Description

HEAT TRANSFER PLATE FOR PLATE HEAT EXCHANGER AND PLATE HEAT EXCHANGER WITH THE SAME
TECHNICAL FIELD [0001] Embodiments of the present disclosure relates to a heat transfer plate for a plate heat exchanger and a plate heat exchanger.
BACKGROUND [0002] FIG. 1 shows a typical construction of a plate heat exchanger 100'. The plate heat exchanger 100' comprises a plurality of heat transfer plate 10' stacked on top of each other. The heat transfer plates 10' are formed with patterns such that flow paths are formed between each set of neighbouring heat transfer plates 10'. Openings 21 and 22 are formed in the heat transfer plates 10' to form inlets and outlets for fluids to these flow paths. Gaskets 60 are positioned between the heat transfer plates 10' in gasket grooves 12 formed in the heat transfer plates. The gasket is arranged at an edge portion of the heat transfer plate to seal the flow paths and at an area around the openings to seal pairs of the openings, such that only two of them have flow access to the flow path formed at one side of the heat transfer plate, while the other two is sealed therefrom.
[0003] FIG. 2 shows that the heat exchanger plates 10' are stacked and positioned between relatively thick and rigid top and bottom plates 51 and 52. Tension shown by arrows is then applied to the heat exchanger plates 10' to keep them close together and to squeeze the gaskets 60 slightly such that stable and fluid tight flow paths are formed. This tension typically is implemented through bolts (not shown) extending from the top plate 51 to the bottom plate 52.
[0004] The upper figure in FIG. 2 shows the state of the heat exchanger plates 10' before the tension is applied to them, while the lower figure in FIG. 2 shows a frequently experienced problem that this tension tends to prolong the heat exchanger plates 10', such as by several millimetres.

DETAILED DESCRIPTION [0033] Referring to FIGS. 3 and 4, a plate heat exchanger 100 according to an embodiment of the present disclosure is shown. The plate heat exchanger 100 comprises: a plurality of heat transfer plates 10 which are stacked on top of each other; and gaskets 60 (referring to FIG. 1) disposed in gasket grooves 12 of some of the plurality of heat transfer plates 10. The heat transfer plates 10 are formed with patterns such that flow paths are formed between each set of neighbouring heat transfer plates 10. Openings 21 and 22 are formed in the heat transfer plates 10 to form inlets and outlets for fluids to these flow paths.
[0034] Referring to FIGS. 3 to 8B, the heat transfer plate 10 comprises: a plate body 11 and a ridge 20. The plate body 11 has a gasket groove 12 with a groove wall 13, 14. The groove wall 13, 14 has a groove wall body 130, 140. The ridge 20 is disposed on the groove wall body 130, 140 of a segment 120 of the gasket groove 12 in a length direction of the gasket groove 12. The ridge 20 may be continuous. In addition, the ridge 20 may extend essentially parallel to an edge 121 of the plate body 11 or extends essentially parallel to a length direction of the plate body 11 (FIG. 4). The heat transfer plate 10 may be formed of a metal plate by pressing.
[0035] Referring to FIGS. 4 to 8B, the ridge 20 is projected from the groove wall body 130, 140 in a direction from an outside of the gasket groove 12 toward an inside of the gasket groove 12. Alternatively, the ridge 20 may also be projected from the groove wall body 130, 140 in a direction from an inside of the gasket groove 12 toward an outside of the gasket groove 12.
[0036] Referring to FIGS. 4 to 8B, in some embodiments, the groove wall 13, 14 comprises two side walls 13 and a bottom wall 14. Each of the two side walls 13 has a side wall body 130, the bottom wall 14 has a bottom wall body 140, and the groove wall body 130, 140 comprises the side wall bodes 130 and the bottom wall body 140. The ridge 20 is disposed on at least one of the bottom wall body 140 and the side wall bodies 130 of the segment 120 of the gasket groove 12 in
Page 5 of 8
DK 2017 00670 A1 the length direction of the gasket groove 12. As shown in FIGS. 4 to 8B, the ridge 20 is projected from the at least one of the bottom wall body 140 and the side wall bodies 130 in a direction from an outside of the gasket groove 12 toward an inside of the gasket groove 12. Alternatively, the ridge 20 may also be projected from the at least one of the bottom wall body 140 and the side wall bodies 130 in a direction from an inside of the gasket groove 12 toward an outside of the gasket groove 12. [0037] Referring to FIGS. 4, 8A and 8B, FIG. 8A shows the cross section of a part of the gasket groove and its groove wall where the encircled part illustrates the ridge formed in the groove wall of the gasket groove. The heat transfer plate 10 further comprises: a heat exchanging area 101 surrounded by the gasket groove 12. In an embodiment, the ridge 20 is disposed on one of the side wall bodies 130 facing towards the heat exchanging area 101. In the present embodiment, corrugations 102 in the heat exchanging area 101 are integrated with the ridge 20, and accordingly are deformed slightly as indicated by the encircled part in FIG. 8B. Alternatively, referring to FIGS. 5A and 5B, the ridge 20 is disposed on one of the side wall bodies 130 facing away from the heat exchanging area 101. In some embodiments, referring to FIGS. 5A, 5B, 8A and 8B, the ridge 20 is disposed on at least one of the side wall bodies 130, and is closer to the bottom wall body 140 than to the plate body 11. Alternatively, the ridge 20 may be closer to the plate body 11 than to the bottom wall body 140, or the ridge 20 may also be disposed on a middle portion of at least one of the side wall bodies 130 in a width direction of the side wall body 130. The ridge 20 constitutes a barrier for protecting the heat exchanging area 101 as well as the groove wall 13, 14. Referring to FIGS. 5B, 6B, and 8B, in the heat exchanging area 101, the heat transfer plates 10 are formed with the chevron-shaped corrugations 102. However, the present invention is not limited to any structure formed in the heat exchanging area. For example, in the heat exchanging area 101, the heat transfer plates 10 may also be formed with other patterns such as bulges and hollows. The heat transfer plates 10 are reinforced by the ridge 20 to have sufficient rigidity, thereby preventing the elongation of the heat transfer plates 10 at least under the action of the tension.
Page 6 of 8
DK 2017 00670 A1
Although the figures show that the ridge 20 is disposed on one of the side wall bodies 130, the ridge may be formed in either or both of the side wall bodies 130. [0038] Referring to FIGS. 6A and 6B, in another embodiment, the ridge 20 is disposed on a middle portion of the bottom wall body 140 in a width direction of the bottom wall body 140. Alternatively, referring to FIG. 7, the ridge 20 is disposed on a side of the bottom wall body 140 facing towards the heat exchanging area 101 in a width direction of the bottom wall body 140, or the ridge 20 may also be disposed on a side of the bottom wall body 140 facing away from the heat exchanging area 101 in the width direction of the bottom wall body 140.
[0039] Referring to FIG. 4, in some embodiments, the segment 120 of the gasket groove 12 provided with the ridge 20 extends essentially parallel to an edge 121 of the plate body 11 or extends essentially parallel to a length direction of the plate body 11. The segment 120 of the gasket groove 12 provided with the ridge 20 may have a length essentially equal to a length of an entire straight portion of the gasket groove 12. The straight portion of the gasket groove 12 is essentially parallel to the edge 121 of the plate body 11 or the length direction of the plate body 11.
[0040] Although in the embodiments, only one ridge 20 is formed on the groove wall body 130, 140, a plurality of ridge 20 may be formed on the groove wall body 130, 140. In addition, the figures shows that one of the bottom wall body 140 and the side wall bodies 130 is formed with the ridge 20, but all of the bottom wall body 140 and the side wall bodies 130, the bottom wall body 140 and one of the side wall bodies 130, or all of the side wall bodies 130 may be formed with the ridges 20.
[0041] While the figures shows that the gasket groove 12 has a U-shaped cross section, the cross section of the gasket groove 12 may have any other appropriate shapes, such as a V shape, and a semicircular shape.
[0042] With the heat transfer plate 10 and the plate heat exchanger 100 according to the embodiments of the present disclosure, the prolongation of the heat transfer plates 10 occurring when tension is applied to the heat exchanger plates can be at least partly alleviated.
