A device, including a heat exchanger plate and a plate package (2) of heat exchanger plates (1) which are provided beside each other to form a plate interspace between adjacent plates. The plate interspaces form, in an alternating order, first passages (3) for a first medium and second passages (4)
A device, including a heat exchanger plate and a plate package (2) of heat exchanger plates (1) which are provided beside each other to form a plate interspace between adjacent plates. The plate interspaces form, in an alternating order, first passages (3) for a first medium and second passages (4) for a second medium which cools the first medium. Each heat exchanger plate has at least two portholes forming a first inlet port channel and a first outlet port channel (7), which extend through the plate package to a first inlet and a first outlet, respectively, for the first medium to and from the first passages (3). The first outlet forms a gas outlet (31) for discharging a gaseous portion of the first medium and a liquid outlet (32) for discharge of liquid of the first medium. The liquid outlet (32) is separated from the gas outlet (31) to permit separate discharge of the liquid and gaseous portions.

What is claimed is: 1. A plate heat exchanger device comprising a plate package (2) formed by a plurality of heat exchanger plates (1, 1′, 1″), which are adjacent to each other so that a plate interspace (3,4) is formed between adjacent plates, which plate interspaces form first passa
What is claimed is: 1. A plate heat exchanger device comprising a plate package (2) formed by a plurality of heat exchanger plates (1, 1′, 1″), which are adjacent to each other so that a plate interspace (3,4) is formed between adjacent plates, which plate interspaces form first passages (3) for a first medium and second passages (4) for a second medium that is arranged to cool the first medium, wherein the first passages (3) and the second passages (4) are arranged beside each other in the plate package (2) in an alternating order, wherein the first passages (3) are separated from the second passages (4), wherein substantially each heat exchanger plate (1, 1′, 1″) has at least two portholes (16-19) forming a first inlet port channel (6) and a first outlet port channel (7), which extend through the plate package (2) to a first inlet (11) and to a first outlet (12), respectively, for the first medium to and from the first passages (3), wherein the first outlet (12) forms a gas outlet (31), which is arranged to permit discharge of substantially gas of the first medium, and a liquid outlet (32), which is arranged to permit discharge of substantially liquid of the first medium, wherein the liquid outlet (32) is separated from the gas outlet (31) for permitting separate discharge of said liquid and said gas, and wherein at least one of the two heat exchanger plates which delimits each first passage (3), is formed in such a way that a transition between the first passage (3) and the first outlet port channel (7) forms a throttle for the first medium flowing out into the first outlet port channel (7). 2. The device according to claim 1, wherein substantially each of the first passages (3) includes at least one liquid channel (41, 42) which extends along a substantial part of the first passage (3) in a direction towards the liquid outlet (32), and wherein at least one said liquid channel (41, 42) is arranged to convey liquid of the first medium to the liquid outlet (32). 3. The device according to claim 2, wherein said liquid channel (41, 42) is formed by a shaping of at least one of the two heat exchanger plates (1, 1′, 1″) that delimits each first passage (3). 4. The device according to claim 2, wherein said liquid channel (41, 42) extends immediately inside an outer edge of the first passage (3). 5. The device according to claim 2, wherein substantially each heat exchanger plate (1, 1′, 1″) includes a heat transfer area with a corrugation (26) including ridges and valleys, and wherein the corrugation (26) will catch liquid from the first medium. 6. The device according to claim 5, wherein the corrugation (26) of said ridges and valleys of one of the two heat exchanger plates (1, 1′, 1″) limiting each first passage (3) extends in a direction (a, b) towards said liquid channel (41, 42) and thus conveys the caught liquid to the liquid channel (41, 42). 7. The device according to claim 5, wherein the corrugation (26) of at least one of the two heat exchanger plates (1, 1′, 1″) limiting each first passage (3) includes a transversal ridge (44) projecting into the first passage (3) in the proximity of the first outlet (12) in such a way that liquid of the first medium is prevented from reaching the gas outlet (31). 8. The device according to claim 1, wherein the device is arranged to permit gas of the first medium to flow in a main first flow direction (c) from the first inlet port channel (6) to the first outlet port channel (7). 9. The device according to claim 8, wherein a transverse ridge (44) extends substantially transversally to the first flow direction (c). 10. The device according to claim 1, wherein the liquid outlet (32) is connectable to a liquid discharge conduit (36) which extends from the plate package (2). 11. The device according to claim 1, wherein the gas outlet (31) is connectable to a gas discharge conduit (35) which extends from the plate package (2). 12. The device according to claim 1, wherein the plate package (2) during normal use has an upper end and a lower end which is located beneath the upper end with regard to the direction of gravity, wherein the first inlet port channel (6) is located in the proximity of the upper end and the first outlet port channel (7) is located in the proximity of the lower end. 13. The device according to claim 12, wherein the gas outlet (31) has an outlet opening with a center point which during the normal use is located at a higher level than a center point of an outlet opening of the liquid outlet (32) with regard to the direction of gravity. 14. The device according to claim 1, wherein the gas outlet (31) has an outlet opening which has a larger flow area than an outlet opening of the liquid outlet (32). 15. The device according to claim 1, wherein said throttle is formed by an edge area (46) which extends around at least the gas outlet (31) and inwardly towards a center plane of the plate interspace. 16. The device according to claim 1, wherein each heat exchanger plate (1, 1′, 1″) has two further portholes (18, 19) forming a second inlet port channel (8) and a second outlet port channel (9), which extend through the plate package (2) and which form a second inlet (13) and a second outlet (14), respectively, for the second medium to and from the second passages (4). 17. The device according to claim 1, wherein the liquid outlet (32) is provided in or in the proximity of the gas outlet (31). 18. The device according to claim 1, wherein the first outlet (12) includes at least a further heat exchanger plate (1a), which is provided at the plate package for forming a further plate interspace to convey said gas from the first outlet port channel (7) to the gas outlet (31). 19. The device according to claim 18, wherein the further heat exchanger plate is provided at the plate package in such a way that it forms a part of the plate package. 20. The device according to claim 1, wherein the first outlet (12) includes a plurality of further heat exchanger plates, which are provided beside each other and at the plate package for forming further plate interspaces (3a, 3b), and wherein at least every second one (3b) of said further plate interspaces are arranged to convey said gas from the first outlet port channel (7) to the gas outlet (31). 21. The device according to claim 20, wherein said further heat exchanger plates are provided at the plate package in such a way that they form a part of the plate package. 22. The device according to claim 21, wherein every second (3a) of said further plate interspaces are arranged to form a part of the first inlet (11) and to convey the first medium to the first inlet port channel (6) in heat exchanging contact with said gas.
