Description

Heat transfer plate for a plate heat exchanger and plate heat exchanger with a heat transfer plate
Technical Field
Embodiments of the present disclosure relate to a plate heat exchanger and a heat transfer plate for a plate heat exchanger.
Background
Fig. 1 shows a typical structure of a plate heat exchanger 100'. The plate heat exchanger 100 'comprises a plurality of heat transfer plates 10' stacked on top of each other. The heat transfer plates 10 'are patterned such that flow paths are formed between each set of adjacent heat transfer plates 10'. Openings 21 and 22 are formed in the heat transfer plate 10' to form inlet and outlet ports for fluid flow to these flow paths. The gasket 60 is positioned between the heat transfer plates 10' in a gasket groove 12 formed in the heat transfer plates. Gaskets are arranged at edge portions of the heat transfer plates to seal the flow paths, and at areas around the openings to seal the pairs of openings, such that only two of them have flow channels to the flow paths formed at one side of the heat transfer plates, while the other two are sealed therefrom.
Fig. 2 shows that the heat exchanger plates 10' are stacked and positioned between a relatively thick and rigid top plate 51 and a bottom plate 52. A tension force, indicated by arrows, is then applied to the heat exchanger plates 10' to bring them closer together and slightly compress the gasket 60, thereby forming a stable and fluid-tight flow path. This tension is typically achieved by bolts (not shown) extending from the top plate 51 to the bottom plate 52.
The upper diagram in fig. 2 shows the state of the heat exchanger plate 10 ' before a tension is applied to the heat exchanger plate 10 ', while the lower diagram in fig. 2 shows a problem often encountered, i.e. that the tension tends to elongate the heat exchanger plate 10 ', for example by a few millimetres.

The ridge 20 may be continuous. In addition, the ridge 20 may extend substantially parallel to the edge 121 of the plate body 11, or substantially parallel to the length direction of the plate body 11 (fig. 4). The heat transfer plate 10 may be formed of a metal plate by pressing.
Referring to fig. 4 to 8B, the ridges 20 protrude from the groove walls 130, 140 in a direction from the outside of the gasket groove 12 toward the inside of the gasket groove 12. Alternatively, the ridges 20 may also protrude from the groove walls 130, 140 in a direction from the inside of the gasket groove 12 toward the outside of the gasket groove 12.
Referring to fig. 4-8B, in some embodiments, the slot walls 13, 14 include 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 slot wall bodies 130, 140 include the side wall body 130 and the bottom wall body 140. The ridge 20 is provided on at least one of the bottom wall body 140 and the side wall body 130 of the section 120 of the gasket groove 12 in the length direction of the gasket groove 12.
