Abstract
A plate heat exchanger includes a plurality of first heat transfer plates, a plurality of first inner fins, a plurality of second heat transfer plates, and a plurality of second inner fins. A space is formed between each of the plurality of first heat transfer plates and a corresponding one of the plurality of second heat transfer plates. The plate heat exchanger includes, in the space, a plurality of heat transfer components connecting each of the plurality of first heat transfer plates and a corresponding one of the plurality of second heat transfer plates, the plurality of heat transfer components being interspersed between each of the plurality of first heat transfer plates and a corresponding one of the plurality of second heat transfer plates. A recess-and-projection pitch section in each of the plurality of first inner fins includes first pitch sections and one or more of second pitch sections, a width of each of the second pitch sections being wider than a width of each of the first pitch sections. The plurality of heat transfer components are disposed in regions of the first pitch sections when the plurality of heat transfer components are projected in a direction in which the plurality of first heat transfer plates and the plurality of second heat transfer plates are stacked.
