Claims (17)

1. A shell-and-plate heat exchanger (100) comprising a shell (20) and a plurality of heat transfer plates (10A, 10B) inside the shell (20), wherein said plates (10A, 10B) form fluidly connected first cavities (11) to create a first path (12) of the fluid flow for the first fluid flow, and the second cavity (21) is formed by the casing (20), in which the plates (10) are located, and a second fluid flow path (22) is created for the second fluid flow, separated from of the first fluid flow path (12) by the plates (10), wherein the first fluid flow path (12) passes through the inlet and outlet holes (13, 13') of the plates between adjacent plates (10A, 10B), and the second path (22) ) fluid flow passes through the second inlet and outlet holes (24, 24') of the casing (20), while the hole (13, 13') is located in the first distribution zone (33, 34) having the first part of the first distribution zone (33 ) on one side and the second part of the first distribution zone (34) on the second side, and between the holes (13, 13') there are central areas (32) of the transfer, and the corrugated pattern (30) of the first part of the first distribution zone (33) differs from corrugated pattern (30) of the second part of the first distribution zone (34). 2. Shell and plate heat exchanger (100) according to claim 1, in which the corrugations (30) in the first part of the first distribution zone (33) extend from the edge (14A) of the plate (10A, 10B) of the first part of the first distribution zone (33) towards the central area (32) heat transfer. 3. Shell and plate heat exchanger (100) according to claim 1 or 2, in which the corrugations (30) in the second part of the first distribution zone (34) extend from the edge (14A) of the plate (10A, 10B) of the first part of the first distribution zone (33) in direction of the central region (32) heat transfer. 4. A shell and plate heat exchanger (100) according to any one of the preceding claims, wherein a seal (44) is formed in the area between the central heat transfer region (32) and at least one of the openings (13, 13'). 5. A shell and plate heat exchanger (100) according to claim 4, wherein the seal (44) is formed as protrusions in the plates 10A, 10B formed in the section between the opening 13, 13' and the central heat transfer region 32. 6. Shell and plate heat exchanger (100) according to any of the preceding claims, wherein the first part of the first distribution zone (33) and the second part of the first distribution zone (34) are located on opposite sides of the opening (13) and mirror each other above the opening (13) corresponding to the line L from the first hole (13) to the second hole (13'), possibly through the centers of the holes (13, 13'). 7. Shell and plate heat exchanger (100) according to any one of the preceding claims, wherein the second opening (13') is located in the second distribution zone (33', 34') with the first part of the second distribution zone (33') on one side and the second part of the second distribution zone (34') on the second side, wherein the central transfer areas (32) extend between the first distribution zone (33, 34) and the second distribution zone (33', 34'), wherein the corrugated pattern (30) of the first part of the second distribution zone (33') differs from the corrugated pattern (30) of the second part of the second distribution zone (34'). 8. The shell and plate heat exchanger (100) according to claim 7, wherein the corrugations (30) in the first part of the second distribution zone (33') extend from the central heat transfer region (32) to the edge (14B) of the opening (13'). 9. A shell and plate heat exchanger (100) according to claim 7 or 8, wherein the corrugations (30) of the second part of the second distribution zone (34') extend from the central heat transfer region (32) to the edge (14B) of the opening (13'). 10. The shell and plate heat exchanger (100) according to claims 7 to 9, wherein the first part of the first distribution zone (33) and the first part of the second distribution zone (33') are both inclined in the same direction. 11. The shell and plate heat exchanger (100) according to claims 7 to 10, wherein the second part of the first distribution zone (34) and the second part of the second distribution zone (34') are both inclined in the same direction. 12. Shell and plate heat exchanger (100) according to claim 10, in which the second part of the first distribution zone (34) and the second part of the second distribution zone (34') are both inclined in the same direction, and the first part of the first distribution zone (33) and the first part of the second distribution zone (33') are both inclined in the first direction of inclination, wherein the second part of the first distribution zone (34) and the second part of the second distribution zone (34') are both inclined in the second direction of inclination, the first and second inclination directions being opposite to each other. 13.
