Description

A heat exchanger plate, and a plate heat exchanger TECHNICAL FIELD OF THE INVENTION The present invention refers to a heat exchanger plate for a plate heat exchanger, the heat exchanger plate comprising a heat exchanger area extending in parallel with an extension plane, wherein the heat exchanger area is delimited by at least three sides which are connected to each other by at least three curved corners, a longitudinal central axis extending in parallel with the extension plane through at least one of the sides, a plurality of portholes extending through the heat exchanger area, and an edge flange extending outside and around the heat exchanger area along the sides, wherein the edge flange is inclined in relation to the extension plane The invention also refers to a plate heat exchanger comprising a plurality of heat exchanger plates.
BACKGROUND OF THE INVENTION AND PRIOR ART A heat exchanger plate of this kind is disclosed in US-8,061,416. When pressing such heat exchanger plates, plate holders and a forming ring are used to hold the raw plate and form the flange of the heat exchanger plate during the pressing operation. However, due to the excess of material from the radius reduction of the flange at the corners, the material the edge flange at the curved corners is easily wrinkled.
SUMMARY OF THE INVENTION The object of the present invention is to remedy the problems discussed above. In particular, it is aimed at a prevent wrinkling of the edge flange at the curved corners of the heat exchanger plate.
This object is achieved by the heat exchanger plate initially defined, which is characterized in that the edge flange comprises a corrugation of ridges and valleys provided along the curved corners, wherein the ridges and valleys of the flange corrugation extend along a direction away from extension plane of the heat exchanger area.
The flange corrugation provides a better handling of excess material of the edge flange along the curved corners. The flange corrugation forms a controlled folding of the edge flange. Thus, undesired folding or wrinkling, and portions of thicker material as a result of the pressing operation can be avoided. The pressing operation may be performed without any plate holders holding the heat exchanger plate during the pressing operation.
The flange corrugation also contributes to an improved locking of the heat exchanger plates when they are stacked on each other. The position of the heat exchanger plates relative to each other is more determined than if the edge flange at the curved corners have no corrugation.
Furthermore, the flange corrugation may provide the inclined edge flange with an elasticity at the curved corners, which may facilitate the achievement of a tight abutment against adjacent heat exchanger plates. The flange corrugation may also contribute to an improved resistance against thermal fatigue and an improved burst pressure resistance at the curved corners.
In addition, the flange corrugation of the edge flange at the curved corners may cause a turbulent flow around ports, which impedes freezing in these areas.
According to the invention, the ridges and valleys of the flange corrugation extend along a direction away from extension plane of the heat exchanger area. Said direction may cross the extension plane. The flange corrugation of ridges and valleys extending in said direction may absorb a significant amount of excessive material of the edge flange at the curved corners.
According to a further embodiment of the invention, the edge flange has a root end at the heat exchanger area, and an outer end, wherein the edge flange is inclined from the root end to the outer end. Advantageously, the edge flange may be inclined with an inclination angle that is constant from the root end to the outer end.
According to a further embodiment of the invention, the ridges and the valleys of the flange corrugation extend from the root end to the outer end along the curved corners.
According to a further embodiment of the invention, the edge flange comprises a transition zone, which extends between the heat exchanger area and the flange corrugation, wherein the flange corrugation extends from the transition zone to the outer end. Thus, the transition zone may have no corrugation or provide an evenly curved surface of the edge flange along the curved corners between the heat exchanger area and the flange corrugation.
According to a further embodiment of the invention, the heat exchanger area comprises a heat transfer corrugation. Such heat transfer corrugation may improve the heat transfer between the media circulation through the plate heat exchanger.
According to a further embodiment of the invention, the heat transfer corrugation comprises ridges and valleys. The heat transfer corrugation may have various geometrical shapes, and may, instead of ridges and valleys, comprise other kinds of corrugations, such as dimples or similar spot shaped depressions and/or protrusions.
According to a further embodiment of the invention, the ridges and valleys of the heat transfer corrugation extend along a direction crossing the longitudinal central axis. For instance, the ridges and valleys may extend along one direction from one of the sides to an opposite one of the sides, or the ridges and valleys may extend along two directions which meet at the longitudinal central axis, thus forming a fishbone pattern.
According to a further embodiment of the invention, the at least three sides comprise two opposite long sides and two opposite short sides. The long sides and the opposite sides may be straight or substantially straight.
According to a further embodiment of the invention, the flange corrugation is also provided on the edge flange along the long sides, or along the whole length of the long sides.
According to a further embodiment of the invention, the flange corrugation is also provided on the edge flange along the short sides.
The object is also achieved by the plate heat exchanger initially defined, comprising a plurality of heat exchanger plates as defined above.
The plate heat exchanger according to the invention will take advantage of the technical advantages and properties of the heat exchanger plates explained above. Since excessive material and wrinkling of the edge flange at the curved corners may be avoided, the heat exchanger plates will fit better to each other when the plate heat exchanger is assembled. Since the flange corrugation along the curved corners is elastic and flexible, the heat exchanger plates are more flexible and thus easily stacked onto each other when the plate heat exchanger is assembled.
According to a further embodiment of the invention, the heat exchanger plates are permanently joined to each other. Such permanent joining may be obtained through bonding, brazing, welding, gluing etc.
According to a further embodiment of the invention, the ridges of the flange corrugation of one of the heat exchanger plates adjoin, or abut, the ridges of the flange corrugation of the heat exchanger plates provided adjacent to said one heat exchanger plate. More precisely, the whole surface of the edge flange of one heat exchanger plate may thus adjoin the whole surface of the edge flange of the adjacent heat exchanger plate or plates. This contributes to the improved stiffness and improved strength of the plate heat exchanger according to the invention.

A longitudinal central axis x extends in parallel with the extension plane p through the short sides 6. As can be seen in Fig 4, the longitudinal central axis x may be parallel with the long sides 5.
The heat exchanger plate 1 also comprises an edge flange 8, which extends outside and around the heat exchanger area 4 along the sides, i.e. in the embodiments disclosed along the long sides 5, the short sides 6 and the corners 7. The edge flange 8 is inclined in relation to the extension plane p, with an angle a of inclination, see Fig 5.
The heat exchanger plate 1 also comprises four portholes 9, which extend through the heat exchanger area 4.
The heat exchanger area 4 comprises a heat transfer corrugation 10. In the embodiments disclosed, the heat transfer corrugation comprises or consists of ridges 11 and valleys 12, see Fig 4.
The heat transfer corrugation 10 may form various patterns, for instance a diagonal pattern, a fishbone pattern, etc. as is known in the art of plate heat exchangers. In the embodiments disclosed, the heat transfer corrugation 10 forms a fishbone pattern of the ridges 11 and the valleys 12 extending along a direction crossing the longitudinal central axis x. The ridges 11 and valleys 12 form a positive angle of inclination on one side of the longitudinal central axis x and a corresponding negative angle of inclination on the other of the longitudinal central axis x.
Other geometrical shapes of the heat transfer corrugation 10 are also possible, for instance a corrugation of dimples or other spot shaped depressions and/or protrusions.
As can be seen in Fig 4, the ridges 11 and valleys 12 of the heat transfer corrugation 10 extend to the long sides 5.
The edge flange 8 of the heat exchanger plate 1 comprises a flange corrugation 20 of ridges 21 and valleys 22. The flange corrugation 20 is provided on the edge flange 8 along the curved corners 7 as can be seen in Fig 4.

The heat transfer corrugation 10 extends to the root end 25 of the edge flange 8, as can be seen in Fig 4.
As mentioned above, the plate heat exchanger is a brazed plate heat exchanger. The individual heat exchanger plates 1 are compression molded to obtain the shape disclosed and described herein. The heat exchanger plates 1 are the stacked onto each other with a sheet of braze material between each heat exchanger plate 1. Moreover, the heat exchanger plates 1 are stacked onto each other so that the ridges 21 of the flange corrugation 20 of one of the heat exchanger plates 1 adjoin the ridges 21 of the flange corrugation 20 of the heat exchanger plates 1 provided adjacent to said one heat exchanger plate 1. In the same way, the valleys 22 of the flange corrugation 20 of one of the heat exchanger plates 1 adjoin the valleys 22 of the flange corrugation 20 of the heat exchanger plates 1 provided adjacent to said one heat exchanger plate 1. The whole surface of the edge flange 8 of one heat exchanger plates 1 may thus adjoin the whole surface of the edge flange 8 of the adjacent heat exchanger plate 1 or plates 1.
In the plate heat exchanger with heat exchanger plates 1 according to the embodiments disclosed, the portholes 9 of the heat exchanger plates 1 may form a first inlet port 31 for the first fluid to the first plate interspaces 2, a first outlet port 32 for the first fluid from the first plate interspaces 2, a second inlet port 33 for the second fluid to the second plate interspaces 3, and a second outlet port 34 for the second fluid from the second plate interspaces 3, see Fig 1. Each of the ports 31-34 may comprise a connection pipe, as can be seen in Figs 2 and 3.
The outermost heat exchanger plate 1, at which the ports 31-34 are provided, may form frame plate, and the opposite outermost heat exchanger plate 1 may form a pressure plate.
The stack of heat exchanger plates 1 is then brazed by being heated to a suitable temperature. The stack is held together during the heating and following cooling by a deadweight provided on top of the stack.
Fig 6 discloses a heat exchanger plate 1 according to a second embodiment, which differs from the first embodiment only in that, the edge flange 8 comprises a transition zone 28, which extends between the heat transfer corrugation 10 and the flange corrugation 20. The transition zone 28 starts at the root end 25 and extends towards the outer end 26. The flange corrugation 20 thus extends from the transition zone 28 to the outer end 26 of the edge flange 8 along the curved corners 7.
The invention is not limited to the embodiments disclosed, but may be varied and modified within the scope of the following claims.
The invention is applicable to all permanently joined plate heat exchangers, especially brazed plate heat exchanger, not only those for two fluids, but also plate heat exchangers for more than two fluids, for instance three fluids.
