invention the first section comprises at least three crests. In other words, the first connecting wall extends at least over two troughs. The squeezing area of the gasket is quite large and the stiffness of the heat exchanger plate in this area is increased.
- In an embodiment of the invention in the second section the space between the crests is open to the edge. The space into which the gasket can move is preferably not limited in a direction towards the edge.
- In an embodiment of the invention in the third section the crests are shorter than in the first section or the second section. Accordingly, there remains a space between the crests in the third section and the groove which can be used for parts of the click-on tap.
- In an embodiment of the invention in the third section the crests are connected by a second connecting wall, wherein the second connecting wall has a height smaller than the height of the crests. The second connecting wall has basically the same advantages as the first selecting wall, i.e. it can squeeze the gasket and it can enhance the stiffness and rigidity of the plate to support high pressures. Furthermore, it can be used as a mounting means for the click-on tap.
- In an embodiment of the invention a click-on tap is positioned in the third section, wherein the click-on tap comprises a first portion reaching into a distance between crests and a second portion reaching under a crest. Such an embodiment secures the click-on tap in a direction perpendicular to a plane of the heat exchanger plate.
- In an embodiment of the invention the click-on tap comprises a third portion reaching in a space between a crest and the groove. This is possible, because the crests in the third section are shorter than the crests in the first section and/or the second section are. The third portion of the click-on tap can be used to secure the tap in a direction parallel to the plane of the heat exchanger plate.
- In an embodiment of the invention the third portion is positioned over the second connecting wall. It is thus held by the crests in the third section.
- The invention relates in a second aspect to a combination of the heat exchanger plate as described above and a gasket wherein the gasket has a volume that is larger than a volume of the groove.
- The volume of the gasket can slightly be larger than that of the groove, for example, by 20 to 25 %. When the gasket is mounted in the groove, it is squeezed, in particular by the first connecting wall, so that it is kept tight in the groove.
- A preferred embodiment of the invention will now be described in more detail with reference to the drawing, wherein:

A bottom of thetroughs 15 is coplanar with a bottom of thegroove 12, i.e. there is no step between the bottom of thetroughs 15 and thegroove 12 or such a step has a neglectable height. - The
corrugated area 13 at theedge 11 forms contact points to the neighbouringheat exchanger plates 2 and at the same time a supporting means for a gasket to be positioned in thegroove 12. - The
corrugated area 13 comprises at least two of threedifferent sections corrugated area 13 comprises all threedifferent sections - In the

crests 14 is open to thegroove 12. It can be totally open, i.e. it can be as well open to theedge 11. As can be seen inFig. 4 , the material of thecompressed gasket 9 is allowed to move into thetroughs 15 assisting in keeping thegasket 9 in position. - The number crests 14 of the
first section 16 connected by the connectingwall 19 defines a stiffens, or rigidness, of theheat exchanger plate 2 in theedge area 10, but at the same time makes an obstacle to the material of thecompressed gasket 9. A good number has been found to be in the range of 2-5crests 14, where the illustrated embodiments show three crests 14. - As seen in
fig. 3 , thecrests 14 in thesecond section 17 are isolated, meaning they are not connected to any connectingwall 19 at either side. They thus are flanked at both sides bytroughs 15 with spaces being totally open to theedge 11 allowingcompressed gasket 9 to move into thetoughs 15. - In the same manner, the number of
crests 14 if the second defines the area where thecompressed gasket 9 is allowed to move into thethroughs 15, but also reduces the stiffness, or rigidness, by reducing the number ofcrests 14 connected by connectingwall 19. However, in the same manner as for thefirst section 16, a good number ofcrests 14 in thesecond section 17 has been found to be in the range of 1-5. - In an embodiment the number of
