    Detailed Description of the Invention
  • The present invention is explained further below in conjunction with the drawings and particular embodiments.
  • Referring to Figs. 1 - 9C, a plate heat exchanger according to an embodiment of the present invention comprises: multiple heat exchange plates 10; and a heat exchange space formed between adjacent heat exchange plates 10 of the multiple heat exchange plates 10. The plate heat exchanger further comprises a cover plate, etc.
  • Referring to Figs. 1 - 9C, a heat exchange plate 10 for a plate heat exchanger according to an embodiment of the present invention comprises: a heat exchange plate body 11; and a ring-shaped flange 3 projecting obliquely from an edge of the heat exchange plate body 11, the flange 3 having a protrusion 5 which has a reinforcing action. The flange 3 of this heat exchange plate 10 is in a lap joint with a flange 3 of an adjacent heat exchange plate 10. Through the reinforcing action of the protrusion 5, the strength and rigidity of the flange 3 can be increased.
  • The terms "ring-shaped" and "ring-like" mentioned herein refer to a shape in which a head end and a tail end are connected to form a closed contour, and do not refer exclusively to a circular shape. For example, when viewed in a direction perpendicular to the heat exchange plate, the overall shape of the flange 3 depends on the shape of the heat exchange plate 10, and for example is a rectangular ring. The same principle applies to the term "ring-like belt" below.
  • Referring to Figs. 1 - 9C, in some embodiments of the present invention, the flange 3 has an inner side facing the center of the heat exchange plate 10 and an outer side remote from the center of the heat exchange plate 10, and the protrusion 5 protrudes toward the inner side or outer side of the ring-shaped flange 3.
  • Referring to Figs. 1 - 9C, in some embodiments, the flange 3 comprises: a first ring-like belt 31 adjoining the heat exchange plate body 11; and a second ring-like belt 32 which adjoins the first ring-like belt 31 at a side of the first ring-like belt 31 that is remote from the heat exchange plate body 11, at least a part of the second ring-like belt 32 protruding relative to the first ring-like belt 31 to form the protrusion 5.
  • Referring to Figs. 4 - 5, Figs. 6A - 6C and Figs. 9A - 9C, in some embodiments of the present invention, the second ring-like belt 32 comprises the protrusion 5. Referring to Figs. 6A - 6C, according to some examples of the present invention, the protrusion 5 is a ring-shaped protrusion 5 along the entire second ring-like belt 32, and thereby forms a step structure. In this case, when multiple heat exchange plates 10 are welded together, the first ring-like belts 31 of adjacent heat exchange plates 10 are in contact with each other, and the second ring-like belts 32 of adjacent heat exchange plates 10 are in contact with each other. Alternatively, referring to Figs. 9A - 9C, according to some other examples of the present invention, the protrusion 5 is multiple protrusions 5 arranged at intervals along the second ring-like belt 32.
  • Referring to Figs. 3 - 5, in some embodiments, the flange 3 comprises: a first ring-like belt 31 adjoining the heat exchange plate body 11; a second ring-like belt 32 which adjoins the first ring-like belt 31 at a side of the first ring-like belt 31 that is remote from the heat exchange plate body 11; and a third ring-like belt 33 which adjoins the second ring-like belt 32 at a side of the second ring-like belt 32 that is remote from the first ring-like belt 31, at least a part of at least one of the second ring-like belt 32 and the third ring-like belt 33 protruding relative to the first ring-like belt 31 to form the protrusion 5. According to some examples of the present invention, the second ring-like belt 32 protrudes relative to the first ring-like belt 31 to form a ring-shaped protrusion 5. In the example shown in Fig. 3 (not forming part of the invention), the flange 3 has an inner side facing the center of the heat exchange plate 10 and an outer side remote from the center of the heat exchange plate 10, the second ring-like belt 32 protrudes toward the outer side of the ring-shaped flange 3 relative to the first ring-like belt 31, the third ring-like belt 33 protrudes toward the outer side of the ring-shaped flange 3 relative to the first ring-like belt 31, to form a ring-shaped protrusion 5, and the amount by which the second ring-like belt 32 protrudes relative to the first ring-like belt 31 is less than the amount by which the third ring-like belt 33 protrudes relative to the first ring-like belt 31; multiple steps are thereby formed, for example multiple ring-shaped steps. In the example shown in Fig. 4, the second ring-like belt 32 of the lower heat exchange plate 10 protrudes toward the outer side of the flange 3 relative to the first ring-like belt, and the third ring-like belt 33 is substantially flush with the first ring-like belt 31. In the example shown in Fig. 5, the second ring-like belts 32 of the two heat exchange plates 10 protrude toward the outer side and the inner side of the flange 3, respectively, relative to the first ring-like belts, and the third ring-like belts 33 of the two heat exchange plates 10 are both substantially flush with the first ring-like belts 31.
  • Referring to Figs. 4 - 9C, in some embodiments, the flange 3 comprises a ring-like flange body 30, the flange body 30 having a belt shape; the protrusion 5 protrudes from the flange body 30, and as shown in Figs. 6A - 6C, the protrusion 5 is a ring-shaped protrusion 5 extending along the entire ring-like flange body 30. According to some examples of the present invention, the protrusion 5 is substantially parallel to the flange body 30.
  • Referring to Figs. 4 - 9C, in some embodiments, the flange 3 comprises a ring-like flange body 30, the flange body 30 having a belt shape; the protrusion 5 protrudes from the flange body 30, and as shown in Figs. 7A - 9C, the protrusion 5 is multiple protrusions 5 arranged at intervals along the ring-like flange body 30.
  • Referring to Figs. 6A - 9C, in some embodiments, at least one of multiple protrusions 5 has a linear shape or a strip-like shape. In the examples shown in Figs. 7A - 8C, at least one of multiple protrusions 5 crosses the ring-like flange body 30. For example, at least one of multiple protrusions 5 is substantially perpendicular to the ring-like flange body 30. According to some examples of the present invention, at least one of multiple protrusions 5 extends over the entire width of the belt-shaped flange body 30.
  • Referring to Figs. 8A - 8C, in some embodiments of the present invention, the multiple protrusions 5 have a linear shape or a strip-like shape, a first protrusion 5A of the multiple protrusions 5 is substantially parallel to a part of the ring-like flange body 30 on which the first protrusion 5A is arranged, and a second protrusion 5B of the multiple protrusions 5 is substantially perpendicular to a part of the ring-like flange body 30 on which the second protrusion 5B is arranged. For example, referring to Fig. 8B, when viewed in a direction perpendicular to the heat exchange plate body 11, the first protrusion 5A and the second protrusion 5B extend in substantially the same direction.
  • Referring to Figs. 1 - 9C, in some embodiments, the height of the protrusion 5 is in the range of 0.05 mm - 0.5 mm; for example, the height of the protrusion 5 is in the range of 0.05 mm - 0.2 mm. It must be noted that the protrusion 5 has been drawn in an exaggerated manner in Figs. 2 - 5, but as stated above, the protrusion 5 is actually very small, and takes the form of an indentation, so that the thickness thereof is very difficult to see at a larger scale, for example in Figs. 6A and 6C.
  • Referring to Figs. 1 - 9C, a plate heat exchanger according to an embodiment comprises: multiple heat exchange plates 10, at least one of the multiple heat exchange plates 10 being the heat exchange plate 10 described above.
  • Referring to Figs. 2 - 5, according to an embodiment, the multiple heat exchange plates 10 comprise a first heat exchange plate 10 (e.g. the upper heat exchange plate 10 of the two heat exchange plates 10 in Figs. 2, 3, 4 and 5) and a second heat exchange plate 10 (e.g. the lower heat exchange plate 10 of the two heat exchange plates 10 in Figs. 2, 3, 4 and 5) which are adjacent to each other. A protrusion 5 of a flange 3 of the first heat exchange plate 10 protrudes toward a side remote from a flange 3 of the second heat exchange plate 10, and a gap 9 is formed between the protrusion 5 of the flange 3 of the first heat exchange plate 10 and the flange 3 of the second heat exchange plate 10, the gap 9 being filled with solder for soldering the plate heat exchanger, in order to solder together the protrusion 5 of the flange 3 of the first heat exchange plate 10 and the flange 3 of the second heat exchange plate 10. The reinforcing effect of the protrusion 5 on the flange 3 can thereby be further improved for example.
  • According to an embodiment of the present invention, by providing the protrusion 5 in the flange 3, it is possible to prevent warping of the heat exchange plate, improve the quality of heat exchanger brazing, and facilitate heat exchanger assembly.
  • According to an embodiment of the present invention, by providing the protrusion 5 in the flange 3, it is possible to prevent a heat exchange region of the heat exchange plate 10 from being affected, thus preventing the heat exchange performance of the heat exchanger from being affected.
  • According to an embodiment of the present invention, by providing the protrusion 5 in the flange 3, it is possible to prevent elastic rebound after forming of the heat exchange plate 10, thus making the structure of the heat exchange plate more stable.
  • According to an embodiment of the present invention, when the protrusion 5 is provided in the flange 3, the protrusion can be formed more easily, and the difficulty of manufacture of the heat exchanger is thereby reduced.
