Abstract (en)

A plate heat exchanger includes a number of first heat exchange plates and a number of second heat exchange plates. The first heat exchange plate includes a first wave crest and a first wave trough. The second heat exchange plate includes a second wave crest and a second wave trough. Along a thickness direction, a maximum distance between the first wave crest and the first wave trough is h. In a direction of a shortest line connecting tops of adjacent first wave crests, a minimum connecting width of the first wave trough and the second wave crest is W<sub>1</sub>, and a minimum connecting width of the first wave crest and the second wave trough is W<sub>2</sub>. At least one of a ratio of W<sub>1</sub>/h and a ratio of W<sub>2</sub>/h is within a range of 0.25 to 2.5 to ensure the connection strength between adjacent heat exchange plates.
