    摘要： Disclosed is a plate heat exchanger. The plate heat exchanger comprises a plurality of heat transfer plates, the plurality of heat transfer plates comprising: a first heat transfer plate, comprising protrusions protruding upward, the protrusions having a top; and a second heat transfer plate stacked on the first heat transfer plate, the second heat transfer plate comprising recesses recessed downward, the recesses having a bottom. The tops of the protrusions have a concave portion which is sunken downward, and at least part of the bottoms of the recesses of the second heat transfer plate is disposed in the concave portion of the tops of the protrusions of the first heat transfer plate. It is thus possible to improve the weld quality of the heat exchanger.
