1. A shell and plate heat exchanger comprising:
a shell forming an internal space; and
a plate stack housed in the internal space of the shell, the plate stack including a plurality of heat transfer plates stacked and joined together,
the shell and plate heat exchanger being configured to allow a refrigerant that has flowed into the internal space of the shell to be condensed,
a refrigerant channel communicating with the internal space of the shell and being configured to allow the refrigerant to flow through, a heating medium channel blocked from the internal space of the shell and being configured to allow a heating medium to flow through, and the refrigerant channel and the heating medium channel being alternately arranged between adjacent plates of the plurality of heat transfer plates, and
a meandering portion being provided in a lower portion of the plate stack but no meandering portion being provided in an upper portion of the plate stack, the meandering portion being configured to meander the refrigerant condensed on a surface of each of the plurality of heat transfer plates, the meandering portion being provided by processing the plurality of heat transfer plates.
