ARC-SHAPED PLATE HEAT EXCHANGER

摘要

An arc-shaped plate heat exchanger, comprising a cylindrical housing (1) and a heat-exchanging plate assembly. The heat-exchanging plate assembly comprises two groups of arc-shaped heat-exchanging plates (2) symmetrically disposed at either side of the axis of the housing (1). In each group of the arc-shaped heat-exchanging plate (2), multiple arc-shaped heat-exchanging plates (2) are arranged from the center of the housing (1) outward and form isolating first fluid channels (201) and second fluid channels (202), the diameters of the plates increasing outward. During heat exchange, cold fluid (or hot fluid) enters the heat exchanger from a first fluid inlet (101) of the housing, and flows through straight channels of the arc-shaped heat-exchanging plates (2) to exit from a first fluid outlet (102), while the hot fluid (or cold fluid) enters the heat exchanger from a second fluid entrance (103) on the side wall of the housing (1), and flows through arc-shaped channels of the arc-shaped heat-exchanging plates (2) to exit from a second fluid outlet (104). Heat exchange between the cold fluid and the hot fluid is thus achieved.
