| 摘要 |
The invention relates to a spiral heat exchanger (1) including a spiral body (2) formed by at least one spiral sheet wounded to form the spiral body (2) forming at least a first spiral - shaped flow channel (20a) for a first medium and a second spiral- shaped flow channel (20b) for a second medium, wherein the spiral body (2) is enclosed by a substantially cylindrical shell (4) being provided with connecting elements (8a, 8b, 9a, 9b) communicating with the first flow channel (20a) and the second flow channel (20b), where the at least one spiral sheet comprises a corrugated heat transfer surface with corrugations for increasing the heat transfer and supports (6) for spacing the wounds of the at least one spiral sheet in the spiral body (2). |
