Abstract
In a heat exchanger comprising a plurality of first heat-transfer elements (A) for a fluid of higher temperature and second heat-transfer elements (B) for a fluid of lower temperature joined alternately and adjacently and a suitable number of appropriately shaped fins disposed within said elements and wherein the heat exchange is performed between the fluid (a) of higher temperature and the fluid (b) of lower temperature and at least the fluid (a) is changed in phase during the heat exchange, the improvement of providing such a heat exchanger with the ability to rectify the condensate from the fluid (a) and to recover the rectified liquid, wherein the fins in the lower part of the element (A) are so arranged that the fluid (a) entering from a port into the element (A) flows upwards smoothly with contact with the liquid condensed from the fluid (a) at the upper part of the element (A), which flows down through the heat exchanger. The condensed liquid flows down through the fins and is taken out from a port provided at the lowest part of the element (A). Accordingly, condensation of a gaseous fluid and rectification of the resulting condensate are both performed with high efficiency in the same apparatus.
