Abstract: A plate heat exchanger includes a plurality of heat transfer plates, the plurality of heat transfer plates including: a first heat transfer plate, including 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 includes 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.

Abstract: A plate heat exchanger includes heat exchange plates and a port, and the port communicates with a predetermined heat exchange space of a plurality of heat exchange spaces. The heat exchange plates of the plate heat exchanger includes a plurality of first heat exchange plates and a plurality of second heat exchange plates. The first heat exchange plate includes: a first heat exchange plate main body; a first opening formed in the first heat exchange plate main body for forming the port; and a first annular protrusion surrounding the first opening, adjoining the first opening and protruding from the first heat exchange plate main body toward a first side in a stacking direction. The second heat exchange plate includes: a second heat exchange plate main body; a second opening formed in the second heat exchange plate main body for forming the port; and a second annular protrusion surrounding the second opening, adjoining the second opening and protruding from the second heat exchange plate main body toward a second side opposite the first side in the stacking direction. The plate heat exchanger according to the embodiments of the present invention can simplify the manufacturing process of the plate heat exchanger, for example.
