Abstract (en)

[origin: US2020072561A1] A plate heat exchanger has first heat transfer plates and second heat transfer plates laminated atop one another, and each including a plate portion in which an inflow/outflow hole is formed, a first outer circumferential wall portion or second outer circumferential wall portion that extends on one surface side of the plate portion and that defines a channel together with a plate portion adjacent to the one surface side, and a first inner fin or a second inner fin that is attached to an inside portion of the channel. The first inner fin is mounted at a position, spaced part from a first fluid inflow/outflow hole, inside the channel, on the one surface of the plate portion and the second inner fin is mounted at a position, spaced apart from a second fluid inflow/outflow hole inside the channel, on the one surface of the plate portion.
