PLATE HEAT EXCHANGER USED AS EVAPORATOR OR CONDENSER

WIPO Patent Application WO/2010/013608

A1

In a plate heat exchanger, a plurality of heat transfer plates (12) are stacked in such a manner that a plurality of first heat exchange chambers (15) and a plurality of second heat exchange chambers are alternately formed between the heat transfer plates, and steam is generated or condensed in the first heat exchange chambers.  An evaporation capacity when the steam is generated or a condensing capacity when the steam is condensed is increased in the heat exchanger.  A large number of first raised parts (30) of a truncated cone shape projecting into the first heat exchange chamber (15) and a large number of second raised parts (31) of a truncated cone shape projecting into the second heat exchange chamber (16) are provided on each heat transfer plate (12).  The first raised parts (30) are brought into contact with each other in the first heat exchange chamber (15), and the second raised parts (31) are brought into contact with each other in the second heat exchange chamber (16).
