| 摘要 |
A cryogenic rectification assembly has a heat exchanger panel with numerous parallel evaporation passages and liquefaction passages jointly surrounded by a heat transfer mantle. Especially within the heat transfer section, the specific heat transfer rate of two or more adjacent liquefaction and/or evaporation passages is different. There is a quasi-continual progressive difference between the specific heat transfer with respect to adjacent passages. The assembly has two, three, four or five different types of evaporation and/or liquefaction passages, each type having a different specific heat transfer rate. The evaporation and/or liquefaction passages are linked on their inlet side. The evaporation passage inlets and outlets are located on the same side of the heat exchanger panel. An Independent claim is included for a fluid evaporation process in which there is indirect exchange of heat with a heating medium.
