Definitions
- the present invention refers to a plate heat exchanger according to the preamble of claim 1 .
- a plate heat exchanger is disclosed in EP-B-1 456 593.
- the strength of the brazed plate heat exchanger is at least partly defined by the joining areas between adjacent heat exchanger plates.
- the distribution of this joining areas is important in order to be able to provide a high design pressure.
- the area along the centre line tend to include less joining areas than remaining parts of the heat transfer area due to the pattern of the ridges and valleys.
- the central area is therefore negatively affecting the total strength and the design pressure of the plate heat exchanger.
- This problem of less support in the area along the centre line is in particular accentuated in so called low theta pattern of ridges and valleys, where the angle of inclination of the ridges to the centre line is small.
- the object of the present invention is to provide a plate heat exchanger having a high design pressure, and more precisely a plate heat exchanger permitting a very high pressure of at least one of the media flowing therethrough. More specifically, the object is to improve the strength of the plate heat exchanger in an area along a central line of each heat exchanger plate.
- each connection part includes a projection extending along the centre line outwardly from the curved path and that projections of the connection parts form a respective central joining area at the centre line.
- each connection part has a concave side and a convex side, and has a width, measured between the concave side and the convex side and wherein the width has a maximum value at the centre line.
- the width of the connection part thus has its maximum at the projection. The width thus decreases with an increasing distance from the central line.
- the joining areas, including the central joining area are arranged along a plurality of transversal lines extending perpendicular to the centre line, wherein each central joining area is located on a respective one of the transversal lines.
- connection parts may be configured in such a manner that the joining areas, including the central joining area, are equidistantly, or substantially equidistantly, located along the transversal line.
- the distance between the central joining area and an adjacent joining area is equal, or substantially equal, to the distance along the transversal line between any two adjacent joining areas.
- the projection is delimited by two opposite side lines and a forward front line, wherein the side lines are substantially straight and converge towards each other towards the front line.
- the angle ⁇ of inclination is equal to or greater than 10° and less than 45°.
- the pattern formed by a V-configuration of the heat transfer area is thus a so called low theta pattern, characterized by a relatively low heat transfer and a relatively low flow resistance.
- the angle ⁇ of inclination is less than 40°, less than 35°, or even less than 30°.
- each heat exchanger plate has two distribution areas on a respective side of the heat transfer area, each distribution area surrounding two of the portholes.
- each distribution area may have ridges and valleys arranged in a V- configuration with a first part having a first extension line forming a positive angle ⁇ of inclination with the centre line at one side of the centre line, a second part having a second extension line forming a corresponding negative angle ⁇ of inclination with the centre line at the other side of the centre line, wherein the angle ⁇ of inclination is greater than 45°.
- the pattern formed by the V-configuration of the distribution areas is thus a so called high theta pattern, characterized by a relatively high heat transfer and a relatively high flow resistance. Such a high theta pattern contributes to an improved distribution of the media.
- said ridges and valleys, on one side of the heat exchanger plate extend between a primary level at a distance from the main extension plane and a secondary level at a distance from and on an opposite side of the main extension plane, and wherein each heat exchanger plate has a depth defined by the distance between the primary level and the secondary level and being equal to or less than 1 ,0 mm.
- a small depth of the heat exchanger plates improves the strength of the plate and the plate heat exchanger.
- the small depth of the heat exchanger plates permits a small distance between the ridges and valleys, on the heat transfer area, and thus a small distance between the joining areas between adjacent heat exchanger plates. Consequently, a small depth results in a small distance between the joining areas, and thus in a large number of such joining areas over the heat transfer area.
- the ridges are disposed at a distance from and extend in parallel with each other, wherein the distance between adjacent ridges on the heat transfer area is less than 4 mm.
- this distance may be approximately 3 mm.
- each heat exchanger plate before the forming, has a metal sheet thickness t, which lies in the range 0,2 ⁇ t ⁇ 0,4 mm.
- the braze material has a braze volume with respect to the heat transfer area of the plate heat exchanger, wherein the first interspaces and the second interspaces have an interspace volume with respect to the heat transfer area of the plate heat exchanger, and wherein the proportion of the braze volume to the interspace volume is at least 0,05.
- Such a relatively large volume of braze material enhances the strength of the joining between the heat exchanger plates, and thus the strength of the plate heat exchanger.
- the distribution areas comprise a first porthole, a second porthole, a third porthole, and a fourth porthole.
- every second heat exchanger plate 1 is rotated 180° in the main extension plane in the plate package.

- the heat transfer area 20 comprises a corrugation of ridges 27 and valleys 27' arranged in such a manner that the ridges 27 of one of the heat exchanger plates 1 abut the valleys 27' of an adjoining one of the heat exchanger plates 1 to form a plurality of joining areas 28 between a heat exchanger plate 1 and an adjacent heat exchanger plate 1 .
- the joining areas 28 are arranged along a plurality of transversal lines y extending perpendicular to the centre line x.
- the ridges 27 and valleys 27' extend along an extension line e forming an angle ⁇ of inclination with the centre line x, see Fig.

- the angle ⁇ of inclination may be less than 40°, less than 35°, or even less than 30° .
- the extension line e of each ridge 27 and valley 27' forms a positive angle ⁇ of inclination at one side of the centre line x and a corresponding negative angle ⁇ of inclination at the other side of the centre line x.
- the ridges 27 and valleys 27' also form joining areas 29 at the centre line x.

- the ridges 27 are disposed at a distance r form each other, and extend in parallel with each other and with the valleys 27'.
- the distance r between adjacent ridges 27, or between the respective central extension line e of adjacent ridges 27, may be less than 4 mm, or may be approximately 3 mm, or 3 mm, see Fig. 5.
- Each of the ridges 27 and valleys 27' thus has a V-shaped configuration with a first part 31 , for which the extension line e forms said positive angle ⁇ of inclination with the centre line x at one side of the centre line x, a second part 32, for which the extension line e forms said corresponding negative angle ⁇ of inclination with the centre line x at the other side of the centre line x, and a connection part 33 connecting the first part and the second part and extending along a curved path.
