Based on the previous fundamental investigations the new type heat exchangers with heat transfer surface of waving plates were designed. The press dies for waving plates could be easily manufactured. One type of them had the two dimensional flow channels partitioned with the progressive waves, and it showed, as expected, a larger heat transfer coefficient than the conventional one. The another type had the three dimensional flow channels formed by arranging the plates with the oblique wave patterns. This type is strong against the high pressure because the plates contact each other at many points of wave peaks of them. The most suitable configuration of the heat transfer plate was determined based on the results of the investigation on such factors as the distance of waves, and the oblique angle of the wave Pattern.
